By saving the tutorial I sent in back in January on this very topic. I have reposted the more related parts below for your convenience. The simplest way to test for the ratio of any given resolution is to compare it to the base ratios with a calculator. For example, a 4:3 resolution can be turned into a simple math problem by saying 4 divided by 3 equals ???. The answer is 1.333 (the 3's continue on forever as a repeating decimal, but I cannot produce the line over them in plain text. lol) So, if a 4:3 ratio comes to 1.333, it follows that any resolution that also comes to that result is, in fact, a 4:3 resolution. On the other hand, a 16:9 ratio comes to 1.777 (repeating) and a 16:10 ratio yields a 1.6. With these answers in hand, here are some possible resolutions and their ratios. Note: I also added a couple from my 16:9 ratio monitor. 800x600 (800 divided by 600 =) 1.333 which is a standard 4:3 ratio 1024x768 = 1.333 which is 4:3 1152x864 = 1.333 which is 4:3 1280x720 = 1.777 which is 16:9 widescreen 1280x768 = 1.666 which is 16:10 widescreen 1200x800 = 1.5 1280x960 = 1.333 which is 4:3 1280x1024 = 1.25 1360x768 = 1.771 which is VERY close to a 16:9 widescreen 1360x1024 = 1.328 which is VERY close to a 4:3 1400x1050 = 1.333 which is 4:3 1440x900 = 1.6 which is 16:10 widescreen 1600x900 = 1.777 which is 16:9 widescreen 1600x1200 = 1.333 which is 4:3 1680x1050 = 1.6 which is 16:10 widescreen The remaining 2 resolutions (1200 X 800 and 1280 X 1024) wouldn't look proper on ANY computer desktop monitor and are there for other viewing devices. Hopefully, this will help clear up most of the confusion surrounding ratios and resolutions. :O) Peace, Gman "The only dumb questions are the ones we fail to ask" ----- Original Message ----- From: "cristy" <poppy0206@xxxxxxx> To: <pctechtalk@xxxxxxxxxxxxx> Sent: Monday, July 28, 2008 1:46 PM Subject: -=PCTechTalk=- Re: Desktop Wallpaper > How would one know the ratio aspect of their monitor? > > thanks, > > Christine --------------------------------------------------------------- Please remember to trim your replies (including this sentence and everything below it) and adjust the subject line as necessary.
