You need a 4K display. Your PC's DisplayPort doesn't speak dual-mode (DP++), so a passive adapter just gives you a blank screen or a weird colour shift.
The ATEN VC986 is an active adapter. It runs its own conversion chip, which means it handles the signal translation properly even when your source card can't do it natively. Mini DisplayPort or full-size DisplayPort in, HDMI out to your 4K TV, monitor, or projector.
No driver installs. No external power brick. You plug it in, the chip does the heavy lifting, and your 4K panel lights up. If you've been stuck at 1080p because your GPU just won't handshake with a passive dongle, this is the fix
