LCD monitor question

Hi all folks,

I just installed a NEC MultiSync LCD monitor, model - 1560NX. Previously I used NEC CRT monitor, MultiSynnc XV15+. RH7.3 detected it automatically but I could not toggle to change screen resolution.

I found /etc/X11/XF86Config-4 remained unchanged as follows

Section "Monitor"
Identifier "NEC MultiSync XV15+"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 31.0-65.0
VertRefresh 55.0-100.0
Option "dpms"

Section "Screen"
Identifier "Screen0"
Device "3Dfx Interactive, Inc.|Voodoo Banshee"
Monitor "NEC MultiSync XV15+"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1024x768" "800x600"

Kindly advise whether I need a driver for "NEC MultiSync LCD1560NX" and where can I have it download. Or just change the wording in Monitor and Screen Sections to replace "NEC MultiSync XV15+" with "NEC MultiSync LCD1560NX"

Thanks in advance.

You don't need drivers for displays. Only the horizontal and vertical refresh rates. Just like you, I replaced my CRT with an LCD two days ago.

I simply choose Generic Laptop Display Panel 1280x1024 and used the default settings. I changed the HorizSync and VertRefresh numbers to match the min/max given in the LCD monitor manual, but remember XFree86 will use the highest vertical refresh rate it can, which caused my display to be 1280x1024 75Hz. The manual suggested 60Hz, presumably because anything higher is useless on an LCD. So, I just stuck with the generic defaults; my monitor OSD menu says I'm at 60Hz.

Your display section should have the new 1280 resolution at the front of the Modes list:

SubSection "Display"
Depth 16
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"

Thanks for your advise.

Actually my RH7.3 has certain problem after crashed previously and it is now crashed again. I will forget it and will make a clean installation of RH9.0 on this box when time allows.

I install the new NEC MultiSync LCD1560NX monitor to a RH8.0 box. "Probing monitor" found it automatically. No driver is needed.

Do you know what will be the command line to change the screen colour


to check bad points on the LCD panel? Or I have to start another posting?
