Adjustable VESA Monitor/VDU Mount

This note describes a simple solution for a precision height adjustment method for a computer screen. The necessity arose from my need to align the centre line of three screens as I use a MATROX Triplehead to Go to create a wide screen of 40" from three monitors.

I use a visual trick by using a central 19" screen flanked by 17" screens to reduce the width of the observed border; I discovered that by setting the larger screen only 10cm rearwards that, from the seating position, it appeared the same size as the smaller screens.

It is easy to place the screens horizontally but the vertical alignment of the centre line has to be exact so I have designed a simple adjustable mounting using a common kitchen cabinet unit foot.

Items required:

chipboard - I used offcuts

adjustable kitchen cabinet unit foot

2 x kitchen cabinet unit foot mounts

8 x wood screws

2 x wood screws

4 x 4mm screws

2.5mm drill bit

4.2mm drill bit

Drill

Saw

Paint, Brush & sandpaper

A suitable base board is cut to size, enough forward projection to make the monitor stable and enough rear projection to mount the foot base and the foot base is secured by screws.

After cutting a VESA mount board and drilling VESA spaced holes for 4mm clear fixings, a top plate from board is attached as the bearing for the foot.

Two foot supports are added to clamp the foot vertically.

Do not forget to counter-sink the screw heads on the Monitor side.

The two parts are fitted together using the foot clamps so that the top plate rests on the adjustable foot.

The foot is mounted upside-down to it's normal purpose; it can now be screwed out to lift the monitor to the exact height with the added bonus of allowing adjustment about the centre line.

This method using chipboard is rather crude so I would suggest metal plate, especially as a thinner backplane would help keep better control of the centre of gravity.

I was going to use a coned foot from my spares but it turns out I already used it elsewhere so I am now looking for a scrap of dowel to fit the centre of the foot and eliminate the foot clamps.

A central core in the foot would remove the limitations of the foot clamps and the centre of gravity problem; I am sure that you will do better!
