Asus ROG Swift OLED PG32UCDM Review: The Best Gaming Monitor We've Tested
I've worked and gamed on 27-inch 4K 144Hz IPS screens for the past five years - starting with an Acer Nitro XV273K that required two DisplayPort cables to hit a full 4K 144Hz! - so moving to a 32-inch 240Hz QD-OLED like the PG32UCDM immediately felt like a huge step forward. Despite offering the same resolution - and therefore requiring the same level of GPU performance - you're getting a significantly larger image that's still quite sharp at 140PPI, with dramatically better contrast, motion clarity and HDR performance than even modern Fast IPS alternatives.

WOLED vs QD-OLED Monitors - Which Panel Technology is Better?
WOLED stands for White OLED and has been popularized by LG. WOLEDs feature four subpixels: red, green, blue, and white. WOLEDs do away with the individual emitters for the red, green, and blue filters, and rely on a single layer that emits white light. The white subpixel doesn't have a filter, so it lets the white light from the emitter pass through uninterrupted.
