Advent Vega trouble

Hi All

I have just got myself the Advent Vega which i know is at the bottom of the range for tablets so not sure how many of you might be able to help me. The problem that im getting is when i play my online poker and certain app games i cant see all of the screen as it seems to be to big for screen. Its alomost if the resolution is set to high. The action buttons for example for my poker E.G the check , fold or raise buttons are at the bottom right of the screen but when i play on my tablet i cant see them as everything is so big and they dont fit on the screen. I hope this makes sense and if anyone can help i would be very grateful as i have looked into my setting and can find no help. Also the manual is very basic and also offers no help. Many Thanks.

this might not give you your answer but have you tryed pinching the screen sorry if this doesn't work i just saw your post and it was just an idea!
