LG 27EQ850-B Review 2023: OLED 99% DCI-P3


The LG 27EQ850-B is an OLED monitor for professional use for office and media creation. The main benefit of OLED panel is that you get excellent contrast ratio and fast pixel response time. This monitor has 4K UHD resolution and it comes in 27-inch form-factor. It costs whopping $2000 which is very high, and it seems a little bit overpriced.

The color coverage is excellent with 99% DCI-P3 and that results in superb color accuracy for color-critical tasks. It comes with HDR 10 certification and the stand comes with decent adjustability. The only thing this monitor lacks is high peak brightness which is a huge concern.

LG 29WQ600-W

For around $2000, the LG 27EQ850-B is an excellent OLED monitor for professional use. It offers excellent color coverage upto 99% DCI-P3, but the peak brightness is 200-nits, which seems very low for an expensive monitor.

I think it is quite overpriced for what it offers and you will find a lot of better monitor for half the price of this.

Currently, we think it is not worth spending such a premium price on an OLED monitor. You will find a lot of 4K monitors with high peak brightness for the price half than this.
