Custom Resolutions & multi-monitor tweaks
Update 2020/12/23: Use the CRU tool to set custom resolutions since Intel has disabled this feature on newer versions of the command-center app. Some folks may be able to get the Dell.com version of the Intel Command Center to re-enable custom resolutions on the laptop LCD panel but this may not work for all users.
Intro
I received a few comments about folks having difficulty getting custom resolutions working with the latest Windows 10 updates and Intel’s newer DCH/UWD drivers. Below are steps and a lengthy guide on how to get it working and fully optimize your workstation. For a deeper explanation on why custom resolutions are helpful for so many office applications and games, especially with multiple screens, see these older articles:
Why custom resolutions?
The approach allows setting a different resolution for the Surface Laptop screen than the native LCD panel resolution to:
bypass problematic dpi-scaling built-into Windows 10 yet make all text and UI the same size across screens of various pixel density (dpi) and physical size
make dragging windows across the threshold between screens seamless without distracting jumpy artifacts
minimize the likelihood of your mouse cursor getting “lost” in the corner between two adjacent screens of different size/resolution
improve gaming performance due to fewer distinct pixels to process
get rid of letterboxing or black bars which appear when setting the built-in Windows resolutions in the control panel
optimize refresh rates
There are potential side effects with this approach for older software and games. But it is a reversible modification (just switch resolutions back) so there is no risk.
For folks using Surface Pro, Surface Book, Surface Go, and similar high-performance laptops, the best resolution choices tend to be either:
a resolution that most closely matches the pixel density (dpi) of your primary external monitor (see tables in the appendix) OR
1/2 the native resolution of the Surface screen
Custom resolution steps (100% reversible)
Un-dock your Laptop so that no external monitors are connected
Install Dell.com version of the Intel Command Center:
enable side-loading or developer mode in the Windows settings app
uninstall all previous versions of the Intel command center app
download the Dell.com version of the Intel Command Center app
double-click the .exe file and select “extract”
right click and create a new folder named “dell”
select the newly created “dell” folder a folder and proceed with extraction or you can use the 7-zip tool to extract
once extracted, right-click the 18c529d76f9946b3b73eac52ac582bd5.appxbundle file which will reveal an “install” option. Click install
This app works with *most* Intel GPU drivers automatically installed when upgrading to Windows 10 1903 or later. If the app fails to install or gives an error when running, try installing the latest intel.com GPU driver applicable to your PC then reinstall the command center app.
Add your custom resolution(s):
open the Intel Graphics Command Center App
click Display
If a “Custom” button is visible, click it. Otherwise click on the drop-down box showing the current screen resolution then scroll down to the bottom of the list and click “Custom”. If both options are missing, you’ll need to use the CRU tool instead
In the Custom Resolution screen, enter your preferred Width and Height. such as [1080 x 720], [1200×800], [1440×960], etc.. Choose “60” for refresh rate, leave Timing Standard to “GTF”, and Underscan to “0%” unless you have a particular reason to change these.
Users who want to run a higher refresh rate than what windows default to should choose the “CVT-RB” timing standard.
Surface users can refer to the tables in the appendix to determine the optimal resolution to use.
Click “OK” then “Yes”
Reboot
Dock your Surface and ensure all external monitors are recognized.
Set Primary monitor – In the Windows Display Settings Control Panel set the most frequently used external monitor as the “Primary” monitor:
Open Settings app, then “System” then “Display”
Click on the numbered rectangle representing your preferred external monitor
Scroll down and ensure “Make this my main display” is checked
Move the number boxes representing the physical monitors into the appropriate relative locations
Switch resolutions – In the Display Control Panel, choose the newly created custom resolution as the resolution(s) for your screens.
Open Settings app, then “System” then “Display”
Click on the numbered rectangle representing your desired screen
Under “Display resolution”, select your custom resolution
Notes
If you have issues with Windows periodically forgetting your monitor arrangement, there is a tool from Microsoft to clear the Display Topology cache so that you can start fresh.
Some applications, (notably those from Adobe) may misbehave during the dock / un-dock transition and text or UI elements may appear the wrong size. Re-starting the application will typically resolve the issue.
Depending on the specific generation of Intel GPU and LCD panel, running a lower resolution may reduce text clarity. Newer panels and GPUs have much better scaling approaches so this is not an issue.
Like previous Intel tools, some resolutions are impossible to set, or when added, the resulting resolution is off by a few pixels. For example when attempting to set 1500×1000 on a Surface Book (exactly 1/2 the resolution for Gaming), the tool may report back 1504×1000 or 1496×1000 instead. This appears to be an issue with the timing controller chip (TCon) used on the panels and how it interacts with the Intel driver software. There should be no visible artifacts from aliasing caused by the 4 pixel difference so it is safe to run games and applications at this slightly different resolution. If you find differently, please post screenshots of any issues you have. The 3rd-party “CRU“ tool may be helpful to set additional resolutions that the Intel tool is unable to set.
Many folks have difficulty using “5K” 5120×1440 ultrawide monitors. Please see the 5K article for a solution.
Appendix: Microsoft Surface Custom resolution guide for multiple monitors
Unlike most other laptops, Microsoft Surface devices use the 3:2 screen aspect ratio. The purpose of this resolution guide is to help you choose a custom 3:2 aspect ratio resolution that works best with your external monitor. Because there are so many monitors to choose from, the list may look daunting at first, but you really only need to know one number: the dpi of your primary external monitor and I’ve collected those for the most popular monitor sizes below.
Monitor sizes that match Surface devices particularly well are in bold. If your particular monitor size/resolution is not listed and you have problems customizing your workstation, let me know in the comments.
How to use the lists/tables
Find your primary external monitor size in Appendix A and note the dpi. For example, if you have a 24″ 1920×1080 monitor, it is 92dpi
Find a resolution in the list pertaining for your Surface device that closely matches the dpi of your primary monitor. For example, if you have a 15″ Surface Book 2, a closely matching resolution is 1080×720 (wow what a low resolution! – don’t worry though stick with the process…)
Use the Intel Command center app to set the resolution while your Surface is docked.
For example, when docking a 15″ Surface Book alongside a 24″ 1920×1080 monitor, the Surface Book will be running at 1080×720 resolution. All UI and text across the screens will be of very similar size making it much easier to use.
A. Common monitors sizes sorted by DPI class
96 DPI class (most 1080p and 1200p monitors)
Windows defaults to 100% scaling. Text is a little larger than smaller monitors with same resolution and well suited for folks with glasses or who prefer a further viewing distance, but who do not need other vision aids.
21″/22″ 1920 x 1080 – 103dpi (Good for Pro4-Pro7+)
23″/24″ 1920 x 1080 – 92dpi (Good for 13.5″ Book models)
24″ 1920 x 1200 – 94dpi
27″ 1920 x 1080 – 82dpi
29″ 2560 x 1080 Ultrawide – 96dpi (Good for Pro8/ProX/Pro9)
30″ 2560 x 1600 – 100dpi
31.5″/32″ 2560 x 1440 – 93dpi
34″ 2560 x 1080 Ultrawide – 82dpi
120 DPI class (most 1440p monitors)
Windows defaults to 100% or 125% scaling

49″ 5120 x 1440 Ultrawide – 108dpi (Good for 15″ Surface Book 2/3
144 DPI class (large 4K/5K monitors)
Windows defaults to 150% scaling
31.5″/32″ 4K – 140dpi
40″ 5120 x 2160 Ultrawide – 139dpi
168+ DPI class (smaller 4K/5K monitors)
Windows defaults to 175% or 200% scaling

Whew, that was a lot. When will Windows be smart enough to just do it right automatically?
