I am designing a conference room that will have two Sharp 65" LCD panels in it. We are doing the LCD panels instead of the traditional projectors.

The conference table will have three spots to connect laptops and we also may have an input into the system for a Blu-ray player.

The LCDs will be up to 60 feet from the laptops on the table (due to cabling going under the table, up a wall, and over.

I've looked at the twisted pair options to do this (including the switching). I'm trying to learn more about the best way to do this (manufacturer and models). Extron is one of the companies that sell this type of gear.

Our main concern is switch laptops with different resolutions to the LCD panels. Should be let the LCDs handle and scale the input or should we put a switch in between that can do the scaling to the resolution of the LCD (1920 x 1080)?

An example transmitter receiver from Extron is at http://www.extron.com/product/produc...01&subtype=215

Thanks in advance for your ideas

First off, which type of output are you planning for the laptops? That will make a difference. Generally a switch is the simplest thing. But, you will likely use HDMI for the Bluray, and though the newest laptops have HDMI out, it is not the majority of them. VGA switches would work fine for the laptops, but not the BluRay. The other tricky part is that VP's don't usually have 3 VGA inputs, so that might not work either.

Surely anyone whose laptop doesn't support some kind of digital video output wouldn't be bringing it to such a fancy conference room. Let VGA die.

The Lumagen RadianceXE and HDQ video processors have plenty of connectivity for your conference room system. These units are installed in many classrooms and conference rooms. Rack mount ears are available for both units.

The Radiance has two HDMI outputs to drive the two monitors. It has six HDMI inputs. There are four component inputs. The input type for component input 10 can be set to RGBHV (VGA) to connect a laptop.
