Help SOLVED recommended mode 1280x1024

By Jacky Howe ·
This is what has happened to my 17" Samsung 713n <i>not optimum mode recommended mode 1280x1024</i>
Here is a good insight into what is happening. Thanks to paras7664 for the detail.
This monitor is no longer under warranty and I am sure that it can be repaired I just need to know how to do it. It is my first LCD and has performed really well until now.

Self test for your monitor..

Self-Test Feature Check
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see the "check signal cable" setting box.

Warning Messages
If there is something wrong with the input signal, a message appears on the screen or the
screen goes blank although the power indicator LED is still on. The message may indicate that the monitor is out of scan range or that you need to check the signal cable, of which you get this message:
" not optimum mode recommended mode 1280x1024" "?".

Judging the monitor's working condition:

If there is no image on the screen or a "Not Optimum Mode","Recommended Mode : 1280 x
1024 60Hz" message comes up, disconnect the cable from the computer while the monitor is still powered on.
􀁻If there is a message coming up on the screen or if the screen goes white, this means the monitor is in working condition.
􀁻In this case, check the computer for trouble.

Please post back if you have any more problems or questions.

Monitor or Computer?

by TheChas In reply to Help SOLVED recommended m ...

My first question after watching the video is have you tried connecting a different monitor to the system?

Or, have you connected the monitor to a different system?

I did not hear any POST beeps from the computer. So, I suspect that the computer itself is not getting all the way through POST.

The message on the monitor is "normal" for the startup and BIOS screens as they only display in low resolution.

I have tried with different monitors and they are working fine. All PC's are posting properly. Monitors have never been my forte and I can reset the basics on a CRT but I have never had an LCD apart. With an error message like this I wouldn't know where to start anyway. I suppose if I can't find a fix for it I will get to have a look at the inners, just to have a look.

A bit more info

by Jacky Howe In reply to Help SOLVED recommended m ...

I was using the monitor as a second display. The PC display has been set at 1024x768 at 60Hz forever. It has always been set like this as all of my PC's with 17" monitors are set at this resolution. I wasn't trying to adjust the display settings it just decided to happen.
The only way to remove the error message on the PC's is to remove the power to the monitor for 5 mins and then reconnect. Within 20 mins the error message is back. The Video card that I am using is a NVidia GeForce FX 5200. The first PC that I used to test with has a NVidia GeForce MX 4000 and the display was set at 1024x768 at 60Hz. The second PC to test with has a NVidia GeForce 7300 GT and the display was set at 1024x768 at 60Hz.
The monitor has a built in autotuner that appears to work as when I connect to the first PC it will show the display with the error message and you can press the autotuner and it will scan and then you can use the monitor for 20 mins before the message appears again. This feature doesn't work all of the time. The manual settings on the monitor don't seem to allow you to change the default 1024x768 setting and if I use the PC's to set it to 1280x1024 I get the error message.
I removed the video card from the primary PC and gave everything a spring clean as I originally thought that it was a problem with the video card. If I disconnect the monitor cable from the PC's then the "check signal cable" setting box will appear. I am sure that this is definately something to do with the monitor. I seen a post where this problem has been fixed under warranty and the poster recieved the same monitor back.
After checking the responses this morning I reconnected the monitor to the NVidia GeForce 7300 GT that has Vista installed and tried to manually change the resolution to 1280x1024 at 60Hz. It will not except the settings. The screen goes black and then returns to 1024x768 and at the moment there is no error message. When I tried that before it errored out. It doesn't seem to matter whether the OS is Vista or XP.
At the moment it will not except any resolution above 1024x768 but I can lower the resolution. It has been working for an hour this time around with no error message. That is all that I need an intermittent problem. Installing the Monitor drivers hasn't helped.

If it's any consolation, i use a HP wide 20 incher.

And you can set it to well above your settings through the monitors own OSD. Also have a few LG monitors for years without any problems.
Just thought that you might/need or want to change in the near future.

Please post back if you have any more problems or questions.

I can't afford

by Jacky Howe In reply to If it's any consolation, ...

a new monitor at the moment and I have gone back to using a 17" CRT as the second display. My main monitor is 22" and all of the 17" CRT's that I have will display 1280x1024 just not the Samsung. It appears to be stuck on the 1024x768 as when I change the resolution down to 800x600 and restart the PC the settings are still 800x600 but if I open the menu on the monitor it is still set at 1024x768. Leaving the settings on the PC at 800x600 and then using the autotuner it will set as 800x600 on the monitor. When I try and bring it back to 1024x768 it gives the error message. It appears that the autotuner is working intermittently.

Just be thankful it's not your Test Monitor

by OH Smeg Moderator In reply to I can't afford

I got caught once with an Intermittent Monitor going black and because the computer came in what they problem I wasted hours trying to fix the computer when the Monitor was faulty.

Particularly galling that one was.

Go down to your Local Electronics Store not Dick Smith or Tandy and buy a can of Freezer Spray. Open the monitor up and in the failed condition hit the Power Board one component at a time with the freezer spray till you have hit everything and then move onto the Tuner Board if it doesn't start working again. You may get lucky and it's just a bit of crud inside the unit that is causing the problem.

I suppose that I am lucky in that regard as I have recently moved a couple of monitors around because a CRT went to silicone heaven. My test monitors are still CRT. I will try that suggestion but isn't freezer spray the same as compressed air. I use an old eager beaver for cleaning PC's as there is no moisture involved.

3 Year Warranty in US

by willcomp In reply to Help SOLVED recommended m ...

Take a look at manufacture date on rear of monitor. In the US, Samsung LCD displays have a 3 year warranty.

I have a 710n that just turned 4 years old and the 713n is a newer model (I think).
