I have spoken to curry's who have been no help at all and asked have i been mis sold the tv or is the tv due an update to activate the HDMI 2.1. You'll sometimes see specific processor details on high-end sets from other manufacturers, but rarely on cheap TVs unless it's something generic like 'Quad Core' etc. I've never seen RAM specs mentioned on any TV I've ever looked at and I'm not sure what you mean by disk ?

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. To be honest though - if you're concerned about things like processor speed and RAM, then you should really be avoiding JVC altogether. JVC TVs are made by Vestel and pretty-much exclusively for Currys. Spending a decent amount of money on a Vestel TV with only a 1 year warranty may not end up being a good move. LG, Samsung, Philips (etc) all make 65" TVs in a similar price range that will most likely be a better bet than JVC, plus will usually come with a 5 or 6 year warranty if you buy them elsewhere. One place the JVC does trip up is in its latency. Even in its built-in Game mode, the TV displays a lag of 42ms. The result was even worse than the 33.8ms achieved by the Hisense A7100, which doesn’t have a game mode at all.

It’s large and straightforward to navigate with tabs for the home screen, live TV, your videos, movies, TV, apps and settings. Despite all its flaws, the JVC isn’t irredeemably bad. The Fire TV interface is very likeable despite its more sluggish moments, and being able to tell Alexa what you want to watch is a big plus. It’s all wonderfully easy to use, too, and the one-box simplicity may prove a big selling point to some buyers. Both techniques use an LCD screen that emits no light by itself. The difference is in the lighting behind the screen. With LCD screens this is done by CCFL (cold-cathode fluorescent lamp) and LED makes use of LED lights.

Often a remote control of a television will also work on similar models of the same brand. However, it is unusual that it will work on all models of that brand. Universal remote controls are more suited to do this. This partially depends on personal preference, but as a rule of thumb the optimal viewing distance is about 3x the diagonal screen size of the television. For a television of 60 inch (152cm) the optimal viewing distance would be 180 inch or about 4.5 meter. 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. In general you can connect a device like a blu-ray player or game console to any HDMI port. The device can then be used by selecting the corresponding HDMI channel on your television. To connect your universal remote control, you need the model number and brand name of both the remote control and the television. There is a list of codes for brands and model numbers in the manual of the remote control .The 4K display supports Dolby Vision and HLG HDR formats, and the speakers take advantage of both DTS HD and DTS Virtual X audio. But, how does it perform? Design Measuring the inches on your LED television is done by measuring the diagonal distance between for example the upper left corner and the lower right corner of the screen (not the edge). One inch equals 2,54 centimeter, so when you measure 99 centimeter, this means your LED television is 39 inches. At first, I tested this feature on a 1080p Blu-ray of The Martian, before moving on to a 480p and then an HD version of Arrested Development. Colours looked rather drab, which made the image less lifelike, although the upscaling overall was smoother and less noisy than that I experienced with the Hisense 50A7100FTUK. Sound quality The JVC LT-55CF890 features two 20W speakers that support DTS HD and DTS Virtual:X. Unlike the 50- and 65-inch models, there’s no Dolby Audio. However, DTS Virtual:X does a good job of creating a large, immersive sound. READ NEXT: The best soundbars and soundbases to buy JVC Fire TV Edition review: Price and competition

Turn off the television and wipe dust and dirt off the screen with a microfiber cloth. Do not use paper, this can cause scratches. Do not apply too much pressure or you might cause damage to pixels. Use a specialized detergent or make one by mixing 1 part vinegar with 1 part water. Moisten the cloth with the detergent and clean the screen. Make sure the cloth is not too wet. Remove stains by making rotating movements. Dry the screen with a second microfiber cloth to prevent stripes. 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. 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.

The presence of Dolby Vision is particularly good news for a budget model. ‘Dynamic’ HDR formats such as Dolby Vision are capable of adapting to the limitations of low-end 4K TVs, whereas ‘static’ HDR formats such as HLG and HDR10 rely more heavily on a TV’s natural talents. At this price, those talents are routinely in short supply. JVC Fire TV Edition review: Key specifications

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.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. Certain television settings may require you to enter letters. There are usually three letters or other characters on a button. When letter input is required, you can press that button once for the first letter, press twice for the second letter and press 3 times for the third letter. This way, text can be written with a minimum number of buttons. It looks like the tv that is on the 'Experts Review' is the older model not the new LT-65CF810 and its the 890 range.
