The Hisense E78Q 55″ 4K Ultra HD QLED Smart Freely TV is a feature-packed 2025 set that aims to bring premium-looking pictures and next-gen gaming to a sensible mid-range price. With a 55-inch QLED panel, Dolby Vision IQ and Dolby Atmos support, it’s clearly designed for movie nights as much as everyday telly.
Hisense has built a strong reputation for offering a lot of tech for the money, and this model follows that pattern. You’re getting 144Hz refresh, FreeSync Premium and a dedicated Game Mode Pro, plus Freely built in so you can watch live TV over broadband without an aerial.
With a 4.7 out of 5 rating from hundreds of owners, it’s a well-reviewed choice that clearly lands well with most households looking to upgrade from an older LCD or basic smart TV.
This 55-inch Hisense is ideal for families and film fans who want a big, cinematic picture without paying premium-brand prices. The QLED panel with Quantum Dot colour will be a clear step up from older HD or basic 4K sets, especially in living rooms where you watch a mix of streaming, sport and regular broadcast TV.
Gamers are an obvious target here. The 144Hz Game Mode Pro, low 6 ms response time and FreeSync Premium support mean it pairs very well with modern consoles and gaming PCs, delivering smoother motion and reduced tearing compared with standard 60Hz TVs.
It also suits households that don’t have or don’t want a rooftop aerial. With Freely on board and a full digital tuner as backup, you can watch live and on-demand TV over your broadband connection. Add in Apple AirPlay 2, Alexa compatibility and screen mirroring, and it fits nicely into a connected home where you’re already streaming from phones, tablets and laptops.
If you’re after reference-level brightness or have a very big, light-flooded open-plan space, you may want to look at higher-end, brighter models. But for most UK lounges and budgets, this hits a very comfortable sweet spot.
The QLED panel with Quantum Dot colour produces rich, vibrant shades that hold up well on 4K content, making films, sport and nature documentaries look far more lifelike than on standard LED sets.
Dolby Vision IQ and IMAX Enhanced support mean you’re getting modern HDR standards, with the TV’s Hi-View AI Engine automatically optimising picture settings for the content and lighting, so you spend less time fiddling with menus.
For gamers, the 144Hz refresh rate, FreeSync Premium and Game Mode Pro are big advantages. They help keep fast action smooth and responsive, especially with compatible consoles and PCs.
Freely built in lets you watch live TV over the internet without relying on an aerial, which is particularly handy in rentals, older properties or rooms without a TV point. You still have a full digital tuner if you prefer a traditional connection.
Four HDMI ports (with eARC), two USBs, Wi-Fi, Bluetooth 5.0 and Apple AirPlay 2 make it easy to hook up soundbars, consoles, streaming sticks and cast from your phone, so you’re well covered on connectivity.
The typical brightness of 330 nits is fine for most lounges but not outstanding; in very bright rooms with large windows, HDR impact will be more muted than on higher-end, brighter QLED or OLED sets.
The built-in 20W 2.0-channel speakers are adequate for everyday viewing, but they won’t fully do justice to Dolby Atmos soundtracks. A separate soundbar or AV setup is strongly recommended if you care about audio.
The energy rating is E, and HDR consumption is relatively high at 110 kWh per 1000 hours, so it’s not the most efficient choice if you’re very focused on running costs.
Hisense’s VIDAA smart platform is straightforward enough but not as polished or app-rich as the very best from some premium brands, which might matter if you rely heavily on niche streaming services.
Day to day, the Hisense E78Q is designed to be straightforward to live with. The 55-inch flat QLED screen sits in a relatively slim 8 cm chassis, and the included desktop stand has a 973 mm width, giving a stable base on standard TV units. If you prefer it on the wall, the 200 x 400 mm VESA mount pattern makes it compatible with a wide range of brackets.
The VIDAA smart interface brings together streaming apps, Freely and inputs in a simple home screen layout. Voice control support and Alexa compatibility make it easy to launch apps or change settings without hunting through menus, and Apple AirPlay 2 plus screen mirroring mean guests can quickly share content from their own devices.
Useful everyday touches like a sleep timer, timeshift, electronic programme guide and built-in web browser make it practical for regular broadcast and catch-up TV. The Hi-View AI Engine automatically tweaks picture modes depending on what you’re watching, and there are dedicated Filmmaker and Game modes when you want something more specific.
Setup is helped by the included instruction booklet and quick start guide, with all the basics in the box – including the remote control and the necessary cables – so you can get up and running without extra purchases.
Picture performance is the main attraction here. The 55-inch 4K Ultra HD QLED panel, backed by Quantum Dot Colour and an LED backlight, delivers sharp 3840 x 2160 resolution with a wide DCI-P3 colour gamut. Combined with Dolby Vision IQ, HDR streaming support and IMAX Enhanced certification, it’s well set up for modern 4K movies and high-quality streaming content.
While its typical brightness of 330 nits isn’t class-leading, the TV’s MEMC motion processing and 144 Hz panel help keep fast content smooth. Sport, action films and games benefit from reduced blur, and the wide 178-degree viewing angles mean colours and contrast remain fairly consistent when you’re not sat dead centre.
Gaming is a real strong point. Game Mode Pro, 144 Hz refresh, FreeSync Premium and a 6 ms response time work together to minimise lag and tearing with compatible consoles and PCs. The dedicated Game Bar overlay gives quick access to key settings, making it easier to optimise on the fly.
On the audio side, the set supports advanced formats including Dolby Atmos, DTS:X and Dolby MS12, so it can pass immersive soundtracks through eARC to a capable soundbar or receiver. The built-in 20 W stereo speakers handle everyday TV and casual viewing, and you can fine-tune things using the equaliser.
Smart and connectivity features are comprehensive. VIDAA powers the smart TV experience, with support for HDR streaming, HbbTV 2.0.4 for hybrid broadcast services, web browsing, screen mirroring and a decent app selection. Four HDMI ports, two USB ports, Ethernet, Wi-Fi and Bluetooth 5.0 give plenty of options for external devices, while Apple AirPlay 2 and Alexa integration help it fit neatly into a modern connected home.
At this price, the Hisense E78Q sits firmly in the mid-range, yet its spec sheet edges into territory that some brands reserve for pricier models. A 144 Hz QLED panel, Dolby Vision IQ, Dolby Atmos support, FreeSync Premium and Freely built in make for a very competitive package for the money.
The energy rating and average brightness show where some compromises have been made, but for typical living room use the overall experience is still very strong. You’re getting future-friendly connectivity with four HDMI ports and eARC, plus robust smart features and casting options.
A user rating of 4.7 out of 5 from a large number of reviews strongly suggests that most buyers feel they’ve had excellent value. If you want top-tier image and gaming features without stretching to premium-brand prices, this model represents very solid bang for your buck.
The Hisense E78Q 55″ 4K QLED Smart Freely TV is a highly capable all-rounder that blends impressive picture quality, strong gaming credentials and modern smart features into a sensibly priced package. QLED colour, Dolby Vision IQ and the Hi-View AI Engine give films and TV a punchy, polished look, while 144 Hz and FreeSync Premium make it a genuine step up for gamers.
Its main compromises are moderate brightness, average in-built audio and an energy rating that’s not the most frugal, so picture purists in very bright rooms and those chasing the very best sound will want to budget for a soundbar or look further up the range.
For most households, though, this is a smart, future-ready choice: a 55-inch TV that feels modern, performs well across the board and offers standout gaming features for the money. If you’re upgrading from an older 4K or HD set and want a big, capable screen without overspending, it deserves to be high on your shortlist.
