from my personal experience, i was totally flabbergasted by the way Matrox handled my case. again, i'd like to emphasize i'm simply informing you of my experience with this company and, of course, cannot speak for others' experiences. they decided to no longer renew their contract with the provider of their color adjustment software and, as a consequence, there was NO way for me to adjust colors via the Matrox menus! tech support was not helpful, nor was the sales department. they simply said that color adjustment is not longer available and that i should go out and purchase my own color adjustment software! as you all know, color adjustment on LCD's are not available on the LCD itself, and it requires the software of the video card to do so.
eventually, i even spoke to the senior people of the company. to my surprise, he didn't really know, but his first response was whether the sales literature/webpage specifically stated that color adjustment was available, and that should the material not say so, he simply said that he company did not break any laws!! my jaw dropped. who's talking about breaking laws? i was simply sadly surprised that the Matrox card was one of the ONLY cards i've ever heard of that doesn't provide color adjustment! you try ANY Nvidia, any ATI, basically any card that we talk about here on this forum, and see if you can adjust colors, and the answer is, of course!!
needless to say, i was not about to do any business with a sompany who's senior management's attitude was such. as they say, all these attitudes and way of doing business trickles down. of course, what do they care that they offended one person! but i was beyond insulted by all their staff and especially, the senior person who said that they didn't break any laws! no wonder their company essentially disappeared from the video card scene more and more, but kudos to them, they found their lil niche in unsophisticated, corporate/airport multiscreen market with low tech requirements. good for them. i'm personally staying away. again, this is one person's experience. i'm not speaking for anyone else. good luck!
