I've got an Acer iDea 500 connected to a Toshiba 32WLT66 via HDMI. The acer is running W7, but is otherwise as we bought it (though the power light is always blue now, not that this is the issue. It's running at 1280x768 - the Toshiba is 1366x768, but as far as I can tell, this is not an achievable resolution.
The problem I'm having is that a lot of the time I am having to unplug and plug the HDMI connection from the PC in order to get the display to come on. This is because when the TV is off (or on standby), the PC thinks it has been disconnected (get the device disconnect sound). It doesn't think it's been reconnected once you turn it back on, however, until you unplug and plug it back in.
If the Acer is always put into Away Mode (all output goes off, though it's still running and recording stuff) before the TV is turned off, and the reverse when turning it back on, then the display it alright. If, however, the Acer is woken up, either by us or by the system, before the TV is turned back on, then it thinks the TV is gone, and we have to give it a reach around to get it to come back on.
We used to be able to use a hotkey, set within the Intel Graphics Properties interface, to "Enable Digital Display", which would bring it back on, though this stopped working some time ago, despite the rest of the hotkeys (rotate, open properties window) still functioning as per usual.
Anyone got any ideas? Anyone know if you can force the card to output to that device even if it thinks it's gone? Any and all help would be appreciated.
Cheers,
Joe
