A look inside
The bottom of the P57W is secured with sixteen screws and a number of plastic tabs along the edges that "pop" it tightly into place.
The system supports up to 32GB of RAM, but it only has two RAM slots. Expect to pay about $130 to max out the P57W's memory capacity.
Here's the laptop's system drive tucked into its M.2 2280 slot. The LiteOn drive shown here uses the SATA interface, but the slot offers four lanes of PCIe 3.0 connectivity for NVMe SSDs, too.
Here's the empty drive bay in the middle of the laptop's front panel. Too bad it doesn't double as a slot for a second battery. Gigabyte's included adapter converts the SATA connectors for the optical drive to the standard connectors we want for SATA storage devices, so 2.5" SSDs or hard drives can slip right in.
To test the screen of the P57, we used an X-Rite i1 Display 2 colorimeter and the free-and-open-source DisplayCal. An initial profile of the display showed some problems. At roughly 7000K, the screen's white point was too cold, and the gamma was 1.97. Ideally, we should be seeing gamma closer to 2.2 with sRGB. Calibrating the screen with DisplayCal adjusted the white point down to our preferred 6500K—at least, in theory. Users without a colorimeter can use Gigabyte's provided Smart Manager tool to get a similar result.
Unfortunately, the graph above shows some problems that persisted after calibration. The display's white point still isn't quite where we want it, and the panel can technically produce more greens and reds than are contained in the sRGB gamut. DisplayCal reports that the screen covers 89.7% of the sRGB gamut, which isn't spectacular, but it should be acceptable for a mainstream or gaming audience. Professionals looking for higher gamut coverage probably want a higher resolution than this screen provides, anyway.
By another measure, the screen proves to be remarkably accurate. The screen's average delta-E is only 0.18. We're happy with any result less than three.
We also want to be sure of peak brightness and luminance uniformity when we test laptop screens. The P57W turns in a 330.36 cd/m² maximum brightness at its center, an excellent result. The screen's luminance is also quite uniform, deviating from the brightness levels in the center by an average of just 3.4%.
As you'd hope with an IPS panel, the display provides excellent viewing angles. On a more subjective note, I'll add that this screen is quite bright. I never found the need to have the brightness turned up all the way, especially indoors.
