Windows 10: Multiple monitors and the two externals are sized wrong

I have three monitors set up. My Dell laptop running Win 10 with a 17-inch monitor and two identical Acer 24s. Pretty happy with the setup other than the following problem.The problem is in the multiple Monitor display settings the picture of the two external monitors are smaller than my laptop when they are actually larger. This makes moving windows from screen to screen and the mouse movements well let's just say not user-friendly. Before someone chimes in and says change the resolution like the other people that asked questions my laptop has automatically selected the recommended highes

Ongoing Resolution Issues With Multiple Monitors

Hello,

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.

Problems

• Refer to this gallery for images citing the specific resolution issues (apologies for the compressed/poor quality): Resolution Issues
• 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:

• 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.

Hardware/Specs:

• 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 - 20.19.15.4483) and NVIDIA GeForce GTX 960M (Driver - 21.21.13.757) - the NVIDIA driver was disabled, which helped improve some of the problems, but not all of them.
