Reviews on Amazon suggest the Philips BDM4037UW isn't a good choice due to significant ghosting issues:

I have it on my desk right now and ghosting is really, really bad. Static contrast ratio is best in class, second only to oled monitors.
If you are looking for large office/work monitor only or you can borrow one with no strings attached, go for it. Otherwise stay away.
A huge boon for productivity having come from multiple 27" 1440p monitors before, and the BDM40 is something I might recommend for somebody looking to get in and get in cheap.
I'll definitely be splurging for something better next time however.
