Hello.

In the past days I have experienced a issue which I dont know how to fix so hopefully maybe someone here can help me out.

It started with my screen flickering (its more like switching between "live picture" and black screen), it happened while gaming and also while just surfing, but it was only flickering and it happened once a day and after that it was good for hours. The flickering lasts just for a few seconds before the screen goes black.
Lately it have gotten worse, now the flickering starts and turns into completely black screen. I still have audio and the power button on the monitor is still lit. There are a few ways I can "bring it back to life" which are turning off and on my PC or factory reset the monitor. Lately i figured out that turning off the PC works the best. Currently it happens quite frequently, about one time every half hour to a hour.

Here are the things i have tried so far:

- Changing cable from monitor to PC (Displayport also HDMI)
- Factory reset the monitor
- Tried different outputs both on PC and monitor (Including HDMI on the motherboard)
- Deep cleaned my PC tower and also re-socketed the GPU
- Checked my drivers for GPU and monitor, also windows
- Tried to disable Multi-Plane overlay

None of these above have fixed the issue.

My PC and monitor specs:

CPU: Intel i7-10700K
Motherboard: Asus ROG Strix Z-490F
RAM: HyperX Fury DDR4 32GB
SSD/HDD: Intel 660p 1TB
GPU: GeForce RTX 4070 TI Gaming X Trio 12GB
PSU: Corsair RM850 x V3 850W
Chassis: Svive Halo S650 Midi tower
OS: win10
Display: LG 45GR95QE - 45" UltraGear OLED Gaming monitor QHD 0.03ms 240Hz with G-Sync Compatibilty

NOTE: I bought the PSU,GPU and the monitor for a bit over a year ago and this is the first time I experience any issues relating to the GPU or monitor. I have also contacted LG support regarding the monitor but I didnt get so far with their help. So I just want to make sure I know which component is at fault here before I trigger the warranty or maybe solving the problem without returning any of them.

Thank you in advance for taking your time trying to help me :)

Can you borrow a monitor in order to eliminate it as the problem.
