Missing screen resolution

I have a Dell D610 laptop with a ATI Radeon Mobility X300 video card.
But I can' get XP to set 1142x864 resulution with this card.
I can select 1024x768, 1280x1024 and 1400x1050, but not 1152x864.

The card is supposed to support this resolution (all docs state that)
and in registry 1152x864 is also on the lists of resolutions I found

So why can't I select it for monitor 1 (the laptop LCD)?
(it is on the list for monitor 2, the external VGA connector)

Any hacks to add it (I did that for a Nvidia card when it was missing,
they have possibility to add ANY resolution in the control panel .-)

Is there anything I can do with the INF-file for the card or monitor?
 
Are you sure that for the colour depth you want that resolution is
supported? If so, then the driver is wrong. Update i because in the inf file
is the way that displays the resolution
 
It might be that the display's driver is a generic one. I'm pretty sure that
it should be already installed, but it might not be. Go to Display Properties
-> Settings and see if it has your laptop's monitor name and then your ATI
adapter's name under the Display: label. If it does, then it isn't your
driver. If it is, then dig out your disk and install the driver.
 
Hi Lars,

Although the video card can support that resolution, it sounds as though
your laptop display *will not*. Although LCD displays are capable of
running at more than one resolution, most all have *one* they are truly
"comfortable at".
You haven't had the laptop display running at that resolution before, have
you??

Have tried all color depths (16 and 32 that is)
Also tried updating to the latest driver I found.
This is a Dell laptop with it own driver for the ATI X300
(couldn't download it from ATI for some reason...)

Yepm that is 1400x1050 for this one, but the ATI X300 can scale the
display (if I turn this off I get a black border round at lower res),
and the X300 does support 1152x864. So I see no reason it should not
be able to scale that one up to 1400x1050 as well (1152x864 doesn't
appear if I turn of "scale to fit" either, and that SHOULD work).

Nope, have used 1024x768, but need a bit higher (but 1280x1024 is to
small)

What are you trying to do ? The native resolution on the LCD is always the
best choice, for picture sharpness and readability.

If by 'too small', you mean somethng like the icons on the desktop are too
small, increase them in size.

'Display Properties' -> 'Appearance' tab -> 'Advanced' button. You can use
this to change the sizes of the individual windows elements w/o reducing
the screen resolution, and ultimately lowering the picture quality. Use the
drop-down box to pick the elements you want to change.

Font size to small, pictures on web pages to small (those can not be
size by DPI setting, and many programs look terrible if you change DPI
settings). I have two 1280x1024 LCDs (home and work), and they both
look OK with both 1024x768 and 1152x864. And my laptop with a native
res of 1400x1050 look very good at 1024x768, but the display (15") is
way to small to run 1280x1024 so I'd like to use 1152x768 on it.

I know it is possible (I have read about linux users with a Dell D610
that use 1152x768, it's one of the default there) so I can't just see
why it is not available from XP (it's available on the external VGA)

Bad font display issues is a common side-effect of changing the DPI, but
that is not what I was talking about.

Thru the Display Properties you can change all of sizes of each element
like Menu Font & Size, Titlebar Size & Font/Size, desktop Icon size/font
size, etc.

Most programs allow you to change the font/size as well.

Common knowledge is the best picture on the LCD screen will always be
achieved at the panel's native resolution.

You can surely adjust everything to take advantage of a 1400 x 1050
resolution of the panel, w/o having it downsample to some oddball setting.

There's your answer. That specific resolution is supported only for an
*external* monitor. Do you have one attached?

Yep, but many programs then look terrible (not written to support
that). And the LCDs I use display "non-optimal" res very well.
 
Display Properties, Settings, Advanced, Adapter, List all Modes, pick
the resolution, OK apply. If it works, fine, if not, you get to keep
both pieces. (A poweroff may force it back)
