# [Pain and Suffer inside: Displaylink Adapter](https://psychip.net/entry/pain-and-suffer-inside-displaylink-adapter) ## January 31, 2014 as mentioned on my [recent tweets](http://twitter.com/psychipdotnet), was looking for a low cost multi-display solution about couple weeks. gaming oriented gfx cards already providing this feature but they costs as a new computer and requires gigantic power supplies. that will an unnecessary investment. finally i purchased an usb [displaylink](http://www.displaylink.com/technology/dl-3000/) adapter with a fast decision. i supposed its an gfx chip which can communicates with mainboard via usb port. **..But it's not** It creates a virtual desktop on your system by using software and captures realtime video from it. then device receives this video with 50~250ms delay. i don't sure that's applicable in commercial industry but it's terrible idea. **Suffer begins** Maybe their certified products working without any trouble but i did my second mistake by purchasing an unknown chinese brand with high price. its getting warm on first usage and resets itself due to overheating. and i decided to use it by replacing heatsinks instead of refund. this time heatsink melts its plastic cover, and i installed a small fan into it. wtf. this is madness. **The Cure** ofcourse i didn't use it due to its noise, i researched more and finally found the [Sapphire HD6450 Flex edition](http://www.sapphiretech.com/presentation/product/product_index.aspx?cid=1&gid=3&sgid=1086&pid=1414&psn;=&lid=1) it uses an unique technology called "Flex" to get three displays same time. that's exactly what i need but its obsolete a little bit and hard to find in local market. then found on someone's ebay store later. after the two weeks, i received item, installed it to my mini-itx case and sent that usb-crap to trash. if you're planning a similar screen setup, stay away from displaylink devices.
