How to properly test the monitor after purchase?

Answer 1

1. Before choosing, read the reviews and pay attention to the problems that they describe;
   
2. Visually check the condition of the package (often if the box has been opened or battered, there will be a defect);
   
3. Unpack, keeping the integrity of the package;
   
4. Check physical integrity - scratches, chips, cracks (with broken pixels, you can simply hand over, and physical damage will be attributed to you and you will have to swear);
   
5. Turn on;
   
6. Often, monitors already have built-in tests (at least colored backgrounds to search for dead pixels), if there are no built-in tests, then connect and check from any device;
   
7. In addition to dead pixels, pay attention to the uniformity of the backlight;
   
8. Look at the subject of gray pixels - several times I met such gray nasty defects a la dust on the matrix;
   
9. Check completeness;
   
10. Check serial number;
    
11. Continue field testing
