Re: LPD: Laser Phosphor Display - Successor to CRT?

And fast camera pans like those that used to be done during the CRT days before they slowed down camera panning to accomodate slow-motion-blurry HDTVs when they first came out. Huh, I never considered that. I noticed how the change in aspect ratio from 4:3 to 16:9 impacted camerawork hugely(and in ...

Re: LPD: Laser Phosphor Display - Successor to CRT?

Deliciously fast. But we're still limited via very low pixel refresh rate, but it's actually easier than expected to get kilohertz refresh rates via parllelized scanout logic on MicroLED modules. For example, JumboTron modules (the 32x32 or 64x64 RGB LED metrixes that you can buy off Alibaba or ALI...

Re: 60Hz --> 120Hz realtime dedicated hardware converter or board?

Does your portable monitor have Thunderbolt 3 connections?
This might be a ghetto solution but an External GPU might help.

Re: LPD: Laser Phosphor Display - Successor to CRT?

MiniLED and OLED can be very fast. From what I've read from one of the earliest articles MicroLEDs have sub-nanosecond switching time. That's picosecond response time. From what I remember reading somewhere CRT's have picosecond rise and fall though I'm not exactly sure. It was found that the turn-...

Re: LPD: Laser Phosphor Display - Successor to CRT?

MicroLED does not seem to have a cost-effective method of production (at least for consumer format displays), and OLED, while now being produced, is still quite vulnerable to burn-in. The brighter the pixels are run, the faster they burn-in, and to have a line-by-line scan similar to CRT would requ...

Re: LPD: Laser Phosphor Display - Successor to CRT?

Everyone has preferences on their preferred artifacts -- witness CRT and plasma users holding onto displays. Displays are inherently pick-your-poison. Dislike ghosting/coronas? Dislike flicker? Dislike display motion blur? Dislike phosphor trails? Etc. Some laser phosphor projectors have its place,...

Re: LPD: Laser Phosphor Display - Successor to CRT?

Heh, I've known about this tech for years now. Nobody wants to use Phosphor in their displays anymore because they don't want phosphor trails. I don't see why this tech could not be scaled down to make enthusiast gaming displays. The Sony MP-CL1 projector fits in a pocket and projects 1920x720 @ 60H...

Re: Early 20th century videos reprocessed into HFR

AI that can do that will need to be hundreds or thousands of times more advanced, but work is already in progress to do that type of stuff. Even too, it would decouple the camera, allowing you choice of movement, like walking off the train, or sitting down/standing up inside the train, or looking a...

Re: RetroArch - Variable BFI Mod for 180Hz/240Hz/Etc

But emulator games are low resolutions, like 320x200 rather than 2000 pixels wide, so low MPRT is unimportant in most emulator games. The point is that low MPRT is more important at higher resolutions than at lower resolutions. Technically arcade games are generally like 384x224 or something like t...

Re: RetroArch - Variable BFI Mod for 180Hz/240Hz/Etc

I knew about that 2 million nit thing. I keep up with MLED info overall. It's mostly being considered for AR and Mobile Screens for obvious reasons but I do hope it happens in consumer screens in the future because so much content out there is low framerate so having that head room would be helpful ...
