What is DisplayPort HBR2?

DisplayPort version 1.2 was introduced on 7 January 2010. The most significant improvement of the new version is the doubling of the effective bandwidth to 17.28 Gbit/s in High Bit Rate 2 (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth.

What is HBR2 and HBR3?

HBR2 is DP 1.2, uses 5.4 Gbps maximum data rate. • HBR3 is DP 1.4, uses 8.1 Gbps maximum data rate.

Can all DisplayPort cables do 4K?

A standard DisplayPort cable, including older cables, will work for any DisplayPort configuration including 4K and multi-stream capabilities. All certified DisplayPort cables support HBR2 (High Bit Rate 2), which can support 4K at 60Hz, or up to four 1080p displays using multi-stream.

What is HBR1?

Note: Can also be called DisplayPort High Bit Rate 1 (HBR1) In this mode, you’ll be able to connect monitors with these resolutions: One 3840 x 2160 (4K) at 30 frames per second (hertz) One 2560 x 1600 at 60 frames per second (hertz) One 1920 x 1200 at 60 frames per second (hertz)

Do I need HBR3?

When it comes to cables it’s either HBR, HBR2 or HBR3. DP version numbers are only relevant to the port itself and not the cable. Some features included in advanced DP iterations like 4k 144Hz or 8k 60Hz may need increased bandwidth and an HBR 3 cable may be needed. For 1440p 165Hz / 4K 60Hz HBR2 is fine.

Does DisplayPort 1.2 support 144Hz?

For 1080p 144Hz you will need DisplayPort, Dual-Link DVI, or HDMI 1.3 (or higher), while 1440p 144Hz requires either HDMI 2.0 or DisplayPort 1.2. This author has been vetted and has the necessary know-how or education to be able to write about this topic.

Does DisplayPort 1.2 support 4K?

DisplayPort 1.2: Supports up to 4K at 60Hz, some 1.2a ports may also support AMD’s FreeSync. DisplayPort 1.3: Supports up to 4K at 120Hz or 8K at 30Hz. DisplayPort 1.4: Supports up to 8K at 60Hz and HDR.

Is DisplayPort better than DVI?

DVI: Video only, perfect for older systems or for 144Hz at 1080p. DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.
