Recognizing the Need for a Reset

Common Issues and User Experiences

Vertical Lines and Flickering: A recurring issue with the X34 is the appearance of vertical lines and flickering, especially when overclocked to higher refresh rates like 100Hz or 120Hz. For instance, a user on Reddit (source) mentioned experiencing RGB vertical lines when overclocking their X34. Another user faced similar flickering issues at 120Hz.

Overdrive Setting Troubles: Some users have found that adjusting the overdrive setting in the On-Screen Display (OSD) can resolve certain display issues. Overdrive helps reduce input lag but can sometimes lead to display problems.

Standby Mode Glitches: There are instances where the X34 fails to enter standby mode correctly, staying active with a blue light and backlight on. This issue can prevent the monitor from turning on again, requiring a reset.
