BUYING GUIDE<br />
referred to as ‘wide viewing angle’ technology. (Many<br />
assume this to spec to be IPS, but it’s not). In our<br />
experience, we’ve found VA panels to run the gamut<br />
from being worthy competitors to IPS to being worse<br />
than the better TN panels. The Gigabyte Aero 15 that<br />
we recommend above has a good VA panel.<br />
Generally, if colour accuracy is important, go IPS<br />
(a trademark of Sharp), and if you want the fastest<br />
response times go for a gaming-oriented TN panel.<br />
With the variability of VA, we recommend you check<br />
feedback from reviewers and users.<br />
The wildcard in all this are OLED-based panels.<br />
OLED panels have been used in phones for years but<br />
have recently migrated to larger screens in laptops.<br />
IPS, TN, and VA all use LEDs behind the screen or<br />
along the edges. ‘Black’ is produced by a shutter-like<br />
mechanism that blocks light from coming through. As<br />
you can imagine, there’s usually some light leakage,<br />
which means the black tends to be grey. OLED panels,<br />
however, don’t rely on edge- or backlighting and<br />
instead each pixel generates its own light. To produce<br />
black, it just switches the light off. This amounts to truly<br />
stunning contrast ratios and vibrant colours. OLEDs<br />
also boast fantastic response times too. The negatives<br />
include smaller screen sizes (we haven’t seen anything<br />
larger than 13 inches yet), higher cost, and lack of<br />
support for variable refresh rate.<br />
G-Sync and FreeSync<br />
Okay, we called this section G-Sync and FreeSync, but<br />
the reality is, when it comes to beefy gaming laptops,<br />
it’s a GeForce GPU world. And that means it’s a G-Sync<br />
