(1) lack of color
Some customers bought an electronic cash register, and soon after, the display of the electronic cash register had a problem. Originally, the cash register has been working normally, but when it was turned on in the morning, it suddenly found that the display color was not normal, and it seemed that the display lacked a color. According to Xiaobian's experience, this is most likely caused by the bending of the display connector pins. Customers can try to unlock the VGA cable of the monitor, use the tweezers to correct the curved stitches, and then see if the monitor color returns to normal.
(2) color cast
Most of the displays of electronic cash registers sold by many manufacturers appear reddish or yellowish. After the simple degaussing, it can't solve the problem. Only the recycling silver machine manufacturer will send it for repair. However, some customers have purchased it for a while, and the corner color suddenly returns to normal. Here, Jiawei Shi Xiaobian reminds everyone to pay attention to the display color display when buying POS cash register, especially the corner is enough color cast.
(3) shaking
The POS cash register display is shaking, especially after installing the XP operating system. This kind of problem may be solved after reinstalling the driver, but it is not absolute! It may also be caused by the workmanship of the LCD screen. The cash register manufacturer may also repair it badly, and can only change the LCD screen again. So if you find this problem when you buy a POS cash register, it is best not to buy it.
(4) black, yellow
The display of the cash register is not normal in the middle part, and there is also a case where the color on the left side is dark. This is related to the quality of the picture tube used by the cash register manufacturer. It is likely to be the old picture tube. It is recommended that you do not choose such products. A poor quality cash register monitor can be uncomfortable for a long time.
(5) Ghosting
If the cash register display is ghosted, the image will be noticeably blurred. Generally, this situation is caused by internal circuit problems of the display, and may also be caused by moisture in the cash register display. If there is such a problem with the cash register after purchase, you can send it back to the cash register manufacturer for repair.
