It's a shame that plasma tech is dead

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, Turbo240, ToastyX Strobelight, etc.

I'm no CRT expert, but I'm pretty sure the CRT resolution increases you're referring to were only possible in a certain context, and when such progressive resolutions were tried at higher refresh rates, you'd run into physically undefeatable issues.

See sources such as:
https://www.quora.com/Could-we-have-mad ... n-Van-Duyn
CRTs could push 3200x2400 but the masks weren't able to resolve it. Monochrome CRT's had theoretically infinite resolution.
There were some CRT Projectors with enough of a high scanrate to push 4K too and those had no masks(since they were not projectors) so they didn't have the mask issue but they were still limited compared to Monochrome.

Yeah but the horizontal frequency and the number of horizontal lines aren't infinite.

Hence why I said "theoretically". Monochrome CRT's were only limited by the scanrate itself afaik.

Regardless, it's safe to say that mass-manufacture, mass-marketable, consumer-level high Hz Ultra HD (let alone HDR-capable) CRT and/or Plasma at an affordable price was and is not viable, hence the development of alternate technologies to meet those ends (with any shortcoming as a direct effect included, of course).

I've heard that BFI on the CX isn't even viable due to the eye straining pulsating excess flicker on whites, plus it's stuck at 80nits.
The former is a deal breaker imo, just like it is for everybody who's purchased ANY LG OLED, including Samsung's latest QD-OLED line up. It's a shame, because LG & Samsung OLED BFI feels like an absolute tease. Showing you what you COULD have in regards to motion persistence & clarity, but it's basically botched due to bothersome flicker.

My S60 plasma doesn't strain my eyes at all, it looks natural. When i move on down to my LG C1, and use BFI i just can't tolerate the flicks. So i'm then back to being stuck with the C1's 300p motion clarity and high persistence blur, plus choppy OLED judder.

My Panasonic S60 PLasma is so much more pleasing to watch when it comes to streaming Movies/TV. Comparing it to base OLED motion, the plasma has far less motion blur(Still average for plasma motion), 700p M clarity, and noticeably less judder for smoother movements. Perfect blacks and higher brightness isn't anything, especially when you're severely compromising 3 areas with motion.

It's not unusable, but 60Hz "High" mode is definitely flickery, and actually only about 60 nits in mixed content (and much lower for full field white), at least when used with an accurate color temperature (a cooler color temp would likely allow a little more brightness to be retained):

Like I said in the above thread, it's nice for retro side-scrollers and not much else in my experience.
