ATEN VC081A True 4K HDMI EDID Emulator Adapter – Stable 4K Handshake with Learn Button

Your 4K display and source keep losing sync. Blank screen, flicker, or the resolution drops to 1080p mid-presentation. The VC081A is a compact True 4K HDMI EDID emulator that learns your display's profile with one button press and holds it steady for the source. Push the Learn Button, the LED confirms the grab, and from then on your PC or server gets a consistent handshake every time it boots. Handles up to 3840x2160 at 60Hz in 4:4:4 colour. HDCP 2.2 compliant, 3D and Deep Colour pass-through. A handy trick: keep it in the chain on a server or PC you access over IP so the machine stays awake without a monitor attached. Powered straight from the HDMI source — no extra cable. Plug it in, press the button, sorted
