2020年12月11日 · DisplayPort 1.3 added HBR3 mode which is only 50% faster than HBR2 (HBR2 is two times HBR and HBR3 is three times HBR), and DisplayPort 1.4 does not add higher transmission speed, only support for DSC. At 8 bits, a single cable is enough to support 120 Hz, but not 144 Hz. Using two cables fixes that. Are two cables supported by monitors? Yes.

Since there is no definition of what constitutes a "DisplayPort 1.4" device, some manufacturers may choose to label these as "DP 1.2" devices despite their support for DP 1.4 HDR extensions.[49] As a result, DisplayPort "version numbers" should not be used as an indicator of HDR support.' The 650/850UK's are 4k @ 60Hz only, so this would make ...

2021年1月13日 · HDMI 2.0 has 18 Gbps theoretical max bandwidth while DisplayPort 1.2 has ~22 Gbps. In real world usage, you tap into 80-90% of the max rate which is why you get up to 4K 60 FPS 10 bit over DP 1.2 versus 4K 60 FPS 8 bit over HDMI 2.0.

2020年10月1日 · No "DisplayPort 1.2 cables" and no "DisplayPort 1.4 cables". All DisplayPort cables are completely identical. There is a string of copper connecting pin 1 on one side to pin 1 on the other side, and another string of copper connecting pin 2 to pin 2, and so forth.

2021年11月12日 · According to Wikipedia DisplayPort article here, 1440p@144 Hz with 10-bit color depth needs 17.60 Gbit/s, which the DisplayPort 1.2a can't support at standard CVT-R2 signal timing, but if both the display and video card supports it, tweaking the video signal timing parameters could theoretically work.

2017年8月17日 · How to daisy-chain monitors (with DisplayPort) from Thunderbolt USB Type-C ports, like the new 2016 Macbook Pro? 4 What's the compatibility story for DisplayPort 1.4 and Thunderbolt 3.0?

2017年10月8日 · so much wrong here, wiki says: "DisplayPort version 1.3 was approved on 15 September 2014.[19] This standard increases overall transmission bandwidth to 32.4 Gbit/s." and we are on 1.4 now, same speed tho, just more features. "HDMI 2.0 increases the maximum TMDS clock to 600 MHz (18.0 Gbit/s).[110]

2013年8月11日 · This isn't an NVIDIA-only thing. It's a monitor hardware thing. Displayport, I believe, has a HPD pin ("hot plug detect"). I believe that what happens is that when the monitor turns off, it brings that pin low, which then causes Windows to detect the display as disconnected, and then disables it.

2023年1月12日 · Displayport 1.2 is limited to 144Hz. This isn't entirely true, depending on which features of DP 1.2 it actually supports. 1.2 can do 240Hz at 1080p as long as it supports HBR2 (which some early DP 1.2 devices did not). Max refresh rate for 1.2 with HBR2 at 1080p is 288Hz with 8-bit color, and 237Hz with 10-bit color.

2015年12月26日 · From online I have read that I need to "change the DisplayPort mode from 1.1 to 1.2" however I cannot find where to do this! Some extra info: -Windows 8.1 64 bit -Geforce GTX 770 -Dual monitors, 4k connected by displayport cord, …
