Hey guys!

I just shot my first project with the HPX170, the images are much smoother and cleaner compared to the HVX200, I even found them to be sharper, or are my eyes playing tricks on me?

I did however end up underexposing a few shots. Although it's probably the same LCD as in the HVX200, I found it to display images differently. For starters the EVF function is much more aggressive. Using the WFM resulted in properly exposed images, even though they looked overly overexposed on the LCD (calibrated LCD with color bars). When I relied solely on the LCD I ended up underexposing by a stop or so. The footage did handle color correction very well with little or no visible noise.
 
Yes, I was way off on a couple of images. Was shooting run and gun, so had very few opportunities to check the WFM. Here's the footage: http://vimeo.com/1986778 Held up pretty well in post, had to desaturate and compensate for the overexposure.

You're right: the monitor seems the same, but evidently there are some improvements (also in retroillumination, I think) so it look much more better. HMC150's monitor is even much better than HPX one: if you look at the two cameras side to side HMC monitor seems to have more resolution

Okay, first of all, never rely on the LCD to judge exposure. You simply cannot, because if you angle the LCD even five or 10 degrees off axis, it will drastically change how the image looks.

Use your zebras and the waveform monitor to set exposure - always!

Second of all, if you just aren't going to do that, and you insist on using the LCD by itself (which is totally the wrong way to do it), then at least make sure you're looking at the proper angle. On an NTSC unit you can do that by popping up the color bars, and looking for the small vertical gray stripe in the PLUGE section in the lower right corner. Adjust the angle of the LCD until you can just barely discern that stripe, and then you will have half a prayer of the LCD showing you proper exposure.

But again, that's the wrong way to do it. Use the zebras at all times, and occasionally pop up the WFM. Then you'll know exactly what your exposure is.

I'm completely aware of this and agree with you. I always use zebras. Usually Z1 set at 95% and Z2 at 105% when shooting landscapes or buildings, and Z1 set at 70% and Z2 at 95% when dealing with people and skin tones. However when dealing with scenes that exceed the camera's dynamic range and specially when shooting run and gun, there's so many stripes on screen and I find it to be distracting. After shooting for some time now with the HVX I am able to judge exposure using the LCD. The HPX's LCD seems to have a much narrower viewing angle, and even after "calibrating" the LCD in my opinion properly exposed images are rendered overly bright, probably the angle. On the HVX it wasn't that pronounced.
 
I have also noticed a difference between the LCD and the EVF.
The EVF seems warmer and darker than the LCD. The LCD looks much brighter.
I know we can now adjust the backlight on the LCD by 3 steps, which is the "proper" step?
