So Windows 7 has been around a little while now... has anyone figured out how to prevent it from changing resolution when I turn off the monitor?

Win 8 solved it so there must be some clever chap that wrote a freeze resolution code. No? I'd just love to turn on the screen and have all my windows in the same size as I'd left them.
 
Oh is that right!

I haven't used the DVI port for my previous monitor nor the current setup, so yes I'm using the displayport and have done so for several years now.

Hmmm the plot thickens.
 
The windows do indeed remain the correct size when I connect to the DVI port.

However, my issue has always been the lack of audio over the DVI port (I know it carries audio but I can't ever figure out how to enable it) so that's why I end up using a displayport to HDMI adapter.

While connected to the DVI port, the NVidia control panel tab 'set up digital audio' option shows 'no audio capable display available'. Which is strange since the HDCP status shows "your graphics card and display are HDCP capable".

Plus, if I'm able to get audio from the displayport then I should be able to get audio via DVI too.

I own both of these DVI to HDMI adapters and neither provide audio, I'd assume the former would provide full data transmission but the later came with the card.

this also happens with a few of our HP Desktops at work. It doesnt seem to monitor specific but is definately linked to displayport.

being a business we dont need the sound so on these desktops went back to DVI
 
It's working now!

I have three DVI ports on my GTX 590 so I shutdown the PC, switched the adapter (the gold adapter pictured above) to another DVI port, turned on the TV and then powered up the PC to hear the lovely startup chime.

All working. Thanks for all the help chaps!!! :D

Nope no audio there:D
 
So then why am I now successfully receiving audio using a DVI (from the graphics card) to HDMI adapter?

Also, my old Samsung monitor used a basic DVI cable and went from DVI on the graphics card to a DVI port on the monitor... and still provided sound.
 
one of the main reasons DVI-I/D was superceeded so soon by both DP and HDMI was its inability to carry audio. im sorry but DVI as a standard cannot do audio.

some gfx cards do a fudge for DVI to HDMI but DVi to DVI is a no no
 
My old AMD APU HTPC system would do this, it would drop to 800x600 if the HDMI link was terminated (ie the TV was turned off). Doesn't happen with my Intel HTPC.

Yeah AMD cards force audio out somewhere on the DVI connection and then the DVI>HDMI dongle strips it out to a proper audio over HDMI link.

Edit: I'm surprised that the Samsung monitor handled sound over DVI, you sure you didn't have a separate audio lead?
