My brother-in-law was having a similar problem with his computer connected to a 1080p 50" LCD panel. Every resolution would show up perfectly fine but 1920x1080 would get overscanned. After a lot of searching around the problem was, believe it or not, the panel's aspect ratio setting, even though it was set to 16:9 mode. If your panel has such a setting, try adjusting it. If not, you could try manually setting which display timing method to use in your graphics driver options.

Most TVs know that through VGA the signal is from a computer. From HDMI this isn't so obvious...

The TV should have a setting basically telling it that the HDMI signal is from a PC and to use 1:1 pixel mapping. Sometimes it is a certain HDMI port as well.

To combat this video drivers allow underscanning to counter the overscan the TV applies. But this is basically scaling twice and should be avoided.

So the scaling should be set to 0 in your driver and then check out all the options in the TV. Most half decent TVs have a 1:1 pixel mapping option although it can hide under other names.

Mine calls it graphic mode...

I've been using my new ASUS HDMI display with the VGA input for awhile due to not having a USB keyboard.

What display has to do with keyboard?

This is basically what I did in the AMD Vision Control Panel, the settings were not at ZERO but under-scanned.

I also found the overscan setting on the ASUS monitor too and tried it but it really was really needed, tried it to see but was no different then using the options under the GPU settings.

@Robertmo, initially I was using a PS2 type KVM with this monitor as it also has a single VGA input as well. My old KB was a PS2 type and I didn't want to updgrade the KVM switchbox until I get both a new USB keyboard an HDMI switchbox at the same time 😉

Also, I have only ever seen a USB 2 PS2 adapter for keyboards nor the other way around, PS2 2 USB, I'm sure they are out there but I really needed a new KB as the older one was starting to get carple key syndrome :p
