Brightness, Contrast, And White Point
The maximum brightness of the Panther 5D’s Samsung panel is 377.4 cd/m2. This is brighter than many notebook screens, but close to 10% dimmer than the panel’s 400 cd/m2 published spec. Measured contrast is excellent. In my experience, the screen exhibits bright colors and deep blacks, and my measurements back that up.
A white point of 6500 K is considered neutral and close to the color of midday sun. If a screen measures below 6500 K, it takes on a warmer appearance that leans towards reds and oranges. If a screen measures above 6500 K, it is said to have a cooler appearance that favors the color blue. Cooler color temperatures are common in a retail environment because they make screens stand out next to other displays.
The Samsung panel's white point shifts from 6500 K at 25% brightness to 6900 K at full brightness. This shift towards a cooler white point as the screen becomes brighter means that calibration curves need to be created for each brightness level for the most accurate colors.
Viewing Angles
The screen has excellent viewing angles for a TN-based panel. Tilt the screen far forward and the colors shift to blue, tilt it far back and colors shift towards red. Side viewing angles are excellent, allowing several people to look at the display without a debilitating loss of quality.
Uniformity

Luminance uniformity is excellent on the bottom and middle sections of the screen, and merely good up top (the corners measure 15% and 14% dimmer than the center of the screen). This effect is visible on large swaths of single colors, but typically not noticeable in normal use. And the discrepancy is consistent across brightness settings.
Of course, the uniformity of this specific panel may not represent all of Samsung's 120 Hz panels. This is but one sample, and we know that there's variance from one display to the next.
Color uniformity is again excellent in the center and lower sections, but not as much in the top corners. Once you get past a Delta E value of four, the differences are apparent. At full brightness, this panel's top corners report Delta E values of 4.4 and 5.0. The fact that the rest of the screen is so neutral may make those shifts stand out more.

Taking brightness down to 50% significantly improves the panel's uniformity. Most readings drop under one, while the top corners duck in under a Delta E of three.
Our main reservation here is that you'll want to game with the brightness cranked way up if you're using Nvidia's 3D Vision glasses, since they take a huge chunk out of perceived luminance.
Gamma

The Panther 5D's gamma measurement comes close to the reference 2.2 curve.

the main people i can see needing this bad boy is division commanders on a battlefield as well as NSA hackers and CIA spies and Drone operators
but what i really wanted to see was the effects of ocing the gtx 680Ms
Finally I can have high end desktop performance on the go.
Lets see, a SFF setup parts:
PC: 5 = SFF-PC, keyboard, mouse, monitor, 2 power cords.
5D: 7 = 5D Panther, Mouse, 2 power cords, 3 power bricks/converter.
In return, you get a much better keyboard... then when broken, its a $10~150 replacement...
Nice machine, but it is overbuilt for a laptop if you need external monitors to use its full graphics. Sure you can take it somewhere where you can hook it up to multiple monitors, but then it is no more portable than a desktop.
Anyways, nice review. It's fun to read about the stupidly high end laptops that most of us don't ever see or use in real life, just to know what's possible if you go for performance over form factor.
I understand that it's "PERFORMANCE AT THE COST OF EVERYTHING ELSE" but wow.
To put this into perspective for that $6600, you could buy a fully loaded Precision M3800 quad core i7, 3200x1800 IGZO screen, 16gb ram, 512gb SSD + 1tb HDD and a Quadro k1100m that weighs 4lbs for $2600 and still have $4k left over to build a MONSTER workstation/gaming desktop
Lets go nuts. A 4k UP2414Q Ultrasharp Monitor for $1400
Core i7 4770k $300
2 x Nvidia GTX 780ti $700 each
512gb SSD
4Tb HDD
and a full build would still come out to less than 4 grand.
I think that statement is perfectly applicable to the Panther 5D.
