IMPORTANT NOTE: This VESA mount adapter does NOT fit the the Acer R240HY Abmidx - the bracket only fits the Acer R240HY bidx. Always double check your monitor model number before ordering a VESA adapter. If you aren’t sure if this is the correct monitor mount, please ask! See the product description for a complete compatibility list and other VESA adapter options. If your monitor is not listed, it probably requires a different VESA adapter. | FITS SPECIFIC ACER MONITORS: This bracket is tested and guaranteed to work with Acer R240HY bidx (does not fit the R240HY Abmidx), G227HQL, G237HL, G247HYL, G257HL, G257HU, HA220Q, HA270, R221Q, R231bmid, R241Y, R271, R271Q Bbix, RT240Y, RT270, SA220Q, SA230, SA230 bi, SA240Y, SA270, SA270 Bbix, SB220Q, SB220Q bi, SB230, SB240Y Bbix, SB270, and SB270 Bbix. Acer has many similar monitor model numbers with additional letters and numbers -- these are not compatible with this VESA adapter. | MOUNT YOUR ACER MONITOR ON A STANDARD VESA MONITOR MOUNT - Though these popular Acer monitors weren't made with mounting holes, our convenient VESA adapter bracket makes your non VESA monitor mount to standard monitor VESA mounting patterns of 75x75 mm and 100x100 mm. Whether you're looking to mount it on a VESA wall mount, VESA monitor stand, or just get it off your desk, this bracket will let you connect your monitor in seconds. Works with double and triple (and more) mounts too! | EASY INSTALLATION - You'll be able to install this monitor mount adapter in less than 2 minutes with nothing more than a screwdriver. Remove the ENTIRE Acer monitor stand and insert our VESA adapter in its place. Then connect it right to the VESA stand. We've tested our mount extensively to make sure it fits your monitor just right. Use our handy cable slot to keep your cables organized. Slip them right through the slot and run them back along your mounting arm. | SATISFACTION GUARANTEED - If you have any problems with your mount, send it right back to us - no questions asked. Our bracket is guaranteed to fit your monitor, or your money back. Important installation note: the clip on the original monitor stand can be removed by pulling the entire stand out as one piece. If only the clip remains after you detach the base, screw it back together and pull it out as one piece. Our bracket inserts in its place.
