I'm running 2 AG Neovo CW-19 Black 19" 4ms Widescreen LCD Monitors for online stock trading and am thinking of adding 2 more monitors for all the charts I display.
If I buy 2 more monitors, how important, if at all, is it that they match the first 2 monitors in specs such as response time, contrast ratio, pixel size, etc.? If I buy different brands or sizes, will it matter much if any? Would there be a compatibility problem? What should I look out for?
My video card, PNY Quadro NVS 440 will run 4 monitors from one PCIEX-16 slot with no problem.
Does anyone think that regular 19" monitors are sharper in resolution than widescreen monitors?
I'm not using these monitors for graphics work or gaming, just fairly simple 2D stock and currancy charts.
So if one monitor has a 5ms response time and the other a 4ms response time, it won't make that big a difference to the cpu or gpu? What about pixel size or different contrast ratios?
Disparity in response time isn't going to make any difference... that's something that's purely intrinsic to the display. You could have an LCD with a response time of 20 minutes and your video card would treat it the same as one with a response time of 2 milliseconds. The 20-minute one would be completely useless for independant reasons, but the video card isn't going to give a crap.
Native resolution DOES matter for some cards and purposes. If you want to extend one desktop space across two displays, it's best to get two displays with the same res... otherwise, your card might not care for it.
Make sure you can hook up the cables... If your card has two DVI ports, and two VGA ports, obviously it's not going to fly if you try to hook up four DVI or four VGA (without an adapter... which would be large and clunky and probably not work for geometric reasons.)
Since you're not trying to tile a game or video across several displays, the only other concern should be aesthetic preference. If it will make you unhappy to have 2 19 inch monitors and 2 17 inch monitors, or two black monitors and one white one, or monitors with different pixel spacing... you need to buy with that in mind.
