I picked up a Samsung 970p today and have a few comments.
The viewing angle is fantastic. Best I have ever seen in LCD, even looking up from below. There is a slight gamma shift as you move away from the normal. But text is still fully readable and colours remain the same, though a little paler, even at nearly 90 degrees (ie, completely side on).
Colours and sharpness is fantastic, as is to be expected with an LCD. The uniformity of the backlight is much better than I have seen in other LCDs. The wide viewing angle probably has a lot to do with this.
The 2x2 dithering is particularly noticeable when I sit within about 10 inches from the screen, but not distracting and when I sit more than 10 inches from the screen it's not noticeable. I don't mind it either way, although when editing raster graphics (ie editing graphics for the web with photoshop) it may be an issue, but can be worked around.
The response time is great. I'm not a heavy gamer. I rarely get into games but I have been playing a FPS style game recently. Many do not like the motion blur effect when panning but I think it looks awesome. Considering that the colours are so much better it is a pretty good deal.
The overdrive effect (response time compensation) is noticeable. As you pan, there is a white edge trailing the black tree trunks, and a black edge trailing white objects like laser beams etc. But it still looks pretty cool. As I said, some people don't like the motion blur but to me, it is pretty cool and not too heavy to be a distraction.
For video it is more than worthy, overkill in fact. The sharpness of LCD makes all the grain and MPEG noise in a video much more noticeable.
It has no dead pixels.
Installation was no problem although I think the supplied software is a bit crappy. The magic rotation application kept popping up errors after I disabled the tray icon. I've uninstalled it. I don't think I really need to rotate my desktop. The magic tune application is a bit clunky and I think it might have been crashing my computer - in combination with my graphics drivers. Anyway, it worked well enough to use it. I calibrated my monitor with it, and then uninstalled it. Set it the way you want then get rid of magictune.
I needed to adjust the gamma up a bit (ie, make mid tones darker) to match a 2.2 gamma. The black level is not configurable (from 100 to 50, the brightness adjustment alters the backlight intensity, and from 50 to 0 the backlight stays the same and it is like turning the contrast down). But I found the black level to be perfect. I found I needed to turn the contrast down a little tiny bit from the default to gain back some detail in the whites. The colour calibration tool was easy to use and impressive, as I haven't seen that in an LCD before.
Mine is black. It looks nice, and suits my black keyboard and mouse. I don't need the glossy good looks or flashy designs, I am mainly interested in graphics quality, but the simplicity of design is a plus.
Some have said that the hinge is a bit loose and the monitor will slowly slide down over time if you have it up high. Mine seems to hold the weight of the screen fine. Makes sense that not all hinges would be the same though.
Oops, I forgot to mention brightness. It's virtually impossible to tell how bright a monitor is with the human eye other than how it compares with surrounding light. This room doesn't get much sunlight so it looks extremely bright. I had to turn the backlight down. You're not likely to be disappointed, but then again I haven't tried it in direct sunlight.
Positives: colour, sharpness, contrast, viewing angle (for an LCD), response time (for an LCD with a viewing angle and contrast ratio like this)
Negatives: 6-bit+dithering (if you edit raster graphics), supplied software (but you can use it once then remove it)
