    I have a vp201b, which uses an LG/Philips LM201U04 as its panel.

    I am getting dancing pink and green pixels - they show up when different colors are being displayed. If the color is black, I see green dancing pixels / snow. If the color is light grey or white, I see pink ones.

    Nobody seems to know anything about this or how I could go about fixing it even if I was comfortable soldering connections on the panel itself.

    I replaced the backlight inverter this morning and found out that this is NOT the root of the problem with "dancing pixel" issues.

    I have the same problem w/ 2 of these monitors. Good to hear is not the back-light inverter, although that would not have been my first guess. I've noticed with mine that you can "hit" it gently and it will go away until it is moved/"hit" again. which would lead me to belive its a bad soldier joint somewhere, just not sure where that would be.

Your Video Card´s DVI output is probably damaged. You will have to replace your video card , or use only the VGA output.

When turning on my computer I get no picture on my screen. I have checked all conections and made sure that they are all properly conected. What needs too be done?


Was your monitor previously working? Is your monitor set to receive input from the cable its connected to? There are different inputs for monitors usually. Make sure your monitor is set to receive input from the cable (vga, hdmi, DVI, ect.). If your monitor is very old, it may just be that's it's giving out. If your monitor is new, it may be that it wasn't working to begin with. If its not the connectors, then the monitor may just not be working.

Dear sir i have a apple cinema display m8149 lcd.i have loss my apple system(cpu) and want to run apple tft with other cpu (intel dvi and vga) tel me the how will conection or explane me where are RGB...


You can run that monitor from a DVI connection but you would need to get an adapter from DVI to ADC and that supplies power to the monitor. DrBott makes an adapter like this called the DVIator (http://www.dviator.com/) that should work for you if you other CPU has DVI out.

There is both an analog and digital setting on your monitor settings. Bring up the monitor settings and toggle between the digital and analog settings until you get a signal.

When dvi plug is used screen gets funny bright colored lines


FIX for design fault of ASUS VW222u Problems with monitor using dvi while vga works fine.

my ASUS VW222u had the same problem many are reporting after about 8 months
with developing colored "noise" onscreen or dancing red pixels while using dvi but vga is fine.

luckily my old man is an electronics engineer, rather than be without a monitor since vga still works fine we decided to have a look.

we worked out the problem. note: this is a fix for the random picture noise problem while using dvi port.

If monitor works ok with vga but dvi has noise then this fix should work for you.

1.open monitor (will void warrenty)
2.unplug all the the cables going to the power supply and dvi port assembly, undo two screws pull down and out you wil now be looking behind the dvi port and be holding a metal module that contails power supply and dvi- and vga port.

3.you will notice a piece of brass foil joining the earths on your dvi and vga cable this is the problem creating an "earth loop" as both vga and dvi ports are earthed to the metal casing this extra earth is causing the problem introducing noise.

3.carefully unwrap the brass foil from the two cables and seperate, insualte cables with electrical tape. (wrap around each one seperately they should now be indiivdual cables)

4.you will notice a silver spring type peice of metal on the assembly that pushes against the
main body of the unit when re-assembled. scratch the metal with a screwdriver where this peice pushes so you get a good connection when you reassemble it, do not touch as finger grease could screw up the connection. (this step is not vital just a good thing to do why your in there to make sure the the unit is properly earthed)

4.re-assemble


enjoy, fixed mine and was quite easy, take care with the plastic latches they are tight - ensure you remove all 5 screws, to see the fifth easily the monitor stand must be removed (two screws then stand slides out from rear of case)

good luck

Monitor Problem


1. Try using a different media player like k-lite windows media player classic or GOM player.

2. Is the lcd set at it's native resolution ? Set it to native resolution.

3. Has the driver for the lcd been installed and does it show up properly in device manager ? Install the lcd driver if applicable.

4. What are your system's specs, especially graphic card ?

5. Has the latest graphic card drivers been installed ? Install latest drivers.

6. Does using VGA or DVI make any difference ?

7. You would've probably already checked windows media player settings.

Hopefully some of these will solve the problem.
