The WM-LG-LCK can fit VESA mounting patterns up to 600x400. But what does that mean? How do you know if it will fit your screen? It’s easy if you have your manual, a measuring tape, or the internet! Since you’ve obviously got web access, we’ll start with the latter. A quick query of the search engine of your choice can usually answer your question for you. Just be sure you have your monitor or TV’s exact model number as many manufacturers switch their mounting patterns from year to year. The VESA pattern should also be listed in the specs of your manual. If you don’t have the manual and can’t find the model number, or if you prefer to take a hands-on approach, you can calculate your VESA pattern yourself. Using a tape measure or ruler, measure the distance between the mounting holes on the back of the screen. Measure horizontally and vertically, not diagonally. There should be two numbers, both in millimeters. These numbers will be your VESA pattern.
