CRT manufacturing is, at a minimum, an order of magnitude more complex. In all likelihood the ability/knowledge to manufacture high quality CRTs has been irrevocably lost and won't be regained unless somebody wants to sink large amounts of cash (hundreds of millions?) into reviving it. In contrast, vinyl never actually went away. retro-fashion CRTs still have some technical advantages (essentially zero lag) and notable differences compared to modern flat panel displays. The appeal to many of these outdated technologies extends beyond "fashion."

CRTs also scaled images very nicely. LCDs et al have had to rely on higher pixel densities to achieve the same results. This is then requires more powerful graphics processors too. So for games, some gamers have turned back to CRTs which means they can run their games at lower screen resolutions but have all the rendering effects enabled. Resulting in a better looking game than they would have gotten from the same computer hardware powering an LCD display. There might have even been a discussion on here about this actually.

  Agreed on all counts! Digital Foundry has done some excellent videos on CRTs for retro and modern gaming. High end CRTs are actually fantastic for modern games, too, especially at 120hz. (Although, good luck finding/affording one...) https://www.youtube.com/results?search_query=digital+foundry+crt https://www.youtube.com/results?search_query=digital+foundry... While purely subjective, many would agree that low-rez pixel art looks much better on a CRT: https://www.reddit.com/r/interestingasfuck/comments/9xg8w3/the_same_pixel_art_on_a_crt_vs_lcd_screen/ https://www.reddit.com/r/interestingasfuck/comments/9xg8w3/t... There might have even been a discussion on here about this actually. There have been a few. Of course, any time an older technology is mentioned on HN, a bunch of uninformed tech bros dismiss it as "fashion" or "hipster" or "nostalgia." In reality, sometimes these old technologies have unique qualities. I have to laugh at the idea of CRTs being "retro-fashion." I've got a half-dozen CRTs in my home and basement and let me tell you, nobody thinks it's cool ha ha ha ha.

  Yes! They’re also better for rhythm games, like Dance Dance Revolution, because you avoid the lag from upscaling.

A CRT it's only a special vacuum tube. And now, there is a small manufacturing of vacuum tubes in China.

  That's only part of it. There's also the phosphor masks, etc. It's not that we literally don't know how to make CRTs any more. But the manufacturing ecosystem is gone: the machines, the tooling, etc. That was the product of 80 years and many billions of dollars of R&D. Making high-quality CRTs requires some pretty specialized propietary gear. We could probably manufacture a 1950s-style black and white TV without too much effort. But it would be a tremendous leap from there to creating e.g. a high-end Triniton monitor capable of doing 1080p@120hz.

  A vacuum tube with 3 balanced heaters, specific and large blown dimensions, a delicate mask inserted, coated with lead, and wrapped in copper coils. You could make one in your garage for sure. /s

Yes, old technologies (video games consoles before HDMI use, VHS) were made to be displayed on CRT and the quality is far worse when seen on recent TV. I recommend the twitter of CRT Pixels if you want examples.

I was using CRT until recently, sadly it broke in a way nobody could fix :( Reasons why I preferred it over flat panel: 1. Zero lag (lag annoys me a lot when I am gaming) 2. Arbitrary resolutions (for example I was running several recent games using a medium-range video card, with graphic options on ULTRA or above, because the games would look gorgeous on CRT with low resolution) 3. Arbitrary resolutions (want to use content for other format than widescreen? It is covered! Content designed for pixels that are not square? It works too!) 4. Stupid high refresh rate if desired (while lowering resolution of course) 5. Stupid high resolution if desired (while lowering refresh rate). 6. Better contrast (one of the reasons I got CRT back was that I got annoyed with flat panel when I tried to play SuperHOT and watch Game of Thrones on the same day, if I avoided SuperHOT becoming a white blob, Game of Thrones became black blob, if I avoided Game of Thrones becoming black blob, superhot became white blob) The last one sadly is only "theoretical" for me because I never had the right equipment and software, but CRT could do HDR images, for example Silicon Graphics for a time was shipping computers for digital art that had a fancy video card that could output 48 bits of colour, that computer came with a ginormous widescreen CRT too... I believe that CRT is the one John Carmack is using in a famous photo. Also I heard before Windows Vista that introduced a lot of DRM-related restrictions on video and sound drivers, you could do a lot of fancy shenanigans with CRTs, seemly intended for engineers and architects, but I never got too much details about it, I never seen it in person and nobody ever described it to me, I only saw people bemoaning it was removed.

I'd love to know more about this if you manage to jog your memory. I'm not sure what you're referring to so that's why I'm interested.

    I remembered the name, it was "Overlay" seemly it allowed you do things like control the RAMDAC directly and skip the CPU, send arbitrary information to the CRT, and other shenanigans. From what I understood the non-official reason for its removal was to prevent people from using it to circunvent HDMI restrictions in a way that would allow them to duplicate movies without using DRM. The official reason was that it caused driver instabilities and thus Microsoft was against its inclusion in the new driver model for Vista. Why it was popular with CAD, I have no idea.

Zero lag is the really important bit. If you're a top-level speedrunner of a retro game, there's just no good alternative yet. When existing CRTs deteriorate beyond repair, that's a big problem. We can replace aging consoles with highly accurate FPGA clones, but we can't replace the displays. The best modern displays still effectively lag behind a CRT by about a frame (~15ms), which really does matter.

  If you're a top-level speedrunner of a retro game, there's just no good alternative yet. I think even the most casual of gamers feel the difference when input/display lag is reduced, even if they don't know why their enjoyment is greater. Similar to how most folks, in a blind test, would prefer a fresh-baked pastry from a skilled baker that uses quality ingredients vs. some kind of shelf-stable junkfood pasty. They would likely not know or care about the fact that one uses high quality grassfed butter and the other uses partially hydrogenated oils and that one uses cane sugar and the other uses corn syrup. But they would enjoy one more than the other, even if they weren't able to articulate why.
