Why is HD 1080p? | Nostalgia Nerd

To be fair HD is 720P, FHD is 1080p, 4k is UHD and then we kinda gave up as 8k and 16k have no names that I've heard.

Wut? So's 720p...

most ppl play 4:3 720p

the DVD standards were 480i 30fps and 576i 25fps so 720p is 480x1.5 and 576x1.25. THAT'S WHY 720p. Since 720 isn't much larger than 576, 1080p was devised as the first commonly divisible number over 1000 pixels high. THAT'S WHY 1080p. There. Saved you 20 minutes of barking up the wrong tree.

Pal has 50 FPS, just every frame is an interlace. God. You know NOTHING

The FPS was not reduced to 29.97 to carry the colour signal. It was reduced to 29.97*2 to prevent a frequency beat between colour carrier and sound subcarrier.

I grew up with 720p being HD and I can never not think of it as such

Actually hd is 720p your thinking of fhd which is 1080p

Thats wrong lol, HD is 720p and FHD is 1080p

It's SD ED HD UHD 4K 6K 8K 16K

Both 720p and 1080p are HD.

I have from left to right
2560x1440 43' and 900x1440 24'. The TV is frameless design and the monitor has 1cm. Floating windows from one to another is perfect. Also with the monitor in portrait mode is the same height with the TV.

I still have my Amiga... at the time great graphics.... compared to my nivida system... not so much lol. But the Amiga is 35 years old

lol show numbers but don't explain the abbr s in the video... dis

Clearest explanation of the convergence of display resolution I've seen, thanks!

Nice hidden red dwarf reference! lol

Fantastic technology but rubbish programs.

Tv seems to have extreme diminishing returns after 720. 1080 is a slight noticeable difference in picture but all this 4k stuff just looks more vibrant, the picture change isn't noticeable at all to me

Composite standard here was drafted because of tape. That kept us from developing something like a scart carrier. In other regions technology that could sends signals directly to the electron guns was developed thus the invention of Scart in Europe and JP21 in Japan. In the US and Canada makers continued to mimic the tv broadcast standard until the invention of the dvd where for the first time here would could get a clear picture from our home media via a component connection.

HD is 720p, FullHD is 1080p

Yet here I sit in 2024 with a HD 16x9 65 inch panel tv watching movies where nearly half the screen is taken up by top and bottom black bars. Have we really progressed that far?

64K VS 64-bit

The 16:9 ratio was devised by Leonardo da Vinci which he called the Golden Ratio which he used for landscape pictures, to the human eye is is a more natural ratio than 4:3 as humans have stereoscopic vision. Television started off with 4:3 ratio simply as a baseline it was always envisioned that when the technology was available that 16:9 would be the de facto standard world wide. I prefer a tablet to be 4:3 as it is a maid of all work but for entertainment the composition of shows & modern films look better on a 16:9 screen this is of course my personal preference.

4k handily can show both 1080p with pixel doubling and also show 720p content with pixel tripling. I think postprocessing on edge smoothing is still done but at least there's much less interpolation.

720 pixels per active line for SD keeps being repeated, but sadly this is incorrect. It is true that there are 720 pixels per line, but in PAL/SECAM that equates to 702 active pixels per line. The remaining 18 pixels are distributed, theoretically, 9 pixels on the left and 9 pixels on the right of each line, but due to inaccuracies of analogue video timing they often contain some video data. Just look at proper 720x576 versions BBC's Testcard F or W - the chevrons on the left and right point to a point 9 pixels in from the edge.

I'm very sad. what about PAL M

I STILL FIRMLY BELIEVE THAT A PORTABLE 20 inch CRT SCREEN UNDER 5 quilos is POSSIBLE, WHILE HAVING 4k and 120hz resolution and speed

Meanwhile at sony 8K 120 means 1080 60

i actually loved 16x10 ratio

just add some data
2k = 1440 = 720 * 2
4k = 2160 = 1080 * 2
8k = 4320 = 480 * 9 = 720 * 6 && 1080 * 4

... pal 576i is still not join the integer group until 32k ... but 6.67% horizontal black bar on 8k is not that bad

You are just wrong without watching the video. 1080p was never called HD. 1080p is called: Full HD. 720p is called HD.

what the hell is with the subtitles having a mind of their own

Is that intro stock footage Ai generated? Gross

bad start for the title... 720p is HD, 1080p is FHD.

I bet that 38" tv back then would of been the dogs bollocks, id like to have one today.

My CRT 4:3 monitor was 1600 by 1200 and than my CRT broke so I found a flat panel 4:3 that could display 1600 by 1200.

Showing tv sets with snow and noise to explain a tv standard is very lazy and get me lost. Goodbye

Wow, you've knocked it out of the park with the footage - you've always had the dialog down pat though.

What abt 1440p QHD?

In Finland we are just about to even get Antenna TV with all the channels to Full HD next year. There has been some Full HD channels already some years in there, but still most are SD. Next year SD will be gone for good luckily at least after the final day of the switch

Love the Red Dwarf reference and NO, I don't want any toast!!!😆

I've been using 1200p for over 20 years now. Get rekt 1080p. 🤣

Because 720p is HD ready

watching this in 144p

I'm an obsessive-compulsive digital artist, and I had never even considered the historical existence of computers that didn't have the ability to depict a single pixel as a single pixel. That would have completely swayed me away from the field. That would've never been able to coincide with my OCD
