Question about Samsung SyncMaster 913V 19" Flat Panel LCD Monitor

Resolution Issue "Not Optimum"

I got a sumsung SyncMaster 913v and one of the problems seemed to be the old 15 pin cable so i bought a new one and plugged it in and it worked. The resolution wasn't to my liking though so i changed it from 1280x 960 to 1280 x 1024. Anyway when i did that the screen went black and nothing ever showed up. I rebooted the computer and this message started floating around the screen "Not Optimum Mode. Recommended Mode 1280x 1024 60Hz" the screen looks like the one that shows up when you plug in the monitor without plugging in the 15 pin. the message is in a box like the "Check Signal Cable" window. Anyway I've tried changing the resolution back all different types seeing which one worked previously because im not totally sure that 1280x960 was what it was on. And the settings have never left 60Hz. Any advice or a solution would be great

    I have exactly the same problem as davcar with my Samsung 913V. The "not optimum" message goes away if I power off the monitor for at least 10 minutes and then power back on, with or without rebooting the PC. Sometimes it will be OK for hours, and other times it goes out in a few minutes. I can force it to repeat the problem by just trying to change the screen resolution. Right now I am stuck in the present resolution since any change attempt will cause it to go black and bring up the floating message window. The monitor is otherwise fine and I have tried it on two PC's and two different cables with the same results. Very frustrating. Any further suggestions before I go aout and buy a new monitor?

    I have the same problem. It occurs when the monitor changes resolution or sometimes after it has been on for a period of time. I get a blank screen or "out of range error". Most commonly this problem occurs when switching to the resolution 1280x1024, eg starting a game from a menu or similar. I am sure it is not my video cards because I have two brand new 9600gts which I was able to test both independently and in SLI, always with the same results. Also, When I tested my system with a friend's asus 22" monitor (at the same and higher resolutions), I was unable to repeat the problem. So far I have discovered, as another user has described, turning the monitor off for 5 minutes will sometimes help.

    I have the same problem
    and the solution is not realy a solution, only a way to get a new monitor, but my warranty is over
    so is there anothe solution?

    I have the same problem. It always happens after:



    • prolonged time of use;

    • exiting games;

    • switching screen frequency rates (60, 70 or 72hz)

    The "turn off monitor" trick works, but it's annoying. It's probably a HW problem, since I've tried several drivers of my graphics card (Nvidia 7300 GT). Guess it's time to buy a new one...

    PC boots up ok but only signs of life from monitor is 'Check Signal Cable'. Its about 3 years old so out of warranty. I'm hoping someone finds a simple cure. In the meantime, I'm using my old 17" CRT

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

Samsung syncmaster 913v gives message ' not optimum mode"


The 913V has a native resolution of 1280x1024. If you use a higher resolution than that, you'll get slightly blurry text. If you use a lower resolution, then images will be slightly choppy around the edges.

To get rid of the message, set your resolution to 1280x1024.

In Windows XP, you do this by right-clicking on the background (desktop) and selecting "Properties" to bring up the display properties.
Select the tab marked "Settings" and look for a "Screen Resolution" slider. Move that slider to the right until it displays "1280x1024" and hit "OK"

Syncmaster 913v 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.

Cannot set my SAMSUNG SYNCMASTER 710V MONITOR RESOLUTION


When you can't change the screen resolution then most likely only the default VGA driver has been installed. You need to install the graphics driver of the video card that is installed in your computer.
To check which graphics driver is installed, click on Control Panel - Display - Settings - Advance - Adapter tab. If the graphics adapter is set for Standard VGA then the graphics driver was not installed.

Not optimum mode


This means your computer windows resolution is not display in the correct resolution which your samsung LCD will take.

What you need to do it boot the computer in safe mode. (pressing F8 at start up and select safe mode) This should bring the windows to start up in the generic 800x600 resolution.

Once you are able to see the display in safe mode, go onto the display properties and change the resolution.
* right click on desktop -> properties -> settings

Please rate this if it solves your issue. If you need further assistance please post.

Samsung 913V LCD Monitor--No display when vga plug plugged in


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.

Syncmaster 913v color problem


Appears to be something in the connection. Check the video cable and pins on the video connector. Also verify the color settings have not been changed on the monitor. There should be an area where you change the RGB levels.

New Samsung monitor returns only a blank screen when turned on. what can I do?


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):

I have the samsung syncmaster 913v 19'' lcd monitor.Recently,the thing blacks out after 1 hr or so and the not optimum mode signal appears.I cannot raise the resolution above 1024x768 without blacking out...


It seems like a lot of people have experienced this issue after a year or two of use. There are two things people reported working...

Try adjusting the refresh rate higher or lower... 60Hz is usually stable in any resolution.

Completely unplug monitor for 5 minutes or longer. Seems like it works for some and not others.

Samsung has a 3 year warranty. If neither solution works, see if it is still under warranty.

Good luck!
