Monitor view weird , can't find drivers or monitor model here

Question

I just picked up my montior at a Bargain Center , it is a new monitor , but i cant find the model here on HP's site  ,  it says on the back tag  , TSS-25BG  , and i searched and can not find this model
My issue is that every website i go to the image is in the center and not filling the screen  , i tried Windows settings , but nothing i did changed anything , i tried adjusting the broswer settings (it look the same in Firefox , and Google Chrome)  , even on this site , everything is bunched into the middle of the screen    , in my device Manager , it just says Generic Plug and Play Monitor , so i thought maybe the driver needs to be installed , but as mentioned  , i can't find my model on this site   , any info would be appreciated
FRESH (today) installation of Windows 7 Ultimate 64 bit on brand new 1tb Sata HD  , Fresh Firefox , fresh  Google Chrome , ALL Windows Updates done today , and completely up to date  , i don't know if this will solve my issue , but i would like the correct drivers for the monitor anyway  , any idea's ??   ... Thanks ... Jim
EDIT:
I just ran Belarc Advisor to scan my PC for hardware and software , and it says my montitor is a HP model 2509  , S/N 3CQ1161S5  , which is not what the back label says (what i posted above) , so i am confused  , the next question is , what 2509 model is it  , i thought i saw several ??  , for HD montiors i only saw 2  , a  2509M  and a  2509P , they are both HD Value monitors , which mine is HD , but which one ??
EDIT2:
After reading all the info for the 2509 montiors , i have determined that mine is the 2509M , so i downloaded and installed the Driver and Manual for that ... it did not change the view , so i am now guessing this is a Windows 7 issue to do with wide screen monitors and how it shows images , so i will try the Microsoft forums and see if i find any answers

Hello @JimDirt,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I have read your post on how you are not able to get the view you want on your 2509m monitor, and I would be happy to assist you in this matter!
I am providing you with some steps you can try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
Step 6. Try a different cable connecting your monitor to your computer
If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.
