I have six screens. I need six screens. At the moment I'm using three different machines to drive them but it's a PITA so I want to build a PC with six HDMI outputs. I assume there is no such graphics card but is there one with three HDMI outputs? If so, I'd just buy two and run them that way.

I assume three cards, each with two HDMI outputs will be hard to fit into a PC.

I only need 1080 resolution, nothing greater.

My Google-fu has failed to find any (that still exist).

Multiple graphics cards.
Assuming fairly static screens, usb to hdmi might be an option.

Or, a couple of massive screens (ultrawides) and many windows.

Do they all have to be HDMI? I know some GPUs have 4 display ports and two HDMI.

I recall that Matrox made a 6 output graphic card; normally used on the trade floors (c680).

What are you wanting to display over the 6 screens?

I have an EyeFinity card with 6 Mini Display Port outputs. I use it with a mix of HDMI, DVI and DP monitors, you need an active adaptor for each output, but it'll run 6 x HDMI no bother.

The card was £100 or so maybe 5 years ago second hand and does 6 x 1080, but not 4k.

I wouldn't go for two graphics cards as in my experience they cause havoc with moving applications around screens on wake-up as one card tells Windows it's there slightly before the other. Nothing more annoying that having 50 applications spread over 6 screens and 5 virtual desktops all dumped onto a single screen and a single desktop!

Anything wrong with this?

I can buy cables to suit the monitors I have for a fiver each. This seems too good to be true.

Few different options here -

Depends on whether your existing monitors have HDMI/DisplayPort, whether you do gaming etc

I thought I needed HDMI but I don't. DP is fine. I can get cables that'll convert very cheaply.

Thanks for the suggestions. I'll look through them now.

Yes there is something wrong with it - it's fussy with cables. You need active adapters for this - whatever they are. More Googling...

Could you run it with 6 active mini DP to DVI cables?

Yes, I think so. I did it with adaptors because it was less clear whether the cables were active or not and it's a bit more flexible in future if you get screens with different inputs as you can get a HDMI to DP etc cable and swap it in.

May I ask why 6 screens out of interest?

Seems like an expensive way to do it?

I used to use two graphics cards (or at least, onboard + a graphics card) for three monitors years ago and had no issues.

My GTX980 supports three monitors without issue and you could use two - obviously the GTX980 is an expensive graphics card, but I'm sure other models support it too and are less than £300 for a pair.

Two screens for Excel, one for BlueJeans VC (our corporate standard), one for a different (customer/supplier) VC (often on at the same time - Google Meet, Zoom, WebEx - that can be a challenge to manage), one for a Citrix client, and one for a piece of UPS monitoring software or server VMs.

I could do all of this on ultra-wide screens but I have the screens already, and I don't need the additional resolution. I thought a 6-way graphics card would be cheaper than changing the screens. Also, the screens are slightly messily arranged, around the available space I have.

At the moment, I'm running three separate machines to power all six screens, with three keyboards and three (blind) mice.

you can daisy chain Display port connections depending on graphics card and screens having in & Out ports.

If you dont have enough graphics card support for 6 you could look at VGA and HDMI'ing the rest

LOL, sounds like a proper mess. If you need to carry on using multiple computers, have a look at KVM switches, so you can at least get down to a single mouse and keyboard.

Someone always asks why someone needs so many screens, I can't understand how people work off one or two. I have one for Teams, one for Outlook, one for looking at the data I'm working on, one for working on, then I have one for Pistonheads and one for Youtube/Music/Tweetdeck.

Then I use Virtual Desktops with things like Teams and Outlook set to show on all desktops, so I can cycle between different projects.

The price of 6 chainable monitors is going to be a lot more than the price of a 6 screen graphics card. And you'd still need to buy a card that supports 6 screens.

biggrin It totally is but it's grown organically as I've needed it, and I quite like it now - apart from the multiple input devices anyway.

I didn't even mention PH, YouTube, WhatsApp and Facebook Messenger. I actually have a 7th screen in the garage I have been wondering where to mount and how to use but I want to solve this problem first.
