What would be a good 1080p IPS display for gaming

I need to buy a new monitor and I've been considering 4 different monitors. First we have the [asus VN247H-P](http://www.newegg.com/Product/Product.aspx?Item=N82E16824236307) for £100
My second choice is the [Acer H236HLbid](http://www.newegg.com/Product/Product.aspx?Item=N82E16824009483) for £90
My last two choice are the dell ultrasharp monitors either the [U2412M](http://www.newegg.com/Product/Product.aspx?Item=N82E16824260047) or the [U2414H](http://www.newegg.com/Product/Product.aspx?Item=N82E16824260174)
.I've had a shitty monitor for years and I now want an upgrade I was very close to pulling the trigger on the ultrasharp U2412M until I realized the high input latency. So what would you guys buy if you were in my situation

The Dell U2312HM is a nice one with lower input lag
