Alienware support to try to wrap my head around the good, bad and ugly of kitting out your laptop with a 4K OLED
screen -- yes, there is some ugly -- I spent some quality time with three OLED-equipped laptops, the Alienware Support m15,
Razer Blade Advanced and HP Spectre x360 15. As an upgrade when you're
contemplating buying a laptop, it can be a tricky decision. Those
brighter-than-bright colors and deep blacks are alluring, and if you just care
about lots of colors and contrast, it's a no-brainer if you can afford it.Generally, it will add $150-$300 to the price, depending upon what the step-down option is. The Razer Blade, for example only offers the OLED touchscreen for its 4K option, for $300, and the configuration beneath it has a 1080p 240Hz display. The HP Spectre x360 15, however, can be configured with a run-of-the-mill 4K touchscreen. For that, the OLED step-up is only $150.
It's a low enough amount that it inspires serious
consideration, but high enough that it's not a no-brainer. And 15-inch OLED
models are a lot more common now than they were when 13-inches like the
Alienware Support 13 R3 debuted in 2016.
Why OLED screens are great
Alienware Support Since OLED produces primary colors by running electricity
through organic compounds rather than layers of various materials, the colors
have tighter spectral responses. The Alienware Support primaries can hit higher saturations,
which means they can more easily produce a lot more colors. Fewer layers --
because of the lack of a backlight -- means thinner screens too.

And because an OLED pixel can be completely off, it can
produce effectively perfect blacks and a glowing pixel next to a black one
bleeds less light, which would make the black look lighter. That means you get a higher contrast. Alienware Support With a backlight, at best you can turn off zones of LEDs to
get better blacks and control light bleed -- a technology called local dimming
-- and it's never quite as contrasty.
Alienware Support varying the backlight also increases the time it takes to
change a pixel's brightness, and the bigger the difference between the brightness of side-by-side pixels, the longer it takes. That lag, called
"response time" is important for gaming, where pixel states need to
change as fast as possible to prevent blurring where you don't want it.
OLED's response time is as close to instantaneous as you can
get with current technologies, though it's still subject to moving pictures
response time blur. To get even closer with an LCD you have to use TN (twisted
nematic), which otherwise is a real drop in quality over other options, such as
the more common IPS (in-plane switching).
But Alienware Laptop Support faces some significant drawbacks that a TV or
phone doesn't. Such as:
Since it can individually control pixel brightness values,
OLED is more power efficient overall than LCD for mixed content. But for a
mostly white screen, like when you're shopping on white-background Amazon or
working in white-background background Google docs, firing up all those OLEDpixels to a comparable brightness takes a lot more power. It does make them
easier on the eyes, though, despite the battery life hit.
TVs and phones don't have to run Windows, either. Their
displays are tightly integrated with the software and the best ones are factory
calibrated with selectable color profiles. Microsoft doesn't require custom
color profiles for monitors, and most end up with the Generic PnP profile,
which makes assumptions that don't necessarily apply to OLED. So no matter how
accurate the screen is -- an OLED can be very, very accurate -- if a video
says to the graphics subsystem "give me a saturated red," the default
profile shouts back, "You want red Alienware Support? I'LL SHOW YOU RED!!!" It doesn't
know how to optimally map the broader range of colors properly or how to not
crush all the detail in the dark shadows.
While OLED has a fast response time, the screens only come
in 4K, so you run into the fixed 60Hz refresh-rate limit. Depending upon the
games you play, ugly frame-rate sync artifacts like tearing and stutter may
overshadow the OLED's pleasing pop and fast pixel response times. The RTX2080-based systems are fast, but not fast enough for consistent 60fps 4K
gameplay, and if you drop to a lower resolution for better frame rates, you'll
need to use software-based vsync or cap the frame rate to get the best results.
The HP and the Razer both fully support Windows HDR -- by
"fully," I mean they send the "yes" flag to the OS for
supporting streaming video, gaming, and wide color gamut -- while the Alienware
only does streaming.
