touching the bracket may deviate at most ±1 mm from complete flatness. The screen manufacturer should warrant that filling the provided holes in either the horizontal or vertical edge (at user's choice) with the specified screws will be able to hold the screen in any direction. The bracket manufacturer should warrant that the bracket can carry the advertised weight when using a few of the included screws (but at least the 4 corners) as would be needed if those were standard industrial grade screws. The end user or contractor should warrant that the wall, ceiling, floor or wherever else the bracket is hung can handle the load safely and within the local building code. More details can be found by purchasing a copy of the standard itself, including rules to ensure cables don't prevent using the mounts. Common deviations from variant F In practice, many screens that almost comply with part F of the standard deviate in various minor ways, and most brands of compliant brackets are designed to handle these deviations with little or no trouble for the end user: Non-square patterns, such as 600 × 200 mm and 600 x 400 mm and 800 × 400 mm. These were apparently permitted by the version 1 (2002) standard. The labeling for these may have been "MIS-F, width, height" e.g. "MIS-F, 600, 200" for 600 × 200 mm. A somewhat strange pattern of 280 × 150 mm. Various protrusions on the screen extending a few millimeters further back than the mounting surfaces. Compliance Manufacturers of FDMI compliant devices can license the use of a hexagonal "VESA mounting compliant" logo. Many compliant or almost compliant devices do not display the logo, as is reflected by the absence of most key vendors from VESA's own public list of licensed manufacturers. Of the members of the standard committee (Ergotron, Peerless Industries, HP, Samsung, Sanus, ViewSonic and Vogel), only Ergotron is on the list. As mentioned above under variant F, there are many almost compliant screens on the market, and some of those use the "VESA" name loosely to refer to their similar mounting patterns.
