Question

Shaky Hands HDMI?

Jan 16, 2015 7:39AM PST

Evening,
I have a problem that has been plaguing me for a week now. I have just built a mini itx pc (for HTPC/gaming use) that sits under my TV. It is connected to my TV via HDMI.

I cannot for the life of me get the PC to display an image on the TV. I have checked the refresh rate, the primary monitor settings, the resolution, changing the cable, updating the drivers and nothing works. There is one caveat here though, it does work when I have a standard computer monitor plugged in. If boot the machine up it initially displays fine on the monitor, then when i unplug the DVI connection it defaults to the TV. As I'm sure you can imagine it's not ideal having an additional monitor just chilling next to my TV, kinda defeats the object.

The only thing I can guess it might be is something to do with a "handshaking" routine that I've read a bit about but do not fully understand. SO... if anyone is able to shed any light on what i can do to fix this that'd be great. I currently have a £500 doorstop!

P.s. I can confirm that a picture does appear exclusively via hdmi when connecting to a different tv.

Thanks in advance,
Tim

It is a Toshiba40bv700b. I haven't been able to locate any settings that would affect hdmi input.

I think you may be onto something there but I've looked through the menus thoroughly and this option doesn't show anywhere sadly.

are you have the proper hdmi source selected for the tv. If that does not work, then I am at a lost too.

It is currently working thru the tv, but I've had to boot up with the monitor connected then unplug the monitor. So it's on the right hdmi channel. Thanks tho mate.

I really think this is an edid issue. Anyone else have an idea?
