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. 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. The latest display connectivity standards are DisplayPort and HDMI ( High-Definition Multimedia Interface). DisplayPort first appeared in 2006, while HDMI came out in 2002. Both are digital standards, meaning all the data about the pixels on your screen is represented as 0s and 1s as it zips across your cable, and it's up to the display to convert that digital information into an image on your screen. 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. Shall include technology to authenticate and maintain continuous HDCP encryption and key exchange between connected devices
Shall provide internal video test patterns and pink noise generator for calibration and setup of display devices Make sure that your HDMI switcher is compatible if you are routing the output of the switcher through a home theater receiver that provides decoding for advanced audio formats, such as Dolby TrueHD, Atmos, DTS-HD Master Audio, DTS:X. For Nvidia gamers, your best option right now is a DisplayPort 1.4 connection to a G-Sync certified (compatible or official) display. Alternatively, HDMI 2.1 with a newer display works as well. Both the RTX 30-series and 40-series cards support the same connection standards, for better or worse. Most graphics cards will come with three DisplayPort connections and a single HDMI output, though you can find models with two HDMI and two (or three) DisplayPort connections as well — only four active outputs at a time are supported.

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.) When in FOLLOW mode, the video image on the output screen shall always preserve the original aspect ratio of the input signals Shall allow any input image to be displayed on-screen simultaneously with another image for picture-in-picture – PIP display and allow: DSC can provide up to a 3:1 compression ratio by converting to YCgCo and using delta PCM encoding. It provides a "visually lossless" (and sometimes even truly lossless, depending on what you're viewing) result. Using DSC, 8K 120 Hz HDR is suddenly viable, with a bandwidth requirement of 'only' 42.58 Gbps.
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 one (1) bidirectional RS-232 3-pole captive screw connector on rear panel for RS-232 controlThere 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. 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.
