Well calibrating your monitor will possibly make the monitor appear washed out also. If that is your objective then great, but I suspect it is not.
Sorry, but that's bad advice. The point of calibrating
and profiling your monitor, is to turn it into a dependable visual reference. If you've done that correctly, and your images still look washed out on the monitor, then that will be because the images
are washed out, rather than your monitor making them look that way. So you can then confidently adjust you images to look good on your monitor, and have some hope that others will see your images the same way you now do, and that if you have them printed (via a profiled printing workflow) that the prints will look OK too.
There are indicators on the screen such as the histogram that can be fixed with levels and other controls that will possibly have a far greater impact for less money.
Oh yes, you can make it look OK on your display that way, but it will look terrible on anyone else's display, uness it just happens to be misadjusted in the same way as yours. And then when you print it, it will look different again.
i.e. the whole point of color management, is to cure this type of situation.
BTW, I had a Spyder 3. They stopped supporting the software so I had to get a Spyder 4. Now there is pretty much no support for that, but I won't be buying a Spyder 5 (or 6).
If you look, there is still support for Spyder 2 through Spyder 5. If you have a choice though, I'd recommend choosing an i1 Display Pro, although the Spyder 5 is noticeably better than it's forbears.
