I am new to raspberry pi however since my works as an IT tech is dead quiet due to stage 4 L/D I started playing with rasppi to kill time in-between family time. Now I have a question for everyone,
After I installed the display, I decided to tinkered with Appearance Settings as I normally use black background for all of my devices however what seems to be interesting is that upon tinkering with Picture as a background in DSI-1 tab, nothing changed as shown in the 7" display. But then, when I changed the background in HDMI tab, the change was reflected. Then I explored that DSI actually is, they are all referring back to this 7" display. My question is (outta curiousity): is this always the case?
The next question is: the touchscreen leaves a big gap between the location either my finger or my touchscreen pen and its arrow. Is there any way to fix this?
