Q about GTX 1080 and multiple screens

[mistersprinkles]

I have a GTX 1080 G1 Gaming. I have a 1440P 144Hz display, a 1080P 60Hz display (DP and DVI) and today I tried to hook up a 3rd display, a 4K TV, using an HDMI 2.0 cable.

I was unable to get a display to show up on the TV and my computer was freezing up and icons were flying around my screen and the mouse pointer would appear and disappear and nothing was responding to any commands.

Is there a limitation on my card preventing me from using these 3 displays? Or is the HDMI cable defective? Thanks.

Try lowering the refresh rate to 60Hz before setting it up. I don't know how much a graphics card likes running multiple refresh rates...

My 1080ti runs a pretty much identical monitor TV setup you have with no issues. 1440P 144hz DP, 1080P 60hz DVI, 4K TV 60 Hz HDMI. Plus I did have a 4th 1080P @ 60hz monitor running though a DP - DVI adaptor at one point.

I don't think the GTX 1080 display outputs are any different.

I would suggest trying to connect just the 4K TV on it's own if you haven't done so all ready to make sure there not a problem there.
