Help choosing a 2 purpose screen

[tanin]

Hello,

I'm looking to buy a playfield screen for "waiting for time and money minicab".

This screen will be used for a playfield till I build a 2 screens full cab(in a year+), where it will be used for backglass+dmd.

I was thinking about this Dell(P2414H) screen:

Is it a good choice?

p.s. I may be tempted by this Lg 27"(what do you think):

I'd buy the cheapest one you can find because in a year, 29" tvs will be even cheaper. I saw a 32" at target the other day for $180 USD. The 24" monitor is nice, but way too small for a BG by today's standards.
