It makes sense you’d be able to get a much higher refresh rate on a tube if you reduce the resolution, since you would be reducing the beam’s travel.
Changing the resolution on a CRT normally doesn’t make the picture smaller. There is no native resolution, phosphors are not pixels. My Viewsonic would display 640x480 or 1600x1200 on the whole 21” regardless. You can also watch the video, it’s not using a smaller area.
I believe the limitation is bandwidth, not the electron beam.
There is a limit on the spacing of the colour bands though. If you want colours then you have to hit the spots where the correct phosphors are and this limits the usable resolution.
Yeah I didn’t think it would make the “pixels” smaller, but the beam would need to pulse less often and therefore could travel more. Maybe I’m misunderstanding what they did.
Electron beams scan insanely fast, that isn’t the limiting factor. Getting that much bandwidth across a VGA cable is tough. If you wanted super high refresh rates on old CRTs you’d have to drop the resolution. Same concept.
320 x 120 resolution
I am embarrassed for having read that
“Ancient”. I had one up until 2008.
Edit: I guess when you think about it, someone born then would be entering high school now. Fuck I’m old. It’s weird because all the 2000s just blend together for me, there is nothing defining the decades anymore, like 80s = cocaine and big hair, and 90s = neon and “radicool” stuff.
I loved my 1600x1200 Viewsonic, used it till 2010 or so. The flicker wasn’t ideal, but man the colors were so much more vibrant than shitty LCD screens of the 2000s were capable of. These days, I think Apple’s fancy LCDs with HDR win on all fronts, but it took a while to get here.
Fun overclocking project. I wonder how far can you go with the fastest LCD monitors
Dell is already at 500Hz 1080p
Is it really worth the cost after 144 Hz, though? Are there applications for a higher refresh rate than the human eye can even see?
This guy is pretty exited about it: https://www.youtube.com/watch?v=nqa7QVwfu7s
He says it looks “real”
higher refresh rate than the human eye can even see
There is no fixed limit on refresh rate that we can see, that’s not how seeing works.
For Joe Everyman with a reaction time of 250-300ms it would probably not be worth the additional cost, but for esports players who have a reaction time of half that already it starts to matter more, especially for games that run synchronously on a tick system.
