Samsung syncmaster 913v gives message ' not optimum mode"

I just resolved this problem for my SyncMaster 913N.
It seems to be a known issue, however it can take quite some time for the problem to occur. In my case about 3,5 years, so well out of warranty.

Short term solution: unplug your monitor from power. The switch on the front is not good enough. Pull the plug and leave it for an hour or so (all night if you can). Good chance the monitor will work next time you power it up.
The problem will is likely to come back..

Permant fix requires some basic soldering as per this video:



I just managed it and it has been ages since I soldered a resistor so you may very well be able to do it. I spent $25 on tool and part and saved me from buying a new monitor.

hello
I am a technician-informatic. I have repaired about 80 Lcd Samsung monitors with theese problems. I offer the repair manual.
Manual has been done with the experience of the repairing Samsung Lcd monitors. Manual was made by me and shows how to open monitor, how
to solve dark screen problem, how to check and replace capacitors, how to solve the problem non-optimal mode (without reprogramming MCU or
changing the main board) photo are included. 100% functional. The repair process is very simple 30-40min. (does not need a lot of
experience in electronics and expensive instruments) and is not expensive. With this manual you can solve problems by yourself and save
money.

"Not Optimum Mode 1280x1024 60Hz"
- The monitor turns on but turns off by itself, the LED blinks green.
- If you detach from the PC points to "control cable" the picture runs continuously in the vertical direction or presents while line , and
as soon as it is reconnected, the monitor goes off.
- The monitor does not turns on and dont dispaly anything, the LED blinks green-lit, if you detach from pc points to "control cable".
- The monitor turns on, works well some time, but after a window apiers "Not optimum mode. Mode recommended 1280X1024 60Hz"
- The monitor turns on, works well only with low resolution 800x600, when try to change a window that reads "Not optimum mode. Mode
recommended 1280X1024 60Hz"

the manual you can find on ebay (my ebay name is asnerejas123):

Sounds like your resolution is not set correctly.

Try going to Start-->Control Panel-->Display and choose the Settings Tab

Under there change the resolution slider bar to 1280x1024

Should do the trick!

1. please check by pressing num lock or caps lock key to verify that your machine is booting up, if yes then check the cable and if after changing the display cable it doesnt show up anything, it means you have a faulty unit

2. if numlock/caps lock key doesnt work, then your machine is not booting up, please check for loose ram etc.

thank you

the fault is the backlight, Samsung has designed it as when one of the baklights are faulty the unit shuts down.

in safe mode adjust the resolution lower than 1280x1024
then restart and then install the driver again the driver is crrupted than install the right driver problem could be solved

Hi Guys.
I have had this problem and after a bit of searching found that it is a known problem.
Give Samsung a ring and if it's in warranty they will replace it
