Actually, there is a significant difference in HDMI cable quantity. Different cables are rated to handle larger amounts of information than others, and higher quality cables are better. Monster can explain this better:# tandard Definition Progressive Scan video from components, such as high-end DVD players and game consoles, introduced a data rate of .81 Gigabits per second at 60Hz scan rate with 8-bit color depth. Progressive scan video is available via component video connections.
# From Standard Definition to today's High Definition HDTV (High Definition Television) as we know it today introduced higher resolutions of 720p (progressive) or 1080i (interlace). Both are High Definition. With high definition, data rate increased from 0.81 Gbps to 2.23 Gbps, almost three times the amount of data per second.
The single digital connection launches: HDMI 1.0
# From High Definition to "Higher Definition" Going beyond HDTV resolution, new formats such as HD DVD and Blu-ray Disc players now enable the best HD has to offer today: 1080p content. Many manufacturers have their own saying for this, such as "True HD" or "Full HD."
The data rate is double that of HDTV, 4.46 Gbps. Many HDMITM cables can't support this, especially at longer lengths. Enter a new High Definition Multimedia Interface specification of 1.2 and 1.2a, which also introduces support of high-resolution SACD and DVD-Audio (192 kHz/24-bit resolution over eight channels). Certainly, that's an incredible amount of data to travel down the same cable.
# From Higher Definition to "Ultra-High Definition." As technology advances, content and sources will enable picture and sound that goes beyond the best HD has to offer today. Higher frame/refresh rates (120 Hz compared to today's 60 Hz) remove jitter for a smoother, more lifelike picture. Advances in color will reproduce all the colors the eye, exceeding even 10-bit and 12-bit Deep Color, sometimes also referred to in the PC world as 30-bit and 48-bit color (10 or 12 bits each for Red, Green, and Blue.
Large high definition displays with larger pixels make video imperfections all the more obvious. Deterioration of data caused by lesser-quality HDMITM cables can be seen more easily on larger displays. Artifacts, such as color banding and contouring, also become more visible on larger displays. In addition, motion artifacts at the slower refresh rate of 60 Hz are more visible, as are the smooth motion enhancements in faster-refreshing 90 Hz and 120 Hz displays.
Many HDMITM cables being sold do not meet actual HDMITM cable specifications. Often cables are acceptable for 1080i video but not 1080p video, requiring double the amount of throughput. Often picture degradation and artifacts that have been attributed to displays and sources are actually caused by poor cable performance.
Yes, that is taken from Monster's website, but it's true. Pattern tests also show that higher quality cables are able to carry signal with less interference and distortion.
