The monitor says non-optimal mode, what should I do? Non-optimal mode on Samsung monitor. Reasons for non-optimal regime

Does the monitor work for a while and then show the “not optimal mode” sign? And this happens even when this optimal mode is set in the settings? And sometimes the monitor shows nothing at all? Meet the Samsung 710N - this problem is congenital and manifests itself over time.

Samsung Syncmaster 710N - non-optimal mode and that's it!

We will open it, repair it and bring it to life!

And the first question: how to disassemble the Samsung Syncmaster 710N monitor without casualties? I couldn't do this. From the back side, unscrew the 4 bolts securing the stand and 2 screws at the bottom edge on the sides.

Then we use an expired bank card (thank you, Alfa Bank, for not taking it) and carefully separate the two halves of the case.

IMPORTANT: you need to remove not the front frame, but the back cover, because the front frame is secured with one screw inside (right under the Samsung inscription at the bottom). I first removed the front frame (there is strength - no need for intelligence). This is the screw.

Having removed both halves of the plastic case, we begin to remove the metal back cover. It is secured with four screws on the side ends.

We removed the cover and enjoyed the insides of the Samsung 710N monitor in all its glory: power board, signal board - complete geekporn!

Samsung Syncmaster 710N giblets - general view of the boards

Here we are more interested in the signal processing board, it is greener and on the right side. And this is where the VGA cable is connected.

On it we are interested in the processor - the rightmost microcircuit in the shape of a square. It is because of this that we get the “non-optimal mode” error in any mode at all.

Syncmaster 710N processor - it is to blame for non-optimal mode

People have two options for fixing the “non-optimal mode” problem:

1. Warm up the processor with a soldering hair dryer to eliminate the solder issue.
2. Short-circuit two legs of the processor: the two upper legs on the right side

I chose the second option because I was watching an interesting movie and didn’t want to make noise with the hairdryer. Therefore, turn on the soldering iron and go!

IMPORTANT: many microcircuits do not like prolonged exposure to high temperatures! 250 degrees is considered a safe temperature for long-term soldering. Use an adjustable or low power soldering iron.

250 degrees is a safe soldering temperature

Once two legs of the processor are shorted (with a piece of wire or just a drop of solder - it doesn't matter), you need to make sure that the adjacent legs are not affected. Excess solder is cut off with a knife. This is what a healed Samsung Syncmaster 710N monitor processor looks like

We put everything back together, turn it on and rejoice! Now the monitor works in all modes and does not show off!

On the eve of the New Year holidays, I helped my relatives assemble and set up an old computer, suitable only for office work. The task was to connect all the components to each other, repair or install the operating system, install drivers for the devices and set up wired Internet.

In the process of setting up the operating system, the ancient LCD monitor Samsung SyncMaster 710v died a long life, displaying the message “Not optimal. mode. Recommended mode: 1280×1024 60Hz.” Moreover, such a message cannot be removed; turning off and turning on the monitor and other similar manipulations can be immediately forgotten - repairs are required.

The solution was quickly googled. The search turned up quite a lot of answers, but the best one seemed to me to be a recent article: Non-optimal mode on Samsung SyncMaster 710v (based on Novatek NT68F63L) on the blog of a person who professionally repairs computer equipment.

As it turned out, the failure of monitors based on the Novatek NT68F63L processor is a disease that has long been known to experts, and not only Samsung is susceptible to it. To avoid problems, knowledgeable people advise adhering to the recommended operating mode, namely, always keeping the frequency strictly at 60 Hz.

Meanwhile, there were only a few days left until the New Year, and I soon had to leave the city. Therefore, we decided not to put off the renovation indefinitely. The very next day we (I helped my son-in-law, Andrey) had at our disposal a household soldering iron, a 50 Ohm resistor, burning eyes and hands trembling with impatience.

The monitor was disassembled in five minutes according to the above-mentioned instructions of the kind person, and now the board with the processor appeared before our eyes:

You need to solder the resistor between legs 5 and 6 - the repairman knows how they are determined, there are no markings there, but if you look at the photo, these are the two outer legs in the upper right corner of the processor (from the side of the logo printed on the chip).

