Line 157:

** Used for the mandatory "low pixel format" display mode: [[VGA (resolution)|VGA]] (640x480) @ 60 Hz

* Maximum single link TMDS clock frequency: 165 MHz

** Single link maximum [[gross bit rate]] (including 8b/10b overhead is): 4.95 Gbit/s. With the 8b/10b overhead subtracted, the maximum [[net bit rate]] is 3.96 Gbit/s.

** [[Net bit rate]] (subtracting 8b/10b overhead): 3.96 Gbit/s

** Dual link bit rates are twice that of single link at an identical clock frequency. Including 8b/10b overhead, the maximum gross bit rate at 165 MHz clock is 9.90 Gbit/s. With the 8b/10b overhead subtracted, the maximum net bit rate is 7.92 Gbit/s.

* Dual link bit rates are twice that of single link at an identical clock frequency.

*** Clocks above 165&nbsp;MHz are allowed in dual link mode{{notetag|and only used when total bandwidth requirement surpassing 330MHz TMDS clock. The specification only specifies first link to operate at above single-link maximum in such scenario.<ref name=DVI1.0 />{{rp|§2.2.2.}}}}

* Bits per pixel:

** 24 bits per pixel support is mandatory in all resolutions supported.
