Excel Display Problem on External Monitor

We have a Dell Precision 5520 laptop connected to a Dell TB16 USB-C dock and two Dell P2715Q monitors connected to the dock. One monitor is connected via a standard DisplayPort cable. The other is connected via a DisplayPort-to-miniDisplayPort cable. When Excel (2016 64-bit) is opened in full screen on one of the external monitors, sections of the spread sheet are masked by black, grey, or white spaces of varying sizes. We don't have the problem if we run Excel in a window - as long as the window doesn't exceed a certain size (about 3/4 of the monitor screen). We have done the following troubleshooting steps:

- Updated drivers for the Laptop and the dock
- Booted into safe mode with networking and tried to run Excel Excel wouldn't run because the license couldn't be verified.
- Uninstalled and reinstalled Microsoft Office 2016 64-bit
- Experimented with display resolutions with the following results (We didn't test any resolution below 2048 x 1152):
** The problem exists with the following resolutions:
### 3840 x 2160 (This is the recommended resolution - by Windows 10 - for the laptop and external monitors)
### 2560 x 1600
### 2560 x 1440
** The problem went away at the following resolutions:
### 2560 x 2048
### 2560 x 1920
### 2048 x 1536
### 2048 x 1152

Any suggestions?

Try the native resolution of each screen . Then on the laptop screen and assuming Windows 10 Creator Update, you can scale the display text to what works for you. I use 125% on my own ThinkPad. This worked in another thread where I participated.

Thanks for the suggestion, but 3840 x 2160 is the native resolution for both the laptop and the external monitors. The text scaling is currently set to the recommend settings.
