Your TV does not support HDCP, the actual hardware can not do it. Here is more detail on it:

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation [1] to prevent copying of digital audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), or Unified Display Interface (UDI) connections.

HDCP does not allow copying permitted by fair use laws. The system is meant to stop HDCP-encrypted content from being played on devices that do not support HDCP or which have been modified to copy HDCP content.[2][3] Before sending data, a transmitting device checks that the receiver is authorized to receive it. If so, the transmitter encrypts the data to prevent eavesdropping as it flows to the receiver.[4]

Manufacturers who want to make a device that supports HDCP must obtain a license from Intel subsidiary Digital Content Protection, pay an annual fee, and submit to various conditions.[5][6][7] For example, devices cannot be designed to copy content; devices must "frustrate attempts to defeat the content protection requirements"[7]; high-definition digital video sources must not transmit protected content to non-HDCP receivers; and DVD-Audio content can only be played at CD-audio quality[7] by non-HDCP digital audio outputs (analog audio outputs have no quality limits).


Basically whatever you are trying to play has HDCP enabled on it, and your TV can't display it.

So sorry about that :(

Hi, Simply attaching the cable isn't always enough. Sometimes you actually have to tell the laptop to display via HDMI or DVI onto your external monitor or it will not output any signal.

Try pressing Windows Key+P, this will change your presentation settings in Windows (What screens you get a display on and how they are displayed). Cycle through to either "projector only" or "duplicate screens" and see if you get a display on your TV then.

I have a Philips 47" flat screen it has HDMI


First of all you must check that your laptop supports a protocol called "DHCP" over DVI. Otherwise you are chasing your tail. This information will probably be in the manual or available online. DHCP is a special handshake protocol for HDMI and your television and computer will not talk to eachother without it. If you find it to be compatible you need to lock down which input on the TV it is. Plug something in via HDMI and verify you see it. Then unplug it and plug your computer into this port. You don't want to be flicking through inputs trying to find it. Also, hook up an external monitor to the laptop and figure what needs to be done to display on it. Then try the television. My guess, though, is that you won't find DHCP compatibility if it is an older laptop. My best advice is to buy a Playstation 3 and watch Netflix with that. Otherwise you'll need a different way of hooking up which might include buying an expensive converter box and/or watching poor quality video.
-Good luck

My neighbor bought a 32"


Unless the tv has a VGA input, or the laptop has a HDMI output, I am afraid you are going through too many conversions to make this work.

Screen is all Green


New cable box recently? If not, your cable provider has probably pushed a firmware update to your cable box. Green screens are very common with HDMI connection. From your symptom, I am going to take a guess that you are connected via HDMI. If so, switch to Component cables and your problem is solved. It's not the TVs fault... cable boxes seem to be the single largest problem child for HDMI compatibility. I hope this was of some assistance.

Hdmi and audio


It may be the top of set box.. Most times the sound and picture are auto detected by the set when HDMI is used. Both sound and video are carried in a HDMI cable but not with a S video cable. Try another HDMI cable *** dont buy the expensive one the tv don't care if they cost $125 or $25.

Phantom horizontal upward-scrolling lines... from a PS3 with HDMI to DVI


Everything works better on component, I know the salesman at the store says its better, but its not....I tell customers all the time (I could hook up three tvs side by side..HDMI-DVI-Component and the human eye cannot tell the difference) The reason the DVI and Hdmi were created was for copy guard encription....Although the component is an analog signal, it goes to a A/D conversion..........But this is just my insane opinion...Good Luck

Screen flicker when watching 1080i


Component video has a max resolution of 720p. in order to use 1080i or p you have to use hdmi or dvi connections. That is why you get the flicker.

Philips 32' lcd hdtv


are you using a DVI to HDMI converter? Radeon cards older than x1*** series or roundabout didnt support hdcp on dvi which is required to run Hi-Def rez thru an HDMI cable on most TVs. A video card with hdmi prebuilt in or HDCP compliance listed on the box should be able to handle it. And you should find a resolution both your normal monitor and HDTV can handle to set the coimputer to before you switch it over to the HDTV to be sure it will still show you picture. If you arent using 1080P you might as well use a component input which doesnt require HDCP.
