U2518D, screen tearing, slow rendering

I've seen a few discussions about others having this issue with the U2518D. While gaming it seems like the rendering stutters or lags causing visible tearing. Makes gaming on this monitor incredibly frustrating at best. A brief rundown on what I've done to try and address this issue.

- Updated the firmware to the latest M2T103
- Set response time to "Fast"
- MST set to OFF
- Dynamic contrast set to OFF

I have this monitor connected to my Nvidia GTX 970 via DP 1.2. I'm trying to play games @ 1920x1080 resolution at 60Hz refresh rate. This monitor has brilliant colors, contrast and lighting. But I'm coming from a 7 year old 24" Acer that had zero rendering issues, if this can't be resolved I'll be taking the two I bought back to the store for a refund. Has anyone made any headway regarding this issue on these Dell U2518D's?

Thanks!

Can you test those games or any games at 2560x1440 60Hz and replicate the issue? Can you replicate the issue on a system with a newer Nvidia video card?

I've also tested at the native 2560x1440 @ 60hz with the same result. The game I'm playing is Battlefield 4, the GTX 970 is rendering the game on average at 120fps, I don't think its an issue with the PC or GPU as my old Acer monitor had none of these issues.

The U2518D is locked to 60Hz when set to 2560x1440 and 1920x1080. By allowing the GTX 970 to render above 60FPS, you are causing the tearing. Restrict the graphics card and game to 60FPS. Then retest.

If you want higher Hz and FPS, consider the S2417DG 165Hz, S2716DG 144Hz and the AW2518H 240Hz that support G-SYNC.
