I am using two HP 24f monitors side by side. I bought them three years ago at Costco.
Here is the setup look.
HP 24f monitor doesn’t have standard VESA mounting screw holes. There is an insert tab on the back of the monitor.
I found it on a website, but I can not find it now. I forgot the original link. If you know it, or you are the original designer, please let me know. I will add the credit.
Here are four pictures I forgot to upload here.
It is a great fit on the back.
Mount them with the screw.
This is the final look. It is clean and clear. Because I use one screw to mount the 2X4 on the desk. So I can turn it.
The key point of drilling the holes in the desk is the distance between the two monitors.
