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.

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

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.
 
Now I can see the confusion! Learned something new today :D

The first approach to figure out if audio is possible is to look at the standard and the pin layout. Since the DVI standard doesn't support it, that explains why you find so many adamant posts that DVI does not support audio.

There must be some form of standard in place for monitors to understand how to access the DVI audio content, I literally had a DVI to DVI connection with my old samsung monitor using an ATI 4870 and an NVidia 470 with zero issue sending audio. I definitely didn't need a separate audio lead and I didn't use a DVI cable supplied with the card.

EDIT: Actually the ATI 4870 did send DVI to DVI audio but, now that I remember, the NVidia 470 would not send audio over the same cable so I had to connect to the micro HDMI port on the card and use a microHDMI to DVI cable.

I'll check, because it's quite an interesting discussion and I'd really like to know if it truly was DVI to DVI.

I think that Samsung monitor had a plethora of connection options in the back (component, composite, VGA, S-Video, coax, HDMI, etc) so may have been more of a TV than a monitor.. I've either got the model number some where or the monitor itself so I'll find out.

My apologies, it certainly was DVI to HDMI. That older display set didn't have a DVI port (had about every other connection option) so there's no way it could have been DVI to DVI.

That's really interesting; so DVI does carry audio but the audio data is only accessible when converted to HDMI.
 
Sorry, but did you read James' post directly above yours... ?

It's incredibly misleading to state "DVI doesn't carry audio" with respect to a PC application. How do you explain that audio is received by connecting to the source via DVI port but still maintain that DVI does not carry audio?
