       @Suiseiseki @EdBoatConnoisseur look what a lovely monitor I was able to got for around $15, it's the perfect size for what I need, except for... it stopped working!When I plugged it in, a little blue light appeared on the power buttom, bottom right, and later it began working, but with blinking (not the right term probably) vertical lines all over; since I didn't know the maximum resolution (XFCE would let me change to 1080p) I only tried the "classical" old ones, 1024x768, 800x600, etc.Because I didn't know what to do, I tried to power it off, it took some time until I realized it was neccesary to maintain the power button.And it never powered on again. I tried 2 different VGA cables and 2 plugs to connect different.I was told the DVI->VGA adaptor that I have might be harming the monitor (the motherboard has a HDMI and a DVI output for 2 monitors), and these monitors have VGA input.Please help me guys, tell me things to try before saying that it's dead....I'm so tired of this....

       @anokasion @EdBoatConnoisseur After unplugging and re-plugging the power with no input, can you get the on screen controls to come up (sometimes this requires pressing the power button and then mashing the control buttons)?Vertical lines can indicate a bad signal, or a dead monitor.If there's a power LED and it's not coming on at all with the power cable firmly in - unfortunately it's dead (crappy monitors can work fine for years and then randomly die).Monitors provide the computer a list of supported resolutions and refresh rates via EDID - so usually you can't select a non-working resolution (there are corner cases where for example, the 780 Ti supports DP 1.2 and therefore it is detected that 1440p@144Hz or 1440p@165Hz will work - but if you exceed 1440p@120Hz, you hit the display controllers clock limit).If you search the monitor model, that should tell you the maximum supported resolution - that looks like a 4:3 panel, so 1080p wouldn't be correct - I guess 1400x1050 or 1200x900 would be the maximum resolution.A DVI-VGA adapter cannot harm a monitor provided it's outputting a VGA signal and not big chunky volts - generally at worst you'll get a bad signal that is washed out or overscan off the screen (overscan in VGA-only monitors can be corrected via an OSD option - of course there are some HDMI+VGA monitors that don't have a overscan correct option(!), but at least you can use HDMI instead).

       @Suiseiseki @anokasion to be sure open up the display and take pics of the insides.yes i do not bother with software nor connectors and go straight to open up the display and checking what can be done and how repairable it is, but that is my bias as an electronics technician.
