I have an Nvidia sa6600 for a video card, and it says right on it that it will do 720p and 1080i. When i go into the settings for the card and try to change the res. it says that the new resolution has taken effect, and to keep it click ok. But nothing changes, its still at 1024x768.
It also has an option to create custom resolutions. So i tried it this way as well, and the same thing happens.
On a side note, when i am in the display settings menu it sees my tv as a plug and play monitor. But in the nvidia display settings, it says my tv model number.
Thanks in advance.
