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\015\012my old man is an electronics engineer, rather than be without a monitor\015\012since 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\015\012all the the cables going to the power supply and dvi port assembly,\015\012undo two screws pull down and out you wil now be looking behind the dvi\015\012port and be holding a metal module that contails power supply and dvi-\015\012and vga port.

3.you will notice a piece of brass foil joining\015\012the earths on your dvi and vga cable this is the problem creating an\015\012"earth loop" as both vga and dvi ports are earthed to the metal casing\015\012this extra earth is causing the problem introducing noise.

3.carefully\015\012unwrap the brass foil from the two cables and seperate, insualte cables\015\012with electrical tape. (wrap around each one seperately they should now\015\012be indiivdual cables)

4.you will notice a silver spring type peice of metal on the assembly that pushes against the
main\015\012body of the unit when re-assembled. scratch the metal with a\015\012screwdriver where this peice pushes so you get a good connection when\015\012you reassemble it, do not touch as finger grease could screw up the\015\012connection. (this step is not vital just a good thing to do why your in\015\012there to make sure the the unit is properly earthed)


enjoy,\015\012fixed mine and was quite easy, take care with the plastic latches they\015\012are tight - ensure you remove all 5 screws, to see the fifth easily the\015\012monitor stand must be removed (two screws then stand slides out from\015\012rear of case)

good luck
