New VGA Cable, Laptop Monitor No Longer in WS

Specs: Windows 7 64bit, TBD
I use my Vizio 37" HDTV (LCD, 720p) as a laptop monitor since my laptop screen is busted. Today I bought a VGA cable extender to allow me to sit further away than 3 feet so my eyes don't melt. But I boot up the computer and suddenly the resolution is out of whack. I tried to adjust resolution and it won't allow for the 1366 x 728 resolution I was getting. Now it's in fullscreen.
I took away the VGA cable extender and restarted, no change. I did a system restore, no change. Updated the drivers, no updates available; performed a check disk; and a spyware scan.

Not sure what else to try. It was fine literally 2 hours ago. What's going on? How do I get it back to the widescreen aspect ratio?

Did you try to manually reset the resolution after removing the cable extension?

If the wide screen resolutions are not available then you need to get the computer to identify the display again. Install it if necessary in the graphics settings.

I don't recall having to install any display or select it as a specific type, but it I did press "identify" and "detect" making sure the "projector" was selected (projector meaning the tv).

Do you have another choice besides using "projector"? Should be a choice for a second display with two choices. First would extend the primary display. Choose the second one, which should be something like make that the primary display.

For some reason the two choices under display are Generic Pnp Monitor and Generic Non-Pnp Monitor...

When you identified the projector was it identified as the primary or secondary display? How about now when set as a monitor?

It's the secondary display. The primary is the laptop screen itself, it's always been like that, but for some reason, both are listed as Generic displays now...

Try making the TV the primary display.

I believe I have already. But just in case, how does one do that?

Unfortunately when things worked as you wanted you probably had no reason to actually examine these settings so it is hard to determine what settings to use.

What is the make and model of your computer.

Below is a link to the ATI site. Download the latest catalyst drivers 11.4 dated 4/27/2011.

You need to also download the help files and read them. ATI software is not easy to use IMO but it should work. Read the release notes that are linked on that same page. Check to see if it is recommended that you uninstall any earlier versions.

Danke.

Computer doesn't recognize the displays but at least the resolution options have changed. Now I have a list of every major resolution so I'm good. Thank you.

EDIT: Except it won't let me do the recommended 60Hz refresh rate so there is a weird flicker. I tried changing it in advance settings. It lists 59 and 60. I choose 60, hit apply, it asks me if i wish to keep the settings, I say yes. And nothing changes. Check it again, says 59 again. :(

You shouldn't get any flicker at 59Hz either. I have run into that same issue. I think it must be something to do with rounding off. I

I am running Windows 7. Windows 7 controls are somewhat different than WinXP. When I right click on the desktop I have a menus with screen resolution on it. Clicking shows the resolution and the monitor model. No refresh rate. If I click on advanced settings I then see the refresh rate but the monitor is listed there as default plug and play. Go figure.

What is the full model number of your Vizio?

I fixed it, I changed the resolution to one slightly closer to 16:9, even though the manual on the tv prefers 1366 x 768 which is actually 16:10 (8:5 I guess). Dropping it down automatically had the refresh rate at 60Hz which is the manual's preferred rate. Flickering stopped.
Viola.

So I think I'm good now. Thank you for your help.
For curiosity's sake, my vizio model is the VX37L.
