Dell XPS 15 9550 BIOS Upgrade Information Request

This issue refers to a Dell XPS 15 9550 the configuration of which is listed at the end.

I am attempting to run a user application but experience display and control issues.

Another user of this application on a Dell XPS 15 9560 has resolved the issue by upgrading to BIOS Version 1.6.2, release date 11/12/17, filename XPS_15_9560_1.6.2.exe. The latest BIOS release for the 9550 appears to be version 1.3.0 but this does not resolve the  issue.

Does anyone know:

  1. What was included in the update that might have fixed the issue.
  2. Whether a corresponding update is going to be ported to a 9550 BIOS and if so when.
  3. Whether version 1.6.2 is OK to apply to a 9550 (I suspect not)

1.  Whatever release notes there are will show up on the web page with the download.

2.  Unlikely - the 9550 is an end of life system.

3.  No way - DO NOT force-flash the 9560 onto a 9550 system.   You'll wind up with a dead mainboard.

If the problem you're having affects just one application, you'd do better to check with its publisher -- chances are it's the application that needs an update -- not the system.
