vienon HDMI Dummy Plug (4K UHD), 3 Pack Headless Ghost Adapter, Virtual Monitor Display Emulator New Generation Compatible with Windows Mac OSX Linux Support 4K/2K/1080P Multiple Resolutions

Good product

I bought this to use my new Mac Studio "headless" with remote screen sharing. This is a silly way to use a computer like that, but worked great for a week or two while I was migrating over from the MacBook Pro that I was replacing.This HDMI dongle exposes pretty much *ALL* the resolution possibilities, which was actually pretty amusing. The ultimate in "Multi-sync" (virtual) monitor capabilities!Great prices, does what it says. Now I just need to find a place to store this until the next time I need to use it without it getting lost and disappearing to the same place that socks vanish to from the clothes drying. It's pretty small, but effective.

This product is not as advertised. They are only 1080p not 4k. Also only came with 2 not 3. And don’t light up as in photo. If you need 4k then avoid these.

This actually resolved a remote resolution issue I had on a headless machine and using any desk. Plugged this in, and problem solved.

These work great for my uses. I admin 12+ machines I need to be able to log into remotely. Without these attached, I just got a blackscreen. WITH these attached, it thinks theres an actual monitor attached and am able to remote in just fine, do what I need to do then disconnect. Not sure how long they will last, but I've had at least 6 of these deployed for the last few months without issue. Huzzah for things that just 'work'!
