Most inexpensive HDMI to VGA supporters lack any kind of support for video standards conversion. Which means that they will only work if the HDMI video input signal is in a video format (resolution, frame rate, and color space) that the monitor can display.
The issue with many VGA monitors is that they do not have a native 16:9 aspect ratio. Many are 4:3, or 16:10, or some other aspect ratio. And even if you have a VGA monitor that is 16:9, many are not actually 1920x1080 as there were a lot of computer displays made with non-broadcast standard resolutions such as 1366x768.
The second issue is that VGA signals typically use the RGB color space whereas the ATEM switchers use the YUV color space (also referred to as YCbCr) which is more common in broadcast applications.
You can sometimes get inexpensive HDMI to VGA converters to work with the HDMI output from a computer as computer video cards usually output RGB signals and are capable of outputting a wide range of resolutions and aspect ratios. But the ATEM Minis only output 1920x1080 (1080p) video resolutions.
So you would likely need an HDMI to VGA converter that includes video scaling and color space conversion capabilities to get the ATEM Mini output to work with a VGA display. Such video scaler converters do exist, but they are quite a bit more expensive than the basic HDMI to VGA models (often costing a couple hundred dollars or so).
And since you can get an LCD monitor with a direct HDMI input for around $100 or so these days, I tend to agree with Sander that this is likely a better option. It will be less expensive and give you better video quality than a VGA monitor would.
