I am currently using a 24 inch LED monitor which is hooked up to my laptop. The max resolution it displays is 1920 x 1080 and by technology standards it's fairly old (purchased in 2014). I sit a little more than 2 foot (60cm for metric people) away from the screen and not sure how much bigger I would want to go with screen size.

On occasion, I have sat in front of the screen for a few hours without taking a screen break (including the looking away into the distance trick opticians advise every 30 minutes).The following day I have really suffered for it and have eye pain as a result which ruins my day.

As some background; I have an astigmatism and fairly recently diagnosed with lazy eye which I have been given corrective glasses for. However, as I have started wearing glasses fairly late for the lazy eye, my optician couldn't give the prescription he wanted and has been ramping it up gradually so my eyes can adjust to wearing glasses. I'm probably not due for another check-up for a few months at least.

Aside from doing the obvious such as taking regular screen breaks, is it time for a monitor upgrade and would it be likely to help?

It gets a bit overwhelming when looking at monitors with higher refresh rates, resolutions, response time, aspect ratios. Then there's the decision between TN / IPS / VA? Flat or curved screen? LCD / LED / OLED?

I'm not using my computer for gaming so don't need a monitor for that purpose. Maybe a bigger screen size would help? If I got a bigger monitor is it likely my laptop GPU would be able to push out 2560 x 1440 resolution?

Any recommendations for monitors? Or whether it will even be a worthwhile purchase?

I might give that a try.

Although when I am doing general web surfing the text size seems quite comfortable.

For reference: this is my current monitor which I purchased back in 2014. I don't see anything about flicker free.

I set the brightness to 10 (out of 100). Generally I find bright screens uncomfortable to look at. Would a low brightness result in more flicker?

I will test out my laptop on my partner's giant Dell curved screen to see what resolutions would be available.

I've had a google and can't see your existing screen being noted as Flicker Free, given it's age I'd guess it's not. It wasn't a particularly common feature even 5 years ago.

Reducing brightness increases flicker on PWM dimming screens, at very low levels it can become very obvious, stobe like.

As "mmm" says it is now, so won't constrain your choices too much and sounds like something which may help hopefully. Any chance you could borrow a monitor off someone for a weekend to see if it helps?
I checked with my partner's screen and my laptop was able to push out 3440 x 1440. I have not consciously noticed any obvious strobe like flicker with my current screen.

I didn't go into it earlier, but sometimes I play online poker and have about 6-8 tables tiled over the screen. On occasion I have played a few hours in one go and there is not much opportunity for screen breaks + I imagine that I blink less. The day after playing I have felt my eyes suffer.

At some point I can try the bigger screen and increase text size.

With modern advances in monitor technology, would it be worth shelling out some money anyway for an ultrasharp / ultra HD bigger screen?

Another option may be to consider slightly tinted glasses..........
I understand that you have specific prescription glasses, but you could try getting some clip on "shades" which are meant to do the same thing.
Something like these?

For £10, it might be worth a try to see if improves your experience before replacing your monitor etc..

I noticed serious eye strain a little while back and ended up getting my eyes tested and was prescribed some glasses - which had a blue light filter coating on them.

I tried on the specs at home to work and one of my screens went almost totally black - the blue light output from screen (an LG monitor) was so extreme there was almost no other light being emitted whereas my iMac screen was identical with/without the specs!

I disconnected that screen and purchased a replacement additional screen and have never needed the glasses since and the headache/eye strain has disappeared completely
I grouped both posts as it's in similar vein.

My prescription glasses do have a blue tint on them for the blue light. I don't think the clip on "shades" would do anything beyond what my current lenses do

Before I got prescription glasses I did buy some gaming glasses which had yellow lenses. They helped a little in terms of taking the brightness out of the screen, but not in terms of helping my weaker eye.

Is your partners monitor decent?
Can you use that for a while, see if it makes a difference?

Not sure what you do on your computer, but if its something you spend a lot of time on, its worth getting a quality monitor. I guess from the Ultrasharp branding you mentioned you have been looking at Dell. Something in their P series (prefix before the number) or U series would be good. UP series perhaps overkill unless you need professional colour accuracy.

