[Elecraft] External Display Freezes after Delay

[brenntl]

I have a nuisance issue with the P3 and an external display. When I apply
13.8VDC to the K3 and P3 simultaneously (P3 POWER button must be pushed to
turn on the P3), the external display displays the image first followed by
the image on the P3. This all appears to be normal operation.
Thirty seconds after the image appears on the external display, the display
image freezes and remains frozen and the image on the P3 remains normal. If
I then turn the P3 POWER BUTTON off for a few seconds and then turn it back
on, the image reappears and remains working on the P3 and the external
monitor until I power the whole system down. This sequence of events is very
repeatable, including the time it takes the external display to freeze, and
has done this since I first built the P3.
I have had the same result with 2 different displays. Reloading and
installing the latest P3 and SVGA firmware has no effect and nothing changes
from that described above. It does not make any difference whether I have
the display power on before turning on the P3 or after. I have searched
posts and found nothing on this specific problem.

CONDITIONS:
K3 FW: MCU Ver 5.64
P3 FW: MCU Ver 1.60
P3 Options: SVGA installed running Ver 1.34
P3 Ext. display resolution: 1280 X 1024
