Go to SP road in bangalore.Its near Townhall. After entering SP road on de left side you wil find a shop with a big MX board who is the dealer for MX accessories in SP road. You wil get a good MX cable Cost not sure ,just inquire and bargain..
I have an unused DVI to HDMI adapter which I bought from ebay. This will work either way ie; DVI to HDMI or HDMI to DVI. Audio is not supported. You can also buy DVI to HDMI cable. If you have a spare HDMI cable, then you need to buy only a DVI-HDMI adapter. While buying, check for the number of pins in your DVI out. There are 29 pins and 24 pins variants.