Unfortunately, no matter how hard we tried, we were unable to cope with the task. Using an ordinary soldering iron, it is almost impossible to solder two adjacent processor legs to a resistor without shorting everything out.

Therefore, taking into account the growing time pressure, as well as the zero residual value of the equipment being repaired, it was decided to act in the most barbaric way possible - to warm up the processor over an open fire. Turning the monitor over a burning candle, we heated the processor for a minute with quiet trepidation, thoroughly smoking it.

When everything cooled down, I collected the patient and connected him to the computer. To everyone’s surprise, the monitor has been working properly in daily mode to this day, and almost two weeks have passed since then! I'll keep you posted.

UPD: a civilized method of treating “bayan with mikom”:

When you start Windows or a game, a black screen appears on the monitor and the message “Non-optimal mode” appears. Recommended mode: 1280×1024 60hz”. Depending on the monitor, another resolution may be specified: 1920×1080, 1440×900, 1680×1050, 1600×900 and others. Most often, this depressurization problem occurs in older monitors, mainly from the Samsung line. We'll show you why the error occurs and what you can do to solve the problem.

Reasons for non-optimal regime

Modern games run in fairly high resolution. For example, many of them can already be safely launched in 4K. Therefore, the main reason for the bug is that by default the game launches in a mode that your monitor (usually square) cannot display, or launches in downscale (low quality). The crash occurs in Stalker, Dota 2, Resident Evil 7 and other heavy applications. An equally rare cause is crooked/outdated video card and monitor drivers.

It’s worth mentioning separately about “Non-optimal mode” when starting Windows. For example, you reinstalled the OS/drivers, changed the monitor, or decided to use an adapter from VGA to HDMI, and ended up getting a black screen. Next we will describe solutions for all such nuances.

Fixing an error when launching games

So, first, let's look at all the initial steps that you can follow and quickly fix the problem. In general, they relate to setting game parameters to the requested ones.

Checking the video card and monitor drivers

If this failure is constant for you and occurs the first time you launch all applications, then you should understand that programs cannot determine what resolution will be normal on the computer. The main reason is that the monitor in Windows is defined as non-PnP (Plug and Play). The solution is to change the display driver.

1. Open Device Manager, right-click on Monitor and select update.
2. Click on “Search for firewood in your computer”, and then select “Driver from the list of already installed” at the bottom.
3. From the list, select a generic PnP monitor.
4. After this, the driver should normally detect the range of games and, accordingly, launch them without a black screen.

If Windows won't start

1. Turn on the PC, press F8 while loading - this will open additional launch options.
2. Select “Safe Mode” first. Open Device Manager there.
3. Right-click on your video card and select “Updating Drivers”– from below “Search on your computer”– from below “Select from a list”.
4. Here we select the previous version (based on the date) and confirm and restart the system.

Another option would be to select via F8 options “Enable low resolution video mode (640x480)”. After starting the PC, load "Control Panel", there we look for the tab “NVIDIA Control Panel”. If you have a different video card, see the instructions for it. In NVIDIA you need to check the following:

1. Tab "Display" – “Changing resolution”. Set the resolution requested in the error. The frequency should be 60 Hz. We apply.
2. “3D Settings” – “Adjusting Picture Settings”. Check the third box: “Performance Focused”. We apply all changes.
3. The last step will be “Installing PhysX Configuration”. Here we select our video card from the list and apply it. By the way, this is true for Samsung.

Conclusion

All these above options should solve the problem “Not optimal. Recommended mode mode". In rare cases, such an error is written due to adapters when they try to connect modern video cards to monitors with a VGA input. Here we can only advise you to find high-quality adapters, which are lost among the Chinese counterparts. If nothing helps at all, it’s worth checking your monitor for hardware damage at a service center. In case of difficulties, write in the comments, we will try to help you.
