gofancoProphecy HDMI EDID Emulator Programmer – EDID Programming of gofanco PRO-EDID Emulators, 5 Pre-Defined EDIDs, Custom EDIDs, USB Bus-Powered, Windows only, TAA Compliant (PRO-EDIDwriter)

I use a gaming PC in the basement to run games and stream them over Ethernet to whichever room I feel like playing in at the time. The downside to this is the TV connected to the gaming PC is a few years old and doesn't support HDR. Thankfully, display emulators like this stick exist and pretty much eliminate any issues running Windows headless may have.The original EDID configured on the stick was not quite what I needed to use with my monitor. I did not want to buy the additional gofanco EDID programming tool, so I tried the freely available Custom Resolution Utility. This works great for my purposes. I was able to clone the EDID info from my primary monitor and load it onto the emulator stick. Now Windows has unlocked the HDR options and streamed games look great.

We have 2 of those in service and are adding a 3rd, plugged into KVM switches. Their true uniqueness is that they're programmable. I took a while to learn EDID and find a programming tool that did what I needed it to do, but it's been working great and allows us to "fool" downstream computers (Macs) about having all the resolutions and refresh rates we need. Of course if your connected monitor can stomach these EDID settings, it will also display them.

I use an Nvidia Shield to stream games to my TV some times. Unless I have an HDMI cable plugged directly to my TV, I can't enable HDR because none of my monitors at my desk support 4k resolution. This is a known issue but now just plugging in this device in my GPU's HDMI port, my PC and Shield thinks I'm connected to a 4k display so allows me to enable HDR. Best 20 bucks I've ever spent! Well, except that time down in.... eh, another time lol.One thing that is a possible concern but not sure yet is I don't connect any monitors to the emulator as I've heard sending HDR to a monitor that doesn't support it may damage it. So when I stream to the TV, just unplug that monitor connected via HDMI and slip this device in and I'm golden. Maybe I can put my cheap AMD graphics card in and keep it plugged into that so I don't have to keep switching cables out. I'll have to test.

Does spoof edid data, so that much is correct. The device also advertises to the attached computer all the listed resolutions. If you select them though, the output video is still at 16:10 aspect ratio, just sort of squished or with bars. It might be some combination of the OS and GPU drivers attempting to make the listed resolutions work for the supposed 16:10 display that they think is attached, but it means that for widows at least, this wont really work for standard 16:9 displays. Ive tested it with 1680x1050 monitor, which was the one I intended on using(keeping the kvm from reshuffling the attached windows), and a 1920x1080 display to test if the issue was monitor/cable specific(it wasnt).

I obtained this 4K EDID passthrough adapter to help a Mac Mini M1 work with an AVR and projector.Although, it indeed made it easy to achieve stable 4K 60Hz output, streaming services would not display video. Hours later I notice the tiny lettering in this device's photos that indicate it does not pass DHCP signals. Renders it nearly useless in a home theater setting.Were it to return a HDCP signal it would be a perfect device for making PC's compatible with HT devices. Unfortunately it can only create a video chain that reports zero HDCP capability. Hence, streaming services fail due to this adapter.

I bought this for my steam deck - game mode doesn't allow adjusting the display resolution currently, and my TV would output 4096*2160 24hz. This caused awful input lag too.At first I got no signal or audio, almost returned it. However, I use a reciever and 5.1 setup. Since this does not pass hdcp signal, it won't work in line with recievers. Direct plugging to my tv from the decks dock fixed the issue - then I use HDMI ARC for audio thru the reciever.Gladly playing at 1080p now. Woo!

Windows 11 PC to 4K/HDR display. Works great with Netflix 4k without this dongle, but as soon as i insert the dongle, it fails to do HDCP 2.2 (see in edge browser, edge://gpu), so no Netflix 4k. Or AppleTV - or any other 4K streaming ;-(I also have the Gofanco EDID tester, https://www.amazon.com/dp/B07SSD8VR8, which works properly, but is much more expensive, needs an adapter cable and is bulky.Why, Gofanco ?? This is such a basic requirement.

When I bought this thing I did expect its female-to-male passthrough design can let me directly plug my monitor to its female side, then plug this thing into my Mac, so that I can save one HDMI port while letting HiDPI work. However, my idea is wrong, since by using this the Mac outputs 4K signal to my monitor, and my monitor doesn't accept this. By contacting the seller they gave this convincing answer. I now use it as a dummy 4K adaptor for my Mac to enable HiDPI for my 2K monitor and it works well.
