Thank you for joining the Intel communities.
We have seen customers who want to implement this EDID, in this case you may want o check this information at the following thread:
I do signage too. We have far too many Gefen EDID emulators deployed and I don't like them at all, they die mysteriously.
EDID issues with the HD 4600 just bit me in an interesting way too. (At least it is not the disaster that DP brings on.)
Monitor in standby mode does NOT return an EDID (think AQUOS, low power standby)
STB powers up, gets no EDID, assumes 1024*768, starts playing just fine.
STB turns monitor on, gets 3840*2160, but player software ignores this. Some hours later, content starts, WMV's (just full HD but still.)
Memory leaks from the driver caused by the player software, 8 GB disappears in about 15 minutes, player crashes but system does not recover.
Trivially reproducible with our software -.- Just ignore WM_DISPLAYCHANGE
The reverse does not happen though, once the graphics driver has an EDID, it will hold onto it when the monitor is turned off and disappears. Our player does not care.
This also does not happen if the monitor is on when the STB boots. It really appears that WM_DISPLAYCHANGE is the instigator.
I would like some sort of "keep this EDID" (export/import) ommand I can send remotely so we can completely ignore what the monirot does and not have the player fall over.
I would probably consider homicide for a version that did this for DP, hot-plug there causes more problems than it solves.
Of course, I would be happy to have this massive memory leak fixed, but first I need to know how to prove it is the graphics driver leaking.
Oh, Windows Embedded Standard 8.1 Industry Pro using i7-4700EQ's. Quite a few of these now. 188.8.131.5232
Were cancelling our latest HP Order if the HP-MP9-G2 players because of this issue and the total procrastination of Intel giving us a fix. Were swapping to an iBase unit with AMD drivers. This has total EDID control via the graphics drive software. The demo unit works like a hot damn….
All in all we get way more hiccups with Intel Display graphics signage players than other. The total package is lovely mind you but the support time for intel compared to AMD is what we see the major time saving in.

I’m sorry for any inconvenience with this, at this point I suggest posting your concern at the following link since this was already escalated through that thread:
