configure my new LCD monitor

Hi,

How to replace an old monitor by a new one.

Old one:
Gateway CRT
Resolution 1152 x 864

New one:
Envision LCD
Resolution 1078 x 768

They have different scan frequencis.

Since the old monitor is not working, and the new one doesn't accept the current configuration, how do I configure these parameters by telnet?

My os is RH7.1.

it should still be able to boot to a command prompt with no problems, in redhat you can use Xconfigurator or xf86config to set the values for the new monitor..

Yes, I ran Xconfigurator in a shell window and got my xwindows back.

I am also curious about the color depth. What is the relationship between resolution, color depth and video memory? Suppose I have 1024x768 resolution and 16-bit color depth, what is the required memory?

Since I assigned 32M memory (shared memory) to video, why can't I get 24-bit color depth? Is the SDRAM not fast enough to support the 24-bit mode at the above resolution? Did anyone set 24-bit colr with 1024*768 by shared memory?

Thanks

Have a look at the "screens" section of your XF86Config-4, you should be able to change the default colour depth there.
