Hello fine gentlemen and ladies of reddit, I need some help with the following problem:
For my local sportsclub I set up a pc with a hdmi-over-utp device to some bigAss" tv. This worked great, but after a few days the device just stopped working (turns out after a reboot). I bought a new hdmi-over-utp device from another creator (they are actually quite expensive), but this didn't fix my problem. I still could not boot the machine and have hdmi-over-utp working.
After a while I found out that the hdmi-over-utp only worked when I first booted the pc with a direct hdmi device. Of course, this is of no use to me. I am not sure if it's a basic problem of hdmi-over-utp, or that it's just a stupid error in my version.
So now, I can boot it up bringing my own tv to the building, booting it with a hdmi direct cable, then after it booted, switch the hdmi cable into the hdmi-over-utp box.
So this is a temp fix for now, but i do have a problem, since I don't live near the place, and sooner or later some bloke will reboot my machine. 

I hope to keep the hdmi, since it's such a bigAss" tv, but the machine is already rebooted 3 times, and I really just want it to work. I am even willing on downgrading to a vga-over-utp (I was initially trying to get this thread going on about my best options for that).

(btw: I have tried all settings in windows which i could find, and i can't seem to get it to work in current setup. I think the hdmi-over-utp box doesn't send out the initial tv-hdmi signals, so the pc can't understand what kind of screen is connected. I noticed that once I used my own tv to boot it, the bigAss" tv resolution settings on windows was limited to my own tv's resolutions)
