jap - there may be exceptions - but generally, laptop screens are useless without the/a laptop mainboard.
cap - i'll take some pics so you can gauge dimensions if you like. Unless it is the price putting you off? The 8" is likely the same ish width as 7" widescreen, just a little taller. Let me know if you want exact dimentions. Its a great screen, I am only looking to sell because I have 3 weeks before my next student loan & I am slightly short of cash at this moment, due to a run of bad luck.
