Shall provide picture controls for brightness, contrast, and detail, as well as horizontal and vertical sizing, positions, and zoom for both Preview and Program output buses Because the standard has evolved over the years, not all DisplayPort cables will work properly at the latest speeds. The original Display 1.0-1.1a spec allowed for RBR (reduced bit rate) and HBR (high bit rate) cables, capable of 5.18 Gbps and 8.64 Gbps of data bandwidth, respectively. DisplayPort 1.2 introduced HBR2, doubled the maximum data bit rate to 17.28 Gbps and is compatible with standard HBR DisplayPort cables. HBR3 with DisplayPort 1.3-1.4a increased things again to 25.92 Gbps, and added the requirement of DP8K DisplayPort certified cables. Hi all! Before i get started just wanted to say all replies are GREATLY appreciated, Thank you so much! I've been doing a bunch of research on Displayport switchers for monitors and i plan on buying one but it seems the one i actually need doesn't actually exist.. I wanted to reach out to you guys sorta out of desperation to see if anyone has actually heard of one of these. But basically what I'm needing is a display port switcher for a single monitor that basically switches the display between two computers. Now this sounds very easy to find, you can find these all over the internet right? But i need one that has HDMI + DP support. On top of this i may need 144hz for my gaming monitor because if i didn't have this i would just completely outright lose the 144hz that i payed for. I have considered buying like a HDMI to DP adapter and trying to plug it in to a display port switcher but I'm not even sure if that would work correctly or optimally at all. Does anyone have any advice for me or potential Displayport Switchers that sorta meet my requirements? I guess my situation sorta is a super unusual one. All replies are greatly appreciated, Thank you!
Display timings are relatively complex calculations. The VESA governing body defines the standards, and there's even a handy spreadsheet that spits out the actual timings for a given resolution. A 1920x1080 monitor at a 60 Hz refresh rate, for example, uses 2,000 pixels per horizontal line and 1,111 lines once all the timing stuff is added. That's because display blanking intervals need to be factored in. (These blanking intervals are partly a holdover from the analog CRT screen days, but the standards still include it even with digital displays.) Shall provide two (2) independent video buses that shall enable the operator to view video prior to audience display I will say that I have an Acer XB280HK 4K60 G-Sync display that only has a single DisplayPort input, and it powers up or wakes from sleep almost instantly. I have an Acer G-Sync Ultimate 4K 144Hz HDR display meanwhile that takes about 7 seconds to wake from sleep. Rather annoying. I know that HDMI can be very slow (depending on monitor)... sometimes as much as 5 seconds to see the new source. I assumed that was content protection built into the standard and/or slow decoder ASIC. HDMI cable requirements have changed over time, just like DisplayPort. One of the big advantages is that high quality HDMI cables can be up to 15m (49.2 feet) in length — five times longer than DisplayPort. That may not be important for a display sitting on your desk, but it can definitely matter for home theater use. Originally, HDMI had two categories of cables: category 1 or standard HDMI cables are intended for lower resolutions and/or shorter runs, and category 2 or “High Speed” HDMI cables are capable of 1080p at 60 Hz and 4K at 30 Hz with lengths of up to 15m.You might think it's a simple matter of hooking up whatever cable comes with your monitor to your PC and calling it a day, but there are differences that can often mean a loss of refresh rate, color quality, or both if you're not careful. Here's what you need to know about DisplayPort vs. HDMI connections. HDMI splitters that send two, three, four, or more signals from a single HDMI source are available, but for consumers, two is usually enough. Splitters with more outputs are primarily for business and commercial use, where one source needs to be sent to multiple TVs or projectors. Thankfully, most DisplayPort problems are relatively easy to avoid or fix. Here are four common DisplayPort problems, along with advice for diagnosing and solving them. Display Adapter Link Failure With a maximum data rate of 25.92 Gbps, DisplayPort 1.4 can handle 4K resolution 24-bit color at 98 Hz, and dropping to 4:2:2 YCbCr gets it to 144 Hz with HDR. Alternatively, DSC allows up to 4K and 240 Hz, even with HDR. Keep in mind that 4K HDR monitors running at 144 Hz or more carry premium pricing, so gamers will more likely be looking at something like a 144Hz display at 1440p. That only requires 14.08 Gbps for 24-bit color or 17.60 Gbps for 30-bit HDR, which DP 1.4 can easily handle.
