There is a newer firmware of 1006.2 available but i am not sure if it will help. With either firmware i can’t get my screen to be set at 240Hz. It just goes black. I can set the screen to 240Hz with Gsync on but if i run a game or desktop and check the screen refresh rate under the “Information" section in the screen menu it always says 120Hz. Also the game settings are locked to 120Hz. If i change the "Nvidia Control Panel" or windows "Display settings"  to 240Hz the screen just goes black and i have to reset it all to 120Hz to get any image to display again. I am running on a 3090. It looks like we are not the only ones but i wonder if anyone has it working at 240Hz.

I saw that and updated right after. Just tested and nothing has changed. This is crazy, $1700 and have to deal with all of this? This monitor is gorgeous and its such a shame

FYI, 1080ti can't support 240hz @ 5120 x 1440. It doesn't have a hardware DSC to support that bandwidth. You need to setup to the Nvidia 20xx series or 30xx series  cards to get 240Hz. However, there is a driver issue with the 30xx series now that can't support 240Hz (Nvidia is aware of the issue)... but 20xx series certaintly is supported full resolution, 240Hz. 

 

For your reference, you can do 240Hz @ 3840 x 1080, 2560 x 1440 on your 1080ti, assuming that is what you have. 

 

Source: I have a G9 and 1080ti. I don't have any flickering issues with my G9.

Your post gave me so much relief! Spent ages trying to trouble the flicker caused by G-Sync. 


My laptop has a GTX 1070 Max Q, and I can confirm I am able to run 240Hz @ 3840 x 1080 without any flicker - Overwatch and Rocket League running smoothly at FPS above 110-120. 

A GPU upgrade will be needed to get the most out of this for sure!
