Chapter 6 Configuring HDTV 3 Click the Advanced button. 4 Click the Adapter tab. 5 Click List All Modes and locate the resolution. Problem: For 720p/1080i, we cannot find the resolution 1280x720 (720p) and 1920x1080 (1080i). Answer: You are probably using nView Clone or an nView Span display mode where HDTV is the secondary display. Note: When using nView Clone or an nView Span mode, the secondary display should not be set to a higher resolution than the primary. If, however, that is your current setting, you can solve the problem in one of three ways: • Make the HDTV be the primary display. • Assign a different display that can handle higher resolutions as the "primary". • Do not use the nView Clone or Span modes. Problem 1: Screen is shrunk. The screen shrink should only be horizontal. Answer: This is because 720p is 1280 pixels wide, but your desktop is only 1024 wide. Problem 2: The horizontal edges of the screen are cut. For example, we only see half of the Windows taskbar. Answer: This means that your HDTV has more than 18% overscan - therefore, some of the 768 lines are not visible. The solution is to use the Overscan shift slider on your HDTV display's NVIDIA Device Adjustment page.

______
Problem:
For 720p/1080i, we cannot find the resolution 1280x720 (720p) and
1920x1080 (1080i).
Answer
: You are probably using nView Clone or an nView Span display mode
where HDTV is the
secondary
display.
Note:
When using nView Clone or an nView Span mode, the secondary display
should not be set to a higher resolution than the primary. If, however, that is
your current setting, you can solve the problem in one of three ways:
Make the HDTV be the primary display.
Assign a different display that can handle higher resolutions as the “primary”.
Do not use the nView Clone or Span modes.

Problem 1
: Screen is shrunk. The screen shrink should only be horizontal.
Answer
: This is because 720p is 1280 pixels wide, but your desktop is only 1024 wide.
Problem 2
: The horizontal edges of the screen are cut. For example, we only see half
of the Windows taskbar.
Answer
: This means that your HDTV has more than 18% overscan — therefore, some
of the 768 lines are not visible. The solution is to use the
Overscan shift
slider on your
HDTV display’s NVIDIA Device Adjustment page.
