stay away from it since it's not IPS ( idk what is IPS exactly
, but it's amazing for gaming )
both screens ( Dell & LG ) are IPS technology monitors , but i would go with the LG since it's :
1- Bigger
2-has 5ms response time ( dell has 7ms ) : lower response time means better
3-newer technology
Dell Monitor :
1-cheaper
buddy , check the prices in the market , if you found the LG is more than 1500 expensive than the dell monitor , go with that dell , it's perfect too .
and yah , this is another one : i think it's cheaper than both :

and better than both !! , look for it , if you found it , get it . Good luck .
