It'll happen to you!

The year is 2045. My grandson runs up to me with a handful of black cords
"Poppy, you know computers, right? I need to connect my Jongo 64k display, but it has CFONG-K6 port, and my Pimble box only has a Holoweave port, have you got an adapter?"
Sadly I sift through the strange cords without a shred of recognition. Truly my time on this mortal coil is coming to a wrap
- Don't worry, maybe they misjudged the size of the asteroid and 2032 is it.
  
  Cool, I won't have to update my date formats.
  
  Honestly, that'd be kinda sick. Imagine seeing the wall of fire, coming to cleanse the Earth once again. Hopefully the next ones to inherit it don't fuck it up as bad as we did.

I hope HDMI dies off in favour of DisplayPort. We need fewer proprietary standards in the world.

Kinda already happening with usbc
- USB-C uses the DisplayPort protocol in many cases.
  
  Yeah but in the context of physical connector that doesn't matter, you can really run almost all protocols over almost any connector if you want to (no bitrate guarantees)

Remember DVI?
- Hell, remember dot-matrix printer terminals?
- VGA and DVI honestly were both killed off way too soon. Both will perfectly drive a 1080p 60fps display and honestly the only reason to use HDMI or Displayport with such a display is if that matches your graphics output
  The biggest shame is that DVI didn't take off with its dual monitor features or USB features. Seriously there was a DVI Dual Link with USB spec so you could legitimately use a single cable with screws to prevent accidental disconnects to connect your computer to all of your office peripherals, but instead we had to wait for Thunderbolt to recreate those features but worse and more likely to drop out
  
  DVI -- sure, but if you think 1080p over VGI looks perfect you should probably get your eyes checked.
  
  My dude, VGA is ANALOG it absolutely cannot run a LCD and make it look right, it is for CRTs
- Remember? I still use it for my second monitor. My first interaction with DVI was also on that monitor, probably 10-15 years ago at this point. Going from VGA to DVI-D made everything much clearer and sharper. I keep using this setup because the monitor has a great stand and doesn't take up much space with its 4:3 aspect ratio. 1280x1024 is honestly fine for having voice chat, Spotify, or some documentation open.
  
  Hell yeah. My secondary monitor is a 1080p120 shitty TN panel from 2011. I remember the original stand had a big “3D” logo because remember those NVIDIA shutter glasses?
  Connecting it is a big sturdy DVI-D cable that, come to think of it, is older than my child, my cars, and any of my pets.
- Remember it? I work on PCs with DVI connected monitors every day.
  
  Hell, I still use VGA for my work computer. I have the display port connected to the gaming laptop, and VGA connected to the work CPU. (My monitors are old, and I don't care)
- My monitor is 16 years old (1080p and that's enough for me), I can use dvi or HDMI. The HDMI input is not great when using a computer with that specific model.
  So I've been using DVI for 16 years.
- I ran DVI for quite a while until my friend's BenQ was weirdly green over HDMI and no amount of monitor menu would fix it. So we traded cords and I never went back to DVI. I ran DisplayPort for a while when I got my 2080ti, but for some reason the proprietary Nvidia drivers (I think around v540) on Linux would cause weird diagonal lines across my monitor while on certain colors/windows.
  However, the previous version drivers didn't do this, so I downgraded the driver on Pop!_OS which was easy because it keeps both the newest and previous drivers on hand. I distrohopped to a distro that didn't have an easy way to rollback drivers, so my friend suggested HDMI and it worked.
  I do miss my HDMI to DVI though. I was weirdly attached to that cord, but it'd probably just sit in my big box of computer parts that I may need... someday. I still have my 10+ VGA cords though!
- Yeah it was a weird system just like today's usb-c it could support different things.

