Important note: Does not fit any Ultrathin monitors such as S2718D, S2419HM and S2719DM. Check your model number very carefully. If the fourth digit in your model number is a 6 or 7 (ex. 2317, 2416, etc.), this VESA adapter bracket will not work. Tame the cable monster: Our handy cable slot is the perfect way to keep your cables organized. Rather than having them hang out the back of the monitor, just slip them right through the slot and run them back along your mounting arm. Easy Installation: You’ll be able to install the HumanCentric Dell VESA adapter in less than two minutes with nothing more than a screwdriver. Just remove the existing base and snap ours in place instead, then connect it right to the VESA mount. We’ve tested our mount extensively to make sure it fits your monitor just right. Satisfaction guaranteed: Our VESA adapters are guaranteed to fit the compatible monitors listed here. We put a huge emphasis on quality but “stuff” happens: a lost package, a damaged product, or monitor manufacturing changes. You can trust that if you have any issues with this mount, we will do our absolute best to make it right.
