New Graphics Card Won't Allow Me to Use All 3 Displays

[otobot9]

He guys so I recently upgraded from an AMD 7790 to an AMD 7850 because my friend sold it to me for cheap. (I know it worked properly for him the same day I got it) Anyways my problem now is that I cannot have all 3 of my monitors on at a time. I have 2 connected via DVI and 1 connected via hdmi because that is it's only output. If I press Windows + P to bring up the display options I can click on PC screen only which turns on only 1 monitor or I can click on Second screen only which turns on my other two. If I click on extend it will say that it is selected but no actual change will occur, the same with duplicate. I have tried reinstalling drivers but nothing is working. Any Solutions?

 

Edit: Just tried with only two monitors and I can use any combination of two but three still doesn't work.

If those are DVI-I and DVI-D ports that should work normally. If you're using a splitter on 1 port then yea you can only get the same image on that port, no matter how many splitters you hook up on it.

 

Solution: Assuming your CPU has onboard gfx, hook 1 monitor up to your mobo. (Be sure to enable integrated GFX first in BIOS or check if it's on)

Yes it is the same setup as on my old card that was working I am not using a splitter it is two different ports. Are there any downsides to onboard graphics? I feel like that should be a last resort.

If you're gonna do eyefinity then yes that will cause problems. But since you have a 7850 I don't think you will do 3 monitor gaming. There's no real downside on it if you're just gonna use the monitor ( the one connected to the mobo) for skype or steeam or a chrome tab.

Just tried this and the same thing is happening. All monitors work independently or in sets of two but not all three.

Hmm that's really weird. I have 3 monitors myself and I've ran 2 from the GPU and 1 from the mobo for the longest time. Also on an AMD gpu. 

 

Are you 100% sure that it's 2 different DVI ports?

200% Certain. Thats 100% for each DVI port.

what processor you using? not all amd cpus have onboard gpu. or, it could be disabled in bios? i know i disabled by my intel igpu to get rid of the weird bios display to an unplugged device on igpu hdmi output.
