Your hundreds of scanning lines and poor clarity are antique retro. My TVs are large 4k ultra high definition flat LCD screen.
Stores are now showing 4k with Ultra Dynamic Range (LEDs) that produce a wide range from black to very bright..

 

The only RGB video amplifier IC made and sold today for an old CRT display is soldered to its bottom connection bumps in an oven.

Well, that's still just a picture though, you'd have to see it personally to know how exactly it gets. I'm afraid, but your comparison in this context is wrong. Even the most modern OLEDs are no better than old CRTs when it comes to retrogaming in SD resolution, not to mention their contrast ratio is kinda big, but when it comes to 4k/8k video, yes, you're right.
Also there's no poor clarity there anyway, those tubes were hella brighter than modern TV LED bars, specially the Tubes from Sony because their technology was more advanced. Just because a technology is old, doesn't mean it's worse or even useless in certain scenarios. Also I'm not an idiot and I don't live in a cave in order to not be aware of Flat Panels being a thing today, I not even know why you've talked about 4k TVs as if I didn't know anything about that, specially when we already have 8K Ultra HD TVs. lol
But anyway, I wouldn't be insisting on building an amplifier if it wasn't worth it.
This is for a hobby, because I like old games, this isn't for watching Woke Netflix movies in 8k, but thanks anyway, I'll see if I can find a proper analog IC amplifier for RGB signal.

I never asked you to teach anything. All I'm asking you to do is make a selection based on your own criteria about what is and is not an acceptable compromise. It seems like that is actually your job.

Ikr.

 

Not to put too fine a point on it, toward the end, Mitsubishi sold the Diamondtron which was their version of the Trinitron. In at least one case, they prevailed over Sony.

This one?




It looks great, I guess this can't be found anywhere in my area.
This made me remember that there was another consumer TV brand that could compete with Sony, but I can't recall which, they have a really big black 4:3 TV, perhaps it was Mitsubishi too.

 

It is difficult enough to identify a CRT brand in real life, let alone in a photograph : -)

The Diamondtron (or at least the ones they showed me) were very sharp, had good uniformity and small beam landing errors. It is too bad that they didn't get around to making the deal with Sony until just a few short years before the color CRT market evaporated.

Do you think someday in the near future the CRT market might be revived with a better technology? By better I mean something lighter. People these days have no idea of what those screens were capable of.

 

No. I fought that battle and it was lost for good. Flat panel displays (and active matrix LCD in particular) won and for good reasons. It is ok, I enjoy retirement : -)

Well I quite see things differently, flat panels for high resolution, tubes for SD resolution, I believe both could coexist just fine, I don't see why people should chose either one or the other. They could have just left tubes for hobbyists like me, I'd pay my ass out for a brand new Panasonic CRT consumer TV manufactured in this current day and age.

Cathode rat tubes were very good and kept getting better until they were leapfrogged by flat panels. I remember being led into a room at a Sony office to see a 60" diagonal CRT display. It was beautiful but as Joe Morikawa explained, the absolute limitation to screen size was the width of the doorways in a building. So far, with flat panels that is not an issue. The LCD I use on my desk at home is larger than the US $4,000 CRT display I used in my last home and has similar resollution, but cost only US $125. Think about it.

One other little bit that Joe Morikawa at Sony once told me was "If you want to have a good idea of what a CRT costs to produce it, just weight it. Most of the cost is in materials. Display CRTs will not come back.

Well what I mean is a new technology from CRTs, an improvement... Something that could be lighter and yet have the same or better results. If my memory won't fail me, computer CRTs were much more advanced than consumer TVs back in the day, they were like that improvement that I'm talking about.

Accelerated electron display devices are not coming back.

I've spent a lot of time over the years creating modern LCD replacement interfaces for specialized CRT touch screens using every primitive display analog format possible. Good riddance.

 

Remember when old TVs were black and white? Using old vacuum tube video amplifiers with high output impedances caused the high frequencies (clear details) to be attenuated. Viewers did not care. Then color was added at frequencies (around 3.58MHz in North America) where details should be. Similar to the horrible sound of AM radio compared to good sounding FM or DAB radio.

Yeah, but color CRTs were better than black and white tubes in every aspect, LCDs are far inferiors to CRTs when it comes to picture quality, OLEDs are still inferior in the same aspect. Don't beat me, I'm talking about picture quality (contrast and phospor effect), not to mention that CRTs are better than any moddern thing when it comes to gaming in their respective resolutions, like you don't need anti-aliasing for playing modern games like Forza Horizon in an old PC monitor with HD resolution.

Oh....
