So ages ago the back light on my laptop went but as I had a spare old monitor screen from when i used to own an xp desktop pc. so i decied to use the screen as my main monitor. So I could still use all the stuff on my laptop whilst i saved up for a new laptop. However since yesterday I the vga cable broke and know everything is tinted blue. So today I went and brought a new cable but my monitor only seems to work with the tinted blue one.  However my laptop still recognizes that the new one being plugged in as it changes the screen size on my laptop. yet the monitor just says no signal received. 


So is there anyway I can get the new one to work as I viewing everything in tinted blue is really annoying when i spend most of my time in photoshop.

You have three components here, any one of which could be causing the problem - the laptop; the cable; and the monitor. You may need the help of a friend who has a monitor that he will let you plug your computer into !


Plug your computer into a known good monitor using either, or, better still, both of your cables (one at a time !). If the imagery and anything else you want to try to display comes out OK on this monitor, then the problem is with your own monitor. If it comes out with the blue tint, then the problem is with your laptop.


As a final check, connect a different laptop to the monitor and see what the display looks like. If it comes out blue tinted, it's the monitor. If it looks normal, it is almost certainly a problem with your laptop.

If swapping back and forth consistently works (but blue) with the old cable but gives no signal with the new one, it would seem the new cable is not working correctly. You'd hope it wouldn't happen, but a new product can be faulty out of the box - if there's any way you can try it on another computer, that would prove it.
