TCL Class S4 4K LED Smart TV (S4 / S450G) vs LG OLED evo C4 Series (2024)
If you're on a budget, the TCL Class S4 4K LED Smart TV (S4 / S450G) is the way to go, boasting a 60Hz refresh rate. However, if you want the ultimate viewing experience, the LG OLED evo C4 Series (2024) offers a stunning 144Hz refresh rate that’s a game-changer for gaming and fast-paced content. In published testing, the TCL’s native contrast ratio of up to 8000:1 makes it solid for dark rooms, but the 250 nits peak brightness falls short for HDR. On the other hand, LG’s peak brightness of up to 1,000 nits makes HDR content vibrant and lifelike, which is a major plus for movie buffs and gamers alike. Key specs: Refresh: 60 Hz vs 144 Hz and HDMI: 3 ports vs 4 ports.
