DVI-I, having the capacity to
carry both digital and analog signals, can be used to
connect an analog output to an analog input, or a digital
output to a digital input only. Take note that a DVI-I
cable cannot connect a digital output
to an analog input or vice versa. A DVI-I plug will accept
any type of DVI cable, DVI-I,
DVI-D, or DVI-A, but you must
make sure that your source and display are both using the
same format for it to work. Also, DVI-I, as with DVI-D,
comes with either a single or a dual
TMDS link.
Single
TMDS link DVI cables can support resolutions and timings
that use a video clock rate of about 25-165 MHz. A
dual link DVI-I cable, on the other hand, will handle up to
330 MHz and is backwards compatible with single link.
Thus if you are unsure which type you need, the dual link
will work where the single link may not. In order to
determine your required bandwidth just multiply your desired
resolution by your desired refresh rate (ie. 1600x1200 x 70
= 134 MHz). |
