Re: Custom resolution for 1280x320 LCD

It does output picture if I set the resolution at 1280x640 for example but it shrinks it. Hence why I asked if it's possible to make it spill out? Anything we can do in the config.txt file to achieve this?

Thank you.

My questions:

Is QT Quick the right tool to do this with? I'd like to program using QML.

Or do I need QT creator or something?

Thanks for all the Help.

Re: Qt on Raspberry Pi as an Embedded System

By doing so will the boot time reach 2 seconds or less till it runs my application?

How do I specify where my application is and also will the built project with QT just run as soon as it's called?
