I’ve got an old tablet PC I’m using and I installed a program called yawcam on it. I set the tablet to turn off the display after 5 mins and set up yawcam’s motion detect feature to send an F5 if there is movement in front of it (if it hasn’t detected movement in 5 mins) . This has the effect of turning the display on and refreshing the panel. It also keeps my mjpg ipcam stream active.
