Usability
Thankfully, the UE48HU7500 is fitted with a quad core processor. Since it's handling four times the pixels as well as that Smart Hub cache of apps, this is great news – and it works well. Navigating the UE48HU7500 is a cinch, while loading-up apps is quick and easy.
Both remote controls talk to the mother ship quickly, though personally I'm not a huge fan of the 'smart touch' remote; as well as being small and over-engineered, it's home to a microphone for the frankly unappealing and ineffective smart control feature.
Multimedia
Critically for a TV that purports to be an Ultra HD 4K-ready, the UE48HU7500 can handle MP4 files with a 4K resolution encoded in H.264. If that's good to know, so too is the UE48HU7500's support for a wide range of more common file formats like AVI, MKV, AVC HD, MPEG-2, MPEG-4, MOV and WMV.
The UE48HU7500 also supports JPEG photos and music file formats that range from MP3, M4A and WMA to lossless filetypes like OGG, FLAC, WAV, AIFF and even APE, via a USB stick or a home network. That kind of comprehensiveness has niche appeal, but it's welcome nonetheless.
The UE48HU7500 also plays nicely with Samsung's SmartView 2.0 app, which creates a second screen on a smartphone or tablet for streaming files (MOV and MP4 video and JPEG photos) or porting live TV. It's possible to watch live TV on a tablet through SmartView 2.0 with barely a few seconds delay, though it's not possible to do the same with a DVD or Blu-ray disc.
Sound
Built-in audio is, thankfully, rather impressive. There's enough welly to make all of the TV's audio presets usable, though I settled on the music option for its all-round clarity. There's a movie preset also, though dialogue tends to muffle. There's also a TV sound connect mode to link a Bluetooth speaker, which is a nice option.
Value
The UE48HU7500 represents Samsung's mid-range Ultra HD option but it includes enough high-end end tech, as well as a slinky design, to make its price-tag palatable.
If you're after a real Ultra HD bargain, consider Samsung's 40-inch UE40HU6900 or its 50-inch UE50HU6900 in the step-down Series 6, though both have the same problem as this 48-incher; they're just not big enough to may 4K truly worthwhile.
