I see it many times, commercials, the suggestion, the lie : "Digital perfection "... "digital quality"
And most people believe, fooling thenselves.
I phone call the signed sat TV consumer assistence, and complain about the horrible quality, with digital comporession artefact all the way and details vanished, and all the blur, blurry images, and they just say : "Sr, it's digital quality, it's perfect". "You must be watching a very olf film that was already bad".
If a techncian is on home, he offends my intelligende, when I spot HD 1080p channels looking worse than DVD, and he tells me : "That's because it's not 4K."
People accept digital video artefacts in shadows, popping as a herll, accept loss of texture due high compression rates, accept banding effect artefacts where should be a natural gradient like in a sunset scene, and accept it became 4 times whorse if it's during a fade out.
What about 1080p HDTV.. they said it have a resolution area more then 4 times greater than a DVD (480p), but in reality if we would create a mosaic, filling the 1080p screen with 4 DVD videos, and then cut one and watch comprared to the real DVD, the image would have lost most of details and textures. Yes, the compression used in most TV broadcast it's so ba that would do that. People watxh in TVs no large enough or watcxh too far away, to notice that the 1080p broadcast it's very bad, specially in some countries like mine.
What about 4K films... Again, TV screen not large enough and people sit far away, don't notice 4K details to realise most editions on UHD blu ray it's just interpolation of 2K files, since most movies is finished in 2K resolution. And if LCD was larger, like double, you would need double distance from screen to avoid much distortions of light distribution along screen area.
So, if people are so fooled by lies, producers, TVs, compression rates, and pay channels push crap quality to people, they will be even more about 4K and 8K, cause will have no way to measure, to notice it's not a true claimed resolution.
Take a VHS and record a VHS tape in SP speed, from a prime DVD edition. You will have a nice video for a VHS resoltuion limitations (352×240 pixels), if watch in a CRT flat screen. Now take a 4K video, and create a create a mosaic in such way to fill the 4K frame with hundred of VHS images. Encode it the best you can, then cut one piece of the mosaic and watch in a CRT TV, comparing to the first VHS used in beggining.
Encoders used in HDTV and 4k creates a lot of loss of textures during motion, even soft low motion. These loss is, proportional measures, higher than the percentage of loss DVD encoders created. I see all the time on TV, any motion leading to blur all fine tectures.
So digital home video technology it's far, ver far away from perfection !!!!!!!!
Now lets put the encoders and decoder and broadcast by side, and focus to the screen devices most used today. LCD TVS and LED (just LED backlight on LCD scrren) TVs.
-All LCD TV looks bad, horrible for me at least. All have trash view angle, despite some manufacturers state 170 degree degree, since with even 15 or 10 degree I notice difference in brightness and uneval light along screen area.
-|Even direct straight to the screen I notice the center is brlighter than the edges, even on IPS LCD screen.
-LCD have contrast standart diferent from CRTs, making images fadded, murky, unless you increase contrast adjust a lot, creating annoying clipped whites and crushed shadows. It's similar to the times of PC DVD kit using Power DVD in a computer with CRT monitor, that always looked worse (faded), in terms of contrast, than the best CRT TVs.
-The problem with refreshing rates make horizontal motion softer, even if the video was originally sharp. This is easily noticeable in some tablets, when with pull and push text, upper and dow, and the letters got blured.
-The response time usually make it bad for games. The LCDs with better response time are usually the worst for view angles.
-4K LCD TVs needs to watch close to see true 4K details, if the video is trull4K and not interpolation from 2K source (as most 4K discs are) or less. If you sit close enough to see the 4K details you will face distortion in light distribuion along screen, in LCD TVs, even for TVs with IPS screen. So, for 8K, it's ridiculous to consider...
-HDR TV. These TVs are almost a lie. First the non HDR signals looks like all LCD TVs, poor in dynamic range showing clipped and crushed tones, worse than CRT. And the signals in HDR just look as a expanded dynamix range photo treated in photoshop, and still ahve some clipping in highlightes.
-Plasma TVs create burn in effect, so it's not a good idea for use as monitor or to watch any film with black bars.
-OLED TV cost twice more, have a 50% lifespam compared to LCD, so it's like 4 times more expansive for long term. It also have bur in effect and have lower luminous power.
There is even some movie theater using digital systems that have images artefacts of video compression.. You paid a absurd price for tickets, pay 3 times more for pop corn than in any other place, to watch video compression artefacts in some situations.
That it folks. I don't approve digital technology to be called perfect or great. It's far from it. To me image quality only got worse in my country for TV broadcast, for contrast, gradients, motion scenes... I almost don't watch TV anymore.
