What you actually notice sitting on a couch
OLED contrast is the reason people choose these sets, and it does not change much between two consecutive generations. What changes is processing, motion handling and the gaming feature set, which matter more to some buyers than others.
In a bright room, neither OLED reaches the peak brightness of a good mini-LED set. In a dark room, both do what OLED does best.
Buying a generation behind
A previous-generation OLED is one of the better value plays in television, because the panel technology is the same and the discount is usually real. The risk is availability: once a generation is gone, it is gone.
If the price gap is small, buy the newer set. If it is large, the older one is not a compromise on the thing that matters most.

Frequently asked questions
Does the LG C4 support 144Hz gaming?
Yes, the LG C4 supports a 144Hz refresh rate, which is particularly beneficial for PC gamers using high-end graphics cards. Consoles are generally capped at 120Hz, but the TV will handle that input perfectly.
How many HDMI 2.1 ports does the LG C4 have?
The LG C4 is equipped with four HDMI 2.1 ports. This allows you to connect multiple high-bandwidth devices, such as a PS5, Xbox Series X, and a high-end PC, simultaneously.
Is the LG C4 suitable for bright rooms?
While the C4 is brighter than previous OLED models, it is still best suited for rooms where you can control the lighting. In extremely bright rooms with direct sunlight, a Mini-LED TV may provide better visibility.
Is it good for gaming?
Yes, it supports 4K at 120Hz, VRR, and ALLM with low input lag, making it a strong choice for console gamers.
How bright is it?
Peak brightness trails the best mini-LED sets, so it's less ideal for very bright, sunlit rooms.
Is burn-in a risk?
OLED panels can develop burn-in with static content over time, so heavy news or sports viewing with fixed logos is a concern.
