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.

I think

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

(and this is just my wild guess), because I have sort of had the same error.

but how I read this (and don't blame me but I sometime read oddly...) not optimum mode, recommended mode 1280x1024, i.e., not in correct display settings.

this is done on the screen, in the menu (some monitors have an auto option, while others don't) so you pretty much have to change it to 1280x1024.

if not... I am clueless

Jacky this happens because the Display settings of the Video Card are not

Up to the Minimum Input of the Monitor. If you have a CRT or any other monitor connect it up to the computer and when Windows Opens reset the Video Resolution to what Samsung Recommends.

Try to install the Samsung Drivers as well here and check the Monitor on a different computer. I've seen a similar thing happen with a Bad Power Supply where the No Connection Message would appear when power was applied to the system but when it was turned off the Monitor behaved itself perfectly. That again was on a Samsung Monitor but it was a 17" CRT Monitor as I can not use LCD or TFT Monitors they give me headaches.

This should allow a Display to be shown when Windows Starts even if there is nothing displayed on the screen till then.

I don't know what's happening this week but that's about the fiftieth Samsung Device that has carked it. My own Color Laser Printer spat the dummy and is insisting that the Waste Toner Cartridge is Full or Not Fitted. Well when this started the Waste Toner Cartridge was getting full but since I've replaced it with a new one it's still doing the same thing. The customers have also had a rash of Samsung Products dieing all of a sudden this week for some reason as well. Not sure what's going on at the moment but there seem to be a lot of them choosing to head to Silicon Heaven for some reason.

Well it is a throw away society

and nothing that is built these days are designed to last. Tried all of the suggestions to no avail. I have ruled out everything except the monitor that doesn't seem to be excepting the input properly. 3 different PC's with 3 different video cards. There seems to be a connection to the power as well because when it is removed for 5 mins the monitor will come back to life.

Jacky have a look at the Power Supply Board in the Monitor

And check for any Faulty Components. Most likely it will be a Heat issue so grab a can of Freezer Spray and spray the components one at a time when it's not working and see if it springs back to life. You may find a simple bit to replace that way but if it's something like a Surface Mount Transistor, Diode or Resistor I would be looking at keeping the unit for spare parts. I just don't like to throw things away that may be useful latter.

Yes, probably it' s overheating.

by MrCyber In reply to Jacky have a look at the ...

The same happened to my SyncMaster 713BM. I teared the thing apart and found that there is a chip (SE7888-LF) that is quite hot. Cooling it with compressed air helped. And as opposite: when I heated it with air-drier - the fault again appeared. So it migt be that it cannot handle even the recommended resolution when getting hot. It is very hard to replace, so the solution may be a tiny fan installed against this chip. There is some space for that, but I haven't tried it yet.

was a bad MCU IC. That component is on a board that needs to be replaced. It ended up cheaper to replace the monitor.

Off topic - re your printer problem

by ozi Eagle In reply to Jacky this happens becaus ...

Hi Col,

I don't know if this applies to your printer, but I have found that some are sensitive to sunlight shining on them. The case is so thin / translucent that direct sunlight activates internal sensors and cause all sorts of problems.

Try surrounding the printer with cardboard to check.

This is what i have found in the manual....

Can you see "Not
Mode : 1280 x 1024
60Hz" on the screen?

You can see this message when the signal from the video card exceeds the maximum resolution and frequency that the monitor can handle properly.
Adjust the maximum resolution and frequency that the monitor can handle properly.
If the display exceeds SXGA or 75Hz, a "Not Optimum Mode","Recommanded Mode :
1280 x 1024 60Hz" message is displayed. If the display exceeds 85Hz, the display will work properly but the "Not Optimum Mode","Recommanded Mode :
1280 x 1024 60Hz" message
appears for one minute and then

Please change to the recommended mode during this one-minute period. (The message is displayed again if the system is rebooted.)

Check the following items if there is trouble with the monitor.
1. Check if the power cord and the video cables are properly connected to the computer.
2. Check if the computer beeps more than 3 times when booting.
(If it does, request an after-service for the main board of the computer.)
3. If you installed a new video card or if you assembled the PC, check if the installed the adapter
(video) driver and the monitor driver.
4. Check if the scanning ratio of the video screen is set at 75Hz.
(Do not exceed 60Hz when using the maximum resolution.)
5. If you have problems in installing the adapter (video) driver, boot the computer in Safe Mode,
remove the Display Adapter at the "Control Panel→System→Device Administrator" and then
reboot the computer to reinstall the adapter (video) driver.
edited for added info.
