Using a 1024X768 res with new Windows 10 computers & new widescreen monitors

fairtech used Ask the Experts™
I have a legacy application that doesn't optimize for a resolution above 1024X768. As most of you know these days new computers and monitors want much higher resolutions. Does anyone know how to make a new computer and widescreen monitor work \ scale to full screen with a 1024X768 resolution?

1024x768 will not look good on a modern 16x9 monitor if stretched to the edges, and it will letterbox if not stretched.  And in any case 1024x768 is not something to be running on a modern system when the display is capable of much better resolution.

If the computer in question is capable of handling more than one monitor, consider buying an older 4x3 aspect ratio LCD monitor, then attach it to the system as the second monitor.  Then run the application on the second monitor.  Any local electronics recycler should have a boatload of 4x3 LCDs.

You still should be able to set that resolution, but what exactly do yo mean with "doesn't optimize"?.
Do you need to run that resolution only when using the application? Or is it the main application. so you need to have that resolution permanently?

Install the application in a VM with that screen resolution then use VMware player.

I have found a solution. Can’t believe I missed this !!!! I have been just defaulting to use the display settings built into windows. There is actually the Intel HD Graphics Control Panel on the PC’s I have and it has the option to “Scale Full Screen”.

a) We said you can use the resolution
b) that will look awfully distorted, as has been said too.
Qlemo I knew that I could use 1024X768. My question was does anyone know how to use 1024X768 and scale to the full screen.
Also in my situation the screen doesn't look distorted at all.

Thank you for you help

In case someone here knows: there is a compatibility setting for applications that will set the VGA mode (640x480 pixels). I haven't investigated, but it could be that we may force other modes using shims (shim files can be created by ACT5 or higher: - download no longer available, though). That would mean, we could keep the native resolution.
