Greetings. 

Trying to make a decision if upgrading my current TV will make a difference. 

I currently have Samsung Q80T 50” 4K TV. Overall no problems. I have powerful PC and GPU so overall performance is good, however I see some stuttering. My current TV has 60 Hz refresh rate, no G-Sync etc. 

I tried to enable DX12 and NVIDIA DLSS and I noticed fps went up to from 50 to 110 in FSDT ORD scenery PMDG 737. The performance was great but the only downside is that some areas on the screen looked weird when I move cameras, like small lugs. A friend of mine told me it could be due to my TV refresh rate is 60 but GPU produces much higher. He had same issue and when he upgraded his TV with 120 refresh rate this problem went away. 

Below are two TVs I am considering. I would like to stick with 50” screen. 

LG - 48" Class C3 Series OLED 4K UHD Smart webOS TV

Model:OLED48C3PUA 

50" Class Samsung Neo QLED 4K QN90C

 

Based on reviews OLED is a better option but few things are am concerned about OLED: permanent burn-ins, aggressive ABL. 

LG has 120 Hz refresh rate and G-SYNC, Samsung is 120 Hz as well but no G-SYNC. 

Does G-SYNC really make a noticeable difference? So I am trying to make a decision if such TV upgrade worth the money, if so, which one of these two will be a better option. 

Thanks. 

LG C3, OLED image quality is significantly better than QLED.  If you do any sort of night flying you'll want OLED to get the true blackness.

The days of OLED burn-in concerns are long gone with current technology of OLED panels.

Thanks for the advice. 

I ended up buying LG - 55" Class G3 Series OLED 4K UHD. Replaced my Q80T. Totally different experience. So far so good. 

G-Sync makes a massive difference.  Although I would look for more than just Gsync compatible.  Just posting this in case somebody else hits this thread later.
