relatively unprocessed and want the other speakers to conform, tonally, to them. ‘Engi­neering’ makes the sound match ‘the Sony listening room standard frequency charac­teristics’. (I got that from the online manual. The information you need is split between the printed one in the box and the online manual.) Finally, in ‘Sound Effect’ is a Pure Direct setting. As well as offering room-shaking power, the Sony STRDH790 is also compatible with High-Resolution Audio. This offers a sound that's far more natural sounding than standard audio. The STR-DH790 also supports DSD formats – with a sampling frequency that’s 64x that of conventional CD, for stunningly detailed sound. Dolby Atmos® processing for use with in-ceiling or "height" speakers for more enveloping surround sound

There were some wrinkles with the HDMI equipment I used. Specifically, neither of my Beyonwiz PVRs would work with the HDMI input labelled BD/DVD. Both worked perfectly with the Game and Media Box inputs. The Beyonwiz T4 also worked with the SAT/CATV input, but while the picture came through from the T3 on that one, the sound wouldn’t. I tried different HDMI cables. Who knows what was going on there. The BD/DVD input worked fine with the Sony disc player (above) and my own selection of UHD and Blu-ray players. A useful button on the remote displays video and audio signal information on the screen, so you’ve got some information to work with. If you are unsure about whether to choose STR-DH790 or not, please read this comprehensive review to the end as we highlight its important features with pros and cons. Sony STR-DH790 Review

According to the specs they support up to 4K and UHD at up to 60Hz, HDR10, Hybrid Log-Gamma and Dolby Vision, 3D, Deep Colour, the BT.2020 colour space, and the all-important HDCP 2.2 copy protection system. There’s a single HDMI output. There is a time gap between the visual display on the TV and the audio output from the speaker connected to the receiver. Dolby surround sound is one of the most widely used processing formats today and offers various options to get the most from audio sources.
