you can try this -
you can try to manually override your max res and try it again -
if your screen is similar to mine and it can do 1680x1050, try changing this-
$Pref::Video::Mode = "1680 1050 true 32 1680 0";
if yours looks like this -
$Pref::Video::Mode = "980 551 false 32 980 0";


I'm pretty sure it is in pref.cs
