They came to install Truevisions HD last Friday, and I have had the chance to sit down and watch a bit of it this afternoon. There are two new channels, which cost an extra 290thb per month. Quality looks good, especially on the sports channel, and HBO HD is passable, although not as good as downloads or Blu-Ray.
The highest resolution is 1080i, although the box can output at 576i (DVD quality), 720p (HD Ready) as well. Both channels have Dolby Digital sound and output at 1080i.
The box is a better looking effort than the Topfield we had before and required a further refundable 2,000thb deposit on top of the original 2,000thb deposit we paid for the basic decoder. It has HDMI output, Ethernet, optical audio and a USB slot in the back.
It will be worth it for the sports as they are going to show the World Cup in HD. Watched the highlight of Barcelona v Sevilla and the quality was superb. No ghosting or trails at all as with standard definition on a big screen LCD.
The menu system on the new decoder is also much improved and easier to use, and the normal standard definition channels look a little fresher as well.
