^ this is spot on imho.
The Philips monitor obviously has TV roots, you just need to look at the stand to see that. After now working with my monitor for a week I can honestly say that the size isn't too big for a desktop, BUT you need it at desk level otherwise it really is too high.
People keep mentioning "what's the catch?" with this.
I can tell you:
VA cone effect (minor problem and pales into insignificance vs backlight bleed in many other "premium" monitors).
Input lag and motion handling. Input lag is there but nothing I haven't experienced before. This isn't a gaming panel, but unless you're used to 120hz+ will you notice any motion issues? I DO notice it a little, but this is probably because I'm viewing a big screen up close. It's acceptable, although if I were pumping 000s of hours into something like BF4, COD or counterstrike I wouldn't buy this monitor.
There's also grey trails when you scroll text, mainly obvious with large fonts but you can see it if you look at smaller text too.
OSD. Pretty crappy.
But look, this is £650 for a 40" (!) 4k panel, and it scales to lower resolutions well so even if 4k gaming doesn't always work well with your GPUs (Crysis 3 I'm looking at you), you can still enjoy a good gaming experience.
Oh and did I mention the screen real estate?
