In my workflow, I keep 4 displays in use. Three external monitors + the internal XPS 13 display Consequently, Video playback while supporting 6,912,000 display pixels was clearly taxing the sample XPS 13. It was also running on slower, hotter DDR3 memory. Although the i7 model, the sample 4K unit did not have the higher spec Intel Iris graphics chip. Creating a level of noise that some may find undesirable or even distracting. This made the XPS 13 run hot, and eventually the fan in the dock would kick in. Under what in 2020 would be considered to be trivial load, the Intel Graphics chip on the 2020 built was being taxed – you to 40% GPU utilisation. I did notice secondary issues when playing 720p video from YouTube on just one of the screens. Equally, using DisplayPort 1.2 in a daisy chain off of one of the DisplayPort connectors worked as well.Īll three screens loaded at 1920×1200 60Hz and there were no signs of lag or stuttering in 2D operations. Using 2x DisplayPort and 1x HDMI yielded the correct resolution. Using three identical Dell U2415 screens running at 1920×1200, it was possible to connect all three displays at 60Hz. ![]() The official documentation ( PDF) for the WD19TB is poorly laid out, unclear and accordingly is open to interpretation. The other was whether it was possible to use the three eternal screens plus the internal screen of the XPS 13 as a 4th display. One of the questions that I sought to answer was whether the dock was capable of outputting on 3x 1920×1200 monitors at 60fps. I had the opportunity to experiment with a WD19TB Thunderbolt dock while evaluating the new XPS 13 ultrabook. ![]() This article discusses using the thunderbolt dock with three 1920×1200 screens and four screens.
