HDMI 2.0 4K EDID Emulator (Model: HD-EWB), Support Exact EDID Copy and Emulation, HDCP Passthrough (not Bypass or Remove), PreSET EDID is 1080p@60Hz 4:4:4 and 4K@60Hz 4:2:0 with 2.1CH Audio

Well this thing works like a charm! So easy. So, soooo easy! Thank you makers of the HD-EWB. The THWT HD-EWB works perfect on all but my LG monitor. But I did get it to work so-so, and good enough to make me happy enough to not get bent out of shape. Its a slight delay after doing a copy of the EDID. Something is very wonky with the LG monitor so I'm not at all irritated. I still think there is a way for me to fix it based on the chain where I connect it. Anyway I will figure that out later, or at least play around with it. For now I am happy. It even works well with 4 and 5 HDMI port switches. One of my switches even has an automatic source detection and switch over based on live/dormant signals. To get that to work on that 4 port auto detect/switch HDMI switch(which I really didnt even have to play around with because I got it dont on the first try) was this: First make sure all monitors are plugged in and WORK. Then Unplug all monitors from it(simply unplug the HDMI cord from the port on the switch) with exception of the target monitor to you want to setup first(it can be in any of the ports first). Then simply unplug that from the port in the switch and plug in the emulator. Then plug that emulator into that HDMI port you just unplugged from. Wait for it to turn green and display signal, then plug the next emulator onto the HDMI cord and plug that one into the target HDMI port on the switch, wait and it will turn green. Then do it for the next, and next.... Then test it by selecting each source and it works perfectly: IMMEDIATELY and SEAMLESSLY - QUICKLY! This really is a great product! I actually couldn't believe it when it happened. And btw, my setup is 2 laptops using a separate USB-C docking station and 3 monitors: 2 Acer's, and 1 LG. On one of my laptops I had to use the VGA port on the USB-C docking station because I only had 2 HDMI out ports on it.... So I plugged in a VGA to HDMI converter and then plugged the HDMI cable into it that converter, and then plugged the emulator on the other end of the HDMI cable, then plugged that into my 4 port HDMI auto-switch - this too was immediately accepted and worked perfectly. So basically anything I threw at these emulators worked(with exception of this pesky LG monitor). I just ordered 4 more of these THWT HD-EWB emulators last night.

I really wish this worked. You can program it/set it and then after a complete power down of the PC and monitor, the device just won't power up next time you power on everything. It flashes a dim blue LED. you end up having to unplug it and wait a few minutes and can plug it in after a few minutes and it'll start to work. Completely defeats the purpose of using it as a keep alive device if you have to manually reconnect it every single time. If power is an issue, maybe using a USB cable to power it like some older VGA to HDMI adapters would be a good approach for fixing this issue.

I'm using these little gems everywhere and all have worked perfectly, especially since it can learn the resolution parameters to replicate. Now when turn off my monitors at night, Windows does not rearrange everything. When I get started in the morning, everything was as it was. The only observation I might touch on is that when plugged into a device, a monitor in particular, many have the button facing the monitor where I could not activate it. My solution is to get the best short extension cable available and use that to allow access to the button, then remove the extension and plug in the EDID emulator into the monitor. I don't know what the perfect solution would be... a button on the side, but then which side? Two buttons? Anyhow, aside from that, these are performing as expected and truly made my life a little bit better.

First and foremost this is one of the easiest EDID emulators I've used to get EXACTLY what I wanted. The biggest feature for me being that it will also duplicate your audio information making it completely seamless for your setup. So if you're struggling to get any other emulator working for your exact setup I recommend giving this one a shot! If you're on the fence and would like more context then read on. I've been streaming games from my PC to various devices for more than 8 years now with wildly different setups and various degrees of success. My current setup is my gaming PC in the living room directly connected to a surround sound amplifier and my TV primarily to directly use it there. Secondarily it is also in the living room for wired room scale VR. And lastly to stream games when I either want to use the ultra-wide monitor, keyboard and mouse at my desk in my office or on a mobile device away from home. You can imagine this creates some conflicts with the wide variety of uses and devices. From different displays and different audio outputs used along with PCs having generally random quirks when dealing with all of these situations at once. Just having the living room TV turn on or off while streaming will change the available displays and completely kill a stream, let alone needing to switch resolutions between devices. I've used about 10 different Virtual Display/EDID solutions and this one has been the only one to just do exactly what I needed with the smallest of fuss. All of the other kinds of devices you'll find will act like nothing more than its own display including a limited number of options for resolutions, refresh rates and audio outputs. Most of them (expect for the ones with toggle-able switches) have only ever supported 2.0 stereo output. This isn't a big deal if you're running the system completely headless (without a real screen attached) and will always be streaming to another device as the stream software usually creates a virtual sound output that can support surround sound. But if you also want to use this system directly (pass-through or not) this will become a conflict you'll constantly need to manage. I've always struggled finding a device that'll support anything I need between 1080p to 4K (including ultra-wide resolutions), 60hz to 144hz and stereo to 7.1 surround sound. They all have random mixes of these but most revolve around what you'd find with a typical TV and that also includes only stereo sound. Some (usually more expensive) EDID pass-through emulators will support different sound outputs using toggle switches but they are still limited out of the box to what ever is already programmed so if it doesn't exactly match your setup you usually need to make compromises. Even fewer will let you modify the built-in EDID profile with whatever you want but this is usually risky using flashing tools and you need to know what you're doing to not brick the device. Finally... This one device solved all of this for me. Once you plug it in you hold the button to clone what ever EDID information is currently available and that's it, your PC will always see that snapshot as being available regardless of what's connected. Not only did this ensure I could use it in my living room as-is but also meant that any changes on the output, such as the TV being turned off, didn't mess with my displays while streaming. This also means any modification to your supported outputs through software (such as with the Nvidia Control Panel or CRU) will get cloned and supported even if your attached device doesn't, effectively modifying the EDID without needing risk flashing it! I was able to add the 3440x1440 resolution needed for my desk monitor even though that obviously is not something my TV supports. The cherry on top is the fact it does have a hard-coded built in EDID that works great as a fail-safe! Multiple times I've had something go wrong where the resolution doesn't switch back to one my TV supports so when I turn on my PC nothing gets displayed and I can't fix it without streaming to the last device again and manually changing it. Now I can press the button at the PC to fall back to 1080p to gain access to the desktop on the TV, change the settings within range of the TV before switching back to my normal EDID. The only issue I had with this, which is why it won't get 5 stars, is it took me a couple of tries to clone the EDID and it didn't seem to want to work at first. It doesn't quite match the "manual" and some parts of it are too vague but I was eventually able to get it working after a couple of attempts.

