Hey guys, I currently have a Dual monitor setup with 2 x Dell 24" flat panels and a single AMD7970 card. In the past I've just played BF4 on a single screen at 1920 x 1080 and it work great. Lately however, I've gotten to think about getting a third monitor to try to run the game spread across all the monitors with a larger field of view. I ran the game on two monitors and it ran fine, but the obvious issue of the aimpoint being between the monitors doesn't really work. I ran it windowed just to move the aimpoint over and check if it was playable and it ran great.
So, now I'm thinking of getting a third screen and trying them all together.
Here are my questions.
1) do I need a matched screen?
2) will my sapphire HD7970 output to 3 screens?
3) do I need another graphics card for memory or performance?
thanks for the help!
I just upgraded to a three monitor setup. I get around 40-60 FPS depending on the map in BF4 with my 7950 @1100/1500 and a 2500k @ 4.6Ghz. Settings are Ultra except running SSAO instead of HBAO and only FXAA. My FPS stays near 60 until there is a huge amount of stuff on screen at once. You could likely turn up settings if you don't mind lower than 60 fps average. The actual resolution I run at is 5329x1050 (1680x1050 + bezel correction). I get a bit disoriented without bezel correction in first person games so I would recommend having it on. It does effectively increase the resolution you must render. Suggested FOV for 3 monitors like that is around 105, which is what I'm running and its very comfortable.
So to answer your questions:
1) You do not need a matched screen, not even same resolution as long as it can run the same resolution as the lowest resolution monitor.
2) 7970's can run 3 monitors BUT can only run TWO DVI at once. You will need to have at least one of the monitors running via DisplayPort as the RAMDAC that runs the DVIs also runs the HDMI. I just got a single DisplayPort Mini to DVI adapter on amazon and ran the other two on the DVI + HDMI.
3) Your 7970 will run it well but you may need to turn MSAA off to do it if you want to stay at 60 FPS. I suggest overclocking your 7970. That will most likely be enough. I am personally upgrading to a R9 290 so that I can keep my AA on
