You get 'INVALID FORMAT' because the video signal source resolution is too high for the TV to display, you need to lower your video source resolution.

My tv says invalid format when i connect my ps3 using an hdmi cable


Your PS3 is sending a 1080P signal to a TV that can only handle 720P or 1080i. Connect the PS3 using the A/V cables, fix the resolution and then go back to HDMI.

Hdmi is connected, but invalid format is displayed on the TV


Check HDMI cable over version 1.3. If the HDMI cables you use don’t support HDMI version 1.3, it can cause flickers or no
screen display. In this case use the latest cables that support HDMI version 1.3.

Hdmi inputs stopped working


It sound like the cable box or the Blue ray player is set to high - such as 1080P when the set is only rated at 720 - try scaling the output down and see if that helps

Cannot play video games downloaded


I was getting the same problem with my lcd tv. I was using a DVI to hdmi cable to connect the pc to the tv. I switched to a vga cable and I was able to finally get into the game. Once you get into the game make sure you change all the video settings to be compatible with your tv i.e. resolution for a 720p set should be 1366x768 on the game resolution, and you should also change the refresh rate to 60hz in the game if that is the max. on your tv.

Once you do this, you can then put your hdmi cable back in and get into the game. Every game I install I have to first run using the vga cable, and then switch to HDMI.