過去にHDMI切替器を使ったところ、切替器で非選択状態になったHDMIポートはパソコンもしくはHDMIアダプタ側からは液晶モニターなどの対象HDMI機器の存在を検出できなくなるため、マルチモニターの場合は切替器の選択状態に応じてシングルモニターになったりマルチモニターになったり都度切り替わるためストレスに感じていました。 EDIDのキーワードにヒットするHDMI切替器を購入してみても安価なHDMI切替器では謳い文句にはあっても実際にEDID機能が搭載されていないようで半ばあきらめていたけれど、単体のEDIDエミュレータの存在を知ったため注文。 この商品は、HDMI切替器で液晶モニターへ画面出力した状態で商品に付いているボタンを押すことでエミュレートモードになり、この状態だとHDMI切替器で非選択状態にしてもパソコン側からは液晶モニターが疑似的に存在しているように見え、シングルモニター・マルチモニターがHDMI切替器の状態に依存せず常にマルチモニターとして画面出力している状態を維持することが出来るようです。 切替器の状態によりマルチモニター側のウィンドウが都度メインモニターに戻ってきたりサブモニター側に移ったりと言う気持ち悪い動作が改善できたため大満足。 必要なHDMI切替器のポートにはこの商品を使おうと思います。

Stopped my old Tivo from resetting to default resolution when the TV turned the soundbar off. A little expensive but it seems to work.

Apple Silicon M-series Macs seem to have an EDID timing issue with HDMI extenders - using this device completely worked around the issue. The computer sees as if the screen is always connected, and the EDID emulator to HDMI extender was solid. Simple to use, and didn't trigger an issue with incorrect colour space that a different preset device had. I'm using with an M4 Mac mini that couldn't get a stable connection to 2 professional HDMI extenders when directly connected. With these EDID emulators, instant stable connection. Ran a test system for several weeks straight to test reliability - no hiccups or output issues seen. Because if you have this connected on the computer end, the computer always sees the display device as connected, it works great with KVMs as well (no re-detection of display) or if you completely unplug a monitor or projector.

I bought 2 of these. One for a TV I'm using as a monitor that would cause Windows to move all my applications back to the Laptop screen when the TV went off due to the power saving signal sent to it by Windows. Now that doesn't happen because it thinks the EDID emulator adapter is an actual screen so Windows doesn't freak out and move all the applications back to screen 1 when things go to sleep. The second one I'm using on my Shaw-Direct Satellite receiver box and an older flat-screen TV that would lose the audio sync signal when skipping ahead in a recording. So then I'd have to turn the TV off and back on again to get the audio to come back. Now this doesn't happen. I had bought a different brand EDID Emulator adapter before this one but it wouldn't pass through the HDCP signal like it claimed it would so my Satellite Receiver wouldn't work with it and would disable the picture until it was removed, but NOT this Adapter. It passed through the HDCP no problem like it said would. Just plug these adapters into the source of your HDMI signal, and then plug the other end into the cable feeding your TV/Display. It should work in "Green" mode displayed on the LED bubble. If it doesn't press the button on the bottom to turn it to "Blue" mode on the LED bubble and it will work.

二画面で使っている途中で別の入力に切り替えると画面が一画面になってしまうのを防げる目的は果たせました。しかし、使ってないときにキーンと耳なりのような音がずっとしていて不快です。使わないときは外してます。これは面倒。不良なら変えてほしい。