Honestly would be looking to retire something 9 years old, things move on, including in the monitor space. I mean fair enough, you may not want to bother on something used to check emails now and again, but it sounds like you do use it a fair bit.

It's a Dell UltraSharp 34 inch Curved monitor which I think is fairly decent. I haven't been able to use it for any long period but will try and give it a go. It does strike me as being a bit on the large side.

When working from home I do spend my day looking at the screen so probably worth investing in something decent. I had thought my current screen was alright but it's getting on a bit in terms of technology standards.

What size screen is optimal before it gets overpowering at around 2 foot away? 27 inch, 30 inch? Realistic budget for something decent? I don't need a super fast gaming monitor and not video / photo editing.

The earlier suggestion about increasing text size by speedyman unfortunately didn't work well with an application I was using and it struggled to fit on the screen. With increased text size I would need a bigger screen.

I checked at my workplace and they have 32'' screens - it's larger than I would like and also takes up a chunk of space.

My preference would probably be a 27 - 30 inch screen. 3840x2160 (4K) resolution. I'm still researching if there's much difference between the 1440p monitors and the 4K ones and whether the extra expense is worth it for my purposes. I believe that when it comes to gaming the 4K screens aren't good unless you have a monstrous PC. I don't play online games or do picture / video editing so 4K may be wasted on me?

Budget: I would like to try and keep it under £500.

This Dell seems to tick a lot of the boxes for me, but i'm going to have a look into other options at that price point.

Any suggestions / advice?

I suppose you have checked your laptop can drive 4k? Almost all modern ones can.

On a technical basis, that is a P series monitor and will be decent. Good quality even backlighting, good contrast, good image quality, even on brighter settings, good connectivity etc. Only real ‘weakness’ seems to be it will only go to about 300nits, which is fine in most rooms, but not if its placed in an all glass conservatory etc.

For my eyes, I found 4k 27 inch looked pretty sharp on Mac and Windows. Was very good for text based work. Also could fit a lot of Excel cells on screen if required and you could move the monitor / head closer etc.

I have a fairly old laptop (Samsung Series 7 Chronos) - due an upgrade at some point! We do have a 3440 x 1440 monitor around so I can test it out on that.

The primary use of my monitor is general office work (email, Excel, Word etc.), I may use it for some coding - my current setup does this fine.

But the main issue is when I play online poker and then suffer with eye pain the next day - partly due to smaller font and also not taking breaks. When I play, I can only tile 6 tables on a 1080p screen and there is some overlap. The font is also a bit on the small side so a larger screen would help as I could increase the text size. More pixels would mean I could fit more tables on the screen and not have an overlap. Admittedly, 4K might be overkill for my purposes.

I have seen some other brands (BenQ, Asus) where I can get 27 / 28 inch 4K for under £400). I'm not sure whether these are better / worse than the Dell.

Speakers are not really a factor for me.

Generally when I read reviews of monitors with speakers in them the feedback is that the speakers are poor. I think that I would rather the money is spent by the manufacturer towards a good display rather than compromise the display at the expense of including some speakers.

It feels a bit limited for 4K screens which are £500 or under. I saw this screen on Amazon - claims to be 4k, 28 inch, anti-flicker. It's almost £200 cheaper than the Dell so am not sure whether corners are being cut.

Currently, I do have a Hub to connect my work computer to. I don't have any real need to connect lots of things into a screen.so that functionality is probably a bit wasted on me.

Thanks for the advice on this, it's greatly appreciated.

I did notice the BenQ is not height adjustable. That seems a good feature to have - although looking at my current screen it's fixed height.

When looking at the Dell P series monitors: 27 inch, 4K - there are 4 options.

This one for £329. This for £369. Then we have the £482 one which I posted previously which has lots of ports. Finally there's the £640 Ultrasharp screen

So what's really the difference between them all? £329 & £369 both have speakers. The £369 has USB-C whereas the £329 does not appear to. Or I can pay an extra £120, which loses the speakers and gains more ports has Comfortview Plus (instead of Comfortview on the £369).

I'm not really what would make the £480 screen have a better picture than the £369 one based on their specs.

This bit jumps out at me. Why do you need the monitor to be so dark?this suggests the ambient light is very low and you need to reduce the brightness to reduce contrast to the surroundings.

