Can't get into store because of low resolution

I changed my resolution to 16:10. For some people, like myself, the resolution it chooses isn't the best your monitor can have. Leave UT, go to settings and on the end there should be a display config thing (I forgot the name but its near the end) and change your resolution there. It's trial and error, I went through about 3 different resolutions until the store opened.
Hope this helped!
