I think CRTs let your brain do some antialiasing so free details. I have some old 600mb divx rips that still look pretty damn good when viewed on a CRT.

I just had this idea and I cant be the only one though, what about just a slightly blurry physical glass/plastic overlay?

The article points out that LCDs have more lag, but then it states this:

> And if there is scaling involved, there is probably going to be some lag

The lag that's introduced by a scaler is trivial, and measured in microseconds...

In the Super Smash Bros. Melee competitive scene we still use CRTs for in-person tournaments because of the input lag on LCDs. Most original hardware available to play the game doesn't have a digital display output unless you have an early model GameCube and purchase a ~$100 HDMI adapter. Even if you get the hardware setup for modern digital output, most LCD monitors still have poor response times without spending th…

> work by modders to reduce the input lag introduced by the game engine itself Can you link something about this? are people rewriting the core engine of melee?

There's a phenomenon known as Polling Drift where the 2x-per-frame input polling at 120 Hz is mismatched with the NTSC framerate that's 0.1% slower, leading to a variable 0-0.5 frame input lag. This can be patched out.

Additionally, they found that there is an extra frame of buffer hanging around that wasn't necessary so that can be removed.

There might be something else too?

I can't imagine loving a monitor the way I loved my iiyama Vision Master Pro. 1600x1200 at 71Hz driven from a Matrox Millennium (4MB VRAM and no 3D acceleration whatsoever) with soft-edged pixels and no visible grain or mesh. It was by far the best computer-related object I had ever owned. But that would be so impractical now, given its bulk and what else is available.

We actually still have a CRT as our main TV here - a 28" Sony - not for any exciting retro reason but just because we've had it from new and it still works. We have a bigger LCD in another room. We bought that to watch films on, but it was always disappointing for that - it's too clean, it feels as if you're watching the making-of documentary rather than the film itself. So we hardly ever use it and mostly stick with the CRT. It's satisfying to watch, but part of me hopes it'll stop working so we can get the space in the corner back.

I would love to see modern CRTs but we have to be honest with ourselves about the negative environmental side with their lead components. Perhaps we could build a more environmentally friendly CRT with our processes nowadays.

Earlier quoted context omitted.

I never could reconcile the "variable geometry pixels" with my meagre understanding that they all had a matrix / mesh / mask at front, I think for separating individual colour pixels... Didn't they? Edit : here it is - shadow mask and trinitron. These feel like extremely fixed, physical native resolution? https://en.wikipedia.org/wiki/Shadow_mask

So TechnologyConnections made two Vids about that very topic https://www.youtube.com/watch?v=dX649lnKAU0 https://www.youtube.com/watch?v=Ea6tw-gulnQ It's...complicated.

That sounds really similar to subpixel rendering as used in AMOLED displays and their diamond/pentile subpixel arrangements.

I found a demo online illustrating this

The biggest advantage is that CRTs can have variable geometry pixels which match a lot of older resolutions and aspect ratios. While it's a lot easier to deal with non-square pixels on higher resolution displays (i.e. 1600x1200 can properly emulate a 1.2:1 rectangular pixel of a 320x200 display) CRTs still have effectively infinitely variable shaped pixels.

A subpixel on an LCD can only have a single brightness value across its whole area. The dots or stripes on an CRT have no such restriction, they are effectively little monochromatic pictures themselves.

Don't think of those dots as fundamental elements of the image, the CRT doesn't address them and doesn't care about their shape. They are really just a color filter on top of the three greyscale images projected by the electron gun. The shadow mask ensures that each of those three electron streams land on the right color.

See the TechnologyConnections video for more details.

I can't think of anything else than some arcade games requiring the lowest possible latency. People are okay with 50 ping games so 2 ms really doesn't matter to most players.

Tech skill by good players in smash is pretty incredible. Online is a noticably different game than in person from the minimal online lag.

It is simply adding a tiny bit of blur to the entire image.

I don't think it's that simple. Old videogames look really ass on modern displays, even with ostensibly remastered releases that should be doing that tiny bit of blurring.
