Has anyone here used a 55" U8N and compared it against the 55" U8K side by side? I have heard both 55" models are almost identical in terms of brightness but I would think the U8N would look better since the U8N has Dynamic Color enhancer.

The best way to compare side by side is on a GPU that has 2 HDMI ports putting it on duplicate monitor mode but only some GPU's have 2 HDMI 2.1 ports. I have a White AsRock Taichi 7900XTX and I might buy a Sapphire Nitro 7900XTX which has 2 HDMI 2.1 ports just to compare both these tv's then return the GPU.

I use TV's mostly for computer use on my gaming computer, PC gaming and 1 console game currently. I don't watch TV shows and movies often but when I do in the future I will do it more often on a new tech TV that I will buy in Jan 2026, probably a RGB OLED, NANOLED, QDEL or even a MicroLED , 2026 will be a big jump for TV technology.

Likely 2026 , MaxOLED (Samsung) , NANOLED, RGB OLED (TCL), maybe QDEL

2027: Smaller 55-65" MicroLED TV's.
