CompuLab Fit-Headless (GS) HDMI 2.0 Adapter, Supports 4K@60Hz, 1080p@120Hz, 7.1 Channel Audio, Ideal for Game Streaming, VR Headset Compatible

Saved me so many times.

I have a home theater receiver set up with surround sound for the desktop PC. If you're here there is a pretty good chance that you know the only really good way to make that connection digitally (that is, without multiple analog cables) is HDMI. TOSLINK/Optical "works", but you have to get a sound card with DTS encoding to get surround from non-movie sources! (NOT CHEAP)Now, the gotcha is that you can't do audio only HDMI... so you need to connect the HDMI from the PC to the receiver and then to the monitor. Which is fine.... IF you only have a 60Hz monitor because that's all the cheap HDMI receiver port will do! So you go get a headless instead so you can run your DisplayPort connected 144Hz screen... except that now you have a "dead" monitor off to the side if you mouse over too far and you can lose open windows on it. Annoying. Well, you can just mirror one screen with the headless right? Well, if you have an NVIDIA graphics card you can't have different refresh rates on mirrored screen! Cheap headless dongles will only let you go to 60Hz or less, so you still have the same problem you started with!So now, this is where this bad boy comes in. I was able to set the headless to 1080p and 144Hz and mirror it with one of my screens! The spec says it only goes to 120Hz and figured that was better than 60Hz, but no, she goes to the full 144Hz! I've been running it this way for a few months now, no issue. This is literally one of the only dongles on amazon that even claims 120Hz (much less delivers 144Hz). If you are trying to connect HDMI surround sound audio and you don't have potato screens YOU WANT THIS.

Fantastic! This was exactly what I needed for steam streaming. I'm able to plug this in to the hdmi port of my gtx 1080, while my gsync display sits on the displayport. This allows me a full 3840x2160@60Hz, the full resolution and refresh rate of my 4k for streaming.I had originally purchased the fit-headless 4k, since the description (inaccurately, in my opinion) states that it will do 4k at "high frame rates", but in reality that adapter only does 4k@15Hz, hardly high frame rate. The GS model provides a full 60Hz, and it works flawlessly.Here's a useful tip for using this product with a non-headless steam streaming box (i.e. one where you will play on a local monitor as well as streaming). If you launch steam in big picture, in the settings menu you can specify which monitor to use for big picture, and this can be different from your normal primary monitor. As a result, if you do not use big picture when playing locally on your primary monitor, you can tell big picture to use the "monitor" provided by the fit-headless GS, and it will automatically switch primary monitors for you when you enter big picture mode, and automatically switch back when you leave. Since steam streaming will launch big picture on the host when you start streaming, you can use this to enable different resolutions for streaming that might not be available locally (in my case, a 4k for streaming in the living room, vs a 3440x1440 ultrawide on the desk). Now if I could just get steam to start games at appropriate resolutions depending on whether I'm local or streaming, I'm golden.

At some resolutions, such as 1440p, you only have the option of running at 120Hz. Not particularly great if you have 60 Hz monitors and you don't want to unnecessarily stress your blower-cooled guest GPU.Apparently, on a Q&A for the fit-Headless 4K, someone asked if 1440@60 was possible, and CompuLab replied that for this combination you would need this specific adapter, which is false. On my fit-Headless (GS) ordered in 2022, for 1440p I am only given the option of 120 Hz by Windows. Either they do not know what their product is supposed to do or they are lying, and I am greatly confused about why either case would be true.

Bought this to use for a Windows gaming VM with an Nvidia GPU using Sunshine and Moonlight. Doesn’t work, despite this being the single Sunshine recommends. Didn’t detect it at all no matter which HDMI port I use on the GPU.

What can I say. Ice purchased 2 of these over the years. The first was for a windows gaming PC that I essentially used to stream games to my phone. I wanted to be able to set a specific resolution and keep it that way. This allowed me to do that. I rarely ever had that PC hooked to a monitor or TV and instead managed the whole thing via remote desktop software.The second I purchased was for a Mac Mini that I was using as a blue bubbles server. I wanted to set my Mac mini to output a 16:10 resolution as that's what my Samsung tablet is and that's what I use to access the Mac for maintenance and updates. Works like a charm.

The CompuLab fit-Headless (GS) works perfectly for me. I just plugged it into the HDMI port of the graphics card on my headless computer, then connected to that computer using a remote desktop programs on another PC. I could easily change the resolution in the system settings. Also, the fit-Headless GS is recognized as a speaker in the sound control panel, so I could select it as a sound output device and get audio over my remote desktop connection.My graphics card has a maximum output resolution of 3840 x 2160, so I wasn't able to test whether the CompuLab device supports even higher resolutions (but other reviewers have indicated it supports 4096 x 2160). Here are the resolution options it gives me, as limited by my graphics card:3840 x 21603840 x 16203440 x 14403200 x 18002560 x 14402160 x 12002048 x 15361920 x 12001920 x 10801680 x 10501600 x 12001600 x 9001400 x 10501368 x 7691360 x 7651280 x 10241280 x 7681280 x 7201152 x 8721024 x 7681024 x 600832 x 624800 x 600

Good performance for my i7 Mac mini, but inverts rendered text on Sketchup 2017. Best case, it’s a 90% solution.
