Hi

Sounds like you may have a break in the cable that connects the graphics card to the screen. Every time you twist it, whilst it displays the screen properly for a while, it will potentially be making the problem worse. Unless you are confident and experienced at laptop repairs then this will more than likely need to be taken to a laptop repair person.

hello ratters

as hengis quite rightly said it could be the cable , and i have seen it many times before when the same problem could be the screen gone too ,
if you gently squeeze the lid around the outside edge does it have the same effect as twisting it ? either along the top edge or down either side?
if the gentle steady presure exerted around the edge causes the same good/bad screen quality then it would more likely be the screen,

this is fixable, with a little caution and patience ,but it may involve purchasing a replacement screen , if you feel comfortable in taking it apart,?

Hello Ratters, did any of the suggestions here help?

An update wouldbe appreciated
