modern tech is better or is it?

LOL. That's a VERY simplistic broad brush. Nope, it's utter SHITE, and for a few reasons, the most annoying of which is the perpetual re-hashing of something (re-inventing the wheel continually) and it being marketed as "Ground-breaking" and "Game-changing" <CRINGE>

Marketing bollocks is what makes us PERCEIVE all this crap as "better". I'd HAPPILY take the 70s or 80s, and barely ANY of this tech, but with the upside of more compassion, humanity, more community, people ACTUALLY VISITING AND TALKING AND LISTENING... and you can shove all this flimsy plastic "advanced" shite into landfill.

It's a load of old horse shit.

Having a bad day today?


As someone who has done professional 3D graphics and graphic design, I'll gladly take today's display tech over CRT.
As stated before, better geometry, pixel perfect, light weight, not taking up half my desk, and better colour accuracy and gamut make for a happier me.
My laptop has a 100% Adobe Gamut 4K panel and my external monitor is 100% sRGB. Both work great.
I just wish the external panel would get around to dying so I could upgrade to a 100% Adobe gamut screen there too.
Alas, I didn't buy cheap crap (it's an Eizo monitor) so I'll have to endure a good screen instead of a great screen... :D


Having said that, you can pry my collection of small and miniature sized CRT's from my cold dead fingers.....
CRT's are just cool to me somehow, LCD panels just lack a certain charm.

This is all kind of beside the point anyway. The video (which it seems most people didn't watch) is covering a specific and apparently very common failure mode of that particular monitor. It's not that it's a bad looking display, or that high resolution LCDs are all junk, but that particular one frequently fails not long after the warranty is up and the repair is difficult and fiddly.

While I agree that OLED is on another level of awesomeness, I think only the very, very best CRTs actually exceed a decent LCD of today. We like to imagine that CRTs had perfect contrast, but they didn’t: there was some loss due to phosphor persistence, but above all, the phosphors weren’t black when off, but light gray. Most CRTs used some kind of gray contrast filter on the tube face to improve this, at the cost of reduced brightness. And the drive electronics often created a non-black background where actual black should be.

Where CRTs do shine, IMHO, is viewing angle. I hate the color shifts that happen with LCD and to a lesser extent with OLED. Plasma (what I still have in my living room) is almost as good as CRT in this regard.)

+1 for plasma here. Still using a 2007 model Panasonic, it’s not even 720p, and it’s SO clear and bright, it’s not even something I care about. I’m more interested in what I’m watching than it’s geometry.

Modern LCDs have gotten pretty good with viewing angle, even TN.  My Samsung panels have perfect (no colour distortion) viewing angle in the horizontal plane, and only very slight distortion in the vertical plane.  I've never seen an OLED show colour shift from viewing angle though?

The other issue with CRT contrast is internal tube blooming, so even if you managed to adjust the drive strength of the beam down to zero for zero input, a starry night would light up the back of the tube very visibly.  This effect is broadly similar to the LCD blooming effect that region-dimmed LED backlit panels exhibit.

In terms of reliability anecdotes:  I've got a 14 year old (2008) full-HD LCD panel with CCFL backlights I use as a spare monitor.  It had, from the very start of its life, cold solder joints on the IEC connector, and was found in a skip.  But I fixed those and it's been fine ever since.   The bathtub curve definitely applies for newer electronics too.

+1 for plasma, hanging on to my 2012 Panansonic FHD panel as the living-room TV, though it will be soon be replaced with an OLED.
