I have AMD Phenom X4 desktop running Vista 64 bit with 4GB Ram.
The Graphics Card is ATI Radeon HD 3200 with 780G chipset.
The monitor is ASUS 23.6" HD ready monitor with HDMI input.
The Card also has HDMI output but when i connect the monitor with HDMI cable the resolution suffers, images are blurred & the screen size reduces. I have black borders on all 4 sides. The only good thing is color intensity increases.
The driver s/w version is 8.531.0.0
The monitor works well in VGA mode & tested it with other HDMI inputs - it works well there.
Just the HDMI output from PC has problems

Any suggestions as to how i can get a true HDMI video & full screen?
Regards
