Alienware AW3423DW monitor review. QD OLED makes it the best gaming monitor in the world

Posted by

Straight and without waiting: Alienware AW3423DW is currently the best gaming monitor there is. It erases all and much more expensive competition and defeats not only expensive LCDs, but also current OLED monitors.

The main attraction of the monitor is a new type of panel – QD OLED. It was developed by Samsung Displays and can currently be found on Samsung and Sony TVs as well as the Alienware monitor. We expect that Samsung will come with a similar monitor in time (at the earliest in the second half of the year), but so far the market leadership belongs to Dell and its brand Alienware.

Thanks to QD OLED, the image does not change even when viewed sharply from the sides. The design is in Alienware style

What exactly is QD OLED?

We have already written about QD OLED technology at AVmania, because it is mainly panels for televisions. The name consists of two technologies Quantum Dot and OLED. Quantum dots represent spheres with precisely defined dimensions per atom, which emit a shifted wavelength of incident light and thus change its color. The shift and thus the color change corresponds exactly to the size of the quantum dots. On the one hand, you shine blue on them, and on the other hand, green lights start to shine on them.

OLED it can only illuminate a single color pixel at full brightness, leaving the completely black pixel next to the off. As a result, OLEDs can provide absolute contrast with perfect black. Therefore, even in darker shades on the OLED, you get richly drawn colors, while the LCD colors fade due to the penetrating backlight, which gets a bit through closed “black” pixels.

In OLED for TVs are now the most common so-called. WRGB panels. They use white OLED (W-OLED), preceded by filters for red, green and blue subpixel. This W in the name then indicates one uncovered and so white subpixel, which will take care of a more intense brightness.

Because white light always consists of individual partial color shades, white OLEDs have to deal with the appropriate processing of the available spectrum. Traditionally, blue has the highest intensity and the best border in the spectrum. Red and green are more interconnected and thus harder to tune individually.

QD OLED is so smart. Instead of a white OLED, it uses a blue OLED with a precise border across the entire area. Green and red will then be taken care of by quantum dots, which will shift the original blue into better separated red and green shades.

They don’t have to help with complementary white because they don’t filter the color (removing unwanted colors reduces the brightness), but just changes the color without changing the intensity. As a result, QD OLED can fully illuminate green or red, and the brightest colors may not be white as with WRGB OLEDs.
