In reply to 1101, yes you are right that if I had a computer and loaded linux on it and then the screen failed the warranty and CGA would both apply, but in this case Samsung have explicitly stated that loading "linux" on to this computer voids the warranty, and so the CGA is the only thing that applies.

 

I was lucky to have them replace the LCD under warranty considering the warranty being void, but if they hadn't done it under warranty I could have pressured them to do it under the CGA for free since the fault was unrelated to any software that I had changed.
