Quick hardware-focused checks that aren't in the replies so far. As and have covered the software side, the following will help decide whether the LG panel itself needs repair.

Press the monitor's front/menu buttons to bring up the on‑screen menu. If the OSD appears clearly, the panel electronics and backlight are getting power and the fault is elsewhere in the signal path. If the OSD is absent or very dim, the problem is likely inside the monitor (backlight, power board or panel).

Do the flashlight test in a dark room: while the machine is on, shine a strong torch closely across the screen and look for a very faint desktop image. A faint image means the LCD is still rendering pixels but the backlight (or its power/inverter circuit) is dead. No faint image plus no OSD points to a deeper panel or power-supply failure.

Listen and look for physical failure signs when powering the unit: unusual clicking, whining, heat, burnt smell, or bulging/leaking electrolytic capacitors on the monitor's power board. Many older LCDs fail because of failed capacitors; replacing them is a common repair but involves opening the case and high-voltage risk.

If any of the hardware checks indicate a monitor fault, contact a qualified technician or LG support (or compare repair cost vs replacement). If the monitor hardware appears healthy after these tests, proceed with the software/signal troubleshooting suggested earlier by and . For , start with the OSD and flashlight tests to narrow the next steps.

first step to troubleshoot is roll back the driver and or unistall update...maybe not...other things to try can be display settings and switching plugs etc...

Try to boot windows from safe mode and see if the display show up or not. Mostly the problem lies within windows update and drivers.
