As with the linked instructable, I was looking for a way to hang my side monitors on the wall to free up some desk space underneath. I already have 2 22" monitors mounted using VESA swivel arm mounts but they cost me over $80 for the pair, even when ordering online. Since the 2 monitors I wanted to mount directly on the wall were smaller (and less expensive) 17", I thought something homemade would do the trick.
Step 1: The Tools/Materials
Aside from the system, you will need something to fasten the mount to the wall. I didn't want to have to worry about finding a stud and hoping it was near where I wanted to put the monitor, so I grabbed these special screws for mounting things in drywall. They're rated at 50lbs each, and since my monitors are cheap I'm not worried about them falling (not that I think they would).
Lastly, you'll need bolts to attach your monitor to the picture hanging bracket, and screws to attach the bracket to the wall. The whole set up set me back about $14.
As far as tools go, the plastic mounting screws are self tapping, but I drilled pilot holes to be safe. A cordless drill does wonders here, and a vice helps for punching holes in the picture mounting kit.
Step 2: Prep the Monitor
Step 3: Modifying the Hardware
Once you have the holes drilled, go ahead and screw it on. I used washers for added support, but they probably aren't necessary.
Step 4: Mount Point
Step 5: Wall Mount
Drill the holes, put in your mounting system, and screw the bracket to the wall.
Step 6: Finish Up
I really like how this worked out, the system is very forgiving horizontally, if you need to slide it over to the left or right you can very easily, and they also come off very easily as well. Hopefully this will help others looking for a cheap alternative to more expensive VESA mounts.
