Went for the P2450H on offer at OcUK in the end.
My first impressions (copied from another thread):
I got my P2450H yesterday. I'm planning to write a more detailed review, not long, but also with pictures when I'm ready. I'll give my first impressions though:
Pros:
Great looking monitor. Very nice.
Good size, ideal with Aero Snap.
Contrast is good, better than my old monitor for sure.
Quite good amount of customisation available on the OSD.
Scaling of non-native resolutions to full panel size is much, much better than my old Samsung 226BW. Shame I won't be using that feature.
Response initially looks great, no trails or artifacts observed yet. Conversely, my old monitor at 2ms used overdrive and produced white trails. This appears to be much more a true 2ms panel rather than an overdriven 5ms. That or the overdrive is miles and miles better. Samsung call this 'overdrive' RTA (Response Time acceleration) I believe.
Cons:
Stand is rubbish. No weight to it and as such the thing wobbles everywhere. Will probably need a desk mount.
Touch buttons take a little getting used to, not a major issue but may annoy some.
Settings out of the box are pretty far off perfect. Brightness wayyy too high like most new monitors really. Seems to have a slight dominance in green, though my old one was the same with blue before some tweaking. I think this one will need more thorough calibration.
Vertical viewing angle is quite poor. This is probably eccentuated because of the size of the panel (at the same distance from my face as the 22"). However, this is expected with any TN panel. I think a more adjustable stand will help alleviate this for me somewhat.
Overall, not the large jump in IQ I was expecting from my last panel. I think rather than a bad thing about the P2450H, this is more of really high praise for the 226BW. It was leaps and leaps ahead the Hanns G I had before that. The P2450H is a good picture with potential to be absolutely cracking once it's set up right. The only big let down is the stand, but it doesn't offer less than most in this price range anyway.
Very pleased with my purchase, the extra real estate will come in handy. Without seeing in the flesh the competition, IQ is hard to place within all new monitors.
