Connecting a Sony KDL-19M4000 HDTV to a Sony Vaio PCG-V505BCP laptop

It took me some hours to figure out how to get a Sony Vaio PCG-V505BCP laptop running Windows XP Professional to work with a Sony KDL-19M4000 HDTV the way I wanted it to, so I'm posting these instructions in case they might help someone else.

The instructions haven't been completely walked through end to end yet—they are based on notes. So there may be some missing, unnecessary, and/or incorrect steps.

1. Turn both TV and PC off.
2. Hookup laptop docking station to TV using a VGA cable, not a DVI-D/HDMI cable per the note on page of the KDL-19M4000 Operating Instructions booklet: "Do not connect a PC to the TV's HDMI input. Use the PC IN (RGB IN) input instead when connecting a PC. Note that although the Sony document "How to Use Your Television as a Computer Monitor" appears to imply that the docking station can be hooked up to the TV using the docking station's DVI-D port and the TV's HDMI port, a Sony technical support person told me that there would be no benefit in doing this since the signal from the laptop to the docking station is analog.
3. Turn on TV and set input to "PC" with Wide Mode set to Normal.
4. Turn on computer with laptop open. The operating system should recognize the TV as a plug and play monitor, but at best will only give a 1024 x 768 resolution which leaves a large border of unused screen space.
5. Download and install latest ATI® Mobility™ Radeon™ Graphics Controller Driver Update from Sony support site for PCG-V505BCP.
6. Download and install EnTech Powerstrip installer. I learned about this utility from the aforementioned Sony document "How to Use Your Television as a Computer Monitor".
7. Go to Windows Display properties > Settings tab.
8. Click on monitor number 1 box to highlight it.
9. Click Advanced button.
10. Click Displays tab.
11. Make sure both monitors are "on" with a green on/off icon instead of a red on/off icon.
12. Click target button for notebook LCD display to make it the primary monitor, which should automatically set the external monitor as the secondary monitor.
13. (What steps did I take next? Click OK a couple fo times?)
14. Open Powerstrip > Display Profiles > Configure
15. Below "X" to close window, click down arrow to change display to "2. Mobility Radeon 2".
16. Click Advanced Timing Options button.
17. Make sure "2. Mobility Radeon 2" is shown on left side of window.
18. Click "Custom Resolutions".
19. Click "E-EDID".
20. Highlight the second resolution, 1440 x 900, then click "Add new resolution". (For some reason the 1280 x 768 resolution doesn't work for me.)
21. Click button to restart computer.
22. Go to Windows Display properties > Settings tab.
23. Click on monitor number 2 box to highlight it.
24. Click checkmark to extend desktop.
25. Click OK to close Windows Display properties.
26. Open Windows Display properties again.
27. Click on monitor number 2 box to highlight it.
28. Change resolution to 1440 x 900.
29. OK to close.
30. Change monitor 2 (TV) to primary monitor.
31. Drag monitor 2 (now the laptop LCD) to be diagonally to the right and below monitor 1, to minimize accidentally losing mouse pointer on laptop monitor while laptop is closed.
