Well I tried it out last night unfortunately only briefly (about 15 mins) and I've got mixed feelings really (this is all from a gamer's perspective)...
Pros:
- Absolutely no input lag; makes such a difference compared to my old Dell 2001FP and feels like a CRT again instead of feeling like being "on ice"
- Very sharp response time, no ghosting whatsoever. COD4 looked crystal clear when moving about rapidly
- Amazing image quality in games; most impressive
- Black depth I found was not too bad! I was able to discern the 2nd/3rd black square on the lagcom LCD tests
- Backlight uniformity didn't seem too bad, no major backlight leakage
Cons:
- Colours looked either washed and lacking vibrance in Windows (might be because of the 92% NTSC colour space "wide gamut" of this monitor)
- Screen seemed almost "too big" for use on a desktop...found myself thinking "hmmm, this seems ridiculously big!"
- Pixel pitch of the screen combined with it's large size and H-IPS setup made the screen look fairly grainy up close
- Discovered a complete bright pixel (stuck on red) about a 1/3 from the left hand edge of the screen about 1/5 of the screen from the bottom. There is also a bright sub-pixel on the mirroring side of the screen (1/3 from the right, same distance from bottom). Both aren't too invasive however...
- OSD is quite frustrating to use (as others have mentioned, once you highlight an entry and hit 'select' there is no indication of whether you now have 'control' of that item...especially annoying as the OSD is only touch sensitive without buttons)
It's strange, most of the issues I was worried about haven't been a problem; I never thought the colours would appear "washed out" at any point and I certainly didn't expect the screen to be showing such nice blacks and not be too over-bright as well!
Need to do much more tinkering tonight and make a decision whether to keep it or not. 26" does seem really excessive at the moment though - will have to get used to it!
