If it's not a TDR, then the blackscreens you're describing sounds like they may just be the monitor taking longer than expected to re-sync during a screen-mode / resolution change.

[*This exact situation happened on my Dell U3014 'until' I switched to DP, where the monitor would blank for a minute unless I flipped the power off/on*]


My gut reaction was going to be suggesting that you try plugging the monitor in using DisplayPort instead of DVI-D ... yet it looks like the screen doesn't take DP, so that's off the table. Only other thing I can think of is playing with CRU (ToastyX's Custom Resolution Utility) and changing settings to lower your pixel clock 'slightly', then seeing if this reduces or eliminates the times that the display blanks abnormally long.

--Powercycling the monitor during a blackscreen does nothing? (if it doesn't do anything, don't bother with the above)


Also, if you've used the NVidia ControlPanel to Overclock your panel, remove those settings. Without registry editing the custom resolutions applied through the NVidia CP won't be used in games (causing a swap to the higher refresh on the desktop only).


Since it happens on alt-tab / focus loss, D3D device loss, display-mode change, etc.. Have you tried putting the game in borderless windowed mode instead?

-If you haven't, then that's probably the easiest workaround .. provided that you're not playing in Stereo3D and you don't mind not having the engine's presentation truly synced to vsync (wouldn't matter much with a 120hz screen anyway, still should be silky smooth).
Thanks for the intelligent reply.

Two answer your last question, yes I have changed settings to borderless, although this technically isn't full screen (even though it looks like it). The only problem with this, is the mumble names don't appear on the game. But there is no black screen during alt tab, I can see it running smoothly in the background.

I haven't tried turning the monitor off/on, but I will see if that fixes the problem next time it happens.
