5D Mk III random hdmi frozen frame

Issue #1764 new
Former user created an issue

Sometimes, when using an HDMI monitor, I have stumbled upon a frozen image. The User Interface continues to update, but the image coming from the sensor appears frozen. If I disconnect the hdmi cable, the image becomes unfrozen again on the onboard display, but will sometimes again stay frozen upon reconnection of the hdmi source. The only 100% way to make it go away is to turn the camera off and on again. The problem appears to be sporadic. Sometimes it happens many times in a row, sometimes it can go on for a long time without happening. When this happens my UI is set to display a raw RGB histogram and a spot meter. I have seen it on two nightlies incluiding today's.
