BUYING GUIDE referred to

BUYING GUIDE referred to as ‘wide viewing angle’ technology. (Many assume this to spec to be IPS, but it’s not). In our experience, we’ve found VA panels to run the gamut from being worthy competitors to IPS to being worse than the better TN panels. The Gigabyte Aero 15 that we recommend above has a good VA panel. Generally, if colour accuracy is important, go IPS (a trademark of Sharp), and if you want the fastest response times go for a gaming-oriented TN panel. With the variability of VA, we recommend you check feedback from reviewers and users. The wildcard in all this are OLED-based panels. OLED panels have been used in phones for years but have recently migrated to larger screens in laptops. IPS, TN, and VA all use LEDs behind the screen or along the edges. ‘Black’ is produced by a shutter-like mechanism that blocks light from coming through. As you can imagine, there’s usually some light leakage, which means the black tends to be grey. OLED panels, however, don’t rely on edge- or backlighting and instead each pixel generates its own light. To produce black, it just switches the light off. This amounts to truly stunning contrast ratios and vibrant colours. OLEDs also boast fantastic response times too. The negatives include smaller screen sizes (we haven’t seen anything larger than 13 inches yet), higher cost, and lack of support for variable refresh rate. G-Sync and FreeSync Okay, we called this section G-Sync and FreeSync, but the reality is, when it comes to beefy gaming laptops, it’s a GeForce GPU world. And that means it’s a G-Sync 80 TECH ADVISOR • MAY 2018 Worldmags.net

BUYING GUIDE AMD’s FreeSync technology helps reduce screen tearing world. In a nutshell, Nvidia and AMD’s respective variable-refresh-rate technologies help synchronize the monitor and the GPU to greatly reduce screen tearing. Variable refresh rates can make gaming at 40fps far smoother to your eyes than a screen without it. The first variable-refresh-rate panels for laptops maxed out at 75Hz, which was only marginally better than the standard 60Hz. More recently, we’ve begun to see laptop panels that can push 120Hz. This means smoother and sharper gaming. It even helps smooth out everyday tasks such as scrolling a browser page or Word document. The downside of high-refresh rate panels is the technology it’s available on: TN. As we said earlier, TN generally looks less vibrant and less accurate than IPS. Off axis is generally inferior too. Which is right for you? If it’s primarily a gaming laptop – go for a high refresh Worldmags.net MAY 2018 • TECH ADVISOR 81
