I am looking to exchange my old Samsung 32A656 LCD with a 42 LED , hopefuly passive 3D. Since passive & 42" only are available on LG & Philips (at least in my country) i have stumbled on thesee two models: LG 42LM620S & Philips 42PFL4307H. The primary use being as PC monitor of course my concerns are input lag, 4:4:4 chorma and motion handling.i found a review of 42LM620S wich states that it has 30ms input lag and support chroma, but somehow i don't trust the input lag test from hdtvtest.co.uk. unfortunately i found no review of Philips 42PFL4307H. if somebody can give me any info regarding the two models as how good they are for PC usage i would be very grateful. thanks in advance.
