Unhappy Samsung LCD TFT monitor Not Optimum Mode


In the Samsung 710n ou 510n, the messagem "not optimum mode - recommended 1280 x 1024 60Hz" is a hardware problem.
There is no configuration to solve this problem.

I've tried to reply the question in a forum, but it's my first post and you know... Couldn't reply.

Check the display settings in your X config file. make sure it is set to deafult to 1280x1024 in teh Modes seciton.

/etc/X11/xorg.conf is the config file.. or your distro may have a graphical tool you can use to make the changes but you didn't mention what you are running so....

Code:
Section "Monitor"
        Identifier      "Visual SensatKDS"
        HorizSync       30-64
        VertRefresh     50-60
        Option          "DPMS"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "Generic Video Card"
        Monitor         "Visual SensatKDS"
        DefaultDepth    16
        SubSection "Display"
                Depth           1
                Modes           "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection
the config above defaults to 16 Bit color at a res of 1280x1024.. at 60 Hz... of course the vrt and horiz rates in this config are for my LCD display your's may be a little different.

That is my old X config to get default 1280x1024 @ 60 hz on my LCD flatscreen..

That is part of /etc/X11/xorg.conf

not that it mkes any difference but here is a section of my current config..

Code:
Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       30-82
        VertRefresh     50-76
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "NVIDIA Corporation NV20 [GeForce3]"
        Monitor         "Generic Monitor"
        DefaultDepth    24
        SubSection "Display"
                Depth           1
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1280x1024" "1024x768" "800x600"
        EndSubSection
EndSection
1280x1024 @ 75hz refresh is what I am getting from this config. perfect for my LCD.

Temporary FIX!!!

I found another site to night where someone seems to have found a temporary solution. "UNPLUG the monitor from the power supply for about 5 - 10 minutes". The CPU can be left on but unplug it from the power source and not just behind the monitor. Then after it comes back on, change your mode/display settings. I had to wiggle the power cord on the back of the monitor a few times when the blippen message can back again. But after a few wiggles and changing the mode lower than the recommended 1280 X 1024, I finally got it to work. This seems to be a temporary fix from what I read. After a while the problem came back for the other users since it is a problem with a switch/connection or something in the monitor plug. I guess this is a known problem with SAMSUNG. If your monitor is still under warranty, contact them and they will repair it or maybe even replace it. I hope this works for you as well since it took me about 4 days to find something that works other than VGA mode. Good luck and I hope this helps.

Dave

Talking

The problem is related to heating. So do not waste time on settings.

Just cool it.

I learned it with my Samsung 710N, by 34 degree Celsius.
