While searching for an alternative, I came across digital signage. Why they call it that instead of "really big touch screen monitor" is baffling. They would sell 1000 times more if they marketed the product correctly. So, HP has a line of digital signs. Most are not touch screens. However, there it was. For under $2,000. The HP LD4200tm. I called and asked if it would work as an extended screen monitor. They had no idea what I was talking about. On a good feeling, I purchased the product. It was all that I wanted and more.
It was a light-weight portable touch monitor that could function as an extended screen. Better still, there were VGA, HDMI, component (2), composite (1), and S-video inputs (1), and a VGA out for Tiling. You could then have a separate monitor that mimics the touchscreen for the Judge. Or, you could have it set to record the presentation. This provides an infinite amount of possibilities in courtroom setup.
So, at 42" it is not overpowering. There is no shadowing caused by projectors. It requires only a USB cord, a VGA cord, and a power outlet. This minimizes the amount of wires that are strung about the courtroom.
You can buy the digital signage speakers which will attach to the LD4200tm. However, I utilize stand alone speakers attached to the laptop instead. No need for more wires to be run anywhere.
Figured I'd share my experience with the touchscreen. Also, the previous post is about how to make the touchscreen work in extended mode. I called customer service at HP about 10 times and none of them though that it was possible. Then the solution came out. The new old-fashioned way. I looked on the internet. And there it was.
