Connecting PC to TV via HDMI cable

coley2123 140 22 July 5, 2011 at 06:07 AM
Previously used our Toshiba HD tv for computer monitor (video only, sound via separate speakers), worked just fine.

Looking to connect the computer to the TV using HDMI cable - after connecting the cable, have no sound or picture (changed TV input to HDMI).

Disconnected the computer monitor cable (sorry forget the name of it, the one that screws into the tower and monitor) and the speakers. Rebooted with HDMI cable connected and nothing. Reconnected the "monitor cable" and got picture back using the PC setting on the TV (changed from HDMI to PC).

When I looked at my sound options in the control panel, the HDMI is there but says something about "not connnected" or "not plugged in"

Have no option to make HDMI default or "turn it on" ...

Simply connect the HDMI cable from your PC to the TV, once the video from the computer is on the TV, go into the TV settings menu, look under audio settings, for an option to enable audio over HDMI. If that doesn't solve the issue then you need to select the TV as the default audio output device on your computer under "playback devices" which should be listed as a selection if you right click on the speaker icon in your system tray.

I plugged in the HDMI cable, unplugged the monitor cable (VGA plug?) and unplugged the speakers. Rebooted and never got a picture on the TV. I changed the TV input from PC (which used the VGA plug) to HDMI and was left with no sound, no picture. I had to switch back to the VGA and speakers, reboot and change TV back to PC input in order to try to trouble shoot - that's when I saw the "not plugged in" or "not connected" (sorry I can't remember the exact phrase and am at work now). There was no option to make the change to the HDMI in the sound properties from the control panel. So basically I'm getting neither sound nor picture from the HDMI cable. I did test the HDMI cord and the TV using my HD cable box and the picture came thru along with sound. Any ideas?

Go into video card settings and enable HDMI out. The ATI 4650 should also pass audio. You will most likely have to enable that too.

These two steps.

Also, make sure there's no "enable HDMI" setting in your BIOS.

so it was a really rough night after an incredibly long day - couldn't even remember how to get into video card settings to make the changes. Anyway, never did see the "enable HDMI out" option and my system says the HDMI is "not plugged in"

Where's the best site to do the video card driver update? Assume (ok, wrong word) that Radeon site would be best but some swear by other driver update sites. What's the best way to see if mine is the most up to date version?

Any help is very much appreciated as I can't get video or audio using the HDMI cable (I am changing the TV from PC to HDMI input and have tested both the cable and the tv).

on the BIOS - it's been literally over 10 years since I've even touched anything in any computer BIOS... is there an easy 101 (or steps) that I can follow to check that setting? Don't want to screw anything up in there...

No, don't go to any driver update site, just go directly to AMD website
http://support.amd.com/us/gpudown...index.aspx

Make sure you download the full suite with the Catalyst control center and the driver, not just the driver by itself

I'm right 97% of the time. Who cares about the other 4%

Ok, had a real detailed post ready to submit and since I went downstairs to get the info from the other computer, it must have timed out... so here goes again (sorry if I miss something, had it all there, doing again):

Downloaded about 104 MS updates (yep, a computer that was barely used but I need to start using it as HTPC and have a ton of videos to convert so I want them to run on that machine and not clog up the main PC). Unfortunately, I have been very short on time this week and just selected "download all updates" without weeding out Norton and Office trials, but that should not be affecting the HDMI issue - I'll spend more time deleting them later).

I downloaded the Catalyst suite (including drivers and control center). Still do not have the option to "enable HD video or audio". Is there a "cliff's notes" for the control center or am I perhaps missing something?

Someone mentioned checking the BIOS - anyone willing to walk me through that process? It's been too many years since I've done that one and don't want to screw up the computer.

Here is some of the info from the system I'm trying to get HDMI connection operable:

from Control Panel / Personalization / Display Settings:
Monitor: Generic Non-PnP monitor on ATI Radeon HD 4600 Series
1024 x 726 32 bit Color
Properties of Adapter: Location: Bus2, device 0, function 0
drive date: 5/24/11
version: 8.861.0.0

Sound:
1. Realtek HDMI Output / 2 ATI HDMI Audio / Not Plugged In
2. Realtek HDMI Output / ATI HDMI Audio / Not Plugged In
3. Speakers / Realtek High Definition Audio / Working
4. Realtek Digital Output / Realtek High Definition Audio / Working

Not able to get sound or video using HDMI cable on Toshiba 19hlv87 HD LCD TV (using HDMI input TV setting)

Am able to get video using VGA cable on above listed TV (using PC setting)
Am able to get sound using external speakers

Realizing the VGA and external speakers are not HD output, how do I "enable" video and sound HD on the card?

Any help is really appreciated since my patience is wearing thin... I did test the HDMI cable again on the HD cable box with success, the only thing I have not done is drug the computer out to the main TV in the kitchen to connect it there

for audio : in the control panel click on sound ; select audio tab and change default device to Realtek HD
for video: usually it's works as is but you can try to enable dual monitor

I took the HDMI cable off the computer/tv and connected to Kitchen HD cable box & Tv, worked fine. Bought another new cable, tried that and now, I finally call UNCLE!

I just took the HDMI cable off and connected the single out from computer to red, white on TV (analog?)... have sound and am using picture from the VGA cable.

I can't fight with this thing anymore!

If anyone has any other ideas, I may try them but not until tomorrow. Thanks to all that offered suggestions... almost a week later, and I give up.
