The connection is made from S元 -> Lenovo USB-C Dock Gen 2 -> Displayport to Mini Displayport on the Dell U2715h. Just a heads up and if someone from Microsoft sees this maybe talk to the Surface team:Īfter installing the January 2020 driver and firmware updates for Microsoft Surface Laptop 3 (Intel), my machine detected my external monitor (Dell U2715H) as 640×480. Surface Laptop 3 (Intel) issue with DP1.2 monitor after installing January 2020 updates And there is another forum thread in Microsoft Answers with such a bug description. Since 2 February 2020, other users have confirmed this bug. I tried the displayport of the monitor with other computers and it's working fine.
Any tips or tricks to get it working again? For some reason it shows 'Flat Panel, 640×480' when using display port, but the samsung drivers when using HDMI. If I plug in the HDMI, it works, but, resolution is not that good like it was on the Displayport. Which is no good with a 49 inch Samsung monitor. Today after I updated my surface pro, my monitor is stuck in a 640×480 resolution. Monitor stuck on displayport with 640×480 In Microsoft Answers, an affected person describes the error pattern in this forum post as follows:
