Question: Does it work with a VGA to HDMI converter?  What model/brand do you use?
Document: Delivers all they features and more. There were several little glitches I had to work through. One of which not realizing how important the USB cable is to livstream. The cable must be connected to Livestream. After working through the issues I later found that he upgraded model must be purchased to use some much needed features.
Note that the USB 3.0 feature will only work on Windows machines equipped with USB 3.0 capabilities.Wireless HDMI extenders should work well with this provided they can output a 1080i or 720p signal. I haven't experimented with that yet but I do have a Phillips model I'm going to play with.
I've had this unit since it first became available. It works perfectly. It is entirely digital. HDMI and SDI inputs are outstanding. You must use digital audio and the video inputs must be the same resolution, but why would anyone use video at a resolution other than 1080p/i? If you want analog audio and mixed video resolutions get the higher model ATEM or a Tricaster at $5,000+. I've also done many installations using ATEM Television Studio.
So now it's possible to forgo the analog to digital converter and run your mics directly through one of your cameras or anything else that can output audio through HDMI.
This product is not what they say it is. its a simple scam  that sucks the people that want to stream and record to purchase additional hardware not specified in the description. i bought this for my church hopping to finally record and stream but what i found was the exact opposite!!!! they force you to purchase a converter for audio be it SDI or HDMI. no way around it which cost and additional 200 dollars.
We purchased the ATEM television studio to record the Sunday services at church and so far it has performed exceedingly well. This product is definitively the right choice for any small multi-camera (up to 6 cameras at a time) production. There are just three design deficiencies that you may want to keep in mind when thinking about using this product: 1- The device will not work with most HDMI cables, connecting it to a camera, that are longer than ~18ft.
Apparently, tech support had never seen this problem. Mine was an HP laptop.My 2nd problem was that the HDMI inputs were not compatible with 3 of my VGA-to-HDMI converters -- a major flaw for those needing to record output from a laptop computer. I could not overcome this. In the end, because of this problem, I had to return the unit. As a consumer/pro crossover device, it's really got to support a multitude of HDMI devices.
tons more gear than a switcher. If you want more flexibility try spending 10 times more cash. We are thrilled. Our Cameras have very long cable runs so we use HDMI to Component Video converters  for the cable runs and then reconvert to hdmi at the switcher. Audio is mixed on a Mackie 1604 vlz pro with the tape out going to the component to hdmi adapter's audio input.
We never put it in a rack but simply placed in on a desk and it worked fine. It was thrown around a bit and the aluminum construction held up fine. We had a few power surges and outages and the TV Studio powered right back up. We use Canon HF G20 and G30 camcorders via HDMI and HD-SDI cables into the TV Studio, then we have the Black Magic mini-Recorder via thunderbolt into our Mac, and then we broadcast live via Ustream.
This thing gets extremely hot! It's too hot to touch! It comes with a heatsink mounted on the rear but it seems like it needs some fans. I only have 4 cameras connected. It's always hot regardless of what I'm doing.2. The other issue is that it is VERY picky about HDMI signals. Any HDMI cable longer than 8ft WILL NOT WORK when connected to one of the inputs. I was forced to use a cheap powered HDMI signal booster on all of the input cables. This worked perfectly.
Answer: Hi again, you should take a look for VGA - DVI scalers.  From there convert the DVI to HDMI. For example, Gefen makes a VGA-DVI Scaler Plus, or Extron makes a RGB-DVI 300(?).  The key is to be able to scale the popular 1920x1200 output from your projector to 1920 x 1080.
