Hi folks,

I'm looking for a video card to drop into a PC to output video to my 1080p Panasonic, and have read around here that an DVI-to-HDMI cable may be a good way to go.


But, I read on wikipedia that I'll need a DVI "dual link" to support my hdtv's 1920x1080 resolution. If this is true, does that mean that this cable won't work?








The excerpt from the wiki article on DVI:






* Example display modes (single link):

o HDTV (1920 × 1080) @ 60 Hz with CVT-RB blanking (139 MHz)

o UXGA (1600 × 1200) @ 60 Hz with GTF blanking (161 MHz)

o WUXGA (1920 × 1200) @ 60 Hz with CVT-RB blanking (154 MHz)

o SXGA (1280 × 1024) @ 85 Hz with GTF blanking (159 MHz)

o WXGA+ (1440 x 900) @ 60 Hz (107 MHz)

o WQUXGA (3840 × 2400) @ 17 Hz (164 MHz)


* Example display modes (dual link):

o QXGA (2048 × 1536) @ 75 Hz with GTF blanking (2×170 MHz)

o HDTV (1920 × 1080) @ 85 Hz with GTF blanking (2×126 MHz)

o WQXGA (2560 × 1600) @ 60 Hz with GTF blanking (2x174 MHz) (30" Apple, Dell, HP, NEC, Quinux, and Samsung LCDs)

o WQXGA (2560 × 1600) @ 60 Hz with CVT-RB blanking (2x135 MHz) (30" Apple, Dell, HP, NEC, Quinux, and Samsung LCDs)

o WQUXGA (3840 × 2400) @ 33 Hz with GTF blanking (2x159 MHz)




The cables I've been able to find have only the pin configuration of the "DVI-D single link". Will this handle a 1920x1080 resolution from the video card?

If some of you kind folks could enlighten me on the subject before I buy a video card / dvi-hdmi cable, I'd much appreciate it!

You answered your own question in your quote. You only need single link for 1920x1080 at 60 Hz. The only practical situation where you will need dual link is 2560x1600 at 60 Hz.


You'll be fine.
