Adding a cheap gpu to power 4th screen

[Petro1head]

i currently run a 24” tripple screen setup. I have added a 4th screen with is powered off the hdmi of my 1080ti

I would like to upgrade to 27” screens running quad hd (2k) so will need all the power to run the three screen.

So would it be an idea to buy a cheap gpu to run the 4th screen. This screen simply runs the std windows apps

That won't work, mixing differing GPU models won't be recognised unless you buy another 1080 Ti and run in SLI.

I was not looking at sli. I want to use the 1080ti to run the tripple screens and another card to run a separate monitor

I know which is why I said it won't work outside of SLI with another of the same GPU model.

You might not even need to buy another GPU even if it would work. I used to run a 4th monitor off my motherboard graphics port for extra dashboard software. I think I read on a forum somewhere that it may induce some lag if you are very particular about that kind of thing. Honestly I never noticed it though. I had to enable motherboard graphics in the BIOS to get it to work but it definitely works.

I once used a usb to hdmi converter to do something similar.
But it was a single monitor on the Gpu and a small monitor on a usb-hdmi.
Also if I recall right i use it as extended monitor and not sure if it works any other way.
