HP W1907 - 1440x900 not available

HP Pavilion a6655f Desktop PC

HP W1907 19-inch Widescreen Flat Panel LCD Monitor 

OS: Windows 7 64-bit

Problem:  I'm unable to set the native resolution of my monitor to 1440x900.  The monitor tries to auto adjust to that resolution, but it always gets set to a non-standard widescreen resolution, which results in poor blurry image.

In the display settings it doesn't list 1440x900 as an option, not even if I go into advance and tell it to list all unsupported.

I've tried numerious Nvidia driver updates and downloading the latest w1907 monitor driver and I'm still not able to set it to the native resolution.

Before going to Windows 7, I even did a factory restore from the recovery drive to stock factory Vista and it still did the same thing even straight from the factory reset.

Is the monitor defective?  I hooked another 27 inch monitor up to it and it works fine and shows 1440x900 in the list, but it's almost like the EDID is messed up on the 1907.

Any ideas on what else I can try?

i have the exact same issue, it appeared when i installed new drivers upon installation of a new graphics card. I have spent over 6 hours talking with technicians at nvidia troubleshooting, and they suggested, after analysing details of the monitor through a monitor asset manager that there is a corruption in the EDID. I currently have no solution.

Edit: I have spent 2-3 more hours trawling the internet looking for people with the same issue in other forums, i have found other exactly the same and very similar problems with this model of monitor in 10-15 different cases. in all cases there was no solutions provided and they date back as far as 2010. doubt we will find any solution without help from HP directly. At the moment i have been forced to accept a lower quality res of 1280x800 in correct aspect, or a stretched (vertically) 1360x768 as the most usable resolutions in the mean time, or 1600x900 stretched (horzontally) with a bit of the right side of the screen cut off... not really great imo. the issue appears to be independant of your computer specs and i have seen people with problems for both notebooks and desktops.

Hi,

Download the latest driver file list here under Windows 7 HP w1907. Now use 7-ZIP (freebie tool) to unzip the file. When you look into the zip folder you will see a files folder. Now go into Device Manager and find Monitors. Uninstall the existing driver. Now select update software then browse my computer and go to the files folder for the update.  Be sure that that you have admin authority. 

Once you have the new driver installed then go back and see if your can change the monitor's resolution to 1440x900.

i followed your steps one by one, then once i had uninstalled the generic pnp monitor driver, the monitor icon disappeared from the device manager list. i tried scan for hardware changes, and it reappered and the monitor option appeared, saying generic non-pnp monitor (oddly). i right clicked, went to driver, install new driver then browsed to my extracted folder. it came up saying "windows has determined the driver software for your device is up to date - generic non-pnp monitor" checked Nvidia Control panel... no change, blurry custom 1440x900 60hz

i repeated the process again, uninstalling and browsing the new install, and then selected "let me pick from a list of device drivers on this computer" then "have disk" and selected the driver from zip location. the monitor now appears in the device manager as HP w1907 wide LCD Monitor. checked NVidia Control Panel again. no change...

i attempted reinstalling my nvidia drivers in safe mode, now the device manager was confirming the drivers for the monitor as being that of hp w1907 instead of generic non-pnp monitor. again, no change, still no 1440x900 option in ~Nvidia control panel, and custom resolution 1440x900 60hz is blurrey.

Edit: i also wanted to note that i had been using the same monitor, with a older graphics card, NVidia Geforce 9600 GT up until yesterday, with a perfect 1440x900 resolution created custom in nvidia control panel. I had seen this same issue crop up before when installing new nvidia driver updates. In the past after installing driver, performing a system restore to before the update cured the problem, and enabled perfect 1440x900 resolutions. this however is not a possibility, as i had to reinstall drivers for my new GPU.

Hi,

Try a monitor reset by unpluging the monitor (power and video) and then hold down the power button for 60 seconds.

Try the existing monitor and cable on another PC to eliminate those components as issues.  Additionally, try another monitor and cable on your PC to ensure that the PC is in good working order.

Hi,

Try a friend with a PC or the local PC repair shop.

New VGA cable fixed my issue and be sure to unplug the power to the monitor so that it power cycles.

i have tried all the proposed methods to fix this issue. and still have no solution. i have tested the monitor on another computer with the same vga cable, and no issue was found on another machine. the nvidia support team suggested a problem with the EDID, is there anything to do with this that could be affected by video driver installation?
