HDCP only apply for materials with that are copy protected....
Non-copy protected materials should play just fine...
You need to make sure that whatever video you are to play don't require HDCP-compliance hardware & software.
There are tools in the internet to disable HDCP requirement on copyright protected materials.
Buy the best LCD display with your money and use the available software tools from the internet to play your video.
The other option is use component-video as link from your video card to your TV. Component video can display 1080P just like HDMI. Its there is a difference in quality its something that most of use won't notice.
I tried both Component Video and HDMI to play Blue-ray and HD-DVD. Both work with 1080P. The quality is almost identical that if there is any most people won't notice.
Materials with copy-right protection enabled (HDCP Enabled) such as Blue-ray, HD-DVD require HDCP compliant Hardware and Software. You can't play these videos/audio at full 1080P without HDCP compliant hardware & software.
If your Hardware/software is not HDCP compliant, videos with copyright protection (HDCP required) will only play at regular-DVD resolution (480P)
