Screen Res not using Full Monitor Display

[gavinjb]

Hi,

I am trying to connect my Sony Laptop to a ViewSonic VX2260 Monitor, I have the latest ATI Drivers installed for the Graphics card, but when I set the res to the recommended for the monitor (1920x1080) I get a black border round the screen which is unusable, I know this screen res works in Windows with no problems.

I am connecting to the Monitor with an HDMI cable, but if I use the VGA cable the screen res fills the whole screen, I am trying to use HDMI as when I use VGA I get a flickering across the screen which I think is from the poor quality VGA cable supplied.

I have also noticed that the Monitor is labelled as unknown so I thought at first this might be what was causing the problem, but as it shows as this with both HDMI and VGA I could be wrong (my understanding of xorg is very limited)

I have even compared the xorg.conf files form when connected with VGA and HDMI but no changes seem to have been made to the config file.

I did find something by googling the net about finding info using xresprobe but when I run this all I get back is

Driver must be specified.

Can anyone help?

Thanks,



Gavin,