Shall be equipped with an internal, universal AC power supply with a seven- (7) year parts and labor warranty There are now cards with DisplayPort 2.1 support, but they're still of different levels. Intel's Arc GPUs support 10 Gbps per lane, for a 40 Gbps maximum connection speed (not including 128b/132b encoding). AMD opted for the faster 13.5 Gbps per lane (54 Gbps total), but neither company supports the potential 20 Gbps per lane variant. But perhaps the bigger issue now isn't GPU support.Shall provide internal video test patterns and pink noise generator for calibration and setup of display devices Both HDMI and DisplayPort can also carry audio data, which requires bandwidth as well, though it's a minuscule amount compared to the video data. DisplayPort and HDMI currently use a maximum of 36.86 Mbps for audio, or 0.037 Gbps if we keep things in the same units as video. Earlier versions of each standard can use even less data for audio. One important note is that HDMI supports audio pass through, while DisplayPort does not. If you're planning to hook up your GPU to an amplifier, HDMI provides a better solution. I have not compared switch latency to Display Port, so would be curious if anyone here has impressions Provide a seamless switcher that shall support video resolutions up to 4K @ 60 Hz over HDMI and DisplayPort inputs from multiple sources to Program and Preview HDMI outputs The first clue to a DisplayPort link failure will probably be your monitor switching to low resolution. This mainly affects AMD GPUs and usually occurs after waking your computer and monitor from sleep.
If you have a 4K Ultra HD TV and 4K source components, the switcher must also be 4K compatible. If you need to pass HDR-encoded or 3D video signals, your HDMI switcher must have those capabilities. at a fixed 144 Hz refresh rate and 24-bit color works just fine on DisplayPort 1.2 or higher, as well as HDMI 2.0 or higher. Anything lower than that will also work without trouble on either connection type. About the only caveat is that sometimes HDMI connections on a monitor will default to a limited RGB range, but you can correct that in the AMD or Nvidia display options. (This is because old TV standards used a limited color range, and some modern displays still think that's a good idea. News flash: it's not.) Shall allow two (2) HDMI inputs to cause a connected matrix switcher with HDMI outputs to emulate a seamless switcher Shall provide upscaling and downscaling of input sources with 30-bit precision processing and 4:4:4 color bandwidth Shall provide selectable, human-readable visual confirmation of HDCP compliance when encrypted content is sent to a non-HDCP compliant displayAMD gamers have a few more options, at least with RX 7000-series cards. You can find DisplayPort 2.1 monitors and TVs, if you look hard enough. Maybe. The Asus ROG Swift PG32UXQR for example supports DisplayPort 2.1, but it hasn't officially released yet (and it's not the same as the previous PG32UXQ). HDMI 2.1 connectivity is also sufficient, and there are more displays available. Keep in mind that maximum bandwidth of the RDNA 3 GPUs is 54 Gbps over DisplayPort 2.1, or 48 Gbps over HDMI 2.1, so it's not a huge difference. Most AMD RX 7900-series cards that we've seen include two DisplayPort 2.1 ports, and either two HDMI 2.1 or a single HDMI 2.1 alongside a USB Type-C connection. Shall include technology to authenticate and maintain continuous HDCP encryption and key exchange between connected devices Shall provide audio extraction of HDMI and DisplayPort multi-channel audio to the Program analog audio output When in FILL mode, the video image on the output screen shall always fill the output screen without letterbox or pillar box You can use an HDMI switcher with two HDMI outputs to send the same HDMI signal to two TVs or a video projector and TV, but you can use an HDMI splitter if you don't need a switcher.
The standard in the past has been 24-bit color, or 8 bits each for the red, green and blue color components. HDR and high color depth displays have bumped that to 10-bit color, with 12-bit and 16-bit options as well, though the latter two are mostly in the professional space. Generally speaking, display signals use either 24 bits per pixel (bpp) or 30 bpp, with the best HDR monitors opting for 30 bpp. Multiply the color depth by the number of pixels and the screen refresh rate and you get the minimum required bandwidth. We say 'minimum' because there are a bunch of other factors as well. If you're wondering about Thunderbolt 2/3, it basically just routes DisplayPort over the Thunderbolt connection. Thunderbolt 2 supports DisplayPort 1.2, and Thunderbolt 3 supports DisplayPort 1.4 video. It's also possible to route HDMI 2.0 over Thunderbolt 3 with the right hardware.The Radeon software should alert you to the problem with an error message, but this is easy to miss when it pops up. Open the Radeon software and have a look at the notifications. The message will be:
