Topic: Nintendo's HDMI cable included with Wii U

I am having a weird wonder what is going on with the thing. It only works with Wii U. I tried to hook it up to my laptop to display my screen on my TV and nothing happened when I told the laptop to project it's screen on TV.
It's an HDMI cable, right? Is nintendo using some secret code blocker on the HDMI cable making it impossible to use on anything but the nintendo systems?

I've used my HDMI cable to do the exact thing you're talking about. Are you sure you're setting your laptop up to project the image?

Double check the TV's channel/settings/whatever, because I used it before with my computer.

I have it connected to HDMI 1 and it should be working. I press windows button + P to show the Projection settings.

I have hooked up my laptop to the tv with the Wii u HDMI cable with zero problems.

You can't always trust those key commands, since they are being controlled by a driver that may not work.
Better to go into the graphics options for your card and set it manually, at least to see if it actually works. Then try and solve the key commands program.

Well...my brother got me an Xbox 360 recently, but it only had Composite cables. It's currently using the Wii U's HDMI cable while the Wii U is using the Wii's Component Cables. Beautiful picture on both.
