I can no longer increase the screen resolution above 1024 x 768

[idata]

I have a Dell Inspiron N5010 15R, until I received an update from Windows Update Video "Intel Corporation - Display - Intel (R) HD Graphics" (Optional), I could use 1366 x 768, but after this could no longer update.

I've tried back the restore point (not returned, the Windows is not allowed), install a newer driver video adapter, go back an older driver, install the driver available from Dell, try update again via Windows Update, but all attempts were unsuccessful.

I contacted Dell support via chat, attendant advised me to run the Dell Diagnostics boot time, was not accused of any problem hardware.

Any ideas what can I do to solve the problem? I'm not willing to take that format and/or make a restore cause of a driver from Windows Update.

Thank you in advance.
