I have 2 GTX760 2GB, my new monitor is an Asus MG278, I bought this monitor to try out the 144hz refresh rate, all the video options only show 60hz, 100hz and 120hz, I'm currently using  361.43 drivers. Is it my monitor, drivers or does the card not support this? Some games do not work above 100hz, screen just goes blank and I have to reset. I'm using Displayport 1.2.

    From doing a bit of research, that resolution and refresh requires a pixel clock higher than the GPU can output. Short answer is no, your GPU doesn't natively support that combination of refresh rate and resolution. There's a couple of tricks where you can possibly eek about a few more hz, but 120hz is pretty much your top end at the refresh and resolution you're trying to run.

    Thanks for the info, I thought my cards were capable because Max Refresh is listed as 240Hz and Max Digital is 4096x2160. I've been trying to look up Pixel clock specs, how is that calculated?

    In the monitor's on-screen setup (System Setup -> DisplyPort Stream), I do believe there is a setting for selecting DisplayPort version 1.1 or 1.2 and the default is DP 1.1 and you need to change it to DP 1.2..That is just my guess.

    Right. But those max values are not the GPU is capable of simultaneously. In other words, you can't run at 4K at 240hz. You could run 4K at 60hz maybe a bit more depending upon the display.

    Yes, the DisplayPort only supports 1.2 on mine, I thought I did enough research.

    I thought I could run either one card or both at SLi at 2560 x 1440 @ 144hz, as you mentioned I guess I didn't understand the stated cards max specs that are listed as higher than what I wanted, useless to ask the people at the store. So I'm currently at 2560 x 1440 @ 100hz, though 120hz is listed, some of my games crash if I go above 100hz.
     
    Thanks to all who have replied.

    The only thing I can advise is to unlock the full potential of the MG278Q, you will need an AMD graphics card, not the oldest one. However, monitors supporting two technologies at once, and AMD FreeSync, and NVIDIA G-Sync, do not exist in nature and are unlikely to ever appear.
