I am having some problems getting the Pi running at a 1080p res on my new TV (HDMI of course).
First of all whenever I edit the config.txt file through my kali laptop, the next time I open it in my laptop (after the memory card has been inserted and the Pi has booted once), the config.txt file becomes entirely blank. I just have these four lines in my config.txt file-
I got the last two values by running the tvservice command. Anyways, with ONLY these lines in my config.txt I can boot up to 1080p resolution but my taskbar and windows have a strange bluish flicker.
Currently I am using my Pi with ONLY the config_hdmi_boost=7 line, which is booting up to 1360*786 perfectly fine.
