For most of us, we want to save money and one of the ways to do so is to buy secondhand items. Let’s focus on secondhand computer monitors. Based from experience, buying secondhand monitors is quite safer than buying other computer parts especially the internal computer components. It’s quite easy to see problems with a monitor as it would usually show up immediately as you test it. Let me share some guidelines in buying a secondhand computer monitor.
Secondhand monitors may cost you around 75% of its original price or below depending on the model, its condition, how long it was used and if there is still warranty. A monitor in good condition that was used for 2 years with no shop warranty could sell for probably around 50% or below its original selling price. Check price lists from different computer shops so that you can have a reference to its retail price. This way, you can also determine if the price is fair or not.
When buying secondhand monitors, it is imperative that you test it thoroughly. Make sure that it works fine for at least 10 minutes or so. If it’s a CRT monitor, the colors should be sharp. There should be no discoloration especially on the edges. If there’s any problem with the CRT, you’ll most likely see it as you test it. Check the functionalities such as brightness if they work fine.
Also, make sure that it will work based on its specification. Check its maximum resolution and refresh rate. It pays to do a little research on the internet before buying a specific model. Check its product specifications from the manufacturer’s website and you should expect it from the secondhand monitor that you are planning to buy.
Nowadays, LCD monitors are probably the mainstream computer monitors for home use. However, with its more advanced features, you may need to exert a bit of extra effort in examining the monitor. Make sure the functions are working properly such as the color, brightness, contrast, etc. If there are other features such as USB connectivity, HD video playback, etc. Make sure to test them. Prepare a high definition video on a USB drive and see if it plays well.
However, the most important thing to note is that LCD monitors are susceptible to dead pixels. Test the monitor by turning your background into pure white and see if there are any pixels that have no color. Place a colored image atop that suspected dead pixel and if it still is black, it most likely is a dead pixel. This may be due to a low-quality monitor or misuse and length of use. I suggest that you look for another LCD monitor.
If you’ve decided to buy a secondhand monitor, make sure it has the complete package as much as possible. Check the box, manuals, drivers, cables, etc. Ask for personal warranty if it doesn’t have shop warranty anymore for your assurance. 7 days is probably more than enough to fully test the monitor. Play games, watch movies and see if there are any problems while doing desktop work. But of course, it’s still your choice if you like to buy a secondhand monitor. Buying brand new computer parts and peripherals is always recommended.