I used to get bad eye strain when I first started WFH because my workstation is in the corner of the room and it's quite dark, especially on late afternoon winter days. I now tend to run most applications in dark mode and have an LED desk light to increase ambient light locally and don't have the same problems. Your monitor should not be illuminating you IMHO.
I find it can be quite piercing to look at a bright screen for a long time so tend to dial the brightness down as it's more comfortable on the eyes.

In terms of lighting; I don't currently use any desktop lighting and either use natural light (if it permits) or turn on a light if I find it a bit dingy. I do have a desk light which I could use but have not felt a need to use it.

Are you looking up independent reviews?

https://www.pcworld.com/article/630195/630195.html
Is anything really ever independent? tongue out

I did have a look at Which? magazine and took the lazy option of watching some reviews / buying guides on YouTube. I had not made it as far as the review above or cnet / techadvisor reviews yet. The PC World review gives it 3.5 stars (out of 5 I assume). The technical tests certainly go over my head but based on the article the P2723QE performs slightly above average.

Based on the article, none of the monitors really excelled in all areas - there is some compromise with the specs along the way. The Asus performed well in max brightness, Delta E and not so great in contrast ratio and colour gamut.

The U2723QE has contrast ratio of 2000:1 according to Dell vs 1140:1 (PC World spec) for the P series. Brightness 379 for the U and 314 for P (the Asus ProArt is 452 and sub-£400). The colour gamut for the U looks much better than the P too. The UltraSharp is obviously a superior screen to the P and one does pay for it.

So the question is:

1) Am I really going to notice the difference between using an UltraSharp and a P for office based work / internet browsing / YouTube and some online poker?
2) If I push the budget out to £650 for an UltraSharp - are there other screens I should be considering in that price range instead?

I have a 27" widescreen 2K monitor (Asus Predator), and would say that's probably about the right size/spec for the OP's requirements. My work laptop with basic onboard graphics has no problems driving it. Not convinced 4k is worth it unless you're planning to play games or watch films on it.

Also think about the lighting around you. I find the sun behind my monitor, or directly lighting the wall behind my monitor, causes me problem, but also using a monitor when it's dark around is a problem. For the latter I've just bought a Benq Screenbar which works really well at illuminating my desk without spilling on to the screen.
This is actually the first I have heard of the screen lighting. It looks a good idea and interesting.

It's probably one of those things you didn't think you needed until you start using it.

I'm currently in a fairly well lit room, I don't feel that it's especially dark or has much glare - i'm not aware that an issue exists with lighting.

Yah, I ignore their subjective ratings and concentrate on the technicals, depending on what I want out of a screen. Those reviews also focus on features for the RRP, when as a customer you can get lower prices / refurbs / deals, esp. on Dell products.

Its just like cars, I’ve driven very well reviewed products I absolutely hated, BMW are a stand out. Objectively I can’t say they are bad, but they are not what I’m looking for out of a car, (possibly front drive models excepted, which I don’t have experience of).

At the Ultrasharp level, some LG Ultrafine models come to mind which are comparable. The Dell Ultrasharp actually uses an LG panel.

And no, I don’t think Ultrasharp is worth it for your sort of use, but then ppl also drive Range Rovers in congested London traffic for the school run, so each to their own. You will definitely be getting a better monitor.

Edited by wyson on Thursday 23 March 17:15
Going back to the P2723QE, relative to the monitors compared against - the max brightness is on the low side (314), colour gamut is a bit unbalanced and colour error is slightly under 2. These specs would suggest it isn't anything exceptional but to the eye may very well be a nice picture.

For someone coming from a 1080p monitor to buying a 4K UltraSharp is a large step and probably selling myself something I don't need - arguably I may not have much need for 4K. One always wants the best for the money and to get the best possible. Being sensible, it comes down to whether the additional cost is really justified or wasted.

I think it will have to be a case of narrowing it down to a few monitors and then read a load of reviews. Then i'll probably be not much wiser and buy the Dell hehe

I would definitely go for 4K over 1440p. I've used all the resolutions, my daily at work is actually a 1440P 34" Acer monitor, designed for gaming, and it's fairly sharp, and certainly noticeably better than a 1080P monitor, however, I've also compared it with a 27" 4K monitor and the 4K monitor was a clear step up again, and gives very natural print like text and icons when scaled correctly.

