Greetings.

I replaced my Samsung QLED 49" with LG G3 OLED 55". The performance is way better now. Refresh rate 120Hz, VRR, G-Sync etc. The old QLED did not have any of that. However in game image quality is poor, even desktop looks different. The clarity is not there anymore. The image in the game, especially in the flight deck, is not as clear as it was on my QLED. I have spent a week tweaking it but the image is not as clear as before, it is a bit blurry now. I am curious if this is something to do with a larger screen (55"), or this is how OLED TV works if I use it as PC monitor. I am wondering if I should either get 50 or 55" Samsung QLED instead. I cannot figure out what is causing this image quality degradation. 

Thanks for looking. 

I would try this first

 

I have tried all that. It is still a bit blurry. I connected my Samsung and I see the difference right away.
