Well, it is so confusing monitors. it took some digging, but it looks like the Samsung MU6300 has a pretty special screw requirement. For a different model of Samsung, they need a M8x45mm course threading (1.25mm/thread). The 45mm is an estimate, but it is definitely deep.
The mounting doesn’t have any of these screws so off to the hardware to store to get a set.
M8Also to mount a consumer TV to a monitor arm, you need a 100mm Vesa to 400mm Vesa plate adapter and of course the screws are wrong again. We use the AmazonBasics (a steal at $99 IMHO), but you need something that attaches properly.
Here is exactly what you need to tie in:
- Samsung MU6300 43″ monitor. A steal at $550 or so π
- Vesa 400mm to 100mm adapter plate. About $20 on Amazon, this is because TVs have a standard 400mm x 400mm set of screws for mounting, but PC monitor arms use the smaller 100mm x 100mm size.
- AmazonBasics Monitor Arm. You can ignore Β the warnings about it only working on monitors 27″ or less, it works fine on this 43″ mainly because panels are so light these days. This is a terrific arm and looks like an OEM version of something costs 2x as much.
Then you will be short hardware to mount it, you need comes in a Long Monitor Wall Bracket to TV Bolt package for about $11.
- M8 x 1.25mm/thread (the so called course threading) in the 30mm length. Four of them.
- A spacer or bushing as the adapter plate cannot be flush agains the monitor. The perfect dimensions are 5/16″ Inner Diameter, 1/4″ long, 5/8″ outer diameter.
