Hisense 65E78QTUK PRO review: big screen or better picture?

QLED is about colour: the quantum-dot layer helps the TV show a wider range of shades. It is still an LCD screen with a backlight, rather than an OLED whose pixels light up individually. Colourful animation, daytime sport and bright game worlds suit its strengths.

The bigger limitation is no local dimming . The TV cannot turn down the lighting behind a dark part of the picture independently of a bright part. In a night scene with streetlights or white subtitles, blacks can look more grey and the bright details have less impact. This is the difference to pay for if you love watching films with the lights off.

Dolby Vision and HDR10+ let it read those HDR formats, but the logos do not guarantee dazzling highlights. Independent European E7Q PRO tests describe relatively restrained HDR brightness. A bright explosion or sunlight glinting off a car will have less punch than on a capable Mini LED.

Reflections and off-centre viewing are weaknesses reported in E7Q PRO family testing. A window reflected in the screen can obscure darker scenes; colours and contrast also fade when viewed from the side. It is a more convincing choice opposite the sofa, with controllable daylight, than for a very bright room or a wide L-shaped seating arrangement.

The large picture makes players and the ball easier to follow from the sofa. Motion smoothing can make camera pans look steadier, although strong settings can introduce artefacts around moving players. The 144Hz panel is useful hardware; it does not turn an ordinary broadcast into 144 different frames per second.

Hi-View AI Engine handles picture processing, including sharpening and upscaling lower-resolution video to fit the 4K screen. That helps with HD programmes, but a heavily compressed stream still looks softer than a good 4K feed. At 65 inches, those source-quality differences are easier to see.

PS5 and Xbox Series X use up to 120Hz; the full 144Hz is for a compatible PC. The useful console upgrade over a basic 60Hz TV is access to supported 120fps game modes. Those modes usually trade some image detail for smoother movement and quicker-feeling control.

It also helps beyond competitive games. In Marvel’s Spider-Man 2 on PS5 , a 120Hz display enables the 40fps Fidelity option: smoother camera movement than 30fps while retaining the more detailed graphics mode. The game is running at 40fps, even though the TV receives a 120Hz signal.

VRR keeps the screen in step with changing game frame rates to reduce tearing. ALLM automatically selects the low-latency game mode. Together, these are more useful reasons to buy the PRO than the AI label.

Use HDMI 3 or 4 for high-refresh gaming. HDMI 3 also handles eARC, which sends TV audio to a compatible soundbar. With a soundbar on HDMI 3 and a PS5 on HDMI 4, HDMI 1 and 2 remain available for a Sky box or streaming stick.

That arrangement leaves only one high-refresh input free after adding an eARC soundbar. A household with both PS5 and Xbox cannot connect both directly at 120Hz while reserving HDMI 3 for sound; it would need a suitable HDMI switch or soundbar with compatible video passthrough.
