So, I just bought and installed a Yamaha A710 to replace my Samsung HTIB I've been using for years. I was super excited to get it going after plugging everything in, but when I saw the picture it produced, I was very upset.
Let's start with what I had before installing the new AV receiver:
Toshiba 37AV502R 720p TV w/ 1366x768 panel
Windows 7x64 PC w/ 5750 GPU direct to TV.
The Samsung had no HDMI inputs, so I sent video direct to the TV and had 5.1 audio via optical out from the motherboard.
For whatever reason, hooking a PC up to the Toshiba causes the default resolution go to 1080p, which looks terrible. I'm not sure why the resolution is even a choice. All I would have to do is change the resolution using Windows's built in settings to change the res to 1366x768 and everything was fantastic.
So after I installed the A710 and turned on the TV, the resolution defaulted to 1080p, and I immediately changed it back to the TV's native resolution. But everything still looks awful. Text is less than sharp, colors are saturated, faces are blotchy and there is aliasing everywhere. The Yamaha itself is still up-scaling to 1080p. Even when I change the resolution to 1280@720, the Yamaha will not scale that, but the image looks terrible because that isn't the TV panel's native resolution.
I need some help understanding how to fix this. There is an advanced option for the Yamaha called Monitor Check, which I have turned off. No dice. I need the Yamaha to do no scaling at all, and I think that's what will fix my issue.
