ViewSonic XG272-2K - Blurbuster's Certified 240hz 1440p OLED display

[tongshadow]

This is the first OLED of its kind to offer adjustable BFI, up to half of the total refresh (240hz).
Adjustable BFI@240hz means it's possible to reach the same Pixel Blur Persistence as the maximum refresh. At 240hz pixel persistence is around 4.2ms, but because OLEDs have perfect response times, this number is 1.5x higher than an equivalent LCD. Therefore, it's visually closer to a 360hz LCD.

BFI refresh starts at 48hz and goes all the way up to 120hz. In practice this means:

60hz with 4.2ms persistence (75% brightness penalty)
60hz with 8.4ms persistence (50% brightness penalty)
120hz with 4.2ms persistence (50% brightness penalty)

Hmm that's not that good of a motion clarity bump, in addition to the brightness penalty. Then add on no simultaneous VRR, pretty mediocre really. I'd just rather play at 240 Hz sample and hold with full brightness and VRR.

This is cool for people who wanted something that can do BFI at refresh rates other than 100 or 120Hz. But there's still those of us who are waiting on actual 240+Hz BFI OLED.

Better than nothing. It also gives us options. Woot!

Yeah I wouldn't give up VRR for BFI. But the BFI in this has a wide range it can be set to compared to most monitors that don't have it or at best have 1 or 2 fixed frame rates. So that's one step closer to simultaneous VRR BFI. Hopefully it's in the works.

props to the chief, dude is awesome, congrats for helping to get this product out!

Well because of how OLED works, you'd need a 480Hz OLED to do that. Since they don't have a backlight to pulse, all they can do is an "on and off" frame thing, which means they need double the framerate of whatever BFI rate you want.

Not entirely. The LG CX was capable of 120Hz BFI despite only being able to do max 120Hz no matter the resolution. You couldn't drop down to 1080p and get 240Hz or anything like that.

Yeah, I wouldn't have the comparison be against LCD, but against the LG CX/C1, with their 300Hz or more equivalent blur reduction thanks to their rolling scan hardware approach. This unit still falls well short of that in this regard.

That said, this ViewSonic XG272-2K is great to see!

(If it allows BFI with HDR engaged anyway. That has become an essential option with the advent of RTX HDR I think. And please give us an option for a glossy screen...)
