I tried searching and all that... now it could be because im either an idiot or im just using the wrong keywords... but i cant find the right lcd screen size for a double din opening... i have a 1996 Mitsubishi Eclipse and it has a double din for the headunit... attached is a picture of an eclipse dash (not mines)

as you can see the opening is tilted inwards which makes it good for viewing the lcd screen... but im getting off topic...

Ok well this is the measurements ive taken from my radio bezel (if thats what its called)... W=7.5in H=4.5in and from oposite corner to oposite corner it measures 8.5in... so my question is... what size screen is that... would it be an 8.5in lcd screen... the openeing looks like its kinda wide... so a lcd screen wit an aspect ratio of like 4:3 wouldnt fit... so would it be a widescreen monitor... as u can tell im lost when it comes to this lcd thing... that seemed to be the only thing i couldnt find...
thanx for your help in advance
