HermitGuy - The 17" isnt only cheaper, but might be better depending on what your using it for. Since both the 19" and 17" are SXGA (1200x res), the 17" will have smaller Pixelpitch, giving it a sharper clearer image.
.... games will look clearer on the 17"... but text would apear slightly larger and easyer ot see probably on the 19".
---------------------------------
emjem - for some reason i doubt very much that its the monitor making the text change color when you scroll... try it on a different comp. and i dont know what Vidcard your using, but check your Collor Correction settings in advanced display options... also if your using 16bit Desktop color depth, that will show color imperfections on LCD's, switch to 32bit Color depth in Display settings, if that applys to you.
