Overscan Using HDMI but not VGA
Need help here. Have looked high and low for a fix or a tool to fix overscaning. I know its a Nvidia driver problem because when i uninstall the Nvidia driver the system reboots and uses the generic windows Vista driver and my overscan issue is gone. When i install any Nvidia driver the overscan kicks back in. Can someone please show me a fix for this. This only happens to HDMI not VGA. When connect via VGA the resolution is perfect.

Right now there really isn't any official fix. I have the exact same problem as you.

Seems like i have fixed it.
All i did was delete my Viewsonic Monitor and drivers from device manager and add a monitor call Generic PnP monitor. Now overscan is gone. I did notice if i press the input button on the Monitor to HDMI it overscans again but when i hit the button to activate HDMI it again it fixes the overscan issue. Weird.

When your monitor detects an HDMI audio infoframe, it forces overscan. Your graphics card is sending audio over HDMI and therefore your Viewsonic monitor is detecting it as an HDTV and forcing overscan. When you change the monitor to Generic PnP, it is disabling HD modes and therefore the Viewsonic monitor is not detecting the monitor as an HD CE device and therefore behaves as a PC monitor. We will have an EDID blacklist incorporated in our next driver to detect monitors such as this one that force overscan when it detects HDMI audio.

Thanks for the reply.
The audio detection infoframe makes sense now that you have described the issue.
How will i know which driver has been release for this fix? and when would that be roughly?
By the way my Monitor is the Viewsonic 2835wm so i hope you add this to the EDID blacklist with overscan issues

I'm also wondering if my TV, Insignia, will also be on that blacklist.

Can you get the EDID of your Insignia HDTV using this utility and copy the text into this thread and I will send it off to our driver team:

A check-box or slider in NVCPL would be a very useful feature as an override for EDID.

Please add this EDID to the blacklist:

[url="http://www.postnewspapers.com.au/~craig/edid-hdmi.bin"]http://www.postnewspapers.com.au/~craig/edid-hdmi.bin[/url]

It's for a Kogan KGN1080P32VAA, and it looks like some drooling moron thought it'd be a good idea to force overscan whenever a HDMI audio signal was detected.

It'd be really helpful to have control over HDMI audio in the Linux driver so problems like this could be isolated. Think: "Option DisableHDMIAudio True". Right now, I'm only guessing based on the test results reported here [url="http://forums.nvidia.com/index.php?showtopic=183214"]http://forums.nvidia.com/index.php?showtopic=183214[/url] ; if there's something else the video card might be negotiating with the TV as well as HDMI audio that could be the culprit, then perhaps that should be examined before blacklisting the device.

Is there going to be any way to make HDMI audio work with blacklisted devices?
