My old hard drive died, and I finally got a new one for my laptop (XPS L501X). Before, my resolution was at 1366x768. Now, my resolution is at 1024x768, and I can't adjust it any higher. I have an NVIDIA 420 M, and I have reinstalled the drivers countless times in many different orders. I have also reinstalled the chipset drivers and wifi drivers. I have no idea why I can't adjust my resolution, and any help would be greatly appreciated.
