Hi I have been experiencing a problem with my HP HDX 16 Laptop running Windows 7 Home Premium. I have had it connected to a Samsung HDTV as an extended monitor using an HDMI connection and up until a couple months ago everything was running fine. What has been happening is that whenever i restart my computer for whatever reason, once it boots up my HDTV shows the login screen and approximately 30 seconds later, the screen defaults back to my laptop screen. This forces me to login and manually change the display settings back to extended desktop etc...

I have determined that both the HDMI and VGA connections experience the same issue so it is not isolated. I am afraid that my graphics card could be damage or becoming damaged, but i am not sure i believe this at this moment.

If anyone has any ideas as to why my display settings could be resetting themselves upon restart i would greatly appreciate it.

thanks.

The symptom you described — the Samsung TV shows the Windows login screen, then about 30 seconds after boot the display reverts to the laptop panel — is important. It means the TV is detected during early boot but something in the user session is changing the display state. Since already ran Norton and Malwarebytes and suggested drivers (which you tried), focus on isolating a user-mode/startup change, switchable-GPU behavior, or a corrupted driver/profile rather than a simple cable fault.

Try these targeted tests first: create a new local user account and see if the behavior repeats (quick way to check if it is per-user). Boot to Safe Mode and then to a clean boot (msconfig: disable non-Microsoft services + startup apps) — if the problem goes away, re-enable items in halves to find the culprit. Check Event Viewer (System log) for display/driver errors at the time the screen flips, and open Device Manager to see whether there are two adapters (integrated + discrete) or repeated monitor entries. As pointed out, most laptop GPUs are not user-replaceable — detecting two adapters points to switchable-graphics issues rather than a removable card.

If a startup app or driver-reset is the cause, a practical workaround is to force Windows to re-apply "Extend" at logon using the built-in display switcher. Create a scheduled task that runs at logon and runs:

C:\Windows\System32\DisplaySwitch.exe /extend

If driver instability is suspected after the tests, do a clean driver uninstall (Safe Mode) and reinstall the correct GPU package for your HDX, and consider an OEM chipset/BIOS update (backup and follow HP instructions). Prioritize: (1) clean boot/new user test, (2) check Event Viewer/Device Manager, (3) scheduled-task workaround, (4) clean driver uninstall/reinstall and BIOS update, (5) contact HP support if hardware failure still seems likely.

image reseting itself cause the graphics cant support the settings try to reset the screen resolution,, 1024 x 768 or higher until it is compatible and not resetting anymore....

Try using another computer and see if there is no problem your laptop graphic card could be old and need to be change

Mine can but i am not sure about his

so, you find out what laptop he has ,look it up ,and then advise to change it if its changeable

If settings are changing the most likely cause is an infection. What antivirus and antimalware software do you have and have you scanned with them recently? If so, what was found by them?

Member Avatar for jingda

This problem you are facing is common but are often solve when they plug in and out. Somethins is wrong with your laptop. Do a scan first like what Rik suggested. If you have no antivirus software we can also recommend you some
