Routing the HDMI stream through the receiver caused problems

[nir211]

Hi,

configuration: data source is a graphics card (in my PC) with two ports: DVI that is connected to a monitor and HDMI that used to be connected directly to a TV (Audio was outputted separately to receiver), but now is connected to the receiver, with another HDMI cable connecting the receiver to the TV. So basically the connection b/w the PC and the TV is via the receiver and HDMI, and to the monitor directly via DVI.
All works well, except that when I close my TV it shuts down signal the to the monitor as well. This did not happen when the TV was connected directly to the PC (via HDMI), only when I connect them through the receiver (hence this is a receiver question).
How do I change that?

Configuration:
LG W2043T monitor,
LG LD460 TV,
Yamaha RX-v467 receiver,
ATI Radeon HD 4300/4500 series graphics card.

Thanks!!

** Please note that the pc desktop is extended to the TV.

However, it was also like that when the PC was directly connected to the TV, and then turning off the TV did not kill the signal to the monitor.

Everything is operating as it should, according to the current rules.

HDMI is a two way communication, DVI is not.

So when the TV is shut down, it tells your receiver not to output a signal.

The monitor being DVI can not tell the system is still on.

There is no solution to your problem except to make all screens HDMI, or leave the TV on.

You can try disabling control for HDMI on both your TV and receiver. Most have that setting although it may be labeled differently from brand to brand. There may also be a setting on the graphics card to disable HDMI control.

You can't do that now. Defeating DRM of HDMI is illegal.

As usual, DRM only hurts the paying customers and the hackers still win

He's referring to CEC, wouldn't help in this situation but has nothing to do with DRM.

You could try messing with power settings on your computer to disable monitor power savings?

Yes, I would turn off HDMI CEC in the A/V receiver which I'm sure is a buried option under some other name, but will likely be in there.

It is also incorrect to say DVI is not a two-way communications stream as even old-school VGA has EDID information and communication which is how your old analog PCs picked the right resolutions for monitors. DVI is fully capable of HDCP handshakes along with EDID...

Perhaps making your monitors emulate each other and set the PC monitor as the primary monitor?

Could work, but hard to say. I think the HDMI control (CEC) is the first thing I would try to disable in the settings for the A/V receiver. Also, in the PC if there is some option there to adjust/disable it.

Thanks guys for your answers.
Sorry for being out of touch, I had a lot on my plate lately.
I'll give it a go and see what happens.
So far, I've found out that this occurs when I set the receiver to "direct", which is a mode in which the receiver has minimal interference with the stream.
However, when it's on a different mode, the resolution of the TV is reset every time the computer is restarted, and set to a low 480p resolution. I change it, and this holds up every time up to the next restart of the PC.
