Video problem after I replaced laptop screen

Toshiba / Satellite l500-1dt
January 15, 2010 at 06:09:47
Specs: Windows 7
I replaced the LCD on a toshiba satellite L500,
it is a 15.6" screen but when i turned it on after
replacing the image on it wont fill the full of the
LCD. It looks like the computer thinks it is a
15.4" LCD it is displaying onto. I have
reinstalled video driver and there is no option
about dislay in the BIOS. Any suggestions
would greatly help....

You probably have the display resolution set wrong.

Toshiba satellite L500
"Native LCD Panel Resolution: 1366x768
16.7 million colours"

Apparently that's a widescreen 16 to 9 (~ 1.78 to 1) aspect ratio (the ratio of the width to the height of the image). If you had it set to a resolution that has a 4:3 aspect ratio (1.33 to 1) the image won't fill the screen.

"... have you tried right click desktop > properties > settings (tab) "

That's applicable for XP and Previous, but not for Windows 7.
For Windows 7 I assume it's the same as for Vista.

RIGHT click on a blank area of the main desktop screen.
Choose Personalize.
Choose Display Settings.
Change the Resolution to 1366x768, and the number of colors to Highest it it isn't already set to that.
Click on OK.

Your video drivers have to be installed properly, and your proper monitor driver has to be installed in order for you to be able to select 1366x768

If you can't select 1366x768, let me know and I'll provide further info. If your video drivers are installed properly, you need to load a monitor driver that suits your widescreen display.

Yeah im unable to select a 1366 x 768 resolution, i can select a
1280 x 800 one.
I understand that if the resolution settings are wrong it wont fit on
the screen properly but my problem is that no resolution setting I
am able to select will allow it to fit properly. I appreciate the

I'm assuming that you get the Display Settings window when you do this, the same as I do in Vista:

RIGHT click on a blank area of the main desktop screen.
Choose Personalize.
Choose Display Settings.

If you do, you will see a line that has which monitor driver is being used for your video adapter stated.

E.g. On my computer that has Vista, that says Generic PNP Monitor on ATI All-in-Wonder HD.
If your video drivers are installed properly, your line should state ..... on Intel something.
If that doesn't say Intel something, then your video drivers are not installed properly, or something else isn't installed.

I see that if the video drivers are installed properly, if the monitor driver is Generic PNP Monitor, I don't have all the resolutions listed that the video drivers for my ATI All-in-Wonder HD card support, because Windows doesn't know what my actual monitor model is - there are only a few, and they're mostly standard 4:3 aspect ratio resolutions. E.g. 800 x 600, 1024 x 768, etc.

"i can select a 1280 x 800 one."

That resolution has a 16:10 aspect ratio (1.6 to 1) - your display has a 16:9 aspect ratio (1.78 to 1).

Do you see Generic PNP Monitor there?
Do you see .......on Intel something there?

Does your computer still have the orginal Toshiba software installation on it, or have you re-loaded Windows 7?

yeah the display adaptor is a "Mobile Intel(R) 4 Series Express
Chipset Family".
But the monitor adaptor is "Generic PnP Monitor".
No win 7 has not been reloaded on it, but when i go to update
the monitor driver is says that windows has determined that the
driver is up to date.

"when i go to update

That's because it's looking for updates for "Generic PNP Monitor", and of course there is no updated drivers for that.

Assuming you were able to get the computer to use 1366x768 before, if the original Toshiba software installation is still present, you should be able to select the proper monitor drivers, because they should be there in the original Toshiba installation.

RIGHT click on a blank area of the main desktop screen.
Display Settings
Advanced Settings
Monitor tab
Driver tab
Update Driver
Browse my computer...
Let me pick fron a list ...
Click on the small box beside Show compatible hardware to remove the checkmark
Scroll down to Toshiba
Your proper monitor drivers should be in that list somewhere.

Since I have no additional Toshiba monitor drivers installed, only the default ones, I can only tell you it's NOT
a Toshiba 15 Multimedia display,
a Toshiba CRTxxxx display
a DA15xx
a DP566M
a DRxxxMx
a Toshiba internal 1024x600, 1024x768, or 800x600 Panel
(20 listings in total - if you have more than 20, the proper drivers are there somewhere, assuming that's the same as in Vista)
Toshiba internal 1366x768 Panel ?
Toshiba widescreen something?

once you have picked one

Select Open, OK.
If more than one model is listed, pick the one you have.
Select Next, Close, Close, OK.
The drivers are not actually loaded until you get back to the Display Settings window and click on OK.

Go to Display Settings again - you should have the resolution listed you want to use.

If not, try rebooting, then going there.

If none of the ones you try get you 1366x768 , you could try asking someone who may be able to dig up what the proper drivers should be listed as.

There a small possibility something about your video drivers is corrupted.

You didn't supply all of the model number.
See the label that's on the outside of the case, probably on the bottom, for the full model number.

Click on the Downloads tab here.
Laptops - Satellite - L500-STxxxx

e.g. for L500-ST2521

Set operating system to Windows 7 32 or 64 bit, whichever applies.
Change All Categories to Display
Download and load both results.

"my full model no. is satellite L500-1DT "

Oops - sorry - I see that's in your info at the top of the first post.
You would need to look on a site for Ireland or Europe or UK.

I suggested loading both display drivers because if something about them is corrupted they may not be able to find the proper monitor driver.

It's a mystery to me where the specific monitor driver for a laptop display comes from. I've never seen a monitor driver for a laptop display listed in the downloads for a laptop model. Obviously it should already be set right if the laptop has all it's orginal software installed, if the Generic PNP drivers are not appropriate, which they usually aren't for a modern widescreen display, but for some reason that's not happening in your case.
It's relatively easy to find specific drivers for an external monitor if one isn't installed automatically.

If the proper *.inf file for the specific monitor is already on your computer somewhere, then you should be able to find it, by searching for *.inf files that contain the text 1366x768 or 1366 x 768, and that also contain Toshiba something when you examine them.
That's easy to do in XP and previous, you simply use Advanced Search, but apparently it isn't in Vista. It's search engine is not as straight forward to use, and it seems you can't search for a file named X and also filter for it also having Y within it's contents, in Advanced Search.
I searched on the web and found a free program that is supposed to make that easy, for Vista.
I don't know if the search engine situation is the same in Windows 7, but Vista and Windows 7 have many things in common, and I don't know if the prgram will work in Windows 7.
also see
which may or may not apply to Windows 7

*.inf files are normally hidden. If the search finds none, you need to change search settings to search for hidden and system files, and/or you may need to change a setting in Folder Options to allow file extensions and hidden and system files to be displayed, and therefore to be found when searching.
Control Panel - Folder Options - View.
if you use the built in search engine.
Control Panel - Folder Options - Search.

Another person I have answered recently and currently had the proper resolution become available after he re-installed the drivers for the mboard's main chipset, as well as the display drivers. You could try that too. You don't need to un-install prevuiosly installed drivers for that first, unless, possibly, they're NVidia drivers. In your case you probably have an Intel main chipset - get the drivers from the Intel web site - make sure you get ones for a laptop, not a desktop, chipset.
