Could the monitor break from working in tandem with another?

Question

Monitors

Hello. I'll try to describe all the initial data in as much detail as possible: there is a GTX 780 video card with two DVI ports (DVI-I dual and DVI-D dual). The main ASUS monitor with a resolution of 1920x1200 is connected via DVI-D dual and operates at a frequency of 59Hz. I bought a used Samsung SyncMaster 740BF monitor with a resolution of 1280x1024 and two ports - VGA and DVI. I connected it to a DVI-I dual video card via a VGA cable with an adapter to DVI-A, because when I tried to connect both monitors via DVI, the image was only on one.
The first day the Samsung worked fine. There was a slight ripple (but I attributed this to the analog connection) and in 10 hours of operation it warmed up quite well. I didn’t pay attention either, because the main one is also heated, albeit weaker. On the second day after loading Windows, the Samsung itself did not catch fire. I don’t remember what I did, but in the end the image appeared. Again, during the day it worked fine, it warmed up as on the first day.
Today, after booting up again, it did not turn on. If I pressed the on / off button on the monitor, then the desktop image appeared for a second and disappeared. This time, fiddling around with the desktop and video card settings didn't help. The monitor was defined in them, its settings were available. It was 60Hz, put 75.
And after that, that's all. On the monitor, the image no longer appeared even after turning the button on / off. Instead, horizontal white stripes appeared, here is a photo i.imgur.com/UokjIMl.jpg I tried to connect it without a second monitor through an adapter (VGA -> DVI-A) - stripes. Through VGA without an adapter from an old computer to a VGA port - stripes. Via a DVI-A cable to the DVI-I dual of the new comp - band.
Hence the question - why could this happen? Could it be due to the fact that the monitor itself is kosyachny (but then how did he manage to work for two days, it seems to be normal)? Or maybe it's my own fault, I connected and configured it incorrectly (although what settings are there, I connected both, set which of them is the first, which is the second, and everything seems to be)?
And if I take a new monitor (this time in a store, so that with a guarantee), then should I look at models with DVI, can two monas work simultaneously when connected to DVI or take it with VGA?

Answer 1

This is called the passage of circumstances. Take a monitor with dvi/hdmi

Answer 2

If the scan was 60 and the resolution was set to acceptable, then I assume that the monitor was just tired. It is necessary to look at the power board and SCALER, maybe fix it by replacing dried electrolytes. Two monitors must live on different DVI outputs. There are so many of them soldered for this.

Answer 3

In general, I bought a normal asus monitor with dvi and vga outputs, connected it via dvi. Everything immediately worked without fuss and settings. It was worth turning on the computer, the image appeared on both monitors, I did not see any problems for almost a week of use. It's just that the Samsung apparently really was running out.
