    Color quality, Refresh rate

    Sad day for me

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    As much as i loved this monitor when it worked. It was amazing and colors pop and speed was unmatched, but it severely suffered from black screens and flickers esp when switching from freesync and hdr on and off. Sometimes the screen will go black and never come back on and you can still hear the sound in background. I tried it 2 times as i exchamged the first one thinking it was faulty but sad to say i think it was a software issue maybe idk. Im sad i had to return

    No, I would not recommend this to a friend

      Hi, Ruben. We appreciate you sharing your experience with the LG Monitor (27GX790A-B) model. We understand your concern about encountering black screens and flickering issues, especially given how much you initially loved the monitor’s performance. We strive to provide reliable, high-quality products that exceed our customer's needs and expectations. For similar display concerns, we recommend updating firmware & drivers – Check for the latest updates via LG's support site and your GPU manufacturer (NVIDIA/AMD). For guidance, you may visit https://www.lg.com/us/support/help-library/lg-monitor-how-to-update-monitor-firmware--20153819322140. Testing different cables & ports.

Try disabling VRR (Variable Refresh Rate) or HDR separately to see if stability improves. Power cycle & factory reset. Unplug the monitor for a few minutes, then reset it via the OSD settings menu.
