If you're prioritizing picture quality and performance in dark rooms, the LG B3 OLED is superior, with better color accuracy and viewing angles. It's also better for gaming due to its higher refresh rate. However, the Samsung CU8000 LCD is more affordable and might suffice if you're on a budget and mostly watch in a bright room where its lower contrast won't be as noticeable. Keep in mind that OLEDs can suffer from permanent burn-in with static images, while LCDs do not have this issue. Give Feedback
