yes , its full hd , tv's dont have a higher resolution ... its showing no support mode because ur trying something other than 1920x1080 , which is full hd . ull also need a good wire for vga because interference problems will cause unclear picture .
do you have intel or nvidia graphics ? for nvidia go to nvidia control panel , set up multiple displays , detect display , and in dual view mode , change the resolution to 1920x1080 .
Sorry i've been so busy to get online to reply to your post. I still got a problem because my computer doesn't have a resolution as high as 1920x1080. It does show up on 40" Sony tv has full hd. Would it make it a difference between 40 and 60 inches t.v? Do you have a wire recommendation?I use a 50 foot wire.
