Bracket allows you to mount GBS-8200 'CGA/EGA/YUV to VGA adapter' on back of LCD display with VESA 100 mounting pattern.  Holes for VESA mount pattern are designed to be through-hole clearance for M4. Holes for mounting GBS-8200 are designed to be tapped M4x0.7. In a pinch, they could probably be opened up a bit (~3.8mm) and tapped with the mounting screws. Alternatively, smaller and/or self-tapping fasteners might be a easy solution.  The GBS-8200 has applications for converting video signals from arcade machines, old consoles and personal computers or legacy machine controls. YMMV.