I wouldn't be surprised if you could get 2x 27" 4K monitors for not much more money than a single 34" and it will be better for productivity I reckon.
That may be true. The limiting factor becomes desk space.

I use a 32'' at work and it does feel a bit on the large side. Unfortunately there do not seem to be many options between the 27/28 inch and 32 inch.

Yes, you're not wrong, a 34" monitor is considerably more compact than 2x 27's, even 2x 24's. I think it's personal preference at this point, but out of a 27 and 32" 4k monitor I'd go with the latter and try and get used to it. With a resolution and size like that, you could feasibly get a usable window in each corner, but equally, if you need everything to be a normal size, everything is going to be pin sharp and detailed.
Damn.....this confuses my brain even more and makes me second guess myself hehe

I use a 24 inch currently and it's pretty comfortable. At work the 32 inch does feel a bit on the large side.

I'm sure that it's something one gets used to, but it will take up extra desk space and i'm not convinced that it's necessary to have something 8 inches bigger than I have now.

From a budget perspective: I could maybe stretch to a 27 inch UltraSharp which is meant to be a very good monitor. If I buy a 32 inch i'll be getting something of lesser quality. A 32 inch UltraSharp is closing in on the £1k mark which is pricey for my means.

Would I really notice much difference between a 4K P series and an UltraSharp? Possibly not for what I do on the computer.

So do I go bigger and compromise on some tech specs on a sheet which are possibly not noticeable to my eyes?

Some general thoughts.... I'm short sighted and also have an astigmatism so can relate.

I spent years not spending much time on PCs and my eyes were fine, but when I got a desk job they were terrible for the first few weeks with bad headaches as my eyes were then doing a lot more "work" (focusing) than they had been. I now find that in general, in a well lit office with natural light, I can work happily without glasses, but if my eyes start getting tired then I get headaches. Tonight I'm working nights and didn't have much sleep last night, so am wearing glasses even though my eyes feel fine - it's better to make life easy for them rather than me ending up knackered with a headache by 7am tomorrow.

Screen wise, I have 4 32 inch monitors arranged as a square and find that QHD (2560*1440) is perfectly fine, so use an older version of these, which are only £190 each. A modern Windows laptop should be able to run 2 QHD screens using Display Port technology which is built into Windows.

Edited by Condi on Saturday 25th March 22:22
I think the lazy eye is probably the bigger issue than the astigmatism, although wasn't something I was consciously aware about until the last 3 years or so. I've always had one eye working a lot better than the other and compensating for the bad eye. I now have corrective lenses but over a prolonged period looking at small text I would probably suffer from it the next day.

The Viewsonic is certainly a lot cheaper than the UltraSharp which I was thinking of getting. Although I think 2x 32 inch monitors is probably pushing it for what I can fit on the desk.

Eye strain is all about the brightness and lighting. I was suffering from eye strain until I started using a Benq light bar plus, works wonders and no more eye strain regardless if ambient light in the room day or night.
This was going to be my next question about the light bars.

They seem to range from £20 - £120 for the BenQ plus.

I don't really work in a dark room, is it going to noticeably improve things to use one? I'm wondering how a light shining on a monitor is not going to cause reflections / glare on the screen itself.

The Xiaomi for £50 seems to have positive reviews. Is BenQ plus really that much better to justify the additional £70?

Well i've gone and done it....just placed an order for a 27 inch UltraSharp tonight.

I had a look in Currys today at 27 inch monitors to get an idea of size. It did seem noticeably bigger than my current one even though 3 inches doesn't sound much bigger and was still comfortable on the eyes. I could have gone for 32 inch but then will be compromising on resolution.

Read some more reviews online which seemed to generally be very positive about the screen. I'm not sure it's the very best screen out there, but neither is it the most expensive. Maybe a 1440p would have done the job too.

It's a steep amount of money for a screen and quite possibly a tad overkill but hopefully I can get 6% cashback on the transaction and my employer will contribute £100 towards the screen to slightly soften the blow.

Thank you all for the help (especially Wyson for checking out the spec sheets). Next thing is whether to try a monitor bar but will see what I think in a few days.
