How to change resolution on Vista when it keeps booting to an unsupported resolution?

How to change resolution on Vista when it keeps booting to an unsupported resolution?

I have a Vista machine that used to be hooked up to a widescreen monitor, I moved and no longer have the monitor and planned to just hook it up to my widescreen TV's VGA input jack. I can see the initial DOS-type boot screen, and see the "Windows is about to boot" screen, but everything goes black and my TV displays an "unsupported video signal" message right before it would normally show me the Vista circle logo and have me select a user to log in with.

"Instead of safe mode boot to ""Low Resolution"" mode. It should be a few menu options below Safe Mode in that list.

Alternatively you can open msconfig from a command line. Navigate to the Boot tab, and put a check in the Base Video box from safe mode and reboot.

Edit: To answer your second question about detection. A monitor identifies itself to a computer, along with its specifications and native resolution over something called an EDID. The EDID resides on a ROM chip in the monitor and is a standard.

However OS vendors (such as Microsoft), video card manufacturers, and monitor manufacturers have typically done a mess of a job implementing it. This leads to shoddy support for advertisement of native res, etc, and when this happens, it causes problems like the one you are having."

"You can change the settings by blind typing if your video driver is behaving sanely.

I don't have a Vista box here to test on, but with XP you could type:

Windows key, c, d, d, enter, ctrl-tab, ctrl-tab, ctrl-tab, ctrl-tab, tab, shift-tab, down, down, enter.

This would reduce the screen resolution two steps. Use more ""down"" steps at the end to reduce it all the way to the minimum. Again, this is for XP, test on Vista (in Safe Mode) before trying this.

You could also boot into Safe Mode and change the video driver to ""VGA"" instead of whatever accelerated driver you're using. After you reboot into normal mode, reinstall the real driver and set whatever resolution you like."

In Windows Vista Home Basic 32bit, the easiest solution is just to go to Control Panel, and in the menu that the option to change the resolution is for you. Then, you need to go to More display modes of something simiral, search the tabs and find the option:Display all modes. When you press that button, a message will pop up saying that it will now show all modes and those that the monitor doesn't show properly. Ignore that and press OK. Then, when you try to change the resolution, it will let you choose more than 2. In my case it showed me 4 modes in 32bit and the maximum was 1600x1200. Hope it works!
