Title: screen resolution on Philips LCD 22 inch monitor
Post by: beerstein on April 12, 2012, 09:54:08 AM

This monitor (model Brilliance 220X1) comes with a recommended resolution of 1680x1050 at 60Hz
It works fine with TCL 3.84  with 1024x768x32 as listed in the respective file: /tc/.xsession

BUT ; It does not work in TCL 4.3! Here I am getting a black screen and I am asked to switch to 1680x1050 at 60Hz (monitor message)
the closest I can get using the VESA button from the control panel is 1600x1200  #17 from the menu
This resolution works fine in TCL 4.3 but items on display are getting too small.

Question: How can I set my screen on TCL 4.3 to 1024x768x32 ? Editing /tc/.xsession alone did not work.

Thank you for your help

Hi beerstein
Try changing  1024x768x32  to  1024x768x32x60  in  .xsession  and see if that helps.

Hi Rich: Thank y'  for that. It does not work. Here is my /tc/.xsession:

/usr/local/bin/Xvesa -br -screen 1600x1200x16 -shadow -2button -mouse /dev/psaux -nolisten tcp -I >/dev/null 2>&1 &
export XPID=$!
waitforX || ! echo failed in waitforX || exit
"$DESKTOP" 2>/tmp/wm_errors &
export WM_PID=$!
[ -x ./.setbackground ] && ./.setbackground
[ -x ./.mouse_config ] && ./.mouse_config &
[ $(which "$ICONS".sh) ] && ${ICONS}.sh &
[ -d ".X.d" ] && find ".X.d" -type f -print | while read F; do . "$F"; done

This one works. But as soon as I change the "1600x1200x16" to 1024x768x32  or 1024x768x32x60 or 1024x768x24
I will get the black screen. May be there is problem with the display ratio?

I also discovered that the /tc/.xsession file from the other PC (TCK 3.84) on which the monitor works fine in 1024x768x32 looks slightly different.
Was there a change in display config from TCL 3.XX to 4.3  ?

No, neither Xvesa nor the default resolution had changed.

Hi beerstein
Try changing   -screen 1600x1200x16   to   -mode 0x013C

Try to see what happens with

Code: [Select]

-screen 1024x768x16

Hi rich: when I try " -mode 0x013C"  I will get a dark screen but X is running.
HI tinypoodle: when I try "-screen 1024x768x16" it does not boot into X and stays at the CLI

Hi beerstein
OK, let's bump it down a little further. Try    -mode 0x0117

This did not work either. Black screen and I can not even get into the console with CTRL- ALT- F1
It is strange that the monitor works with TCL 3.8.4 but not in TCL 4.3
1600x1200x16  seems to be the only setting which works in TCL 4.3

Hi beerstein
What does   lspci   (pci-utils.tcz) give you?
