In order to match that standard, those old six-bit panels use Frame Rate Control to dither over time. This covers the expanded range of luminance (that is, brightness) that HDR can cover, but what about color? The other thing to note here is that in general, the fewer bits, the better. As far as I know windows menu isn't 12 bpc. Now, it's never been exactly clear what the bit depth is on the last-gen KUROs, whether it was native 8-bit, 10-bit with dithering, or native 10-bit. Generally, though, its good enough that you wont see it unless youre really looking for it. The screen will just go black, or else be very buggy, if it doesn't work. Currently, the most commonly used answer comes from the Barten Threshold, proposed in this paper, for how well humans perceive contrast in luminance. In computer programming, variables are stored in different formats with differing amounts of bits (i.e., ones and zeros), depending on how many bits that variable needs. However, the BT 2020 gamut is a little more than double the sRGB gamut, meaning you need more than one extra bit to cover it without banding. Somebody can show me, how i can see difference with 8bpc vs 12bpc (bits per channel) some special pictures? That's also the only place this trick is needed, because after being transferred from a camera (or what have you) to a device on which you'd watch the content, today's HDR signals already come with a not dissimilar trick of metadata, which tells the display the range of brightness it's supposed to display at any given time. If it works, things will look similar but you may see less banding and blockiness in dark areas than you otherwise would. When the BT2020 color gamut is usable on devices like monitors, TVs, and phones, and those devices are able to reach a much higher brightness, that's then you can think about 12 bits. We should note, though, that currently this is found exclusively in high-end reference monitors like those from Eizo. Absolutely all other 1.xx versions can handle maximum 4K @ 30fps. For this post, let's assume I only use this TV to play Xbox games and not for any other content. This is part of the reason why HDR10, and 10-bit color (the HLG standard also uses 10 bits) is capped at outputting 1k nits of brightness, maximum, instead of 10k nits of brightness like Dolby . I understand that which option is best can depend on a number of different factors, including the native bit depth of the source, the native bit depth of the display, the processing capabilities of the display, and the bandwidth limit of the One X's HDMI port. My RTX3080 10 has no signal output, but if I press the power button of te PC it shuts down the system immediately, My GT 1030 with a DVI D port won't output 120hz to my monitor that also supports 144hz. JavaScript is disabled. You'd need a professional monitor for that kind of setting. I understand that which option is best can depend on a number of different factors, including the native bit depth of the source, the native bit depth of the display, the processing capabilities of the display, and the bandwidth limit of the One X's HDMI port. Banding is a sudden, unwanted jump in color and/or brightness where none is requested. First, based on observations, eight-bit color done in the non-HDR sRGB standard and color gamut can almost, but not quite, cover enough colors to avoid banding. HDMI 1.3 or higher support up to 16 bit @ 1080p. Hi, I'm using a Samsung Full HD SmartTV which I read that uses YCbCr 444 format. It gets expanded out by the TV in the end. SDR games are rendered in 8-bit on the Xbox. flipped around to its maximum setting possible, theres a decent chance youll notice a bit of banding there, very few people can notice the difference between 12-bit and 10-bit signals, Early Black Friday Deals on PC Hardware: Latest GPU, CPU and PC Sales, AMD's Data Center Sales Set Records, Consumer Products Disappoint, Anycubic Photon M3 Premium Printer Review: Top of the Line, ASRock's Side Panel Turns Your Case Into a Secondary Display, Russia PC Shortages Spark Wave of PC Upgrades. The third and final piece is when to worry about 12-bit color. Is there any harm in using 12-bit? Also there is the problem of the output color depth, 8 bpc or 12 bpc? There was a problem. After his war rating tried to go negative, he flipped around to its maximum setting possible. (P.S. The Dolby Vision standard uses 12 bits per pixel, which is designed to ensure the maximum pixel quality even if it uses more bits. The settings will revert back to what they were before the change. Tom's Hardware is supported by its audience. Without pushing the brightness range a lot, you can keep apparent banding to a minimum. First, should you worry about the more limited color and brightness range of HDR10 and 10-bit color? Instead, it tries to hide banding by noisily transitioning from one color to another. The One X has an HDMI 2.0 port, giving it a max bandwidth rating of 18 Gbps. Btw Nvidia DSR can output 60Hz 4K @ HDMI 1.4x by 1080p screen. 