2. Select key starting with SIMULATED, then child key 00
3. Change the decimal value of PrimSurfSize.cx to the desired horizontal resolution (i.e 1920)
4. Change the value PrimSurfSize.cy to the desired vertical resolution (i.e. 1080)
5. Change the value Stride (for 1920x1080 this is 7680: ((1920 * 32 + 7) / 8))
6. Select the child key of 00, also named 00, and change ActiveSize.cx to the same horizontal resolution value above

It will change resolution from 800X600 to 1920x1080 or your can put the resolution as per your need.
