The simple answer is that if you're on a tight budget and want a large screen Ultra HD TV that also supports HDR to some degree, then the M5500 is certainly worth considering. We're fairly sure you won't find a better 65-inch 4K model for the price and for that you get a well built TV with a great set of features. There are enough connections for most purposes, an effective remote control and a Smart TV platform that, whilst simple, includes most of the apps that you'll need. The platform is slick and responsive and the 31ms input lag means that gamers won't be disappointed either.
The greyscale and colour accuracy was excellent, especially after calibration and the video processing was also very good. The black levels and contrast ratios were impressive for an LCD TV, the motion handling was reasonable and the viewing angles weren't too restrictive. So what's the catch? Well the backlight uniformity was poor and unfortunately this affected the otherwise excellent contrast ratios. The HDR performance was also vey limited, with little of the wide colour gamut or specular highlights of which the format is capable.
The HDR support is a nice thing to have at the price point but the reality is that you won't find any TV at less than £1,000 that can really deliver a full HDR experience, let alone one that has a 65-inch screen size. Besides, the M5500's capabilities with standard dynamic range content are far more important because that's primarily what you will be watching for the next few years. In that sense the Hisense delivered an impressive performance and it's only the patchy backlight that lets it down. If the backlight uniformity had been better the Hisense H65M5500 would have been an easy Best Buy but it's a solid Recommended instead.
What are my alternatives?
At this price point we're not really sure there are many alternatives, in fact we don't think there are any. You will struggle to find a 65-inch screen size that has all the features found on the M5500 for anything like the same price and in reality you'll be looking at models over the £1,000 price point before you begin to get close. There's no doubt that Hisense have certainly delivered a very solid TV at an exceptional price in the form of the H65M5500 and we are now very excited to see how the higher end M7000 performs.