4:2:2 and 4:2:0 save bandwidth by compressing colour (although how visible this is depends on the item that's being shown.) So if you need to count up to two (excluding zero), you need one bit. A LUT is used to correct an the color of an image. Check out my gear on Kit: https://kit.co/fadder8In this video we discuss what color depth is, and what the benefits of having 10-bit color over 8-bit color. Please refresh the page and try again. When asking this question elsewhere, I've been told by some people that you have to use 8-bit for correct SDR playback, and by other people that you do not need 8-bit for correct SDR playback. The 970 has a limited color output. Its the type of bug that initially caused Gandhi to become a warmongering, nuke-throwing tyrant in Civilization. So to convert from 8-bit to 10-bit just multiply the value by 4. Welcome to TechPowerUp Forums, Guest! In general, each bit you add allows you to count up to double the previous number and store double the previous amount of information. The higher you can count, in this case for outputting shades of red, green, and blue, the more colors you have to choose from, and the less banding youll see. If it doesn't work and you get a black screen, just wait 30 seconds or so without pressing any buttons. If the game or the OS sets the video buffers to 10 or 12 bit the console will output 10 or 12 bit.". So, let's assume my TV can reliably handle 10- and 12-bit sources. (10-bit = 1024 values, 8-bit = 256 values). The point about underflow is an unhelpful digression. Future US, Inc. Full 7th Floor, 130 West 42nd Street, New York, The sRGB standard calls for eight bits per color channel to avoid banding. Heres why you can trust us. Two bits allow you to count up to four, three bits up to eight, and so on. This, hopefully, hides the banding. Im install this new driver and find this feature. Going over your limit is one of the most common software errors. I connected it via HDMI to my gtx 970 video card, and in the nvidia control panel I get the options to use either RGB ( Limited or Full), YCbCr 422 (if I use this one colors are really bad) and YCbCr 444. RGB and YCbCr are colour formats. Only HDMI 2.0 and new version can handle 4K @ 60fps. Get instant access to breaking news, in-depth reviews and helpful tips. Somebody can show me, how i can see difference with 8bpc vs 12bpc (bits per channel) some. Can't see BIOS through HDMI output on GTX 1050TI. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Quadro P620 won't output a signal to the monitor ? NY 10036. may be my screen cant handle 12bpc. I don't think your Samsung TV has 12bit colour depth. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Once the industry gets to that point, 10-bit color isn't going to be enough to display that level of HDR without banding. (In the One X's video settings, all of the 4K and HDR options are grayed out for me.). Cookie Notice With this in mind, it may be helpful to note my current setup. The lowest-end displays (which are entirely uncommon now) have only six bits per color channel. We covered how many bits you need for luminance already, but how many bits do you need for a higher gamut? You can try the 12 bpc setting to see how it goes. This makes it possible for me to keep delivering great content for you all.Thank you for the support! Fortunately, this will almost always be listed in a device's tech specs, but beware of any HDR display that doesn't list it. Im install this new driver and find this feature. Graphics card outputs no picture, but the iGPU does ? How many bits are needed to cover a color gamut (the range of colors a standard can produce) without banding is harder to define. Dithering, on the other hand, doesnt have those in-between colors. Because a lot of content is mastered and transmitted in 10-bit color, 12-bit color hardware isn't going to do much for you today anyway. http://www.techpowerup.com/forums/threads/12-bit-hdmi-color-output-in-cat-14-6.202188/, http://www.samsung.com/uk/consumer/tv-audio-video/televisions/flat-tvs/UE48H6200AKXXU, Intel Core i7-3930K BOX HT On @ 4.71Ghz - 1.424v [Offset +0.035] / VCCSA - 0.950v, ASUS ROG Rampage IV Extreme rev 1.02 [bios 4901 modded], Samsung Original 16GB DDR3 (DH0-CH9 44) @ 110ns [2.41Ghz] 11-11-11-28 (1T) Quad Channel 1.525v, ASUS ROG Poseidon GTX780 Platinum [2-Way SLI] @ 1200/6600 - 1.150v (both cards revision B1), SSD 128GB OCZ Vertex 4 + 1.5TB Raid0 3x500GB HDD Seagate + 1TB HDD Seagate + 500GB Toshiba HDD, Samsung UE48H6200AKXRU 48' Smart-TV 3D [S-PVA PSA 5ms], CHIEFTEC APS-850C Modular (80+ Bronze) @ 850W, http://valid.canardpc.com/2609985 http://valid.canardpc.com/2hgtzt http://valid.canardpc.com/dwqmsh, 16GB (2 x 8GB Corsair Vengeance Black DDR3 PC3-12800 C9 1600MHz), Samsung 850 Pro 256GB | WD Black 4TB | WD Blue 6TB, BenQ XL2720Z (144Hz, 3D Vision 2, 1080p) | Asus MG28UQ (4K, 60Hz, FreeSync compatible), Creative Sound Blaster X-Fi Fatal1ty PCIe, Microsoft Intellimouse Pro - Black Shadow, Zotac GTX 980TI AMP!Omega Factory OC 1418MHz, X-Fi Titanium HD @ 2.1 Bose acoustimass 5. So the million-dollar question: since I can only use this setup with 1080p output (meaning no 4K and HDR settings active on the console-side), which one should I use?

This is ambiguous, though, because it could mean that the panel merely accepts 10- and 12-bit signals (which I can confirm it does) as opposed to actually rendering those bit depths on screen, similar to how most 720p TVs can accept 1080p signals but will then downscale the signal to their native resolution of 720p. The two HDR gamuts have to cover a huge range of brightness and either the P3 color gamut, which is wider than sRGB, or the even wider BT2020 color gamut. Human color vision is dependent on opsins, which are the color filters your eye uses to see red, green, and blue, respectively. Sorry for the long post but if I keep it too short and open-ended I tend to get answers that are too general in nature and unhelpful for my current setup. Gpu output not working, Gpu not showing in device manager. The other trick display manufacturers use involves look up tables. Before we dive into that, the first question is what is bit depth, and why does it matter for displays? when i can read some info about it? The question, then, is how many bits do you need for HDR? The final nuance here is the bandwidth limit of the One X. Privacy Policy. The second thing is how to ensure you're getting 10-bit color on your monitor. This, in turn, means more bits of information are needed to store all the colors and brightness in between without incurring banding.
