troubleshoot multiple screens

[ann_m_]

i upgraded to windows 7,connecting to my Samsung tv did work before with xp, now it doesnt work anymore... Any ideas? The computer understands there is a second screen but it doesnt get to the tv... can it be a driver? i have NVIDIA nForce MCP77MV Chipset and the driver is nvidia GE Force 8200M G

I've had troubles like this before. Try switching the TV to the 'primary monitor'.
