Q:LCD color occasionally slants red
The monitor should be VGA signal cable is not good due to loose contact, DVI will be pulled out and inserted again, the lock can also display itself or graphics is not stable, and will also display other hosts to distinguish between connected fault location.
Q:How do you see the quality of LCD?
Hello, you said 2000:15000:18000:1 refers to the contrast, this is a parameter to measure the quality of the LCD screen, the definition of contrast is brightness / white screen black screen, generally the higher the contrast, the display will be better in some senseSelect several important parameters of lcd:1. brightness2. contrast3. colors,If you are 16.7M and 16.2M, we must give priority to the 16.7M, although it looks just a little bit, but is actually a lot worse, 16.2M is the use of some technology in static state can be achieved so much, but the movie actually only 262K color, a lot of difference4., if you play more dynamic games, then the reaction speed of liquid crystal also depends on the slow, there will be a dragIn addition what perspective ah what their look on the line, by the way check what the dead
Q:PHILPS 23 inch LCD is always black screen?
Re update the problem host video card driver, resetting the resolution and refresh frequency.
Q:Can the lens cleaning liquid clean the LCD?
The liquid crystal surface is a film, so you must make sure that the cleaning solution will corrode the plastic!
Q:PHILPS LCD has snowflakes
When the monitor shows snow, check it according to the following steps:1) try to restore the display factory settingsPress the button on the monitor (OSD menu) to find the restore factory settings, click on the confirmation of the existence of the fault.2) confirm whether the contact of the monitor line is in good condition and whether the connection line is damaged or notMake sure the connection is secure and replace the wire to confirm that the monitor is still working.3) make sure the video card driver is abnormalTry reinstalling or updating the video card driver to see if the display fault is still4) if the above item does not solve the fault, replace a monitor to have a look. If the change after the failure is still, that is the graphics card hardware problems, at this point the need to repair the video card.

The clock frequency of the LCD (liquid crystal display) itself is difficult to keep in full sync with the clock frequency of the analog input signal;Especially in the simulation of synchronous signal frequency changing; if the LCD synchronization circuit, transmission line and synchronous signal connections and graphics problems of short circuit, poor contact, and therefore can not maintain the necessary synchronization, there will be "Huaping" abnormal start;General failure point:1 、 interface pin;2, transmission cable;3. Synchronous circuits are generally semi variable resistors that are dirty or of poor quality;After reversing the display, you can temporarily eliminate the fault phenomenon, indicating the existence of poor contact LCD problems, and the above three, the most vulnerable to such failures are first, second, please Louzhu carefully investigated.
