Eh, just read that "The only slightly negative thing to me was with the local dimming on the brightness locks to max" That kills the monitor for me as I use the aoc q27g3xmn at about 25% brightness and prefer to leave the local dimming on. Setting it to 100% is way too bright in the evening. Shame that they did that.

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

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.
