Windows 7 Extended Desktop issue with Samsung TV

by justkanishk / August 7, 2010 10:06 AM PDT

I have Windows 7 Enterprise installed on my Dell laptop. When I connect it to Samsung 46" LCD TV using VGA and press Fn+F8, my TV gives the error "Mode not supported". I have already tried playing with the settings in screen resolution and changing the resolution for TV & laptop separately.

However when I connect the same laptop to a Samsung 22" monitor, I can extend the display without any issues.

PC Details:
Dell Inspiron 6000 - 15"
Screen Resolution: 1680x1050
Intel Pentium R 1.66GHz/2 GB RAM
Display: ATI Mobility RADEON X300

TV Details:
Samsung LN46A750R

Can someone help in this regard?

Thanks for the reply. However, I am not sure if this will fix my problem. I have been using the same laptop with Windows XP with this TV using VGA connector since last 2 years (till 2 weeks ago when I upgraded to Windows 7). I have always been able to use the TV at 1920x1080 resolution by pressing Fn+f* in past. However, the error started coming with Windows 7. I have also installed all Windows 7 updates including the one for Samsung SyncMaster display.

That's a little more telling.

Microsoft does not supply all our machine's drivers. I read many post about all Windows 7 udpates but to fix this I bet we have to go get the drivers the old fashioned way. Hint? From the machine's makers.

Until then I think we are limited to 720p over HDMI if HDMI even works with Microsoft's drivers.

You wrote you have Windows 7 Enterprise! That's really great news as that includes support from Microsoft and the company that gave you this!

I envy you!
