The Quest To Save the World's Largest CRT TV From Destruction (arstechnica.com) 60
A rare Sony KX-45ED1 television, considered the world's largest CRT TV, has been preserved from destruction in Japan, marking a significant moment for gaming history preservation. The 440-pound display was salvaged from an Osaka restaurant days before its scheduled demolition, following a two-week international rescue operation.
Gaming enthusiast Shank Mods, aided by local contacts and industrial shipping experts, secured the functioning 45-inch unit, which originally sold for $40,000 in the late 1980s. The TV, valued by retro gaming enthusiasts for its authentic, lag-free display capabilities, could potentially become a public exhibit pending future funding.

Any tv that also does upscaling and whatever, you can add another frame of latency minimum but its going to be more like 4 frames more because thats how temporal ai upscaling bullshit works
Re: (Score:2)
Indeed, and the delay can be no better than 1.5 frames (average) of latency.
Why? I mean yes, I know that a lot of existing hardware does this because it captures an entire frame and scales it, but in principle, there's no reason you couldn't do a scaler that has only a little over one field of latency (1/60th of a second) — just enough to start capturing the intervening scan lines — or, for that matter, disable scaling entirely, do dumb pixel doubling, and scan the LCD lines in a different order, resulting in zero added latency.
And even without a true native interlaced
Re: (Score:2)
it's about input latency. LCDs by design do digital image processing on every frame which adds a delay between when you press a button or move a joystick and when you see the result on screen.
Overall latency is what actually matters. With a 60hz console running on a CRT there is still the 16ms scanout to actually update phosphors with the full frame.
Native refresh of a modern panel is 240hz (4ms scanout) or more... even if you presume several ms of input latency this is still half of the overall latency of the CRT.

And that is just not true. CRTs do "post-processing", it is just all analog and crappy.
Re: (Score:3)
Analog "post processing" is nothing like "post processing" being referred to. This is why lag on CRTs is measured in single digit nanoseconds. On LCD based screens, it's usually in tens of milliseconds. I.e. hundreds to thousands of times worse. They're not even in the same ballpark. Heck, not in the same game.
Re: (Score:2)
but then you have to wait for the refresh scan, that aint happening in nanoseconds silly boy.
Input lag and refresh rate are two different terms describing different things. By definition lag is the wrong frame displayed during the scan. A CRT will display the frame as soon as it's available.

Re: (Score:2)
Lag and scan rate are two different things. The latter is how long it takes the current frame to be displayed, where as lag is how long it takes the *correct* frame to be displayed. Any lag at all by its nature will result in a frame delay of at least scan rate + 1 for fully synchronous frames.
But frames don't need to be vertically synchronised, you don't need to wait to the end of the frame to start displaying the next one.

What? Lag on a typical CRT is 12-17 milliseconds. More like 35 ms for an actual TV. The phosphors themselves had a response time of several milliseconds.

First of all, no. LCDs inherently require some post processing to display the output, which means that there's no way for them to be "lag free" i.e. have nanosecond grade lag. They're pretty much stuck in a few millisecond range at best. OLEDs are better but still not a match for CRT.
Also CRT displays don't have fixed resolutions the way LCD and LED based displays do. They're analogue.
I used to overclock all my CRT displays back in the day for higher refresh rates for example, and most could push them very high. Though many would give off annoying coil whine when they were close to the limit, not to mention heating issues. Ability to display resolutions was also usually more than the spec, and since they didn't have a native resolution they would display all resolutions equally accurately.

In some respects, such as the processing time of LCDs, you're right. But no, CRTs couldn't display "any" resolution because they were analog. The colors were analog, yes. But driving the screens at higher-than-supported resulted in blurry pictures. There certainly was a limit to their resolution, and that limit was pretty small compared to today's 8K monitors.
Re: (Score:2)
Any resolution, no. But they could generally do "resolution x at n hz, resolution y at m hz, resolution z at o hz" where resolutions would go up and refresh rates go down. Essentially the problem was that speed of scanning was about the same, so you could choose to do less sweeps for lower resolution but more times per second, or more sweeps for higher resolution but less times per second.
This obviously had an upper limit, but that was usually pretty high. Especially for screens at the end of CRT cycle. Big

Unless you were sitting in front of your CRT with the mask and phosphor layers somehow removed and shining the electron beam into your eyeball, yes they absolutely have a native resolution.

That's not-quite-right in a way that's misleading. CRTs have fixed refresh rates, sometimes for the more advanced multisync displays, they are forgiving, and you can drive them at rates that are close enough that the circuitry will sync up for a surprisingly liberal interpretation of, "close enough."
But then in color CRTs, there is the shadow mask, and that most definitely sets a pixel pitch. Look closely enough on a tube that has one of the venerable Sony Trinitron tubes in it, and it looks rather like a

Think about what you just said. Sure, if you wrote a byte to memory at just the right time, then it might end up on the screen pretty fast. Might, if you can actually write a byte that close to it being read, and the video memory isn't double buffered and etc.
Even then, who cares how long it takes a carefully timed pixel to get to the screen? If you missed your write then you've got to wait a whole scan to get another try.
