Let me start with explaining my setup with my monitors. I have a 42 inch TV that I use as my primary driver monitor. I then have 2 24 inch monitors on either side of my TV that are in portrait mode. Here is a picture for those who want a visual.

I have a fourth monitor (because that's always been the end goal) that I want to place above the TV and angle down. The TV does have a VESA mount on the back. I was really hoping to do a VESA to VESA arm that would easily allow be to adjust angle as well ad not make me have to clamp another arm to my desk.

I believe that what I am looking for doesn't exist outright. I am very good with my hands, so yes, I could build one from scratch. I do not want to go that route because I just have the time in my life right now. If anyone has any ideas or knows about what I am looking for, that would be fantastic.

TL;DR: I am looking for either a VESA to VESA monitor arm or a different solution that doesn't require another clamp.
