Last year's flagships claimed 3000 nits peak brightness, and they could only achieve half of that claim. It's all marketing BS and these will probably hit 1800-2000 nits and that's for a small window, peak full-screen brightness is 400 nits give or take a few nits
The Philips OLED+950 is another flagship television that is equipped with LG's brand-new tandem OLED panel, which allows the TV to achieve an enormous peak HDR brightness of 3,700 nits and better color reproduction than traditional OLED televisions.
