I have a setup at work where we have an HP computer that has dual monitors that runs through a KVM switch with another computer.  Both computers work fine and display resolutions can be adjusted with no problem.  However the HP has a separate HDMI cable running to a wall-mounted Sony TV so the office workers can view the larger display from a distance.  The 48" TV display is 'blown up' and if you try to adjust the resolution from the PC, the display settings are greyed out for the Sony.  The dual monitors on the desk can be adjusted, but the display for the TV shows as a very small box with resolution of 640*480.  The office personnel had this working before and then they went and moved their computer equipment around - which is when the problem began.  I am seeking support for the video card, but believe it might not fall under AMD support any longer.  The video driver is for an ATI Radeon HT5450.  The HP is running Windows 7, 64-bit.  Any suggestions would be greatly appreciated.
