Samsung 40" LED 1920 x 1080 5000:1 VGA DVI-D DSP HDMI 8MS 3-Years Warranty TAA DM40D

These displays are apparently part of Samsung's "professional" series line. That's why I selected them, for the 24 hour per day operation in our small school. However, you have to BUY EXPENSIVE SOFTWARE to make them work. You have to buy a license for their MagicInfo SERVER and their MagicInfo authoring software as well. The TVs might be nice, but you get nothing at all to talk to them unless you buy some additional software. Unless your idea of content is JPEGs on a thumb drive, these TVs are big bricks--unless you bust out the credit card. The displays might be lovely but the total package is two stars because of the hidden costs.EDIT 9/14/2015. We have contacted Samsung REPEATEDLY to try and purchase a license to MagicInfo Server and they REFUSE to call us back. The tech support line will get you to a person, but they can't help you and transfer you to sales, where you leave a message and never hear anything. Our trial key is running out and no one at Samsung will help. Be VERY careful purchasing this product, because controlling it will be a big problem. Once again, the panels are GREAT, Samsung tech support is fine, but Samsung SALES is worse than terrible. Baffling!

Arrived on time and works flawlessly.
