cogadh: That's not how true widescreen works. Actual widescreen support just adds the option for full screen resolutions that work on 4:3, 16:10 and 16:9 monitors. If you have games that do that differently, odds are you have your game configured wrong. Also, what world are you living in that doesn't have clear type and font scaling? Wide screen monitors, which are the standard, not the exception these days, are actually far easier to read than woefully outdated 4:3 monitors, if you bother to set them correctly (which all modern OSes do automatically now).es no sense whatsoever.
Widescreen is 16:10 or 16:9, 4:3 and 5:4 are not wide. A game has widescreen support if it fills the screen of the first two of those aspect ratios regardless of how it handles the latter two, or even 21:9 for that matter (that isn't "wide", it's "ultra wide"). Though I agree that games
should ideally support various screen aspect ratios, there are several today that actually don't support anything other than widescreen resolutions. Also 4:3 and 5:4 monitors not at all "outdated" as there isn't necessarily a technological advantage of a wider aspect ratio, but is mostly a matter or preference.
Yes, newer screens - especially ones with high pixel density such as the fairly recent advance to "4k" monitors - are likely easier to read on as pixels get harder and harder to notice as they get placed closer together and as panel technology advances for better colour reproduction and contrast - such as the step-up from TN to IPS - but neither of those have anything to do with a widescreen aspect ratio in and of itself.
Humans generally prefer not having too long lines of text while still seeing the rest of the text in the periphery, and using fullscreen on a widescreen monitor either makes lines too long for comfort for many (compare 1600x1200 to 1920x1200), or lowers the numbers of visible lines on the screen (1280x960 or 1280x1024 to 1280x720 or 1280x800) and thus not letting the reader see as much of the text around what they're focussing on as they could otherwise and brings more work in scrolling down and up to continue reading or refer to something earlier. Studies have shown that people generally find it more comfortable to read longer pieces of text on portrait-mode screens.
