Video card output to TV and Monitor

[antihero]

Just a quickie.....

My graphics card is connected to my monitor via DVI with the HDMI output unused atm. Just wondering if that as well as it being connected to the monitor via DVI can I also connect the HDMI to my TV as well?

thanks

You can try

Some cards will only allow to use one at a time (cheaper ones), others will allow you to use both. You can then choose to clone the display or have a desktop that spreads across both displays

Be carefull and check out your graghics card for connection problems. I nearly went insane trying to connect a samsung tv that i have used as a monitor via vga without problems to the hdmi slot on the card in this spec. http://h20000.www2.hp.com/bizsuppor...portFAQ&prodSeriesId=3644723&prodTypeId=12454

Turns out people all aver the planet have been going mental trying to get this connection to work. I found it by chance, completely confused, and pi44ed off. I swapped the card form another dead comp and BLISS, it all worked, two monitors again

it's an old ATI Radeon HD 4600...to be honest, it's only so i can pipe online HD content to the TV, so it'll either be TV or monitor, not both at once.

just to update (my 10m HDMI lead arrived this morning!)...

..it works fine. As my pc is now doubling up as a HTPC, I only need to use one display at a time, but watching youtube content in full HD at 42" is sweet

I have a Tv connected to a PC by HDMI and have to use scaling adjustment in the adaptor control panel to stop the output being larger than the TV screen. So if your TV picture size and monitor don't match it can be adjusted.

There's normally a setting in the menu to disable TV overscan to avoid this (assuming the panel is new). What model is it?

One thing you sometimes have to be careful of is getting the TV into the correct mode. If you are seeing compressed blacks and saturated whites, you may need to get your TV into RGB (or PC) mode. This is where it takes the full 0-255 as black to white rather than the TV standard of 16-239 being black to white...

The TV is run off the AV amplifier which does all the video input switching and decodes the sound. Obviously the PC is on the PC input on the amp but it probably just does a straight pass through.
As I'm not using an input on the TV for a particular source any adjustment to the TV would affect everything so the scaling in the adaptor settings was an easy fix.

Ahh.. OK

I found I just had to right click on desktop>screen resolution and just had to select output 1 or 2 as it had already selected the correct output resolution for the TV itself (it does also allow to output same resolution to both, but as my monitor is 2048x1152 it looks daft)

I had to do a bit of faffing at this point. I found I needed to install a separate driver (Realtek HD) but when this was selected via the volume mixer the test sound would play on the TV, but nothing else and I found I had to diasble the VIA HD drivers first. Mine also passes through a DTS AV amplifier.
