A way to salvage the poor CRT recycling issue - Blu-ray Forum

I heard that with this jumped newer TVs, that CRT TV is going to be recycled into other stuff. And that these lighter TVs would use less energy, and have less toxic byproducts.

Well about a half a year ago I learned that there's only one thing that CRT TV glass can be recycled into: other CRT glass. Deleading the glassis almost impossible.

I think I might have found a good use for CRT TVs. Convert giant Cinema CRTs into gaming size CRTs.

First of all any CRT that's bigger than 16 inches is going to require more than one person to move. And some people say 32-in CRT TVs are too small?

As for the substitutes to CRT TVs, they all fail in one major aspect, display ping time.

Take this little test find an Atari 2600 and look for the game kaboom. Find an ntsc vcr and plug the 2600 RF output into that and the VCRs outputs into the composite input of your modern TV.

The test for a good TV as whether ping time is satisfactory is can you play Kaboom on it as well as you can a CRT TV?

Every TV that is not a CRT TV will fail. The nature of the modern TVs require an input buffer so it could produce the whole frame all at once. And in order to have the whole frame go out at once the whole frame has to pass. As opposed to a CRT which draws it dot by dot by Dot, or in the case of true analog in a continuous line whose points are indicated by certain dots on the programming line.

It seems like modern games have more play then the classics because the modern games have to play into the fact that there's going to be delay.

And obviously most movie watchers would probably not care about whether it comes microseconds late or 100 milliseconds late as long as the movie is synced with the video and the audio, and it doesn't look like Rita r
Repulsa reciting her lines, then everyone is happy....

Except the gamers. I heard the best non-crt technology is TN. And the best of the best has 9 milliseconds delay. Which is about half a 60 Hz frame.

I try to do the ultimate ping test which is getting Michael Larson's score on a computerized version of Press Your Luck. The only way I could do it is with an iMac that was a CRT version of an iMac. And the reason why he does it is because the program could sense when you press the button and what was on the screen at the time. Occasionally I hit a whammy but it rewound it back a couple of milliseconds to before the whammy because it does verification on the flash website.
I never tested the Playstation 3 or the Wii versions on a CRT yet but on my PS3DTV I could never hit it on time.

And I know this two facts which makes 20-in CRT TVs a smart idea. One is that around 16 in when 4x3, it's considered the size where CRTs and future technologies use the same amount of energy. It's just that TVs grow exponentially bigger in energy usage as the screen sizes grow linearly bigger.

also I noticed there's usually a size limit on what's considered a computer monitor. A movie going you could give an 80-inch screen and still some people will ask for larger. But Gamers if you give them too big of a screen their neck will wrench, and would be at a competitive disadvantage.

Hopefully you notice when there's a stadium with a large jumbotron that Gamers compete on local monitors they are close to and small while the raving audiences cheer and scream while watching the performances on jumbotrons.

Most competitive Gamers want a screen that is large enough where they could zoom in on any detail, yet zoom out and see the whole screen at once without having to move their body.

Since Cinema size CRTs are no longer in Vogue, in addition to requiring the hiring of a moving Team every time you want to move it, usually the game himself can handle the CRT at a size comfortable to him or her if the floor was clear along the way. They might need help with steps but that's about it.

considering Cinema size CRTs are rotting doing nothing except polluting landfills, gamer so CRTs are being snapped up on eBay, and there's very little energy usage between gamer size CRTs and gamer size non-crts, why don't we see more gamer size CRT TVs recycled from the cinema sized CRT TVs?

And CRT so the only TVs I could do the light gun accurately. Did you know that the delay of a VCR even though it's tens of microseconds, can throw off the submicrosent timing of a CRT TV. plus Sega approved CRTs can be easily converted to 3D TVs by using the frame alternating method and shutter screen that is synced with the TV.

until there is a solution that could get 1 millisecond a ping or less in a display, CRTs are still going to be in demand and the supply is creeping down. And there's a supply in landfills that are illegal to touch.

These are the facts I heard. I may be wrong with some facts (because I heard them secondhand, so someone has a more definitive source that's different let me know), but assuming all these facts are true, thenbrecycling Cinema CRTs into gamer CRTs would be both environmentally responsible and profitable for whoever does this.

Until we get the unicorn of the submillisecond modern Display, there's going to be a market for these. But once that unicorn comes then we have to think of something else.

I hate to say it, but I think you've been living under a rock.

CRT TVs and monitors have already had their renaissance in the gaming world. What you're posting about has been all the rage for about the last 4-6 years. Virtually every fan of so-called "old school gaming" has already purchased at least one CRT, usually a PVM/BVMs under 22 inches. Then there is another market for standard CRT TVs (20-36"), then another market for the HD 1080i CRT TVs. Not as much of a market for rear-projection CRT displays and very, very few quality CRT front projectors are still available.

The problem is not recycling anymore, the problem is that there just are not that many CRTs still functioning in the world. No warranties. No repair technicians. No replacement parts. It's all DIY, scouring online wanted ads, etc.

Add to that now we have broken through the 300Hz barrier for LCD (TN and IPS) to get closer to the CRT latency. Competitive gamers on PC typically run games well over 300fps in order to not just reduce visual latency, but also improve responsiveness of mouse/keyboard inputs - the overall system latency.

CRT is still awesome in many ways, but with all the new methods (Framemeister, etc.) of getting classic game consoles to look and "feel" right on modern displays, the incredible state of modern emulation, CRT doesn't have much time left.

Some good viewing if you want to learn more:

I have a 34" CRT covered in my garage just sitting, and I don't know what to do with it. The TV felt like it weighed a ton and it took four people to lift and moved it to the garage when I bought my first plasma years ago. There's nothing wrong with it, it's just nobody want it because it's old, so I guess it'll have to stay there until I can get rid of it somehow. I was thinking about putting it on the curb for somebody to take it, but the TV is too darn heavy, and I don't want any old electronics, TVs and such to sit in front of my house because it will be an eyesore.

The gaming crt rage screwed me out of getting some amazing crt's I have been clamoring for due to their massive price hikes (GDM FW-900, and BVM D32's used to be affordable). I'm happy the tech is seeing a renaissance, but sad that it's at the expense of me.
