  • This review pertains to products I purchased from Muxlab through B&H Photo. Both of these vendors were very gracious in their help when I was ‘under the gun’ to produce an event for 500 people. The Event was last April, and the product orders placed between mid March and April, 2015. The part of the project that pertains has to do with projecting a live video stream of a ‘presenter’ through a VGA projector without latency. The video camera (Sony HDR CX-160) was about 80’ line of sight to the stage and sent it’s HDMI signal to the ‘Source Side’ of a Muxlab 500450 rev B HDMI Mono Extender Kit. I am using the extender with 200’ of high quality Cat 5 terminating in the ‘Display Side’ HDMI Extender.
    In this video review please note that the 200’ of Cat 5 is coiled and laying near and on live 120 v elect power.
    The first video scene shows the set up; the camera is looking at some musical instruments hanging on the wall in my office area. The camera is connected exactly as described above. In this scene the video source exits the HDMI Extender from the HDMI Out which is directly connected to a Muxlab HDMI to VGA Converter (Muxlab 500466) which is connected to a 24” high quality VGA cable, that is connected to a high end Casio 3,500 Lumin VGA projector.
    As you can see on the projection screen the video image is very dirty with what appears to be a lot of noise. While ‘latency’ was not an issue, the projected image was. The image I got of the presenter at the event was nearly as dirty as the one you are seeing on the screen now.
    However, since this was the result, I have steered away from attempting to provide live video streaming as part of my services. With that said last month a person that handles AV for a large church volunteered to help me at an event his wife was attending and the topic of video streaming came up - I wanted to know what they did at that large church to make their streaming to screen work while mine did not. He came over to my house to work on the setup when we discovered more data that I want to share with you in the hope that you may have a different solution.
    We performed everything as I described to you previously. After which I disconnected the Muxlab HDMI to VGA Converter and instead connected a 40” Proscan TV Monitor directly to the VGA output. As you can see the results are perfect!
    To prove the VGA / projector combination provides clean images next I connected the VGA projector to the computer through a Kramer VGA switcher playing a video stream so you can see the VGA projection of the set up is not part of the problem.
    It appears that the Muxlab HDMI to VGA Converter is the problem.
