Since Google Chrome version 54, it now detects the DPI settings on the computer
and scales the web browser accordingly.
Previously, Google Chrome did not pay attention to the system’s DPI settings,
but now it does and that is the root cause of the large interface issue.
If the DPI is set to more than 100 percent in the system, this would give the effect of "zoom-in". In most cases this is what an end-user would wish,
but not a Web developer.
To force Chrome to ignore the system DPI setting, the solution is to launch
Chrome with one of the following parameters
(there are two possibilities depending on the Chrome version and OS):
/high-dpi-support=1 /force-device-scale-factor=1
--high-dpi-support=1 --force-device-scale-factor=1
--high-dpi-support=1 --force-device-scale-factor=1
or/high-dpi-support=1 /force-device-scale-factor=1
