Hi everyone,

I own an LG OLED Flex 42LX3 purchased in August 2023 and right after installing the latest firmware update today, (33.31.24) I noticed a strange rectangular artifact appearing in the upper-right part of the screen.

It is visible on every source:

• HDMI
• internal apps
• menus
• dark backgrounds especially

It almost looks like a large semi-transparent rectangle affecting brightness/gamma uniformity.

Important, the TV was perfectly fine before the update, no shock or physical damage, the issue appeared immediately after rebooting from the firmware update

I already tried:

• unplugging TV
• holding power button
• rebooting
• different inputs

Has anyone experienced something similar on LG OLEDs or Flex models after firmware updates?

Could this be:

• TCON issue?
• compensation cycle corruption?
• firmware bug?

Thanks a lot.
