You didn't edit the final row of numbers. Also, are you using HDMI or DisplayPort, because I was only able to achieve the overclock with DisplayPort.

Asus X99-A w/ BIOS 3402 | Intel i7 5820k OC @4.4GHz 1.28V w/ Noctua NH-U14S | 16GB Corsair Vengeance DDR4 OC @2666MHz 12-14-14-28 | Asus Geforce GTX970 STRIX OC | EVGA 750 G2 750W | Samsung 850 Evo 1 TB | Windows 10 64-bit | Be-Quiet Silent Base 800 w/ Silent Wings | 2x Dell U2414H OC @72Hz w/ Display Port

Ah I see what you mean, I didn't update the total pixel row, was greyed out in the first example but had the other settings there. What does that "total pixels" setting actually do?

Anyway I tried it and got 72Hz working right away with these settings. Did the UFO frame skipping test and no issues there, thanks a bunch!!! I have it hooked up via HDMI btw, don't have a DP cable lying around here to test.

Update: tried with a DP cable but could not get higher. It almost seems the monitor has a fixed "lock" on higher refresh rathes than 76hz because anything 77 and up will fail, even on 1280x720 resolution with a pixel clock of <100. Guess I'm stuck at 72 then, may have to start looking for a better screen smile.gif

This is normal, 75-76Hz is the maximum specification for most 1080p60 panels (including U2414H panel)

I would not recommend to force higher timings than max specified. On most monitors the scaler doesn't allow it anyways (many don't even let you get to the max)

But max spec doesn't usually mean it cannot run higher, right? rolleyes.gif

But indeed preventing higher rates by locking it makes sense to prevent display damage and RMA's from people like me messing around. Thanks for the reply might have to start looking for a good 144Hz panel... now to decide if I can live without my precious IPS tech frown.gif

1440p?

2560x1440p on a Dell U2414H? I don't believe you...
