HP Envy Game resolution problem

[aoi-tenshi]

Hi

I am having trouble with my Envy 17 after installing BlazBlue, I am having trouble with games resolution all games run perfectly fine but in a 640*480 resolution. Games that used to run perfectly in a full screen reso now only run in 640*480. Not long ago that I discovered if I connect the laptop to the HDTV Bravia I have all games run in full reso again. I tried uninstalling the drivers and restarting the laptop and reinstall the original drivers it didn't work. I tried installing the newest drivers in hope it will get fixed but it didn't. I am out of options ..... the only that I have in mind is to factory reset the laptop and im not even sure that will solve the problem... can someone help me please with a solution that might work?? thanks in advance.

I have these photos which I took that might help you recognize the problem better thanks again.

I just wanted to add that scaling options in the graphics properties can't be modified. I was messing around a bit with the options and I lowered my laptop's resolution to 800*600.

right click on desktop -->Screen Resolution --> Resolution 800*600

anyhow after doing that I went back to the scaling option in the graphic properties

right click on desktop --> "1st choice" graphics properties --> My Built-in Displays "you have to be in advance mode"

then I saw that the scaling options were changeable so I changed it from Preserve Aspect Ratio to Full Screen.

Apply the changes and got the problem fixed for some of the games. So its half fixed some games started running on full screen and some didn't... please any help? i've been suffering from this annoying problem for a month now.. thanks again people.
