Which to get​

Looking to upgrade my TV and I'm torn between the LG 55UM7300PUA and the SAMSUNG QN77S95DAFXZA.

The LG is a solid option with 4K HDR and smart features, which sounds great for streaming. But I've heard mixed things about its picture quality, especially in darker scenes. The sound quality is decent but might not blow you away. I’m curious about the system performance as well—does it lag with apps?

On the flip side, the Samsung boasts OLED tech, which is said to provide stunning picture quality with excellent contrast, even in tricky lighting. The Motion Xcelerator feature is a big plus for gamers, but I wonder if that’s overkill if I’m just watching movies and shows. Also, what about the sound? OLEDs can sometimes skimp on that front.

What are the potential downsides of each? Which one should I go for if I’m prioritizing picture and sound quality? Would love to hear your thoughts!
