Are they all equal?
I have an HDMI cable that says it supports 1080p video.
Should it allow me to obtain 2560 x 1440 resolution from my graphics card to my
monitor (which has no DVI input)?
At the moment my max resolution is 2048 x 1152.
While not all created equal most will handle this resolution without any problems.I have an HDMI cable that says it supports 1080p video.

monitor (which has no DVI input)?

There are only four types of cable: -
HDMI
HDMI + ethernet
High Speed HDMI
High Speed HDMI + ethernet.
Don't let anyone tell you HDMI cables have version numbers etc.
The only reason to really get a high speed HDMI cable would be for 4K/UHD.
I hear Amazon Basic cables are very good, no need to spend silly money.

Had a few of the amazon basics ones, seem very good quality, well made and do the job, someone will always try to sell a hundred quid one, a big upsell thing for tv's based on someone spending a grand and don't want to compromise their new purchase with a cheap cable, have used an expensive one, zero difference to me than the amazon or any other cheap one.HDMI

Someone at work was saying you can pay a grand for speaker cables and another 100 for them to "run them in", that is top level b
ks !You need a top of the line, highspec cable for that,
I prefer to get http://www.poundland.co.uk/signalex-hdmi-cable-1-m... bit pricey but well worth it, I wouldn't scrimp on your cabling.

Slight thread hijack, but what are the ones Sky use? Are they different?
Just upgraded to SkyQ and got another HDMI with the new box, so had a spare which I've used to hook up our DVD player. (Old Skool!) The Sky cable is terrible with the DVD player - really jerky picture and no sound to the TV (DVD player does surround sound), is it a different spec?
I can see I might have to get one of those from Poundland, how much do they cost?

According to the manual
http://downloads.dell.com/manuals/all-products/esu...
It can only do a max of 1080i over HDMI.
Im guessing you would need to use the display port.
Also, QHD would have t obe at 60hz.

According to Amazon reviews it seems to work ok for some on HDMI, but others have reported that it requires Display port to get the optimum resolution.
As above, a lot of video cards will struggle with anything over 1080p over HDMI, but also not all displays will accept anything higher than 1080p through their HDMI in.
For example, my Dell XPS can do max 1080p over HDMI out (DP out does a lot more).
For both my monitors on my fixed computer (1440p in 16:9 and 21:9) I use DP, but I had to buy a GPU as mine wasn't capable of producing a 6000x1440 image.
If your pc has DVI, as above, I'd suggest looking into a DVI -> HDMI adaptor.

HDMI cables transmit ones and zeros, the quality of a one or a zero doesn't matter, it's either a one or a zero.
True, but at higher frequencies cables need to act more like 'wave guides' than true conductors.This is borne out in the bend radius limits on Cat 6 cables, at high frequency, with a tight bend, the signal (the 1s & 0s) aren't travelling through the core of the conductor, they are being guided along its surface. A tight bend can mean much of the signal simply goes straight on into the dielectric layer and then be grounded by any shielding.
If you ever get the opportunity to visit a satellite ground station, or even just get on a roof top with GSM 3/4G mobile phone antennas, take a look at how the antennas are connected. It is isn't with conventional dielectric coax cable, it's all done with a copper corrugated tube, often a few inches in diameter.
Sure, over short distances you can pump 4-5 GHz down a conventional coax, but any tight bends will cause problems.
Losses in very cheap cable can be a problem. The upper layer protocols should be able to compensate for a mediocre cable if the run is short enough.
