Experiencing pinkish hue on the right side of the screen, along with visible lines.  
Both the lines and pinkish color are localized the right side only.

Here's what I've tried:

1. Unplugged both ends of the DVI cable (and then plugged them back in too!)
2. Disconnected monitor power and reconnected
3. Rebooted computer
4. Checked monitor driver on computer- computer states it is up to date
5. Ran built-in diagnostics per manual (ftp://ftp.dell.com/Manuals/all-products/esuprt_electronics/esuprt_Display/dell-s2340m_User%27s%20Guide_en-us.pdf)
including disconnecting cabling. The pinkish color and lines are most prominent on the first (gray) screen.
6. Attempted to appease the monitor gods by encouraging my preschooler to do a silly dance (this did not work either)


Pertinent hardware/software:

NVIDIA GeForce 7100 video card
Compaq Presario SR5450F
Windows 7 SP1
using a DVI cable

Any other suggestions?  I gave my wife the monitor for Christmas this year.  I'd prefer the present worked as intended :)

thanks
