Display GUI with pixel

[arashadsaifi]

Hi All,

I have 5.7(inch) LCD with 320x240 pixel resolution. For my current LCD size and resolution I have developed some screens in Qt by using 320x240 pixel so it is completely visible
on LCD.

Now I am going to change the LCD size and resolution to 5(inch) with 800x480 pixel, but right now I don't have that LCD.

So I am planing to use current LCD( 5.7 inch with 320x240 pixel) for the 800x480 pixel but these pixels are not visible in the current LCD.

Is there any way in qt ( appart from writing own screen driver ) to solve the above problem either using LCD or VNC.


Thanks in advance.

How do you want to display the pixels that do not fit onto the display?
Do you want to...

1) Scale the image of 800x480 down to fit on your smaller screen until you get the larger screen
2) Scale the smaller image up so it occupies the whole area of the larger screen
3) Develop on the desktop and have some kind of emulator for the larger screen until it arrives?
4) Something else?

I want to down scale the screens 800x480 to 320x240, means your first option

If you are implementing your GUI using a QGraphicsView, you can just scale the view.