I mean, it could... but if you run the math on a 4k vs an 8k monitor, you'll find that for most common monitor and tv sizes, and the distance you're sitting from them...
It basically doesn't actually make any literally perceptible difference.
Human eyes have ... the equivalent of a maximum resolution, a maximum angular resolution.
You'd have to have literally superhuman vision to be able to notice a difference in almost all space scenarios that don't involve you owning a penthouse or mansion, it really only makes sense if you literally have a TV the size of an entire wall of a studio apartment, or use it for like a Tokyo / Times Square style giant building wall advertisement, or completely replace projection theatres with gigantic active screens.
This doesn't have 8k on it, but basically, buying an 8k monitor that you use at a desk is literally completely pointless unless your face is less than a foot away from it, and it only makes sense for like a TV in a living room if said TV is ... like ... 15+ feet wide, 7+ feet tall.
- Yes. This. Resolution is already high enough for everything, expect maybe wearables (i.e. VR goggles).
  HDMI 2.1 can already handle 8k 10-bit color at 60Hz and 2.2 can do 240Hz.
- Commercial digital cinema projectors aren’t even 8K. And movies look sharper then ever. Only 70mm IMAX looks better and that’s equivalent of 8K to 12K but IMAX screens (the real ones not digital LieMAX) are gigantic.
  Also screen technology has advanced faster than the rest of the pipeline. Making a movie in a full 8K pipeline would be way too expensive. It’s only since recent years that studios upgraded to a complete 4K pipeline from camera to final rendered out image including every step in between. And that’s mostly because Netflix forced studios to do so.
  True native non upscaled 8K content won’t be here for a long while.
  
  This is the most "um acktually" of um actualities but...
  For the Apollo 11 documentary that uses only 1969 audio/video they built a custom scanner to digitally scan the 70mm film with the intention that the originals will never need to be touched again at least in their lifetime and its ~16k resolution.
  Granted I don't think you can get that version anywhere? But it exists.
  Super cool doc by the way. Really surreal seeing footage that old at modern film quality. The documentary about the documentary is also really interesting.
- While it is pretty subtle, and colour depth and frame rate are easily way more important, I can easily tell the difference between an 8k and a 4k computer monitor from usual seating position. I mean it's definitely not enough of a difference for me to bother upgrading my 2k monitor 😂, but it's there. Maybe I have above average vision though, dunno though: I've never done an eye test.
  
  Well, i have +1.2 with glasses (which is a lot) and i do not see a difference between FHD (1980) and 4k on a 15" laptop. What i did notice though, background was a space image, the stars got flatter while switching to FHD. My guess is, the Windows driver of Nvidia tweaks Gamma & light, to encourage buying 4k devices, because they needed external GPU back then. The colleague later reported that he switched to FHD, because the laptop got too hot 😅. Well, that was 5 years ago.
- That graph is fascinating, thank you!
  
  I don't think it's correct though.
  The graph suggests that you should be looking at a 65-inch screen from a distance of 120 cm for resolutions above 4k to be worth it. I interpret that as the distance at which the screen-door effect becomes visible, so this seems awfully close actually.
  A 65-inch screen has a width of 144 cm, which gives you a 100 degree angle of vision from the left edge to the right edge of the screen. Divide the approximate horizontal resolution of 4000 pixels by 100 and you get an angular pixel density of 40 PPD (Pixels Per Degree).
  However for the pixel gaps to become too small to be seen or in other words for the screen-door effect to disappear, you need an angular pixel density of 60 PPD. That means you can sit at a more reasonable distance of 220 cm in front of a 65-inch screen for resolutions above 4k to be worth it.
  This is still too close for comfort though, given that the resulting horizontal angle of vision is 66 degrees. The THX cinema standard recommends a horizontal viewing angle of 40 degrees.
  So multiply 40 degrees by 60 pixels per degree to get a horizontal resolution of 2400 pixels. That means the perfect resolution for TVs is actually QHD.
- Btw, https://en.m.wikipedia.org/wiki/Angular_resolution
  And already 4k tv would have to be, what, 2m diagonale, in usual viewing distance of 3m+.
- doesn't this suggest that my 27" monitor I sit a foot away from should just be 480p? that seems a little noticable to me
  
  I think you got this wrong. If you sit 0.3 m away, more than 4k is worth it.
  
  I think you're misreading ' as "
  If it's 27" and 1' away that puts it into the highest resolution category

DVI is the Gen X of video connectors
- Where do my boys Component and S-Video end up?
  
  in my box of cables, for one!
  
  S-Video is second from the left.
  
