when using my monitor catalyst controller and crossfire works fine but when changing to the tv there are very few options in catalyst controller and all the crossfire things dissapear. Is it possible to use crossfire on the TV ...Do I need a driver?
You might have to set up the numbering system on the Tv/monitors. If the TV is #1 and the monitor is #2, reverse them. Also, you can try using the Clone monitor function where the TV and the monitor will have the exact same resolution and picture.
Also, you can use the tool GPU-z in order to determine if you are in CF mode or not. It is on or off, the monitors should not affect the crossfire setting. You may have lost the settings because the TV is considered "extended display" and not the system display.
I don't know how or if this relates to your setup at all, But I have a 40" Samsung LN40A63 LCD TV hooked up to my system.
In the video input configuration menu you can select different names for the various inputs. What's curious about this is that if I select the PC option for one of the inputs it actually changes how the TV interacts with the computer.
If I have it on any other setting the computer reads the TV as a generic Plug-n-Play monitor and CF loses most of it's options. With PC selected for the input title, Windows and CF read the model and serial No. of my TV. CF also has a much wider variety of options available, including options directly referring to my digital flat panel television.
This also fixes an issue with how the image is displayed on the screen. (Before setting the input to PC, about 14 pixels were cropped all around the screeen.)
I tried to duplicate the screen but catalyst told me the operation was not supported.
I tried the GPU-Z program which tells me that muti-GPU is enabled, when i start games on my monitor I get the cross-fire symbol in the top-right corner but not when i use the TV.
I did have the 14 pixel issue that I corrected manually, where can i find the video input configuration menu?
I also found that on the TV properties option instead of catalyst control centre its using inter(R) graphics and media control panel, whereas my monitor is using catalyst controller instead. It recognises everything about the TV but nothing in it about crossfire. I have only recently installed the PC and have not put on anything myself from intel.
In display adaptors I have 2 radeon 6900 series and one intel HD graphics family. When I uninstalled the HD graphics family with the TV as main and restarted, win7 put the intel driver back on and according to GPU-Z is using that when I am using the TV. I also get a message when starting up using catalyst controller that catalyst is not supported by the driver version of your enabled graphics adaptor.
I don't actually understand what is happening and why the intel driver is being used and not the radeon one. I tried disabling the intel HD graphics but then I lost the option to switch to the TV so I don't think the radeon ones can detect my plasma TV. Is there a way to override this and make it use the radeon ones?
Appreciate all the help so far, i find pc problem solving hard going.
Yes that was it, I had it plugged into the HDMI labelled plug rather than the odd looking one on the GPU... Thanks all!
However the screen horizontal and vertical positioning is slightly wrong. Unfortunately the aspect options on the TV are extremely limited, none are available in catalyst (other than over/underscan which didn't get it quite right) when using my TV either and two other programs for correcting this have all said that they are not compatible with the TV (or GPU). I have the resolution set to native: 1080p 1920x1080 60hz
Yes, I think there is a program called powerstrip that can let you do custom resolutions to fix what's going on. Sometimes changing the resolution to non-native can help as well. I'm sure someone has a better solution though.
