Windows 7: PC to TV through HDMI cable, PC refuses to detect TV

PC to TV through HDMI cable, PC refuses to detect TV

Hi everyone. I've Google searched everything I can on this, and I can't seemto find anything pertaining to my situation. From everything I have read, it should be as easy as "plug in HDMI cable, select output on TV, done." Well, it isn't that simple...

I have plugged the HDMI cable into my PC and routed it to my TV (Sony 32 inch 1080p LCD Bravia.) On the nVidia control panel, I go to Set Up Multiple Displays. Not a thing I do here gets my computer to see the TV, at all. I try to force detection, and nothing.

It works okay if I simply take the VGA connector from my monitor and put it into the TV. That works fine. I want to do this over HDMI so I can duplicate the displays, so that I don't need to constantly change the cable back and forth (so I can surf the net on my monitor, but when I want to play a game, I can do that on my TV.)

I'm at the end of my rope with this. Can someone figure this thing out?

You need to have the TV on set to HDMI

While the tv is set use the pc to detect the settings

It has be to on and on the HDMI channel for it to work

After the card has seen the tv and reconizes it a profile will be created

Also make sure it is in the first Hdmi not the second

After you have established a connection as long you dont put the system into sleep mode it will continue to show

The connection can be broken by a restart but..... this will make the bravia the main LCD because the card will reconize a bigger resolution

Hope this helps you

I changed it to HDMI 1 and it still doesn't detect anything. I've tried two TV's and two HDMI cables already.

Check if the TV may require a firmware update, some do prove to require it.

How would I even begin to do that? To my understanding firmware updates are downloaded through the internet and this isn't an internet connected TV... lol. I have no idea where to start doing that.

First make sure that the video card detects the PC, by unplugging the 22 inch monitor.
Connect the HDMI output from the PC to the HDMI input of the TV.
Check your TV and see if you have it hooked up to the primary HDMI input.
Even if you don't, you can switch inputs with your remote to get the correct one.

Yes you can also try unconnecting and re connecting TV first then Monitor second

Because no matter what the TV will be the Primary due to aspect ratio and resolution

He made a good point if it is a a Newer Tv might require some special finagaling to make it work but usualy Tv should be ready to go

Thousands of TV firmware updates are actually broadcast at certain times of day on what's known as an Engineering Channel, which might be one of the common channels when it's off air etc, but you'd need to check the book of instructions for model specific details...

Some newer ones, yes. Some even have a USB port for firmware flashing. But equipment such as the hugely popular range of Humax TV's/FTA tuner boxes, and others too, all rely on transmitted updates
