Hi,
Another option could be a VGA to USB capture.

You capture the video on another PC that has proper HDMI output.
I don't know if the above works with Linux or not, as I have not tried it.
Another option, is to find an old graphics card that does DVI, and install
it in the old PCs.
Another option, is to buy a better display, that supports VGA and HDMI
inputs.
Another option, is to stop using the old PCs entirely, and get newer ones.
You don't explain why you need the old PCs.
