Windows 10: Resolution Issues & BSODs After Re-Connecting Laptop to External Disp.

    Resolution Issues & BSODs After Re-Connecting Laptop to External Disp.


    I am looking for help, as I have been having some resolution issues with my extended monitors for quite some time. There are a large number of problems that range from BSODing shortly after re-connecting my docked monitors on a regular basis to having constant annoyances with sizes on screen. I have tried and searched for hours and attempted every applicable resolution, but I haven't found a correct solution. While I would love to resolve problems with resolution, the BSODs after re-docking are my primary problem.

    • Refer to this gallery for images citing the specific resolution issues (apologies for the compressed/poor quality): Resolution Issues - Album on Imgur
    • BSOD after re-connecting my laptop to either docks (takes about 15-20 minutes and gives multiple error messages)
    • Very inconsistent font sizes and sizes associated with Windows and file explorer
    • Applications, both DPI-aware and non-DPI aware, have scaling issues

    Things I have tried/notice:

    • Updated drivers, BIOS, firmware, software, etc.
    • Ran the various Windows commands to check for errors (sfc /scannow, dism, etc.)
    • Swapped wires and re-seated connections
    • Adjusted refresh rate on external monitors to 59 and 60 hz
    • Adjusted resolution on primary monitor to 1920x1080 to match both external monitors (while this is an undesirable solution, it did help some problems and helped address many of the sizing problems, especially with file explorer)
    • Used custom scaling instead of standard resolutions
    • Installed Samsung drivers for monitors
    • Reset the monitors to default settings
    • As an aside, the resolution problems disappear entirely on the external monitors if I set them to mirror the primary monitor. However, as soon as I extend the display, the resolution problems appear. I do not want to mirror my monitors, but I don't understand why a mirror would correct the problems.
    • 9 times out of 10, the BSODs will occur after re-connecting my laptop to my external displays. However, if I reboot my laptop immediately after reconnecting to the monitors, there will not be a BSOD.
    • The BSOD gives three or so different errors, ranging from "Critical Process Died", "Memory Management", Exception Not Handled, etc.
    • Additionally, often if my computer goes from Lock Screen -> monitor off following an idle time, the monitor will not "wake up" or render to a usable state. I have attempted to wait, push buttons, close the lid, re-connect/disconnect monitors, etc. The only solution is to perform a hard reboot.


    • Dell XPS 15 9550 Laptop
    • Primary Monitor: 3840x2160 (also 1920x1080)
    • Two Secondary External Monitors: Samsung S27E510 (1920x1080)
    • OS: Windows 10 Version 1607 - I have had the same problems with multiple builds. I also had the same problems on Version 1511.
    • Dock 1: USB-C hub to allow for a second HDMI external monitor, in addition to the other secondary HDMI external monitor, which is connected directly to the laptop
    • Dock 2: Thunderbolt TB-15 (this was installed a few months after using the USB-C hub, but did not change any of the issues)
    • Video Card/Drivers: Intel HD 530 (Dell Firmware - and NVIDIA GeForce GTX 960M (Driver - - the NVIDIA driver was disabled, which helped improve some of the problems, but not all of them.
