At 85 and 100hz the screen is bright and vibrant. at 60/120/144hz the screen appears to automatically dim. I can confirim this by changing HZ's through Nvidia Control Panel

    hunterhopkins87,

     

    I'd like to try and research this for you if possible.

     

    • Are you using the default color settings when the unit was first taken out of the box or have you made adjustments? If you've adjusted them, would you please post what the OSD adjustments are so I can try and see about duplicating it? (eColor management setting, brightness, contrast, gamma, color temp, DDC/CI)
    • What video card are you using?
    • I'm wondering if you turn off DDC/CI if that will make a difference, it looks like it might be on by default.

     

    Look forward to your response.

    I have tried two displays and they both do that. I prefer the dimmer frequencies though Smiley Happy

     

    My problem is that the display flickers / flashes every few seconds or minutes. Very irritating. Both displays have done this with two different cables (Acer cables). Using drivers 347.88 because the newer ones lock my games hard on loading screen.

    Tried the new driver 352.86? For me the brightness difference disappeared and there is a lot less flashing/blinking now! Perhaps it is all in the driver.
