Summary
HDMI 1.4: Supports up to 4K (4,096 by 2,160) at 24Hz, 4K (3,840 by 2,160) at 30Hz, or 1080p at 120Hz.
HDMI 2.0: Supports up to 4K at 60Hz, and later versions (HDMI 2.0a and 2.0b) include support for HDR.
HDMI 2.1: Supports up to 10K resolution at 120Hz, as well as improved HDR with dynamic metadata and enhanced Audio Return Channel (eARC) which allows sending Dolby Atmos and DTS:X audio from the display to a receiver. HDMI 2.1 includes variable refresh rate like FreeSync, though some HDMI 2.0 monitors also support the feature. A newer version (HDMI 2.1a) adds Source-Based Tone Mapping(Opens in a new window) (SBTM).
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
DisplayPort 2.0: Supports 16K with HDR at 60Hz and 10K without HDR at 80Hz. A new DisplayPort 2.1 replaces this version and adds USB4 compatibility.

DP 2.0 configuration examples
With the increased bandwidth enabled by DisplayPort 2.0, VESA offers a high degree of
versatility and configurations for higher display resolutions and refresh rates.
In addition to the above-mentioned 8K resolution at 60 Hz with HDR support, UHBR20
through USB-C as DisplayPort Alt Mode enables a variety of high-performance
configurations:
Single display resolutions
One 16K (15360 × 8640) display @ 60 Hz with 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (with DSC)
One 10K (10240 × 4320) display @ 60 Hz and 8 bpc (24 bit/px, SDR)
RGB/Y′CBCR 4:4:4 color (uncompressed)
- Dual display resolutions
Two 8K (7680 × 4320) displays @ 120 Hz and 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (with DSC)
Two 4K (3840 × 2160) displays @ 144 Hz and 8 bpc (24 bit/px, SDR)
RGB/Y′CBCR 4:4:4 color (uncompressed)
-
Triple display resolutions
Three 10K (10240 × 4320) displays @ 60 Hz and 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (with DSC) -
Three 4K (3840 × 2160) displays @ 90 Hz and 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (uncompressed)
When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous
SuperSpeed USB data and video, DP 2.0 can enable such configurations as:
-
Three 4K (3840 × 2160) displays @ 144 Hz and 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (with DSC) -
Two 4K × 4K (4096 × 4096) displays (for AR/VR headsets) @ 120 Hz and 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (with DSC) -
Three QHD (2560 × 1440) @ 120 Hz and 8 bpc (24 bit/px, SDR)
RGB/Y′CBCR 4:4:4 color (uncompressed) -
One 8K (7680 × 4320) display @ 30 Hz and 10 bpc (30 bit/px, HDR)
RGB/Y′CBCR 4:4:4 color (uncompressed)
