LUOM LJ-DP16K DisplayPort 2.1 cable

This 3.3 ft DisplayPort 2.1 cable connects a graphics card to a monitor using male-to-male connectors. It is built with 28AWG oxygen-free copper conductors and triple shielding for signal integrity. The cable is rated for 40 Gbps bandwidth under the HBR10 specification. It suits PC builders and gamers who need a short, high-bandwidth link for 8K or high-refresh-rate displays.

Suits 8K 60 Hz and 4K 144 Hz setups.

The cable supports 8K at 60 Hz, 4K at 144 Hz or 120 Hz, and 2K at 240 Hz or 165 Hz with DSC, FEC and HDR10. It works with G-Sync and FreeSync for tear-free gaming. Backwards compatibility covers DisplayPort 2.0, 1.4, 1.3, 1.2 and 1.1 devices. Buyers who need a cable longer than 3.3 ft or who require USB-C or HDMI connectors should look at a different product.

40 Gbps headroom handles 8K 60 Hz and 4K 240 Hz DSC

The 40 Gbps link comfortably carries 7680 x 4320 at 60 Hz, 4096 x 2160 at 240 Hz with DSC, and 2560 x 1440 at 240 Hz. It also supports 16K at 30 Hz and 10K at 30 Hz with DSC, plus dual-screen 8K at 120 Hz. Uncompressed 7.1 and 5.1 audio pass-through is included. The 3.3 ft length keeps attenuation low, but the fixed short reach limits use to desktop-distance connections.

Questions about this item

What graphics-card outputs are required to use the LUOM LJ-DP16K DisplayPort 2.1 cable?

The cable needs a DisplayPort 2.1 source; it also works with DisplayPort 2.0, 1.4, 1.3, 1.2 and 1.1 outputs on cards such as GTX 980, GTX 1080, Radeon R9 290 or HD Graphics 4600.

Will the cable run at full speed if I keep an older DisplayPort 1.2 monitor?

The cable is backwards compatible with DisplayPort 1.2, so it will carry 4K at 60 Hz or 2K at 144 Hz, but the 40 Gbps HBR10 bandwidth and 8K at 60 Hz require a DisplayPort 2.1 display.

How can I confirm the cable is delivering 8K at 60 Hz after connecting it?

Check the monitor OSD or GPU control panel to verify the active resolution reads 7680 x 4320 at 60 Hz and that HDR10 or G-Sync indicators are enabled.
