BenQ FP731 colour depth problem

I am running the latest drivers for my onboard NVidia GPU and BenQ FP731
LCD screen, however I cannot run at 32-bit colour at 1280x1024. To get that
colour depth I have to drop to the non-native 1024x768 resolution. Are there
any solutions out there??

First check the amount of video memory allocated to the display
in the bios setup... increase that if necessary.

Check the BenQ monitor's INF file to confirm that it lists the
desired mode. If it does, try changing the driver in display
properties, if already appearing set correctly then try different
monitor like Plug-n-play then set back to the BenQ.

If you're using Detonator 5x.x or 6x.x series driver you might
try 4x.x series.
 
It sounds like your on-board graphics chip, which are always underpowered
but cheap, does not have the capability of running that resolution at that
color depth. You would need to get an AGP video card for your system and
give up the weak on-board graphics. IF your motherboard even HAS an AGP
slot. Better check first.

I haven't seen an nVidia chipset board yet that doesn't have an AGP slot.

Most LCD Monitors are not true 32 Bit Colours, I know mine in not..

Not having an LCD monitor myself I have to ask: can you see the
difference between 16bit and 32bit colour on an LCD monitor? I can't
pick it on a CRT monitor.

Any semi-modern integrated graphics can do that resolution and
color depth fine. In fact there is no issue of underpowered nor
cheap involved, it's all a matter of a configuration problem that
could occur with any display adapter, OR a bios setting for
amount of memory allocated to the video (frame buffer).
 
I have a BenQ 737s, but can't see the difference between 16bit and 32bit my
LCD monitor!!
May be my eyes something wrong!!

There is practically no difference at all between 24 bit and 32 bit. The
step from 16 bit to 24 bit is still significant, but you are extremely
unlikely to notice it when viewing screens made up of only a relatively
small number of different colours in solid blocks. The difference should
be more noticeable when looking at photos which have a wide range of
colours in them.
 
Oh, you can notice it!! Especially in gradients.

I put an AGP card in and its going beaut. Color depth is much, much better.

Thanks for the advice.

If you're happy, fine, but there is no need for an AGP card
merely to get 24 - 32 bpp @ 1280x 1024. Even an old 8MB
integrated video can do that.
