What is the Samsung UE48HU7500?
We’ve already spent some quality time with the 55-inch HU7500, now it’s time to see how the 48HU7500 carries the Ultra HD resolution in its smaller chassis.
Design & Connections
The 48HU7500 doesn’t come with Samsung’s future-proofing One Connect Box but it is compatible so owners can upgrade as and when standards evolve. In the meantime, there are plenty of connections including 4 HDMI ports, three of which face sideways with the other pointing outwards at the back. We also get support for legacy video connections, an optical digital audio out and both wired and wireless LAN.
Samsung UE48HU7500 Calibration
The default settings of the Movie mode provided a familiar pre-calibration set of results with red tracking low in the greyscale and a slight excess of green and blue as a result. In terms of visible errors, our highest is for peak white but at just above 5 for its delta value, it’s nothing too bad. We’d like gamma to be tracking closer to our target of around 2.35 (for this panel) but all the tools are there to get it how we want during the calibration. The out of box colour performance was even more impressive with the highest delta E coming in at under 3, for red, which is considered by most to be the threshold at which the human eye can detect errors.
After a nightmarish experience last time out with the Philips PFS6609, it was refreshing to be at the helm of some well thought out and brilliantly implemented calibration controls. It was with some ease that we were able to obtain reference grade results for greyscale and we got gamma tracking exactly as we had targeted.
The 48-inch HU7500 wasn’t quite so impressive as its larger stable mate when it came to outright black levels but only by a fraction and they were very pleasing in any case. From a chequerboard pattern – which gives a decent indication of contrast performance with real world content – we clocked average black levels at 0.056cd/m2 against an average peak white of 120.4 cd/m2 giving an ANSI performance touching 2170:1. That’s actually a higher contrast ratio than the 55HU7500 because it holds on to its whites a tad better. More good news is that the screen uniformity was superb on dark screens, with or without Smart LED dimming employed, but it’s such a good example of local dimming you’d be silly not to use it. We preferred the default ‘Standard’ configuration as ‘Low’ doesn’t offer much over the native performance and ‘High’ blows out the paler shades.
It would have been pretty shocking had the 48HU7500 not behaved identically to the 55-inch in this section of testing. Of course it was the same which means the crucial ability to scale lower resolution signals to match the 3840 x 2160 panel was performed extremely well. Both video deinterlacing and film cadence detection were very solid, too, and there were precisely zero issues in the handling of 1080p24 content. We’ll leave it down to readers discretion as to if they wish to experiment with the Motion Plus frame interpolation processing but provide you don’t push it beyond ‘Clear’ or a conservative ‘Custom’ setting you may find it helps with motion handling with fast paced video content, such as sport. We would never advocate spoiling your Blu-rays with it and we actually never found the need to engage but some will.
Surprisingly there was a difference in the lowest achievable input lag with the 48-inch HU7500 and it was a change for the better. By editing the input label of one of the HDMI inputs to PC, we got a measurement of 45.2 milliseconds, which is quite considerably better than the 55-inch managed. For the record, activating the Game mode in the System Menu – which actually takes longer than editing the input – only gets latency down to 77ish milliseconds, which is higher than the 66ms the 55HU7500 managed with the same setup. We’re not sure if it’s a software update that’s responsible but, whatever it is, Samsung should really make their lowest latency modes more accessible.
• Standby: 0W
The following measurements were taken with a full screen 50% white pattern:
• Out-of-the-Box – Normal Mode: 77W
• Calibrated – Movie Mode: 74W
• Calibrated - 3D Mode: 114W
Samsung UE48HU7500 Picture Quality
Perhaps ironically, the biggest question mark is over the 48-inch model being able to portray Ultra HD resolution as a meaningful upgrade over 1080p, from a ‘sensible’ sitting distance. We only have limited material with which to test this out, at present, but at least we have some, thanks to Netflix. Comparing a selection of scenes from the second season of House of Cards - via the Netflix 2160p feed and the UK release of the Blu-ray – we’d have to say there’s virtually nothing in it from anything outside 6 feet, in terms of picking out the finest of details but, as we’ve thought before, the increase resolution gives advantages in other areas such as a look of better textures and a slight increase in dynamic range. The extra pixels give a bit more finesse to light and shading which just narrowly eclipses the Blu-ray transfer but we would have liked a bit more screen real estate to play with, no doubt. We’re going to follow this review up with a more detailed piece on the subject but the short version is – you’ll be gaining a little polish to your pictures but you’ll need to drag the armchair up close if you want to see more fine detail.
The other concern, and something we experienced with the first gen of 4K TVs, is that you’re losing out with Full HD resolution content. This was particularly the case with 1080i material when the combined duties of deinterlacing and scaling proved too much for most. The HU7500 copes with these demands much better but still with faster paced action, such as sports broadcasts, the loss of resolution under motion is just that bit more palpable than it is with a better 1080p panel. Not enough that it would put us off – and we like our sports – but we can’t wait for the day we’re seeing live 4K action broadcast at better frame-rates.
Draw from that what you will. Samsung continues to fly the flag for active shutter 3D technology in excellent fashion. Images are suitably bright and believable in the 3D movie mode and there’s all the pop-out and depth you could wish for. There’s a little crosstalk here and there and it’s that bit more obvious on the 4k panel than it would be on a Full HD equivalent but it was more than good enough for our limited 3D needs. We also have to remark at the lack of perceptible flicker as it’s something we often suffer with this technology.
- Excellent black levels and contrast
- Superior dimming system
- Colours near perfect
- Gorgeous design
- Truckloads of smart features
- Almost all major VoD & Streaming services present
- Perhaps 48-inches is a tad small for 4K
Samsung UE48HU7500 (HU7500) Ultra HD 4K TV Review
You probably do want to take advantage of those LAN connections too, especially as the Samsung Smart Hub brings with it access to the Netflix 4K Ultra HD service, which is just about the only game in town when it comes to actual content to take advantage of the increased resolution present in the HU7500. There’s tons of other smart features too and Netflix is joined by all the major UK catch-up services, YouTube, Amazon Instant Prime and much, much more besides.
But that’s all just the icing on the cake as when it came to producing superb pictures, the HU7500 had it in spades. Once we’d calibrated, colours were natural and alive whilst blacks were deep and convincing, aided by a dimming system that allows shadow detail and dynamic range to flourish. The Netflix content of course looked sublime, although we would have preferred a slightly larger screen with which to appreciate it, but even lesser resolutions looked great and we doubt you’ll have the sense you’d be losing anything in comparison to your 1080p set. More the opposite, in fact.
Samsung has been hitting it out of the park in 2014 and the 48HU7500 is another in their procession of TV excellence. Highly Recommended.
