The JVC fared a little better than expected in our testing. In SDR mode, its default Standard picture preset puts out a maximum brightness of around 369cd/m² and achieves a very respectable contrast ratio of 5,329:1 even with all the contrast– and colour-enhancing features turned off. Fire up HDR mode, and peak brightness increases to 400cd/m² while contrast remains high at 5,358:1.
It’s a shame, then, that Dolby Vision content in the Disney+ app suffered from some horrible juddering during our testing. Netflix was seemingly unaffected but watching content via Disney’s streaming service was blighted with hitches and jerks throughout. Once you notice it, it’s very distracting. Hopefully this is something which can be ironed out with a future software update.

At this price, those talents are routinely in short supply. JVC Fire TV Edition review: Key specifications The TV comes in three sizes – 40in, 49in and 55in – and all three have support for the HLG, HDR10 and Dolby Vision formats. That means you should be able to enjoy streaming HDR content from any of the main providers, with the added bonus that you’ll get the best results on any streaming service with Dolby Vision support, which currently includes Disney+ and Netflix. Once you’re into the Fire TV interface proper, you’re faced with a familiar set of tiles offering apps, recently watched programmes and suggestions of things you might want to watch. In addition to the usual suspects, you’ll also notice tiles for the TV’s various HDMI inputs and terrestrial TV tuner. These inputs are treated just like apps or watched programmes, so if you regularly use the HDMI 4 port, for instance, then that gets pole position in your recently watched list. Those colours aren’t as intense as they should be in HDR mode, though, so don’t expect the kind of eye-popping colour which you get from pricier sets – the JVC covers a mere 70% of the DCI-P3 colour gamut, which is far less than even many mid-range TVs. By the same metric, even LG’s affordable UM7400 managed to cover 82% of DCI-P3. As the JVC employs a VA-type LCD panel, it has a familiar set of pros and cons. Viewed head-on, it supplies a surprisingly vivid, high-contrast image. Move even slightly away from head-on, however, and the contrast and colours fade away rapidly; the viewing angles are narrow at best. As a result, wall-mounting it above eye-level is a no-no, and you’ll want to be seated directly in front wherever possible, which may be awkward in many living rooms.
The biggest issues with the JVC, however, are that it struggles with both motion and upscaling – two key performance elements of any self-respecting 4K TV. I didn’t expect much given the 60Hz refresh rate, but the panel’s slow response time is painfully obvious. It’s not too noticeable in brighter scenes, but detail and colours are smudged by horrible blur in darker moments. Similarly, while images look crisp in 4K when the camera is moving slowly, fast action and sports shows up the panel’s limitations, with detail becoming flattened and indistinct.
