Added 3 1440p monitors - Aero stopped working

So I was using 4 x 1080p and I just swapped out 3 displays for 1440p. However, right after, Aero stopped working on my Win7. When I unplugged 1 of the 1440p DVI, it works again. Is there some sort of single card limitation? I'm currently using GTX 770 4GB.

Do I need to buy an additional video card to power one of the 1440p?

I'm not sure why that is but a single GTX 770 is not anywhere near enough for three 1440P monitors.

I'm not gaming on 3 1440p, I just powering 3 with 1 card. I didn't think it would be an issue. If I do play games, I only play on the middle screen.

Right now I'm confused as to if this is a Windows limitation or not.

The GTX 770 has a maximum digital resolution of 4096x2160. Perhaps the 2560x1440 monitors exceed the max resolution for your video card?

Can you lower the resolution of each one to like 720p and work your way up? Does the 3 display setup work at lower resolutions? If so, you are probably limited by your video card.

Ok I fixed my issue. I installed the Intel Onboard VGA drivers and I plugged one of my 1440p monitors using a DisplayPort into my Mobo, and ran 2 1440p + 1 1080p TV off my GTX 770. Now I am still able to run Aero.