  With all the rest of the A/V cables, not the computer ones
  
  I remember finding 10 foot combo Toslink S-video cables at Radio Shack for like $5. I bought 3 of them and ripped the S-Video off because the Toslink cable was all I was after. I still think it's better than most other cables for audio.
- My monitors only have DVI and VGA inputs. I've had to get adapters to use them with more modern equipment.
  I've got no reason to replace them. They're perfectly fine monitors. I've had them for over a decade, and I still like them a lot.

nobody noticed dark side of the moon cover on the background
- It's a woke poster. /$

VGA was just analog, it wasn't because the resolutions supported weren't HD.
- 100% right. I know it can handle 1920x1080 @ 60hz and it can handle up to 2048x1536
  
  I remember my buddy getting a whole bunch of viewsonic CRTs from his dad who worked at a professional animation studio. They could do up to 2048×1536 and they looked amazing, but were heavy as fuck for lan parties lol. I loved that monitor though, when i finally 'upgraded' to an lcd screen it felt like a downgrade in alot of ways except desk real estate.
  
  It can handle way more than that can't it? It's analogue, I remember being able to set my crt to 120hz way back in the day.

The meaning of high Res wasn't changed though also VGA was able to output Full HD as well.
- My old 19" CRT monitors could do QXGA [2048x1536] (or maybe even QSXGA [2560x2048], though I think I skipped that setting because it made the text too small in an era before DPI-independent GUIs) through their VGA connections, which is more than "Full HD."
  When I switched to flat-panel displays close to two decades ago it was a downgrade in resolution, which I only made up for less than a year ago when I finally upgraded my 1080p LCDs to 1440p ones.
- But no sound, that was one of the advantages of hdmi over vga
  
  Wait, how is losing my independent speakers and having an audio setup not instantly compatible with my CD player, VCR, and my Victrola an upgrade?

It already happened to them multiple times that's why we are on HDMI 2.2 which can go up to:
7680 × 4320 @ 60FPS
HDMI 1.0 could only reach:
1920 x 1080 @ 60FPS
The only reason it still works is because they keep changing the specifications.
And I think I can confidently say we will never need more than 8K since we are reaching the physical limits of the human eye or at the very least it will never be considered low resolution.
- Maybe, but I could see thunderbolt replacing HDMI and display port over time. It can carry video, audio, data, and power simultaneously, and has more bandwidth for additional information like HDR or 3D.
  
  USB can do that as well, using Displayport alt mode. And it doesn't need Intel's fees.
  Also, 3D. LOL
  
  But can it spy on users for marketing purposes? That's the real question.
  /s
- I can see more than 8k being useful but not really for home use. Except possibly different form factors like VR, not sure on that one either though.
  
  Na, when you go any higher in commercial use you just use multiple cables, HDMI 2.2 can only reach 10ft as it is if you lower the bandwidth it can go farther, I could see a optical video standard for commercial use though.

VGA should have released VGA2.1 that is what all the cool display cables do
- Then a a month later VGA 2.1B. After that VGA 3.0 Fullspeed and 3.0 Highspeed, to make things "less confusing."
  
  Names are uaeful, I use fast Ethernet when connecting a server because it's fast.

I don't think you'll need much more than 8k 144hz. Your eyes just can't see that much. Maybe the connector will eventually get smaller, such as USBC?
- USB-C is already a plug standard for display port over thunderbolt. Apple monitors use this to daisy chain monitors together.
  
  But its DP implemented within USB, vs an actual DP. There's a latency there which might matter for online realtime gaming
- 640k of RAM should be enough for anybody
  
  You think that's a clever analogy but it's not even close.
- I can see a clear difference between 144hz and 240hz, so even that part isn't right
  And I haven't used an 8K monitor, but I'm confident I could see a difference as well
  
  Yeah, frequency might go a bit higher. But I doubt many people could tell the difference between 8k and 16k.

I still use VGA

laughs in bnc
Supposedly 0-4Ghz passband and can carry 500v. No idea what that translates to in terms of resolution/framerate, only that it's A Lot. Biggest downside is that it's analog.
Edit: for comparison, iirc my CRT monitor runs somewhere around 20~30Khz for a max of 1280x1024@75hz. I may be comparing apples to oranges here (I'm still learning about analog connectors, how analog video works, etc), buuuuut that suggests that a bnc connect running at its highest rated output would potentially be able to run some fairly large displays.
- Nah, not only analog.
  SDI - with 24G SDI being the latest standard, able carry up to 24gbps - is alive and well.
