Best praise vs top criticism for Samsung Odyssey OLED G8
Best Praise
+1 pts“Samsung oled g8. Refurbished for 500 bucks. Best deal in the world of monitors. QD Oled 3440 x 1440p 175hz with hdr 400 true black”
r/Monitors
ViewTop Criticism
+6 pts“It is well known that the 34-inch Ultrawide OLED monitors in the market suffer from text clarity issue ([RTings review](https://www.rtings.com/monitor/reviews/samsung/odyssey-oled-g8-g85sb-s34bg85#test_4264)) due to a different sub-pixel layout. 32inch 4K ones are much better it seems, as it has higher pixel density and they changed sub-pixel layout. But otherwise, "the more contrast ratio, the better. The deeper blacks, the better. The brighter, the better." is true. Unnatural colors is a different story from contrast ratio, OLEDs can be color inaccurate just like any other displays.”
