![]() DisplayLink is working with Microsoft and graphics card vendors on a bug in Windows 10 with multiple internal GPUs that causes Windows 10 to use the less-powerful GPU for compute for an indirect display (e.g. One other possibility is worth exploring. I changed that, but SlingPlayer video still did not render on the UD-3900 monitors. The laptop’s built-in screen was not set as main. And as pointed out before, the Device Type of “Display-Only Display Device” The 2 monitors served by the UD-3900 a Chip Type of “unknown” and a DAC Type of “unknown”. On the problem XPS, I have 3 display adaptersĭxdiag shows the internal monitor as having a Device Type of “Full Display Device” and a Chip Type of Intel® HD Graphics Family. dxdiag shows all 3 monitors as having a Device Type of “Full Display Device” and a Chip Type of Quadro FX 1800 The SlingPlayer video works fine on that USB connected monitor. Device Manager shows only a single display adapter, a NVIDIA Quadro FX 1800. Not to confuse things, but I have a Windows 8.1 box (a Dell T3500) with a Startech USB to VGA adapter for a 3rd monitor. ![]() Looking at the device manager on that laptop, there is no additional display adapter for the WD15, onlyĭxdiag shows all 3 monitors as having a Device Type of “Full Display Device”Īnd a Chip Type of Intel® HD Graphics Family On the functional XPS-15, the true Dell docking station is a WD15. Have any thoughts on the difference in Device Types of “Full” and “Display-Only”? Again, the same monitor when plugged into a Dell docking stations shows “Full”, but when plugged into the UD-3900 shows “Display-Only” The same monitors that fail when plugged into the UD-3900 work when plugged into a Dell docking station. The 2 monitors that don’t work (plugged into the UD-3900) show a Device Type of “Display-Only Display Device”… It is not the physical monitor. dxdiag identifies all of the monitors that work as having a Device Type of “Full Display Device”. I’m also able to run SlingPlayer on a Windows 8.1 box, using NVIDEA drivers and DirectX 11, with Driver Model WDDM 1.2 The 2 displays attached to the UD-3900 where it fails to render the video use dlidusb2.dll and wudfrd.sys driversĪll monitors show the same Direc3D DDI and Feature Levels supported. The displays that do work use Intel drivers (igd…64.dll series) Using dxdiag, my Win10 system supports DirectX 12. Not ready to return your dock.ing station It’s a pretty cool gizmo less this one anomaly. The input to my Slingbox HD-Pro is Component Video or OTA.Īs a matter of fact, the HD-Pro doesn’t have an HDMI connection. I’m running Windows 10 Home Version 1709 OS Build 16299.125 ![]() My XPS-15 has both Intel HD Graphics 630 and NVIDIA GeForce GTX 1050 drivers.ĭell Update says I am running the latest drivers. I’m running the latest DisplayLink driver dated. This fails on both the UD-3900’s HDMI and DVI ports, standard display size with skin around video or in full screen mode. The only failure is with monitors that are connected to the UD-3900. I have also been successful when running SlingPlayer on monitors attached to a Dell’s docking station. Video is rendered fine if I run the SlingPlayer on the XPS-15’s integrated monitor or a monitor connected to the XPS-15’s its built-in HDMI port ![]() The video rendered within the SlingPlayer application is blank when using one of the monitors attached to the UD-3900 (ie using the DisplayLink chipset). This is a standalone executable, not Sling’s browser extension. I have a UD-3900 attached to a Dell XPS-15 via USB 3.0 port.
