Conclusion: 1280x1024 is NOT a valid 4:3 aspect ratio and should NOT be used by anyone unless their monitor's aspect ratio is meant for it. But thanks for playing, there's a consolation prize behind door labelled "Brainwashed".
You sad sad sad little man, Ill tell ya something, my viewsonic monitor is kick ass, but you should already know that being the all mightly knowing one as you think you are,and as for it not holding to 4:3, well guess what it can hold 4:3 in 1280x1024, becuase (as you would already know, since you know all) the screen vertically spreads a little more in this mode, to hold the 4:3 ratio, as to WHY im brainwashed to use this res, well I dont much im normally in 1600, but if i couldnt reach that, i would use 1280x1024 becuase i get more lines on the screen that way. And honestly ratio of 4:3 or 5:4 being less than 7% change would mean jack all to me in what i do.
Now Ill ask you, Why buy why do you feel it was so important to be in 32bit mode? What you think you can see that fine a color spectrum?, Oh but why ask you would already know why, knowing all, .....hmmm wait a sec didnt you not know something to begin with? werent you asking a question?
oh PS, if i wanted to be as close minded as you I could have just cut your example to peaces
lets sart with 1.3 whcih was actually 1.33r but rounded so to be fair ill apply the rounding to all answers, now 1.25 should be rounded resulting in 1.3 which , well wow is the identical value so there all the same, so you dont get no prize today!
