Depending on the size and application mounting a monitor can be difficult. Careful planning and preparation should be done when looking at mounting options so that the monitor will fit properly into the application and be mounted safely.
Large LCD monitors can be very heavy and mounting it should be done carefully so that it is securely fitted in place, there are a wide range of monitor brackets that can support large monitors and displays but always double check the max loading weight for the bracket.
Another thing to always look out for is to always check that the bracket will fit your monitor. Most monitors have VESA mounting holes on the back, some vary in size but they are usually 100mm VESA holes depending on the size of the display, the larger the monitor usually means larger VESA holes.
To the left is an example if how a small 17″ LCD display would be mounted using the VESA holes on the back of the display and also an move-able arm mount.
As you can see from the images 4 screws are used to attach the arm mount to the back of the monitor using the 4 VESA holes. As this is only a relatively small monitor weight wouldn’t be a big factor and this arm bracket is easily able to hold the monitor in place.
