So I have 4 monitors all are the acer h233h model, 3 of them are connected just fine working as one screen through eyefinity and I wanted the 4th one to be just a secondary screen. but when i connect it to the computer it comes up as no signal regardless of what port i have it in, DVI or HDMI. It comes up in the device manager as a generic pNp monitor. my graphics card is a gigabyte r9 390 which has support for up to 4 monitors so I'm not exactly sure why this isn't working.
I'm running windows 10 if that helps at all, and all my drivers are up to date.

when I try to do that for any option it says that the display settings could not be saved. please try a different combination of display settings.
 
Sounds like you're trying to duplicate it, a setting of 5760x1080 obviously won't stick. You're sure you have it set to Extend and selected 1920x1080?

I guess i would start over. Get all 4 monitors working NOT in eyefinity, THEN set up eyefinity with only 4.

so I disabled eyfinity, it still won't connect to a total of 4, it doesn't give me the option to change resolution but the three that are working are all set to 1920x1080

3 being display port, and 1 being hdmi. I also have a connection for DVI but changing one over to that didn't change anything

ye, I can connect to any of the 4 but only 3 will work at a time. ive also tried different brands from acer as well as the scepter brand but it still ends up being the same problem
