How to use Acer AL2016W monitor under X.Org
The monitor is not working properly with default settings: the bottom of the picture is not displayed. Fortunately I discovered, that the monitor works well with CVT timing. I generated the proper modeline with the following software:
http://www.uruk.org/~erich/projects/cvt/Here is the monitor section for xorg.conf:
Section "Monitor"
Identifier "Monitor0"
VendorName "ACR"
ModelName "AL2016W"
HorizSync 31-84
VertRefresh 56-77
# Max dot clock (video bandwidth) 170 MHz
# DPMS capabilities: Active off:yes Suspend:yes Standby:yes
# Mode "1680x1050" # vfreq 59.852Hz, hfreq 65.179kHz
# DotClock 146.000000
# HTimings 1680 1784 1960 2240
# VTimings 1050 1053 1059 1089
# Flags "+HSync" "+VSync"
# EndMode
Modeline "1680x1050_60" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -HSync +Vsync
EndSection
After that you should add the mode 1680x1050_60:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 1
Modes "1680x1050_60"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 4
Modes "1680x1050_60"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 8
Modes "1680x1050_60"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 15
Modes "1680x1050_60"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 16
Modes "1680x1050_60"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1680x1050_60"
EndSubSection
EndSection
