Microh console software LED video wall

As the Microh company that was making some LED video wall products isn’t in business anymore and that i myself needed some quick information one day about how to use the system, here’s everything i learned from a colleague at work including the software that was supplied with the rental system we had.

Hope it can help you also.

Product specifications:

Real world setup mindset

Since each panels have a 80×80 pixel resolution, if we have 5×3 modules, the effective work resolution will be 400 x 240 px. Now, since we are always dealing with odd end resolutions depending on which panels arrangement we use on each venue, a video scaler (LED Video Processor) is necessary to ensure that the video resolution and frame rate provided to the wall is independent from the source ( laptop or video mixer).

On the venue i worked, the video scaler used was LVP605S (manual software) with an integrated LED transmission card accessible on the rear panel. A physical jumper (dvi) was making a link between the scaler and the transmission card.

480p YouTube       1080p,60          1080p,60       1080 to 400×240         400×240 into 15 blocks of 80×80

Video player  –>   Laptop(s) –> Video mixer   –>   Video scaler     –>     LED Transmission card / box

upscale resize   –>       1:1          –>            1:1          –>   downscale resize

Not sure yet of this but i can presume that, if you want to configure a custom resolution ( if your graphic cards permit it), you could output directly from your computer or your video mixer the final resolution of your wall into the LED transmission card. This way, less resizing will be applied to your picture, resulting in a much sharper picture.

Remember that, each time an image is resized (using a resize filter) the quality gets lowered.

The first resizing usually occurs in the image or video player software, as the file played on a computer is mostly never EXACTLY the same as the output resolution of the computer itself. If you play a 1080p file on a computer outputting a 1080p resolution, in this case, when played in full screen ( not just maximized), the player should understand that no resizing is necessary and forward each input pixel to each corresponding output pixels.

After that, the picture gets to the video mixer, where if properly configured, should input and output the same video resolutions. laptop and camera settings has to be adjusted so everything matches.

Then, it reaches the video scaler where it gets resized to suite the needs from the led transmission card, in our situation, 920×1080 gets resized to 400×240.

Since on a live venue, it is mostly possible that you will need to play some video of other size than 1080p, the player will need to process a first upscale resize while the video scaler will have to apply a downscale resize to the final 400×240.

If your video card support it, you can generate a custom resolution of 400x240px on your hdmi/dvi/dp output connected directly to the LED transmission box, this way, only the video player will resize once the video, keeping the sharpness at its maximum.
