LG G5 or LG G6: which to choose?
The G6 replaces the G5, LG's brightest OLED. Independent lab measurements show two very similar TVs, but the G6 scores where it matters most: reflections and brightness. Here's our verdict.
- Two high-end OLEDs, perfect blacks and both at 165 Hz
- The G6 : reflections almost halved, brighter, perfect gradients
- The G5 : already exceptional picture and end-of-series price
- Our advice: the G6 for a bright living room, the G5 otherwise
The G6 succeeds the G5, LG's brightest OLED and the favourite of demanding living rooms. As with the C series, we looked at the measurements from the independent laboratory RTINGS, which bought and tested both models. Verdict: two excellent TVs, very close, but the G6 improves where it shows most, in a bright living room.
What doesn't change
Both are high-end OLEDs designed to be wall-mounted: ultra-slim design (about 2.5 cm), VESA 300 x 300 mount, four ports HDMI 2.1, up to 165 Hz, Dolby Vision but no HDR10+, and the system webOS. Same instant response time for gaming, same perfect blacks, and same burn-in risk, judged low with varied use.
What the G6 does better
Far fewer reflections
A lamp or window reflection is almost half as intense on the G6 (about 12% versus 20% on the G5). It's the biggest everyday improvement.
Even more brightness
In real scenes, the G6 goes higher (about 1,090 cd/m² versus 800 in SDR). In HDR, its peaks reach about 3,500 cd/m² on small areas, versus 2,400 for the G5.
Perfect gradients
Skies and plain walls without visible 'banding': 9.8 out of 10 for the G6 versus 8.5 for the G5. It also cleans up low-quality video a little better.
More frugal
About 62 W in typical use versus 80 W for the G5 tested, and a much lower maximum.
Where the G5 holds its own
- Viewing angle : colours stay accurate a little further off-axis.
- The price : late in its run, the G5 costs much less for an already exceptional picture.

RTINGS laboratory measurements on the US versions (updated October 2026). The European versions (OLED55G54LW, OLED55G64LW…) use the same panel and electronics; small differences may still occur from one unit to another.
Our advice
If your TV faces a window or you watch a lot during the day, the G6 really makes a difference thanks to its reduced reflections and brightness. In a rather dimly lit living room, the G5 end-of-line model offers almost the same picture for far less.

Is the G6 worth the price difference?
Yes if your living room is bright: the reduction in reflections is visible every day. In a dimly lit room, the G5 remains an excellent choice for less.
Can you stand the G5 or G6 on a piece of furniture?
They are designed for wall mounting, but an optional stand or compatible table stand is available depending on size. Ask us according to your model.
Does the G6 support HDR10+?
No. Like the G5, it supports Dolby Vision, HDR10 and HLG, but not HDR10+.
