Some of you may have seen on other threads that i was having trouble with this H56 of mine. first got it replaced diredy with optoma, but still had the same problems. BUT what i thought were problems was in fact mostly my inexperence with projectors.(as this is my first one) coming from plasma i took a few things for granted like a progressive signal. u feed it to the plasma and jobs a good un. but with the H56 its not quite the case. so i fed it a signal and it looked like it was only filling 3 quarters of the screen and there was a horrble red tinge to everything etc. what i didnt know was i needed to adjust the frequencys to get thing perfect. so set frequency, this stretches the pic across to fit the screen. (pal prog issue sorted) then i adjusted the vertical (NTSC problem sorted) then i had to change colour balance, and reduce red contrast and red brightness.(crapy red problem gone. i should of guest this earlier but didnt realize you can set colours different for interlaced and progressive as well as ntsc and pal) calibrated everything with DVE for pal stuff and the pic is now excellent. the A11 i have is doing a much better job at deinterlacing than the sil504 as it corrects edge enhancement and chroma issues etc.(its suprising how much more it does than just deinterlace) the pic is truly brilliant for such a low res PJ(and cheap) So i guess what im saying is as a newbie, patience has realy paid off. I have been fed alot of BS at times some from optoma(with good intentions) some from others but persistace has paid off.( a good side is my knowlege has increased one hell of alot, im a noob no more. a thanx goes to Roy stonebank at optoma for realy wanting to help. and special thanx to Justin Halls of optoma for nailing the problem and taking the time to explain detailed tech. So all works fantastic...........Shame im going to upgrade now just as i get it sorted im going to sell it.
