VGA connectors support all widescreen aspect ratios. If you think it lends itself to 4:3, that is only because you have been using 4:3 projectors and the EDID in the projector requests a 4:3 resolution, but in reality, this is not at all the case.

A 1280x800 projector will request a resolution of 1280x800 or of 1280x720, and almost any recent laptop will deliver exactly that resolution. Likewise, most decent laptops can deliver resolutions up to 1920x1080 and beyond, so the higher resolution widescreen solutions also work.

But, the native resolution of the projector is what will determine what is requested by the projector to be sent to it and the push, in the industry, is several years past 4:3 being the 'standard'.

As an example of this, of the 272 projectors which are between 5000-7000 lumens, 172 of them are 'widescreen' aspect ratio. A few years ago, that would have not just been flipped, it would have been about 30 or 40 widescreen models compared to a couple hundred plus 4:3 models. The shift to widescreen projection right now is drastic, and increasing.

Why? Because you can't BUY a 4:3 television anymore. Almost every laptop on the market is widescreen. All the PC monitors are also widescreen, with a great number of them being 1920x1080 resolution (1080p).

Projectors generally accept a 4:3 input such as 1024x768, and maintain the aspect ratio. They can also stretch it to fill the widescreen image. They all work within the height confines of their current projection size/distance.

As AV_Integrated said, VGA connections will not give you any trouble. What will give you trouble is a projector that only displays in a 4:3 resolution. As everything generally moves to wide screen, relying on this old standard puts you at risk for some odd stretching from new resolutions, while there is almost no risk of the same from a source putting out an (old) 4:3 resolution.
