Obviously we can't tell you what you should or shouldn't do because this is personal preference.
But I would ask how you are getting on with it.
I didn't know what "Contrast Ratio" was, so I looked it up and found this;
"Contrast ratio is the difference between the darkest black and the whitest white that the monitor can reproduce. I highly recommend googling, since lots of people already investigated on this. The market converted it into a "marketing hook", so people think that "more contrast is better". I recommend between 1000:1 and 3000:1, but that depends a lot in the environment where you're gonna put your computer. The darkest the place, the more dynamic range the human eye has. So in those conditions the eye would be capable of differencing between 15000:1 and 20000:1, maybe more."
That was from here; http://www.tomshardware.co.uk/forum/54705-29-what-monitor-contrast-ratio
If yours works for you, then perhaps it is OK?

I have a new monitor with only 10000:1 contrast ratio, but I see there are many avaialable at 5,6,7 times that ratio that are only a few dollars more. I use it mainly for work with Outlook, Excel, Word, etc. Should I return it and get the better contrast ratio?. Maybe monitors will get even better in the next few year, and I should wait and be happy with the smokin deal I got...?
