    Hi,

    I've been having a few problems trying to extend my desktop onto my new 40" Sony Bravio Tv, I have downloaded the latest drivers for my graphics card and updated it, it is a ati radeon 9800se edition, here is what I have done.

    I have tried all 3 cables including vga , hdmi , and s-video.

    VGA appears to be the best
    s-video is quite bad quality
    Hdmi is the problem I am having

    1) I have a 15 metre VGA cable but when I extend I get a shaking screen, enough to annoy me when i'm surfing the internet but not enought to watch a film or something like that off my pc.

    2) not even going to mention s-video starting now

    3)I have a dvi port on my graphics card so I got a dvi-hdmi adapter and a hdmi cable to attach to my tv, when I extend it is not displayed properly and only shows up on about 75% of the screen, I have tried all resolutions and played with the screen format on my tv remote, none of which seems to work. My question is simple, has any1 else done this and if so what was te fix?

    I have my desktop exteded from my 15" dell monitor to Samsung LE32r71 LCD... wasn't the easiet, but got there in the end. Used a 6m DVI --> HDMI cable, upgraded to latest drivers (nVidea 93.71, although this doesn't apply to you on ATI)
    The nVidea driver package has a control panel that lets you set seperate resolutions for both displays, Have the dell @ 1024x768 and TV @ 1080i
    Took alot of messing about with driver settings before settling on this.

    Use the TV manual to find the native resolution for your TV, try to manually set the DVI output of the graphics card to this... should work!

    Hi,

    I have indeed both resolutions set differently, pc monitor @ 1024 x 760 and tv at 1268 x 768 i think, but still no difference, I have also read the tv manual and tried it at the native settings but still no joy, the vga one extends no problem though, after 5 mins it starts going shaky on the screen but the hdmi cable just won't work at any resolution at it only displays on about 75% of the screen.

    A Radeon 9800SE "might" be not suitable for DVI-HDMI as only later generation cards came with some built in correction of problems associated with HDMI inputs.

    The native resolution of the TV is probably 1366x768 if it is not a FullHD (1920x1080) panel & that is what you need to set the resolution as (it must be a forced custom resolution as 1366x768 is not a normal computer resolution). In the graphics cards control panel there may be some over/underscan correction settings that you can also use.

    Alternatively try Powerstrip to set the resolution.

    Last but not least a higher quality VGA cable may offset the problems with using that.
