That screen has been posted a few times. I even looked into it. Generally speaking, you get what you pay for when it comes to screens. I think that's an STN screen too. If you want more info on the screen, do a search on google for this model #MV7SC. I've yet to find where it says it's a TFT screen so that's what leads me to believe it's an STN screen.
If you're looking to watch movies, that might work. But for a computer and gps...it won't. Take a look at the LCD section and some past posts.
