Hi all!
I have just recently become a happy owner of a JVC DLA-G10E after some years with my old CRT, a Sony VPH-1270QM. I've tried to consume a lot of tweaking knowledge from these forums, but there are some questions I'd like to ask. I have a PC on loan which I'm using with the D-ILA. It's a P3 750, 768MB ram, Matrox G400, Hauppauge WinTV PCI, SB Live etc. I have Dilard for tweaking, but haven't really had time to use it yet. I've downloaded the latest Powerstrip and Dscaler. DirectX is 7a, PowerDVD is 2.55 and G400 drivers about a year old.
First I used Powerstrip to make the 1360x1024 resolution. I noticed that this was set for about 72Hz refresh, so I threw in my region 1 Gladiator and was ready to let my jaw drop. And it did. http://www.avsforum.com/ubb/smile.gif
I guess I'm going to get more of those experiences after I've done the tweaking with Dilard and got myself a new PC for DVD playback and Dscaling. After some Gladiator I tried Dscaler for the first time and was surprised again to see how well it really works. Thank you all DScaler developers! Then I realized that I really needed to do some tweaking too. I downloaded Mark Rejhons D-ILA Test Pattern and started going through tracking and phase. However I never got satisfying results. Looking closely to the picture, whenever I was getting really close with phase, I would get some thin vertical blue stripes in some parts of the picture. In DScaler they were even more visible in dark parts of scenes. I tried to get rid of them, but when these blue stripes started fading then the actual phase setting was completely wrong otherwise.
More searching in the archives revealed this this article which gave me more parameter values to place in Powerstrip. These values seemed to work on M. Rejhons patterns, although it seemed like my phase tended to crawl a little, but after a while I found a phase setting which seemed to do the trick. However, when I restarted DScaler I got the stripes again.
Then I went back to the original settings of Powerstrip, because I hadn't noticed the stripes with Gladiator, although I wasn't that perceptive at that point. This time the stripes were hardly noticeable, but still there. However M. Rejhons test images showed that I was looking at complete garbage, which was funny because I honestly thought that the picture from Dscaler was now better than ever.
Other strange facts were that the JVC manual states that SXGA3 is intended for 75,1 Hz refresh and Powerstrip was saying near 72Hz. Also the above linked web page says that one should prefer 75Hz. Does 75Hz in this case prefer PAL DVDs PQ wise, or does it matter with D-ILA?
Has anyone else seen these thin blue stripes? What would be the way to get rid of them? Tweak all parameters to death? In the end I don't even want to do all tweaking yet, because I'm getting a new PC with different hardware sometime in the near future.
Any help is greatly appreciated and I'd like to thank everyone for their efforts in making these forums so ample in information.
Thank you!
