So OK, here is what I have found....
I have an original old 25" Wells monitor with the curved tube that is no longer available... the tube is 22 &5/8" wide and the brackets are 23" wide.
I also have a set of the brackets Makvision Used on their 25" using the same tube, they are 22.5" wide.
I measured our brackets to be 21 & 3/8" if the tube is mounted offset left or right of the brackets the total dimension could be as much as 21.5".
My guess is that bothe Wells and Happ/makvision have not updated their sites.... I guess similar to their support out of date??
By the way if anyone finds any error on our site please... please let me know, we will correct it. email me Rick@niemandisplays.com
thanks again and good luck
