Failure to launch….and screen issues

Last week my bargain basement desktop PC died…….it refused to boot except for 3 short beeps and one long. POST (power on self test ) beep code for a memory problem I believe…….after opening up and re-seating the RAM memory modules nothing changed the outcome.

Still beep beep beep beeeeeeeeeeeeeeep. Luckily the 90 day warranty was still active. I rang the help desk at Encore and got an immediate response. Next day the desktop was picked up by courier. 3 days later I got my Thinkcentre back with a new motherboard and 8mg of RAM instead of 4mg…….a great result. Impressed with Encore-PC ………as long as this desktop build lasts longer than 3 months 🙂

Next I recieved an unwanted tv from a family member which could also be used a new monitor for my desktop. Unfortunately the initial result was as follows

And what I really wanted was

After much searching on the internet I have concocted the following script file which gets the screen I want

#!/bin/bash
#
# set screen display

xrandr
xrandr --newmode "1920x1080" 173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode VGA-1 1920x1080
xrandr 
echo "note the list starts at zero"
xrandr -s 4
