You've got a monitor two metres away and the cable you're using can't keep up — resolution's capped, colours look washed out, or the second screen just won't handshake. A longer run shouldn't mean a lower spec.
This ATEN 3 m DisplayPort cable runs DP 1.4 at HBR3 (32.4 Gbps), which opens up 8K (7680 × 4320 @ 60 Hz) and crystal-clear 4K UHD (3840 × 2160 @ 60 Hz). Multi-Stream Transport means you can drive two monitors from one port in mirror or extended mode without a dock.
Whether it's bridging a workstation to an external display across a desk or feeding a conference-room panel, plug it in and the handshake is done. No drivers, no settings menu.
