Battle of the OLEDs: LG and Samsung both unveil panels with 4,500 nit brightness claims — but there's a catch

Two models in white tops and black trousers show a 77-inch Samsung 2026 QD-OLED panel TV.

• New panels promise peak brightness of up to 4,500 nits
• Real-world brightness is likely to be significantly lower
• Still a big improvement over existing panels

LG Display and Samsung Display have both had a bright idea: OLED panels that can put out 4,500 nits of peak brightness. That's a really big deal because the two firms provide the panels for pretty much everybody in the industry, so much brighter OLED TVs are on their way. But can you expect to get all those nits from your next TV?
