This chip is used to build a number of Adapters. For example DL-6950 chipset has 2 outputs, the maximum resolution is 3840x2160 (UHD) if both video outputs are being used. Lucky we have displaylink on the market, they make chipsets that work like external video cards. Thus, even having 4GB of video memory and 'Nvidia Quadro' on board, the overall configurations still limited to the number of screens that the 'master' video card can provide. So the 'master' sends all the heavy calculations to be processed by the 'slave' and only displays what is returned by the 'slave'. Intel HD Graphics 630 - is a 'master' in this context. At 40 G b/s, it is the fastest port available on a computer today 8x faster than USB 3.0 and 4x more video bandwidth than HDMI Transfer a 4K movie in less than 30 seconds Back up a year’s worth of continuous MP3s in five minutes Plus, connect to any display, Thunderbolt, or USB device USB 2.0 USB 3.0 USB 3. Nvidia Quadro M1200 - designed to have no video outputs, it works like a 'slave'. In my case it is Nvidia Quadro M1200 with 4Gb of video memory and Intel HD Graphics 630 with shared memory. It is a new trend, new laptops these days have kind of 2 video cards. My notebook (Dell Precision 5520) is not the only one suffering from it. So if I use 3 external displays with my docking station, my laptop displays is getting turned off. My notebook (Dell Precision 5520) can only run 3 displays. It was actually more than FullHD, it was 1920x1200, thus the Thunderbolt-3 can do it.īut there was a catch. It allowed me to utilize 3 FullHD displays just fine. I bought Dell Thunderbolt Dock (WD19TBS) it worked fine.
