It's this part:

# Error test for Screen Dimensions
ErrorTest="$(xdpyinfo 2>&1 > /dev/null)"
if [[ $ErrorTest != "" ]];then
ErrorCondition=$(echo "$ErrorTest" | grep -c resolution)
if [[ $ErrorCondition == 0 ]];then
ErrorTest="Error"
fi
fi

Again, look at the following:

$ ErrorTest="$(xdpyinfo 2>&1 > /dev/null)"
$ echo \'$ErrorTest\'
''

Yet we see
$ xdpyinfo | wc -l
647
lines returned and a test for resolution shows
$ xdpyinfo | grep -c resolution
1

I suggest the if test just needs to check for resolution.

oK,

Sorry about that.

# Screen Dimensions
TestX=$(xdpyinfo 2> /dev/null | grep -c resolution)
if (( $TestX >= 1 )); then
ScreenDimensions
printf "%s\n" "Screen Dimensions"
FWLine
printf "%s\n" " Dimensions: $Dimensions"
printf "%s\n\n" " Resolution: $Resolution"
fi
