That's a technical topic, to raise one point that anoys me about LCD introduction.
Despite the HDTV and and 4K technologies, I notice a strange thing in terms of image contrast, about of pleasant feeling of lustrous image, and not thing like contrast ratio itself.
Do you remamber when DVD arrive, got more popular, and the good editions started with new transfer in progressive scans, from good hi end telecine machines, better color correction than the usual TV tapes of movies we were used ?
It looked very nice on good CRT TVs, like sony trinitron flat screen. It was great for the time. But when the first PC DVD kits arrive, using Power DVD, and we noticed that the image on computer CRT monitor did never looked like on TV in terms of contrast. It lloked faded, dark in shadows, and no matter what adjust setting we tried on Power DVD, like contrast, brightness, saturation, the image conrast never looked good like in a CRT TV, cause the brightness adjust made the image whitish (like airbrushed transparent paint over), without density, and the contrast adjust would just create clipped highlights and crushed shadows. There was no way to get the pleasant contrast like from a DVD played of a CRT TV, by using a computer CRT monitor in a PC DVD kit.
Later someone told me there was a difference from a CRT computer monitor compared to a CRT TV, like one was designd for high contrast signal, and the other designed to low contrast signal. So a TV and a computer monitor, in the CRT era (before LCD start to domain market) would never be look like, one to another, for watch good quality DVD films.
But today, since LCD TVs and LCD computer monitor dominated the market, this difference is not more like before. I try the best image from a DVD or Blu ray on a computer LCD monitor and in a LCD TV, and both have the same limitations, very similar contrast, after trying the best settings for both.
The LCD TVs got many of the negative aspects from the PC DVD kit watched on CRT PC monitor had. It get fadded unless you push contrast and kill highlights and shadows details. For me this is really very sad, and I have no patience for watching LCD TVs, prefering a CRT despite be 480p screen resolution.
How and why this happened, this “homologation of contrast standart” between computer screen and TV screens ? Why they choosed a contrast standart that would create problems for watrching films on TV, causing the killing of dynamic range by destroying highlifgts and shadow details, while CRT TVs did not destroyed like that ?
For me this is so evident… I don’t know why people did not complained…
Now they created the HDR… but for me HDR mostly just tries to fix a problem that was created while introducing LCD TVs with a contrast standart thay lead highklights and shadows details to be killed. The industry tried to create video transfer more glossy, to try compensate the faded basic look of LCD TV. But even so all LCD TVs have very poor dynamic, unless we adjusted it to have faded look, or unless you have HDR.
All this and people stay silent… Why peole are so tolerant with the loss of good contrast and good dynamic from CRT times?
I bet even OLED TVs have some this problem, due the new contrast standart, result from the homologation of standarts between computer monitors and TVs. But all OLED models I saw on stores was running HDR videos, so I need to see it again, running a non HDR video, to be sure.
