LUOM TJ-A038 DP 1.4 Dual Video Switch
The LUOM TJ-A038 takes a single DisplayPort 1.4 source and sends identical or extended images to one DisplayPort 1.4 display and one HDMI 2.1 display simultaneously. It suits professionals driving a monitor and a projector, or gamers who want a high-refresh panel alongside a living-room TV.
Plug-and-play with mandatory USB power
Connect the included USB power cable before linking any video cables; the switch will not pass a signal without external 5 V. Use certified DP 1.4 and HDMI 2.1 cables rated for 32.4 Gbps, otherwise 8K 30 Hz or 4K 120 Hz modes may fall back to lower refresh rates. MST extended-desktop mode limits both outputs to 4K 60 Hz combined.
Check your GPU and cables before ordering
Your graphics card must support DisplayPort 1.4 MST for extended mode; SST mirror mode works on any DP 1.0–1.4 port. HDMI output does not support 1440p 165 Hz or 144 Hz — those rates are DisplayPort-only. Verify that your monitor, TV and operating system (Windows, macOS, Linux, Android, iOS) each list the target resolution and refresh rate in their specifications.
