Upscale

Upscale adds ‘like’ pixels to the image. So, if you were upscaling a yellow banana, it adds more yellow pixels all around the single yellow one. The trick is edge sharpening where the banana delineates onto a background.

The lower the source content, the more pixels it must add. Upscale does not add detail, e.g. 4K is 3840 x 2160 (8,294,400 pixels)

  • 1280x720p (921,600 pixels) means the TV makes up (inserts) 7,372,800 extra pixels
  • 1920 x 1080 (2,073,600 pixels) means the TV makes up 6,220,800 pixels.

We tried it with a variety of content from old 480i black and white to 1080p. While it was a ‘stretch’ to upscale 480/576/720 (grainy) to 4K, 1080p content upscales very well.

The TV has enough processing power to analyse each frame and intelligently add pixels and sharpen edges.

Casting

Any Miracast or Wi-Di device (many Android and Windows devices) will cast to the screen. Apple iPhone requires an Apple TV box to cast to the screen. Some Google/Chrome devices require a Chromecast HDMI dongle.

How does it sound?

The system has Harman Kardon Acoustic Design speakers. This unit has 2 x Tweeters, 4 x Mid and 4 x Woofer (total 10). Six of these are backfiring (or at least ported to the rear) and require a surface (like a wall) to bounce off. Initially we put it on a bench and the sound was a little ‘off’. We placed a surface behind it then things got interesting.

Without the wall bass kicked in at 180Hz and was relatively flat to 5kHz. This is a mid-sound signature best suited to voice. It is a little thin!

With the wall behind bass kicked in at around 100Hz, and it was flat to about 10kHz. This is more a warm and sweet sound signature – easy to listen to.

Maximum volume was 80dB with a small amount of distortion.

We were also testing the JBL Bar 5.1 (GadgetGuy review here) and Sonos Beam (GadgetGuy review here) soundbars. These are subject to a separate article. Suffice to say that the JBL with its separate sub-woofer really shook the house with bass kicking in at 40Hz. Sonos was at 80Hz.

There are also presets – standard, theatre, music, speech, late night and sports. It is pretty hard to alter a native sound signature too much but these act as an EQ adding slightly more bass, mid or treble.

It also has adjustments for surround sound (psychoacoustic processing) to place sounds beside, behind and above the viewer.

The moral of this story – buy a good soundbar for the best sound. The TV sound is fine for an average lounge.
