I've downloaded the DGIV and trying it out. as you can see on the picture the blue screen with data is very unclear... I can barely see the text written... anyone have any idea?
Try scrolling the panel using the arrow keys, without using the shift key. Left and Right arrow keys move the panel left and right, because to me it sounds like you're using a small screen resolution.
Do you want to be able to read the DGIV's mini-HUD? If yes, then set panel scale to 1! You're breaking an intentional design feature by not having panel scale set to 1!
