You need Toshiba to tell you what other drivers and apps to install to finish this up.
I have a 64 bit Toshiba Satellite running Windows 10, and I stripped it down and did a clean install some time ago. However, last week my screen resolution went to 1024 x 768, and with this wide screen everything is stretched. The issue is that when I go to advanced display settings the only resolutions available are 1024 x 768 or 800 x 600. The weird thing is that there was an automatic update two days ago, and it was fixed, and many resolutions were available. However, I woke up today, started the laptop, and again the screen is stretched, and only the two resolutions available. Any help would be appreciated.
