Is 'grain' inherrent to the M1330's resolution?

I've been reading up on screen resolutions of late and would like to pose that question. From what I understand, WXGA, the native resolution of the M1330, isn't actually a legitimate resolution at all.

​

Could the 'grain' issue so often referenced to Dells laptop range actually be rooted in the WXGA resolution itself, through it's lack of an actual aspect ratio, and not in the panel displaying it?

'1280×720 provides perfectly square pixels at an aspect ratio of 16:9, while the additional pixels in 1280×768 and 1280×800 must be ignored to give the 16:9 (Widescreen) ratio without vertical stretching of the image.'

Please share your thoughts and insights on this. I'm genuinely interested in how a non-standard display resolution became accepted by mainstream manufacturers of both computer and television screens.

 

Computer screens are usually 16:10, not 16:9 as home theatre equipment is.

1280x800 is a legitimate 16:10 resolution.

 

But from that featured article, WXGA refers to several resolutions. I don't understand how they can all be 'the same'. Especially since they appear to traverse the space directly between 16:9 and 10.

 

I think you're honestly reading a little too much into it.

The forums have been inundated with "Grain" threads, and I'm sure it has many people seeing things that really aren't there......it's bringing out the worst fears in people about their computer purchases.

I've got an m1330 and my screen is MINT!

 

Reading that confused the hell out of me
