Monitor displays abnormalities when turning on "Ultra Low Latency" in the OSD. The issue occurs ONLY when the "Ultra Low Latency" Mode is turned ON, and the monitor is set at 144 Hz. This is the only scenario where the abnormality occurs. If Ultra-Low Latency Mode is ON, and the monitor is set to 120 Hz or below, the monitor works perfectly fine. Likewise, if Ultra-Low Latency Mode is OFF and the monitor is at 144 Hz or below the abnormality does not occur. I have also ruled out any Windows, software, video card, hardware, and cable issues with multiple tests. There have been no cosmetic damages to the monitor, never have been dropped or knocked, the issue suddenly occurred. Will appreciate anyone attempting to help, has any info, or have a solution.

Images below of the issue.

    Remove all the cables from monitor.   Press and hold the power button of monitor for 1 min.    Connect all the cables back.  Try to turn on the monitor.   Connect the monitor to computer and check. If the cable is non removable please don't try to remove it. 

    Try to use alternative cables and check if possible.

    On the monitor – use the control buttons.   There will be an option to reset monitor settings to default.    Try to reset the monitor and check.  

    To isolate the issue, try to use the same monitor to a different computer and check  or  Try to use an alternative monitor on this computer and check.
