The Haier Q80FUX television is one of the most schizophrenic propositions we have had in our editorial office for a long time. On one hand, we have a solid piece of equipment: a VA panel guaranteeing deep blacks, as expected for this segment, and a QLED quantum filter that can indeed generate juicy, eye-catching colours. This is the foundation on which a truly competitive mid-range receiver could have been built. Unfortunately, all this potential of the matrix is systematically undermined by the software, which is a real anchor for this model. The biggest Achilles' heel of the Q80FUX is its total capitulation in dealing with HDR10 materials. The electronics seem to completely misunderstand how to interpret the signal, resulting in it consistently blowing out the brightest parts of the image, turning them into a flat, milky spot. Adding to this is the Google TV system, which – while functional – is unstable, full of bugs and annoying oversights, giving us an image of a raw product that clearly reveals the producer's lack of experience. Just when we were about to write this model off, we discovered its surprising niche. After connecting a console, the Q80FUX undergoes a transformation. It turns out that this television offers remarkably low input lag, fully supports VRR, and can handle a 120Hz signal in Full HD resolution. In the gaming world, where responsiveness is everything, these parameters put it in a very good light. So we are dealing with a device of very narrow specialization. It is not a universal living room television – it lacks stability and, above all, any correctness in handling films. It is rather a budget, large-format monitor for gamers, who can consciously forgive it all the software flaws in exchange for those few key attributes for console/PC at a relatively affordable price.
