Last time I did such research for myself, I chose a Benq RL2460H, which I am still very happy with. It is/was very popular with gamers, used for gaming conventions, etc, and has both a good picture and a very high performance for gaming (very little lag, etc). It also has a very nice clear picture and good colors. It cost about that much IIRC back then, but in the US market, which is cheaper than the European market, so I imagine now you might be able to find them there for about your budget. Doing a quick search, I find a Benq GL2460HM for £137.67 which seems to be very similar . At least it’s a starting point for comparison.
