Got a tech question. I recently connected my Palit 4870 to my Onkyo TX-SR605 through the DVI->HDMI adapter and have my receiver outputting to my monitor. However when I set the PC to the proper resolution of 1680x1050 somewhere along the line the image is slightly stretched out and blurred. The monitor works perfect with other devices so it's either the GPU or the receiver, probably the Onkyo. Has anyone else run into this and figured out a way to solve this so that the video is not altered in anyway when it passes through the receiver?
The problem is that you are feeding a 1050P signal through a 1080P reciever. It wants an input image of 1920x1080, but is getting 1680x1050 instead. Your best option (other than bypassing the reciever) is to set the resolution to 1920x1080 or 1280x720. This will either waist part of the screen with black bars, or it will skew the image slightly (stretched about 11% taller than normal). If this does not work for you, then your only option is to bypass the reciever, as it is not designed for your application.
As i've fooled around with it more I have come to the same conclusion which I find ridiculous that the machine can't simply have video passthrough. What I ended up doing was running DVI->HDMI to the receiver for audio, and DVI->DVI to the monitor to have the video go straight to the monitor on the 2nd DVI port. Another annoying thing I have noticed is that when my BenQ monitor has an HDMI input that is off it will continue to display a solid blue screen instead of powering down like it does on the DVI port so it's better I go this route anyways. It still forces me to have to get up and change the inputs on both my monitor and my receiver when I want to use my PS3 but at least it works.
There are boxes designed for exactly this purpose...they are often called "KVM" boxes, or "DVI(or hdmi) Switch" or "DVI(or hdmi) Matrix" Most have remote controls, and they will let you do a true pass-through switch without messing with your image.
Aye. Getting a workaround isn't a problem. Only getting a simplified equipment setup to work as it should is the problem. It would be ideal if my HT receiver handled all the audio and video but it looks like i'm stuck doing a lot of fiddling to switch back and forth. I do find it quite odd that a monitor would not shut itself off after losing a signal from the HDMI, but would if you use the DVI port instead. Oh well
It is unusual...it would defeat the method I use to switch inputs (turning off the video output to one of the inputs on one of my screens makes it automaticaly go to the other input...this can be done easily without getting up).
