Used HDR TV: Panasonic TX-55GZW954 (2019 model). It has an OLED screen from LG but much better processing, resulting in almost no banding and no crushed blacks. OLED does not need the local dimming of LCD.

I always thought, "if you want to show HDR video on a non-hdr screen, just make everything dimmer but set the brightness to max." This video is a pretty good demonstration of that. It's a bit ironic, though, that this is an SDR video that I'm watching on my HDR-supported phone.

My phone has HDR but sadly it's fake HDR from what I understand out of it... 1st the brand claims 900 nits peak brightness and all I get is like 400nits best, 2nd the bit rate of the screen is low and very low processing power which has very high color banding problems, 3rd the HDR brightness is so stupid that is seems to be just a "full" screen dimming\brightening which basically simple seems to be moving the brightness control on android up and down instead of actually be doing that realistically pixel-by-pixel on the screen like it should because increasing the general brightness simply also increases the lower nits part of the image brightening them up too which is sad..., 4th anyway it's the first TCL smartphone (TCL 10 Pro) so yeah, I guess they "tried", even their own first OLED in the phone looks very different to any other brand, but not in a good way 😁

@yuxuanhuang3523 Жыл бұрын

I tried KZfaq HDR and I don't know if it's the problem with my device or the video. Everything switches to P3 colorspace and gets over saturated. Peak brightness doesn't get any improvement over SDR either, it just dimmed everything else except the subtitles, which is terrible so I turned off CC. By the way it's a Huawei flagship phone soI had to find a alternative way to use KZfaq on it. But again the same problems happen on my windows computer with HDR enabled display.

If your TV has a 'Game mode', turning it on will usually turn off the vast majority of image processing in the TV. This both reduces latency and prevents the TV from doing image processing in an image that it expects your computer/ console has already processed.

The thing that entices me about HDR, from what I understand about it, is the added color depth. At least, from what I remember reading about it like a year or two ago. As a digital artist, it'd be great to smudge my fake paint around and get smoother gradients between different values. And then, of course, I'd want to share my work around with that color depth for anyone with an HDR monitor to enjoy. Being able to shine a believable facsimile to the sun in people's faces would also be nice.

@genewitch 3 жыл бұрын

that's just leaving "Standard RGB Space" which is 8 bits per pixel. Having pixels or displays that can handle more than 8 bits allows more colors without obvious artifacting/banding. I even have a display that only technically has 7 bits per pixel, but trades the color depth for viewing angle and grey to grey speed. AFAIK 10bit is more common now than 10 years ago, which is over a BILLION COLORS!

hdr standards aren't really special, but they give permission to (mostly amateur) creators to embrace it, use the extended brightness range, have more detail in the lows. honestly the brightness scaling is still wack in most content, its worth pursuing in moderation. 10-bit colour is more important. 8-bit colour depth in HDR content looks very silly, very exaggerated colour banding in digitally created scenes with no dithering. in that case, it is literally no different to SDR except the distance between light and dark

8bit is not HDR by definition. What you call HDR in 8bit is simply crushing the blacks and cranking up the contrast. AKA joining the hype BANDwagon.

@joesterling4299 Жыл бұрын

Yes. Brighter displays. Deeper blacks. More bits per color primary. This is what matters. "HDR" is just some marketing label, since any display that can ace all the vital parameters is going to look "HDR" when displaying high-quality content. It's a continuous gradient of improvement in the tech, and "HDR/SDR" makes it seem like there's a wall between two very different things. Not so.

This is actually a terrible video full of all sorts of misinformation. From what HDR is (e.g. there's no mention about even basic things like added bit depth...), to a total lack of understanding of how the TV actually does it, just blindly ignoring huge parts of the market like OLEDs which do not cause blooming because it's not local dimming, and the ridiculous suggestion of just turning off every setting such as denoiseing. E.g. many of those settings actually bring the image back to closer to what was originally intended, because they account for things like artifacts introduced by the compression algorithms, or the display technology, etc etc. If you want actual good information on this, then I'd strongly suggest channels line HDTVTest and sites like rtings, especially HDTVTest who is hilarious, and can tell you exactly which TV's do what well, what settings to keep on and what they do, etc. Really it's disappointing this video is getting any attention with such an extreme lack of understanding. Failing to mention OLEDs is just insane given how absurdly popular OLED TVs are becoming. HDR is one of the best things to happen to media in a long time, far better than just ever increasing resolution.

the most important part of hdr is the increased bit depth from 8 bits per channel to 10 bits. now instead of R, G, and B values being defined on a scale from 0-255, it's from 0-1023. In addition, HDR uses a PQ curve instead of a gamma curve, which means more detail and less banding in darker areas.

@muhamadardiyansah446 Жыл бұрын

You mean 0-255 or 0-1023 right?. And yes PQ curve gives more information to the dark areas because as you said less banding and more detail to those areas, not only that, but also human eye is more sensitive to dark areas. That's why deep black screen is the required spec to show HDR content 😉

The interesting thing about the video is it's not very technical but the way you describe HDR, how it works on different TV's, especially the ones that can't reach industry standard levels (almost every consumer TV) is super accurate! What you say about how SDR screens show HDR content is also how most consumer HDR panels do it. And that's great because my 1800 nit TV would look completely blown out trying to show Dolby Vision content at 4000 nits.

2:43 Warning, the following text is a rant I contained for months: Speaking of useless TV settings, my home has an old Sony Bravia. I'll list the most annoying settings: 1. Clear White: Enabling this changes the *color temperature* of colors near the white grayscale to be more neutral and less *yellow.* That's right, the TV *CONSTRAINS* only the white colors to have a redish tone *BY DEFAULT.* 2. Advanced Contrast Amplification: I can't even begin to describe my hatred for this infamous setting. It messes up the color scale, adds banding artifacts, and dynamically changes how an image is displayed in real-time. It also comes with a "deep black" feature that just turns off the backlight when MANY SECONDS of pure blackness have passed. This is an energy-saving feature! it should be independent from image post-processing and be located in the "Eco" category of settings! If it REALLY amplified contrast, the TV should react instantly to a black frame being displayed. And I'm not exaggerating, the TV has a "LED Movement Mode" which flickers the backlight at 60Hz to achieve fluid animation like PWM screens. It would be as easy to include a dedicated hardware chip to check if every pixel in a frame is black while the screen is doing a progressive (linear) scan, that doesn't consume much memory, nor energy. 3. Live Color: this *doesn't oversaturate colors,* it just unlocks the full saturation range (just like Clear White unlocks grayscale). The colors only get oversaturated when you set it to max value, mid and low are fine. 4. Gamma: I actually like having control over this setting, but the fact that it has a range of integers from -3 to +3 while barely changing the grayscale is so dumb. There are even more settings I hate but this comment is too long and I forgot about them lol

I myself can't notice the flicker in the display I mentioned, probably because the frequency is high enough or the pulse width is long.

In essence hdr is just that but there's a lot more to it, color space is a lot wider making it possible to display saturation levels that don't fit in sdr signal. the signal is encoded in completely different way too, sdr signal need to be gamma corrected and the way gamma curves and maximum display brightness are configured can make image look completely different from BT709 standard which is gamma of 2.2 at maximum white luminescence of 100nits; hdr signal directly incorporates absolute per pixel brightness level making it easier to get accurate image, and easier to calibrate the display.
