Small issue with Dell XPS 15 9550 screen
On the bottom left side of the screen there are two small pixels glow more than the others, is that normal?
Usually these two pixels appear clearly when you look from the left side on white backgrounds.

Hi MONY960,
Have you tried cleaning the screen for any smudges or specks of dirt? Are the pixels seen from the time the system is powered on? Are they persistent or do they appear randomly? When did the issue start? When was the system purchased?
Check if the pixel is seen on the following:
1. Restart and press f2 on startup to enter BIOS - check for the pixels
2. Run the LCD bist - Turn off the system and press and hold the "D" key + power button to turn on the system and it should run the LCD built in self test - see this link for more info - http://dell.to/1SkXNrG
3. Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
4. Connect an external monitor and check if the pixels are seen on both the displays.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.
