HDMI output on Gigabyte Brix Pro, working on some displays, not others

My office has a Gigabyte Brix Pro that my boss wants to be able to take with him occasionally to work from home on it. The problem is that it has issues (or a monitor with it) with the HDMI output to the display (it only has HDMI output and miniDisplayPort).
Here's what has happened so far:
Take boss's HP Pavilion 27-inch LED monitor and hook it up with his HDMI cable. Works fine.
Boss brings in a (can't remember...acer or samsung) monitor from home that has HDMI input, same cable. Monitor does not display, neither of us can figure out why. He uses the monitor with his laptop so he knows it works.
We purchase a JVC 39" 1080p LED HDTV with HDMI inputs and a new cable. Works fine.
Boss takes Brix home and tries to use it with a new monitor he just purchased and the same cable we had used for the first two monitors, does not display.
I'm at a loss, I do not know why some displays will work and others will not. I don't think it is the cable, since it worked with one display and not with another. The Brix works fine, I did not detect any hardware issues though I may take a shot at reinstalling display drivers (?)
Edit: I'll add that Windows would not load until I switched from EFI to Legacy boot mode in the BIOS. That's the only modification I had to make when I set the system up. Also both monitors that have not worked properly may have been Samsung...but that still doesn't make sense to me if true.

I have an ATI Radeon HD 5700 graphics adapter which I am trying to connect to a TV and a monitor.
With only the monitor connected everything works fine, however as soon as I plug in the HDMI cable going to the TV the screen begin to flicker.
I have updated the system bios and the graphics driver and the problem remain.
The screen flickers during POST and in boot up menus when the cable is connected so the issue doesn't seem related to the os (win xp) or my drivers.
The flicker may remain even after detaching the hdmi cable and require me to disconnect the computer from the mains to get it working normally again.
When connecting my laptop using the same cable to the tv in question, the laptops display does not flicker. So the tv and the cable should also be ok.
Can anyone shed some light on this issue, is it a broken gfx adapter or can it be something else?

I would have to guess that it is a hardware problem or technical software setting? Do you have a VGA cable because you could try that and see if that works? It will give you slightly less quality if you are trying to play blurays or something however. You should also try checking the refresh rates. If it is too high or low it may be causing the flickering. You should be able to experiment with this by right clicking the desktop and going to 'graphic properties'. There are also a lot of other settings in this panel that you can try playing around with. Check the specs of the TV to make sure you our outputting the correct refresh rate. If you make any headway, then post here again and I will see if that helps me any in diagnosing your problem. Best of luck!

The issue here is most likely that the basic speed on core and memory (157/300) does not provide enough power for the hdmi output.
Dirty FIX: put something else playing on desktop meanwhile, so the gpu automatically up's the core and memory speeds higher.
If you find better solution - please, let me know.
PS. Ofcourse you can always reprogram the GPU Bios, but that seems a bit harsh move for dealing with an issue such as this.
It's the infamous "desktop clock speed" problem all over again.
