DisplayPort High Bit Rate (HBR)

DisplayPort High Bit Rate (HBR) was the standard bandwidth that came with DisplayPort 1.0, 1.1 & 1.1a video cards. It has now been replaced with HBR2 (the vast majority of video cards made in 2014) and then with HBR3 (mid-2015).

The data bandwidth represent the maximum information (in gigabytes per seconds) each version of DisplayPort can send to the output. Because of this shared bandwidth, it is possible to connect many monitors of different make, model, resolution and refresh rate on each cable.

The total bandwidth of High Bit Rate connections is 10.8 Gbit/s, the Video Data Rate being 8.64 Gbit/s.

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)
• One 1920 x 1080 at 60 frames per second (hertz)
• & all lower resolutions and the ones in between.
