not optimum mode

Hi Everybody, I have a Samsung 913N LCD Monitor which is giving me a problem (not optimum mode explained hereunder). The screen just blacks out, gives me an error saying "Not Optimum mode Recommended mode 1280x1024 60Hz" Normally this message stays for about a minute, to give you a chance to change resolution, and it goes, but now it stays for ever. The only way to get rid of it is by switching off everything wait for about 15 minutes and display comes back to normal again. I tried going to VGA mode and fix it but to no avail. I tried the same monitor on different PC`s but problem still persists, although it takes longer to happen on one pc than on another. In my opinion there must be a way to disable this annoying message !!! The problem is how? Either from the buttons on front of panel or from its software. Perhaps there is a way to enter the monitor`s software and disable it from there. The funny thing is that it never happens while installing a fresh copy of windows until it comes to change the resolution (and not always) Before the problem started to happen I could easily adjust the resolution any MODE I like!! Any help on how to solve this will be extremely appreciated. Thanks in advance

I have a tried and working solution for "Not optimum mode" -problem of Samsung 913n. The problem is mechanical, bad solderings.

Take the display apart. Remove the logic card (not the power card). It is the card that the display cable enters in.

If it is easily done, remove the stickers on the card. Into the four holes in the corners of the card attach screws with nuts so that the card will stay like on four legs with the component side up.

Set your kitchen oven for 200 degrees of Celsius (390 Fahrenheit) with upper and lower heat on. When the temporary is reached, put the card in the middle of the oven standing on its legs. Close the door.

Count 8 minutes and then cut the power and open the door. Don't touch the card until it is cooled well.

Remove the screws. Put the card on its place and assemple the display. Test.

Does it exhibit this behavior on a different computer? If not, the problem could be your video card.

El monitor tiene una averia; abrirlo localizar chip" Novatek NT68F63LG" y entre las patillas 5 y 6 soldar una resistencia de 47 ohms, y problema resuelto, aun así se aconseja refrigerar con un radiador este chip.
