Haier M90E is an ambitious attempt by the manufacturer to enter the higher segment of the market. "On paper," the specifications look impressive: Mini LED backlighting, a VA panel, and a refresh rate of 144 Hz suggest a complete piece of equipment. However, reality verifies these assumptions. We get a device with two faces: a powerful hardware base that struggles under the weight of unrefined software. On one hand, we have excellent brightness, high contrast, and deep blacks, which combined with low input lag and HDMI 2.1 ports should make this television a hit. On the other hand, daily use is marred by annoying bugs: a poor dimming algorithm and an unstable Google TV system. It is clear that the manufacturer lacks experience in optimizing such a complex device. Who is this model for? Mainly for conscious users who can overlook system errors in exchange for high brightness. However, for the average consumer, the Haier M90E currently poses too great a risk. In this price range, the competition is enormous. We can easily find proven models from other brands that offer similar picture parameters but provide a significantly more stable and predictable operation. Rather than experiment, it would be safer to reach for solutions that do not suffer from "growing pains."
