Click the OK button and reboot the computer. Select Selective suspend in the menu and set the value to DISABLED. Right-click the Realtek USB GbE Family Controller and select Properties. Their CPU acceleration is however a limiting factor for 3D or high frame-rate use. Open Device Manager (Right-click the Windows Button and click Device Manager). In most 2D workflows, it offers an acceptable route to 4 screens. Had I been able to test with an external GPU enclosure, it likely would have been possible to use all 4 screens via Thunderbolt.Īlthough the use of a USB display source such as the or is undesirable. Plugging in my USB DisplayLink adapter allowed a 4th screen to appear as normal. This is likely a limitation of the Intel Graphics chip and is nothing to do with the. Even with all 4 screens running a sub-native resolutions, the Intel graphics driver refused to allow 4 screens to be used. I repeated the test after lowering the 1920×1200 resolution of the three external monitors to 1920×1080. It was possible to have any combination of 3 screens enabled, but attempting to enable the 4th would iteratively disable the first screen in the display list. Despite this, it was not possible to use the three WD19TB external screens plus the internal display. I do not usually run the built-in panel at its native 3200×1800 as the mismatched Windows font scaling doesn’t play nicely with non-UHD external screens. So was it possible to use the WD19TB with four screens? My main activities are present on the external screens, while I will keep tertiary activities such as email on the lower, built-in screen. 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. It's the only analog signal type out of all of the types discussed here, and as a result it looks noticeably worse than the other digital signals, especially at 1080p resolution.This article discusses using the thunderbolt dock with three 1920×1200 screens and four screens. But honestly, if at all possible, try to stop using VGA. You cannot convert HDMI or DVI sources to VGA unless you find a so-called 'active' that has a embedded into it that will perform that conversion, but those are less common and more expensive. You can also go the opposite direction up to 1080p resolution.

If you have an HDMI output on the dock, you can convert that to DVI for the display. If you're using your display's DisplayPort input, it must receive a native DisplayPort signal. However, you cannot send any non-DisplayPort output into a DisplayPort input. The reason is that DisplayPort is the most flexible type of output available (and also the most capable in terms of max resolution). If you have a DisplayPort or Mini-DisplayPort output on the dock, you can buy adapters that will convert that output connector to the opposite DisplayPort 'size', DVI, HDMI, or VGA. It's more common to reference adapter/cable directions from the source to the target since that's the direction in which the signal flows - so in this case, that would be indicating the dock connector first and then the display connector.
