External monitors connection stability

[dee99]

One of the more frequently asked questions is how to recover when windows loses connection to an external monitor / projector. This can be caused by a loose cable or and intermittent wireless network connection. At this point windows loses all connection and memory of the display. In order to get the display back windows has to negotiate with the display and create a new connection before allowing the display to be created internally in windows which can take quite a few seconds.

One method that can help is to use an EDID device between the PC and the monitor, this device is normally a small inline HDMI, DVI or VGA device that acts to windows as a display device and passes the video signal through to the monitor. Their original purpose is to correct display Id message corruption but they are a monitor emulator which enables them to give windows a stable monitor connection even if the actual monitor is turned off or disconnected.

Here is a link to some information about EDID devices.

We have tested SCS with a LINDY 32115 HDMI 2.0 EDID Emulator from https://lindy.co.uk
To windows it behaves like a monitor with a wide range of resolution settings and is capable of cloning the video resolution passing through it.
This model also supports 4K @60Hz monitors.

This method will not work for inbuilt wireless video connections, due the fragility of a wireless connection particularly in a show environment. We would recommend that you use wired interfaces wherever possible. One method of extending your HDMI is to use a CAT5 / 6 / 7 converter box to send the signal down standard Cat 5 /6 /7 cable and a receiver box at the far end to convert back to HDMI.
