Dell Alienware AW3423DW Review (QD-OLED 175Hz Ultrawide)

Rating: 9.0.

OLED panels have been common place in the TV market for years, but it is only recently we have started to see the technology make its way to the gaming monitor segment. The Dell Alienware AW3423DW offers a QD-OLED panel manufactured by Samsung, in a 34″ 3440×1440 form-factor, with a fast 175Hz refresh rate. Today we find out exactly what OLED is capable of for the enthusiast PC gamer.

On paper, OLED technology looks like a dream for gamers. Offering native, near-instant response times is a key part of this, as are the per-pixel dimming capabilities of OLED panels, which should surpass even full-array local dimming HDR solutions. Wide viewing angles are also promised, along with an effectively infinite contrast ratio.

At £1099, the Dell Alienware AW3423DW isn't cheap, but compared to some flagship LCD solutions that have hit the market in recent years – including as the ASUS ROG PG35VQ at £2700 – I don't think the pricing is outrageous considering the features on offer. Without further ado, let's dive in and find out if it is worth the cash.
