On my personal built computer i had recieved an update for Windows 7 one night and before i turned my computer off i updated it. when i woke up the next morning and turned it back on everything was big and magnified. I checked and the native resolution is set to standard definition of 1024X768 where my native was originally higher. I would have switched it but i no longer have the option to go any higher than 1024x768. I did a reset and did a system restore to a previous date and still nothing has changed. I am using a 22"inch Vizio tv as my monitor and i noticed that my tv wont get a signal until i am logged in and even then i need to turn off the tv and turn it back on to get any visual. Now even after i log in i still have no signal. Can anyone help me?
