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. Standard available to all VESA members [ dubious – discuss] with an extensible standard to help broad adoption [68] 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. pins for external connectors on desktops, notebooks, graphics cards, monitors, etc. and 30/20 pins for internal connections between graphics engines and built-in flat panels.
All features of DisplayPort will function across any DisplayPort cable. DisplayPort does not have multiple cable designs; all DP cables have the same basic layout and wiring, and will support any feature including audio, daisy-chaining, G-Sync/ FreeSync, HDR, and DSC. This exemplifies why DisplayPort cables are not classified by "version"; although DSC was introduced in version 1.4, this does not mean it needs a so-called "DP 1.4 cable" (an HBR3-rated cable) to function. HBR3 cables are only required for applications which exceed HBR2-level bandwidth, not simply any application involving DisplayPort 1.4. If DSC is used to reduce the bandwidth requirements to HBR2 levels, then an HBR2-rated cable will be sufficient. Long story short, it's cheaper to go all digital from a manufacturing perspective, no more A to D conversion, and the picture looks better anyways. They probably just don't have the A to D hardware in the monitor and really didn't gear the thing for people putting the adapter on the other end. The DP8K certification was announced by VESA in January 2018, and certifies cables for proper operation at HBR3 speeds (8.1 Gbit/s per lane, 32.4 Gbit/s total).

Common, but old.
The maximum limits for the RBR and HBR modes are calculated using standard data rate calculations. [50] For UHBR modes, the limits are based on the data efficiency calculations provided by the DisplayPort standard. [51] :§3.5.2.18 All calculations assume uncompressed RGB video with CVT-RB v2 timing. Maximum limits may differ if compression (i.e. DSC) or Y′C BC R 4:2:2 or 4:2:0 chroma subsampling are used. Reduced bandwidth transmission for 15-metre (49ft) cable, at least 1920 × 1080p @ 60 Hz at 24 bits per pixel so what I'm trying to find out is if there is another adapter i could use to get the second monitor to connect and work properly. DisplayPort version 1.3 was approved on 15 September 2014. [19] This standard increases overall transmission bandwidth to 32.4 Gbit/s with the new HBR3 mode featuring 8.1 Gbit/s per lane (up from 5.4 Gbit/s with HBR2 in version 1.2), for a total data throughput of 25.92 Gbit/s after factoring in 8b/10b encoding overhead. This bandwidth is enough for a 4K UHD display ( 3840 × 2160) at 120 Hz with 24 bit/px RGB color, a 5K display ( 5120 × 2880) at 60 Hz with 30 bit/px RGB color, or an 8K UHD display ( 7680 × 4320) at 30 Hz with 24 bit/px RGB color. Using Multi-Stream Transport (MST), a DisplayPort port can drive two 4K UHD ( 3840 × 2160) displays at 60 Hz, or up to four WQXGA ( 2560 × 1600) displays at 60 Hz with 24 bit/px RGB color. The new standard includes mandatory Dual-mode for DVI and HDMI adapters, implementing the HDMI 2.0 standard and HDCP 2.2 content protection. [20] The Thunderbolt 3 connection standard was originally to include DisplayPort 1.3 capability, but the final release ended up with only version 1.2. The VESA's Adaptive Sync feature in DisplayPort version 1.3 remains an optional part of the specification. [21] 1.4 [ edit ]
