HDTV Resolutions
The resolution of a high-definition television set defines the maximum number of lines of pixels or dots the screen has that can be illuminated by a scanning beam. The beam can scan the odd lines in one sweep and the even lines in the next sweep using interlaced (i) scanning, or it can sweep all lines in a single sweep using progressive (p) scanning. HDTV sets are designed with 720p, 1080i or 1080p scanning. The set converts any signal it receives to fill the screen to its designed resolution, but sometimes with black spaces on the edges at lower resolutions.
PS3 HDMI Output
A PS3 has an HDMI output that produces any resolution that an HDTV can read. When connected, the PS3 uses control signals to communicate with the HDTV to automatically adjust the output to the screen's designed maximum resolution. To send 1080p resolution, the HDTV must have that option in its design capability. Other PS3 resolutions include 1080i, 720p and 480p; the console will automatically select whichever it needs to conform with the HDTV design. Select the HDMI output in the "Video Output Settings." See your owner's manual.
HDMI
Developed in 2002, High-Definition Multimedia Interface technology provides a single-cable connection for digital video, up to eight channels of audio and various control signals between the components of home entertainment systems. With version 1.4 of 2009, HDMI became the industry standard connection, and ports now appear on most HDTV sets and Blu-ray players. High-end DVD players, A/V receivers, video game consoles and computer video cards also carry the format. HDMI also provides an Ethernet channel for Internet connections to any component in the system.
HDMI Cable
The HDMI licensing authority specifies five types of HDMI cables. Standard (category 1) cables carry signals up to and including 1080i resolution, with or without the Ethernet option. High-speed (category 2) cables carry signals of 1080p and higher resolution, with or without an Ethernet option. A more rugged standard version makes connections in automotive applications. Some manufacturers produce cables that exceed current HDMI licensing requirements in anticipation of future equipment needing them; however, these cables won't improve your PS3 setup. For the best setup, use licensed HDMI high-speed cables, and if you want to connect to the Internet, choose the Ethernet option.
