Si8000m / Si9000e font oversized display scaling
Application Note AP636 

Some Si8000m and Si9000e customers have reported the issue below with respect to font scaling:

Currently, after the customer's laptop installs Si8000m and executes it, the "OK" button font overflows the control as shown in the graphic below

The large fonts appear in the Si8000m user interface and overflow most of the Si8000m controls – see the screen shot below.

This occurs even when the screen resolution (System Settings | Display | Scale and Layout is set to normal.).

The symptoms described above are normally caused by the following:

During installation, Windows installs a larger font set which is 125% or 150% of the normal size. If you then choose to go back to the standard font size (100%), Windows will keep some of the large fonts even though everything else is adjusted for standard fonts, causing some programs to display incorrectly as the DPI is too big for the window size.

The issue can be resolved via the steps below.

(Exercise caution when editing the Registry – you may have to get the IT department to back up and grant access to the Registry)

1.Open the Start menu and type regedit and press Enter.
2.Locate the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
3.Find the value MS Sans Serif 8,10,12,14,18,24
4.Change from SSERIFF.FON to SSERIFE.FON
5.Find MS Serif 8,10,12,14,18,24
6.Change from SERIFF.FON to SERIFE.FON
7.Find Courier 10,12,15
8.Change from COURF.FON to COURE.FON

Restart Windows.
