LCD display Font Hollow what to do

To solve the problem of LCD Font hollow, the first thing is to check whether the resolution of the LCD is correctly set. The LCD will have an optimal resolution, like a 19-inch widescreen LCD is 1440*900 (partly 1680*1050), and a 22-inch widescreen LCD is 1680*1050, and font hollow occurs when the user sets a resolution that is not the optimal resolution.

If the user cannot find the best resolution for the LCD in the tuning option, the driver for the video card needs to be installed first. This also explains why most users who find the font hollow phenomenon occur after the video card has been replaced. Therefore, if you find a problem with the hollow of the LCD, check that the system resolution is set to the optimal resolution, and if you do not find the optimal resolution in the adjustment, you must first properly install the driver for the video card (including the integrated motherboard).

If the resolution is determined to be correctly set, there will still be the phenomenon of the word hollow, then you need the user to adjust the LCD monitor. The method is very simple, is directly on the LCD OSD menu on the "Auto" button (some LCD is through the combination of keys to achieve the Auto button), the role is to let the LCD automatically adjust to make the text display more sharp. Of course, this is only useful for analog signals (VGA), if the user is using a DVI signal line, then its role is not too big. If the user does not have the "AUTO" button on the LCD OSD button, it needs to be manually adjusted, generally adjust the "pixel frequency (Pixel Clock)" and "phase adjustment (Phase)" Two options, which can be found in the LCD adjustment menu.

Of course, in addition to the resolution and automatic adjustment, some LCD display Font hollow is really because of LCD IC drive circuit design or workmanship defects as well as aging, but also may be integrated motherboard electromagnetic shielding do not good, this in some inexpensive products appear on the probability is relatively large (in fact also very rare), For the implementation of the previous operation has no effect, it can only contact the LCD display after the sale and the manufacturer.
