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 TV with stand: 762 x 1243 x 227 mm (H x W x D) - Stand: 18 x 600 x 227 mm (H x W x D) - Boxed: 860 x 1369 x 154 mm (H x W x D)
The Omni QLED may not have the best picture on the market, but considering its price range, I was surprised with just how detailed and vivid its picture was and how well it punches above its weight.
The Amazon Omni is almost certainly going to be a Black Friday bargain
The first thing you need to know about 4k resolution is that not all media are uploaded or streamed in 4k. 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. Otherwise, try restarting your router by unplugging it from the power source and turning it on again after a minute. My JVC TV Pixelates or Stutters 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. Our testing has shown us that a long list of features doesn't necessarily make a good TV. A screen capable of displaying 4K resolution may be terrible at showing HD content.
We don't test every supermarket or electronic retailer own-brand TV, but to give you an indication of whether it's worth buying one of their TVs, this table shows the average Which? test scores of TVs from many of the brands you'll find in supermarkets and electronics retailers, alongside those of the market leaders. In terms of menus, the main Fire TV menu is easy enough to navigate through but changing settings such as picture mode, input and so on is not as easy compared to other smart TV platforms. To access these settings, you have to hold down the home button rather than a settings button, which definitely slows down the process.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. You won’t have a problem finding the right app for your interests. It’s most likely available on the Google Play Store.
You can try fixing the location for those using digital antennas to see if it improves the signal. My JVC TV Turns On and Off at Random 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 The JVC Fire TV Edition is a 4K HDR TV though, and therefore supports the HDR10 standard, as well as the dynamic Dolby Vision HDR format. However, we’ve found that cheaper sets generally struggle with premium Dolby formats – either to draw out the quality, or play the format at all – and you may not want to buy this set for that purpose. 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. Picture quality The price of store-brand TVs may certainly be tempting, as may what appear to be a wide range of features that, on paper at least, make them a match for the best Samsung and LG have to offer.When measuring the Delta-E values (the margin of error between an accurate test pattern source and what’s shown on screen), we typically look for the average result to be under 3, since this is considered indistinguishable from perfect to most people. When measuring grayscale results (to test how it handles different levels of darkness) in Movie Dark mode, the result was 4.3, so a little disappointing – but this is somewhat expected with an LED screen. However, in terms of color accuracy, the Omni QLED’s Delta-E average was 1.99, which is an excellent result especially for a TV at this level. It’s worth noting adjustments in picture can be made to improve those numbers, but these were the out-of-the-box results. If you attempt to change the resolution manually, you will get pixelation or stuttering on the video. A good example of this is YouTube. Not all the videos you see on YouTube are rendered and uploaded in 4k.
