I have an older Viewsonic VS12264 LCD monitor. It's been a great little unit, which I used to connect to via DVI.

 

However I have needed to change to HDMI. I now have a few different PC's in my office which I share with the same screen, keyboard and mouse, so I'm using a HDMI/USB KVM device.

 

The VGA Card in my main PC has both a DVI and HDMI port. However I can't plug the HDMI cable direct into the HDMI port - I think the PC case actually prevents the cable from seating 100%. So I purchased an adapter (something like this:  https://www.jaycar.co.nz/hdmi-socket-to-dvi-d-plug-adaptor/p/PA3644) and my HDMI cable plugs fully/properly into that. 

 

However, for the life of me, I can get my Windows desktop to "sit properly" in the monitor window. There is a small portion of the Desktop, which sits outside the physical window of the monitor.  The monitor settings are useless and don't offer much value (as far as I can tell) and I can't seem to find a way to adjust the desktop, either through Windows Settings or the VGA software.

 

Any ideas?

It's almost as if there is some sort of Overscan happening there.

 

You've tried the monitor's 'Auto' setting (on most monitors, you press it, and it shifts things around until they are centred).
Is there an Overscan setting in your graphics driver properties anywhere?

That's exactly it.

 

A lot of (older, especially) monitors have HDMI inputs which the monitor can drive in two ways - one with overscan enabled and one without.

 

Look for settings in the Monitor's menus with names like "VGA" or "computer" vs "VCR" or "TV".

 

There is almost certainly a value to toggle there somewhere.

I have seen these issues when using a KVM, try going direct and seeing if the issue resolves itself.

I've found this to be a problem on most TV sets I've used HDMI input on. However it almost always seem to work flawlessly on most non-TV sets (e.g. monitors designed for computer usage). Interestingly I've observed that VGA output sometimes work flawlessly on the same sets that HDMI has overscan issues. Wonder if the TV sets assume VGA input is from computers and adjust accordingly?

 

Anyway just wanted to add that macOS has an overscan option in monitor preferences and I'm pretty sure I recall Intel/Nvidia/ATI providing this option deep inside their advanced settings. This can fix things from the computer side.

 

But good to know there is some setting on the TV set itself. Will have a closer look next time.

Hi All,

 

Just thought I would provide an update:

 

1) Found settings on my VGA Driver Software, which allowed me to "underscan" so that the desktop would properly fit in my screen. However the quality of the picture dropped expoentially.
2) After some fortuitous Googling, I managed to find an article on Overscan which related to slightly older monitors like mine - make sure they are set to 'PC Mode' and not 'HD/Movie Mode'.  Sure enough, my monitor was set to 'HD Mode' and changing it to 'PC Mode' did the trick - it turned off the Overscan feature.

 

Cheers,
