SKU CH-K2HP-X4FZE MPN 40948

Connects a DisplayPort 1.4 source to an HDMI 2.1 display at up to 8K 60 Hz or 4K 144 Hz with 48 Gbps bandwidth and external Type-C power

  • 8K resolution at 60 Hz with 48 Gbps bandwidth
  • 4K gaming at 144 Hz via DisplayPort 1.4 to HDMI 2.1
  • Lossless 7.1-channel audio syncs automatically with video
  • RTD2173 chip prevents stutter and ghosting on long runs
  • USB-C power port keeps 20 cm cable stable over distance

DP 1.4 to HDMI 2.1 adapter 20cm

This Enfain 40948 adapter converts a DisplayPort 1.4 source to an HDMI 2.1 input. It suits desktop users connecting a graphics card to a high-resolution monitor, TV or projector. The 20cm cable includes a USB Type-C power lead for stable long-distance signal transmission. External power is required for operation.

Bandwidth caps at 48Gbps with 8K60 or 4K144

The link supports a total bandwidth of 48Gbps. Maximum output reaches 7680x4320 at 60Hz, 3840x2160 at 144Hz or 2560x1440 at 144Hz. Higher refresh rates at 8K or uncompressed 8K above 60Hz exceed the interface limit. The 1.4 protocol on the source side also bounds the maximum throughput.

RTD2173 chip enables 7.1 lossless audio

The built-in RTD2173 processor handles video conversion and audio extraction simultaneously. It delivers synchronised (DTS-HD) 7.1-channel surround and stereo without quality loss. Buyers needing only basic stereo pass-through or a purely passive dongle will find the active chip and mandatory power connection unnecessary.

Questions about this item

How do I choose between the 8K 60 Hz and 4K 144 Hz modes on the Enfain 40948 adapter?

The adapter supports both 8K at 60 Hz and 4K at 144 Hz; pick 8K 60 Hz for maximum desktop resolution or 4K 144 Hz for high-refresh gaming, matching your monitor's native capability.

What does the 48 Gbps total bandwidth mean when I connect this adapter to my graphics card?

The 48 Gbps bandwidth carries uncompressed 8K 60 Hz or 4K 144 Hz video plus 7.1-channel audio through the RTD2173 chip, so the link will not compress or drop frames at those rates.

How do the DisplayPort 1.4 input and HDMI 2.1 output limit what resolutions and refresh rates I can actually use?

The DP 1.4 source and HDMI 2.1 sink combine to allow 8K 60 Hz, 4K 144 Hz, or 2K 144 Hz; any higher resolution or refresh rate is blocked by the 48 Gbps link ceiling.
