I am connecting to my astropi with my samsung galaxy tab e 9.6 via vnc and the resolution is set to 656x416 and i am trying to increase it to 1280x800 via the config.txt file at the sd card with no success. The lines i am editing are the following
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=xx (where xx i set the number form 27 to 31 since it is the resolution of my tablet)
Another thing i could try is the following line
hdmi_cvt=<width> <height> <framerate> <aspect> <margins> <interlace> <rb>
width width in pixels
height height in pixels
framerate framerate in Hz
aspect aspect ratio 1=4:3, 2=14:9, 3=16:9, 4=5:4, 5=16:10, 6=15:9
margins 0=margins disabled, 1=margins enabled
interlace 0=progressive, 1=interlaced
rb 0=normal, 1=reduced blanking
eg hdmi_cvt=1280 800 60 5 0 0 1
do i need to do anything else in the config file if i use the above line? Also from the specs of the screen i can't find the framerate of the screen
Screen specs
Type TFT capacitive touchscreen, 16M colors
Size 9.6 inches, 267.2 cm2 (~73.9% screen-to-body ratio)
Resolution 800 x 1280 pixels, 16:10 ratio (~157 ppi density)

any help is much appreciated.
