I have a HP2311x wide screen LCD attached to a HP Pavillion laptop running Windows 7 and has a AMD g6-3420M APU with Radeon HD Graphics. When I set up the monitors in the extended view (and the HP2311x LCD as my primary monitor) the recommended resolution for the HP2311x is 1920 x 1080, however when selected this is significantly larger than the screen (i.e. can't see teh task bar).
I have a second HP2311x hooked up to a Toshiba Satellite E105 laptop and it works with the 1920 x 1080 resolution just fine. I've been comparing the advanced settings between the two laptops to see if anything obvious is different for the tow HP2311x, however the only thing I see so far is that the HP laptop wants the refresh rate to be 59 Hz, versus 60Hz on teh Toshiba. Both monitors/laptops are set to Smaller - 100% (default) under the Windows Display settings.
Any suggestions on what to do?

I know you mentioned comparing the settings, but make sure your Control Panel\Appearance and Personalization\Display settings are the same or decrease the size to fit - I have this similar issue with my Samsung LED TV - If I have my display set to 120% I loose the task bar and side panels - once I set the display size to 100% all is good.
EDIT: Oh I didn't see that you are already using 100% display settings - doh! Maybe try upgrading/updating the graphics card and display driver if available. I know my NVIDIA.com drivers I downloaded helped lots with other issues I was having, it may help updating your drivers if there are any...

Thanks for the suggestion, however I'm unsure of how to update the drivers and upgrading/updating the graphics card sounds like something I shouldn't need to do to get a HP laptop less than a year old to work with a HP monitor of the same age? I've played around with the AMD Vision Engine Control Center and Windows Screen Resolution settings and can scale the HP 2311 monitor to 10% underscan when it is set at it's recommended resolution of 1920 x 1080, however the screen sharpness is like I'm looking through a coke bottle. I also went into the Device Propoerties for the HP 2311 through Control Panel and it does not seem to let me select "Update Driver" under the Hardware Properties.
Does anyone from HP read this forum that can help solve this HP product issue?

Ignore my plea for help. I fixed the issue in the AMD Vision Engine as it was the default pixel format that was the issue, set to "YCbCr 4:4:4 Pixel Format". When I randomly changed it to "RGB 4:4:4 Pixel Format PC Standard (Full RGB)" it works for tehfull 1920 x 1080 resolution on the HP 2311 monitor.

My HP laptop has a AMD A6 processor (rather than an intel). The AMD Vision Engine Control Center provides access to all the desktop and display settings, beyond the basic resolution settings that Windows Control Panel/Appearance and Personalization/Display provides. On my HP laptop if you right click on the desktop the first menu item is "AMD Vision Engine". Hopefully your laptop has this or something similar to adjust the desktop and external display settings as this was easy, once I found my way to this control center. I randomly changed the default pixel format (nothing more) with the external HP monitor connected and it then allowed the external monitor's default resolution (1920 x 1080). I didn't have this issue when connecting the same external HP monitror to an older Toshiba laptop, which seems silly when HP and HP aren't plug in and play. Good luck.
