That's your problenm right there. 640x480 resolutions have square pixels. It stands to reason that 640x350 resolutions then could not have square pixels.
350 / 480 = .7291666 Your square should be rendered as a box where its width is equal to its width and its height is equal to its width * .7291666.

Magmai, 320x240 is square too (it''s linear with 640x480).
Anyway, if the problem is that pixels on the sides of the screen are longer, it is due to the Pincushion and Trapezoid controls of the monitor. These can strech the image at the sides.
I think there can not be any other posibility. The aspect ratio could be also a problem but it would never make some pixels longer than others.
In my opinion, bother only about the aspect ratio, and let the people touch their monitor controls if they think they have to.
OK, my brain hurts whenever I think about this stuff, but... Most screen resolutions are 4:3, but most monitors are 4:3 as well, so...shouldn''t there be no problem here?
how big is your board? Is each square like 10x10 or 1x1? If it is a small number rounding errors would make a difference. Also while you are compensating for aspect ratio maybe that is causing a rounding error. If you haven''t already try it on a normal 4 to 3 ration. I mean you are compensating for it, but sometimes there is some other error elsewhere and everything messes up. Sometimes after exausting all logical solutions you try random things, and then you find that your error was somewhere else entirely, though hidden by a bunch of things that hide it most of the time.
are also 4:3 ratio, and can be adjusted to full the moniter screen using the moniter controls.
other resolutions such as 320x200 require the moniter controls to be adjusted so it displays properly (ie with the black borders). if this is not done, the image will be distorted. the alternative would be do do the aspect ration fix with the software. this is ill advised since ppl with their moniters set correctly will end up with a distorted image.
this is why some suggest only 4:3 resolutions. those that allow the other resolutions as well, odnt compensate for the different aspect ratio because it is (rightfully) assumed that the user (or manufacturer) set the moniter to show the correct aspect ratio so things appear as they should.
again, NO fiddling is required for an 4:3 resolution (the ones i listed above). doing so, will screw things over. if you do decide to do fiddling, remeber 4:3 is the target aspect ratio, not 1:1.
if the moniter and card are working (and setup) properly, any non 4:3 aspect ratio will be letterboxed, just like when movies are released in the 4:3 format and then letterboxed since the original was 16:9.
