And most people were lucky to have a TV. You were lucky to have a HOUSE! We used to live in one room, all hundred and twenty-six of us, no furniture. Half the floor was missing; we were all huddled together in one corner for fear of FALLING!
It’s not as much about resolution as it was about exploiting the quirks of CRT. Artists usually “squished” sprites horizontally (because crt screens would stretch them) and used the now famous “half dot” technique to have more subtle shading than what was actually possible at the pixel level. So if you just display the original sprites with no stretch and no “bleed” between pixels, it doesn’t look as good as it should.
That’s because the graphics were tailored to CRT resolution - which is to say, low/outright bad resolution.
No, it’s because the graphics were tailored to the analog characteristics of CRTs: things like having scanlines instead of pixels and bleed between phosphors. If they were only tailored to low resolution they’d look good on a low resolution LCD, but they don’t.
I admit I’m quibbling, but the whole thread is that, so…
Maybe one’s before the 80s didn’t, but they almost all do after that. Exactly how this worked varied between manufacturers and the display type, but they tended to have some kind of mask that pushes it to a preferred resolution.
CRTs don’t have pixels so the resolution of the signal isn’t that important. It’s about the inherent softness you get from the technology. It’s better than any anti-aliasing we have today.
CRTs do have pixels. The exact mechanism varying between manufacturers and types. If they didn’t, you could run an SVGA signal (800x600 at 60 Hz) directly into any CRT. If you tried this, it would likely damage the tube beyond repair.
I certainly saw aliasing problems on CRTs, though usually computer monitors that had higher resolution and better connection standards. The image being inherently “soft” is related to limited resolution and shitty connections. SCART with RGB connections will bring out all the jagginess. The exact same display running on composite will soften it and make it go away, but at the cost of a lot of other things looking like shit.

Would it, though? I’m skeptical.
If it did, it wouldn’t be because they have “pixels,” though; it would be because overdriving the deflection yoke with higher-frequency signals would generate too much heat for the TV to handle.
Otherwise (if it didn’t overheat), it should “work.” The result might look weird if the modulation of the signal didn’t line up with the apertures in the shadow mask right, but I don’t see any reason why sweeping the beam across faster would damage the phosphors. (Also, I’m not convinced a black & white TV would have any problem at all.)
It will tend to turn the beam on when it’s off to the side, outside the normal range of the screen. X Windows users in the mid 90s had to put in their exact scanline information or else the screen could blow up. That went away with a combination of multiscan monitors and monitors being able to communicate their preferred settings, but those came pretty late in the CRT era.
Edit: in any case, color screens need to have at least bands of red/green/blue phosphor. At a minimum, there will be breaks along either the horizontal or vertical lines, if not both.
When you say “blow up” do you mean the tube would literally explode, it would burn through phosphors, a circuit board would let the magic smoke out, or something else?
I remember configuring mode lines in X. Luckily, I never found out the hard way what happened if you got it wrong.
CRT filters exist now, and with HDR output (or just sending an HDR-enable signal to get tv’s to use the full brightness range) and 4k displays it honestly as good at this point. or better because the only good CRT’s you can get now are pretty small P/BVM and my tv is much bigger than those
There are plenty of upscalers with minimal latency that fix that.
There also isn’t just “CRT” in this space. Professional video monitors give a very different picture than a consumer TV with only the RF converter input.
If one more under 25 retro fan tells me that RF tuners are the “true experience”, I’m going to drink myself to death with Malort.
Edit: please don’t tell me you believe CRTs have zero latency. Because that’s wrong, too.
The weighed a ton, they were limited in size, their resolution was terrible, they sucked down electricity…
Their screen was curved the wrong way until they released flat screen TVs
4:3 resolution meant you lost some of the content from movies or you watched them with black bars
4:3 resolution also means that a lot of good shows will never be watchable in the proper 16:9 format
No, it means 4:3 IS proper format
We had four channels and loved it!

Have you compared NES games on a CRT with the same games on a modern screen?
CRTs just look miles better.
EDIT: OK, it’s ackchually not technically “resolution” per se, I get it. :p

As a pedant, that is impressive work. Fair enough.
CRTs themselve don’t have concept of resolution.

Crts were jagged and blurry. A misconverged pixel isn’t good anti aliasing.

Literally blow up the tube in the worst cases.

Compare a PS5 on a modern day large screen 4k TV vs a CRT of your favorite brand from any year.
If your only use case is playing old consoles, there’s filters for current emulators that fill that need adequately.
