After days of trial and error, I think I have solved my overscan problem. I was hoping someone in this forum would give me the solution and save me hours of effort. But I will share my finding with the forum in hopes of giving others what I have discovered.
The key was finding and using a utility program included on the laptop - The Intel Graphics and Media Control Panel. There is an icon for this program in the system tray. I used this program to make settings for output to both the laptop screen and the High Def TV. The program Operating Mode must be set to Single Display because one needs different settings for the 2 displays. Clone Mode will not allow proper settings for the 2 devices in this case. In my case the TV automatically appeared in this program labeled the Digital Television TX-SR806 display.
Tray > Intel HD Graphics Icon > Right Click > Graphics Properties > Basic Mode (Gets one to this Control Panel)
Click the question mark bubble at the bottom of the window to display information as the cursor moves over setting names. I could not find a Users Manual for this program. Reading the information after my cursor moves, gave me clues on how to proceed.
Without the TV connected -
Select Multiple Displays in the Control Panel left column. Make sure...
Operating Mode = Single Display (Not Clone or Extended Display)
Primary Display = Built-In Display
Connect the TV using HDMI cable with TV input set to the laptop's HDMI input number. Do whatever is necessary to make the Control Panel visible on the TV screen -
Select Multiple Displays in the left column. Make sure...
Operation Mode = Single Display (Not Clone or Extended Display)
Primary Display = Digital Television
Select General Settings
Resolution = 1920x1080
Scaling = Customize Aspect Ratio
Horizontal Scaling = 70
Vertical Scaling = 70
Once the new settings are made, they can be saved in a custom Profile in the program's Advanced Mode. I have saved 2 profiles - 1 for the laptop screen and 1 for the HDTV. I start-up the laptop in the Profile for the laptop settings each session. When I want to view a movie, I switch the TV to the HDMI input connected to the laptop and the laptop will automatically switch to the HDTV Profile. The laptop screen goes blank and shows-up on the TV. What I would normally see on the laptop screen is now showing on the HDTV screen with no overscan (all 4 corners of the desktop are just visible). Viewing the HDTV screen, I start the Media Player software and watch the movie. When I finish the movie, I switch the TV input to another TV input and the laptop screen comes alive with what had just been showing on the HDTV. This switching of screen content from laptop to TV and back to laptop is all happening automatically without me touching the Intel Graphics and Media Control Panel. I guess the HDMI protocal is handling the necessary communication for where the content/picture should appear. After watching a movie, I make sure the computer display is automatically put back to the laptop screen.
These are the procedures and settings that worked for me. I am not an expert in this area. I have learned by trial and error. If I have not tried it, I do not know about it. Try these procedures/settings at your own risk. They may need to be changed to fit your situation. All I know is that this worked for me.
After making the new settings and connecting the TV to the laptop, I played a Blu-ray movie through the Lenovo PowerDVD 10 program and the picture was perfect. Somehow the new graphics settings solved my Blu-ray no-display problem. So, now both my problems (Overscan & No Blu-ray Picture on TV) are apparently solved. Case closed!!!

Are you sure your TV doesn't have a setting for that? My LG 42LE5400 LED HDTV has a setting in Menu / Picture / Aspect ratio select option "just scan".
My V570 automatically set res to 1920x1080. It slightly overstanned the LG. With the TV option above it corrected it perfectly.
