At DMC we pride ourselves on being tech-savvy and using appropriate technology to solve common problems. So as we moved to our new office space this month, we didn't want to be constrained by the wires that link to our new conference room projectors and wall mounted displays.
The solution we have implemented is the InFocus LiteShow III. We have three of these on our office network. The LiteShow III is a small box with a wired and wireless network connections, and a VGA video output. We have hooked up a LiteShow III to each of our conference room displays.
Now, anyone on our network can project their laptop's screen onto any display without connecting a monitor cable. We use the displays' HDMI input to connect with dedicated conference room PCs.
Using an external device for projector sharing has several advantages:
- Allowing us to use less expensive projectors and wall mounted displays that don't have proprietary digital interfaces.
- Unifying connectivity to all displays, regardless of brand or function. (Projects are the same as flat-panels)
- Freeing us from passing video cables
The LiteShow III is the best solution that we've found, but it does have some drawbacks that we hope to see InFocus address in software upgrades or future products:
- The native resolution of the LiteShow is 1280X800, which doesn't optimize our full 1080p displays. We would like a 1080p version.
- The LiteShow software always asks you when you connect to switch to 1024X768 resolution. We wish it wouldn't ask.
- We have found that 1440X900 is the best computer resolution to use with a LiteShow. It sets the LiteShow in the right aspect ratio with the minimum interpolation.
The LiteShow III can operate through wired networking, or using its wireless interface as a client or an access point. We have found it best to connect the LiteShow to a wired infrastructure network, and use wireless other access points to connect to the network. Unintuitively, before disabling the wireless network, it is important to set the SSID to the room name because that is what will be used to select which LiteShow on the network to connect to.
We have found that it important to configure a static IP address for the LiteShow. While it has a DHCP client, it only seems to look for an address at startup. After we had an extended power outage, when the liteshows booted before the DHCP server, they took a default address and never connected to DHCP.
