Resolution changing an alert comes up telling me to change resolution to 1280x1024 how do i do that

This is not a GPO issue. The problem is that all Windows will attempt to set the new resolution and a fail-safe is that if you do not click the Keep Changes button after thirty seconds it switches back to the old settings. This ensures that if you set the resolution to a range the monitor or display adapter can't handle that you don't get 'stuck' with a blank screen.
Check that the display adapter in the Dell 780 can handle a resolution of 1280x1024 and that the monitor can also handle this resolution.

The easiest thing to try is change the screen resolution before connecting via HDMI. The process is a little different depending on what operating system you're using.
For Windows Vista/Windows 7: 1. Right click on your desktop and select "Screen Resolution" 2. Slide the bar to change the resolution to either 1024x768 or 1280x1024. 3. Click apply.
For Windows XP: 1. Right click on your desktop and select "Properties" 2. Click on the tab to the far right that says "Settings" 3. Under Screen Resolution, slide the bar to change the resolution to either 1024x768 or 1280x1024. 4. Click apply.
Either of these resolutions should at least give you picture when you reconnect with HDMI. Once you get a picture, repeat these steps and gradually move the slider higher to get a better resolution picture. If you receive the incompatible signal message again, just wait 15 seconds and the previous setting will be restored.
If this doesn't work, you may also have to adjust the screen refresh rate. From the same window that has the screen resolution adjustment bar, click the link or button that says "Advanced." The second tab, "Monitor," has a drop-down menu to adjust the screen refresh rate. Depending on your HDTV, the most common setting for this could be 60 Hz, 70 Hz, or 120 Hz. If none of those values work for you, you should check the manual that came with your TV to check what the proper resolution and refresh rate should be for your computer connection.

If you are in windows, right click on your desktop in a blank area. On the drop down box that shows, click on Screen resolution (For Windows 7), properties (For Windows XP), or personalize (For Windows Vista). From there navigate to any tab or menu option to change video settings, or screen resolution.

There should be a slider bar to change the resolution you have, slide it to the 1280x1024 option and click apply.

I have included a video to assist further if I did not explain well enough.

might try to change the refresh rate in the nvidia software also check the max resolution that your montior can handle.

on your desktop, click on the right click on the mouse. then go to properties, and screen settings. you can change the resolution from there. I would also recommend you to work on 1280x1024 as it fits best on the 17' you purchased.

Most probably your computer has a higher resolution or refresh frequencies set in Desktop Settings than supported by the monitor. It might be also, that you have previously installed a monitor driver for a different monitor model, and the computer is using resolutions and frequencies supported by that previous monitor, with which your new one can't cope.
The solution would be to boot the computer in safe mode (hit F8 key when the computer is starting, you can hit it a couple of times, until you see a menu; choose "Safe Mode" and hit Enter).
Go to Desktop Properties, change to Settings tab, and click "Advanced" button. In the new window choose "Monitor" tab and change the monitor to "Plug and Play monitor". Click OK to accept the settings and close both windows.
Now reboot the computer - it should start with a rather low resolution, but the picture should be visible. Now you have to go to your Desktop Settings again, Advanced tab, and move the resolution slider to position 1280x1024. Accept and enjoy.
If the computer still doesn't boot, go to safe mode again, go to Control Panel, System, Hardware, Device Manager, drill down to Monitors, and delete all the monitor devices installed. After a reboot, system should start up and find new hardware, and install Plug and Play monitor. Set the optimum resolution of 1280x1024 as written before.

The laptop is widescreen at a guess. The external monitor is not. You need to change your laptop screen resolution to be something like 1280x1024, or, you need to tell the monitor to be a display EXTENSION not a mirror. Right click the desktop, properties, then Settings. Click on the 2nd screen, and set its resolution to 1024x768 or 1280x1024. It's here you would tell it to extend not mirror too.

thanks,

Sounds like you have an LCD monitor. LCD monitors look best in their native resolution. Yours must be 1280x1024. You need to (assuming this is a Windows PC) right click on the desktop and choose Personalize, Display Settings (Vista) or Properties, Settings (XP or older). Set the slider to 1280x1024. It'll confirm the change and then the message should never reappear.

"60" refers to the refresh rate of the monitor in Hertz (Hz). It is set to match the resolution and should not be changed.
