I'm trying to use qtquick project on my raspberry pi. I have a jpeg image on my project. The problem is when I cross compiled the project to the raspberry the quality of the image is getting bad as on the picture below... ( Left hand side monitor is connected to the raspberry pi)

My Screens

How can I handle this problem ? From where I have to start ?

It seems that color depth for EGLFS on RPI had been set to 16-bits. You can explicitly change it by 

export QT_QPA_EGLFS_FORCE888=1

on your RPI console. You may also want to set it permanently by adding it to /etc/profile
