I tried out progressive component on a Z1 today via a Pioneer 737. The picture was wonderful.

BUT there were some faint but fat horizontal bands on the left side of the picture. They only stretched about an 1/8th of the way across but were a little distracting. They weren't there on an interlaced component or s-video feed, weird?!.

It could be my Pioneer or the Z1??? Anyone else noticed anything else like this??

Thanks in advance.

I would first try another DVD player and see if the problem persists, or connect your DVD player to another progressive-capable display.

Hi,


I have noticed very faint banding on the Z1, running from all sources, not enought to bother me, but it is there if you look for it.

I saw very faint vertical banding as well. This was more noticable and seemed worst on red scenes, thick horizontal bands. Are you seeing these Nick??

I havent noticed any faint bands on mine at all. If its there on all sources, swap for a new one. I dont think thats normal. Did you do the obvious and check all your settings to be sure nothing is out of whack.

Well, I guess you won't be able to recommend any projector since every single consumer grade projector on this planet has one problem or another.:)


I'd say the problem being discussed sounds like an issue with that specific projector, not the model itself. And if it is vertical banding being discussed well, most LCDs have it.

Just to clarify things, vertical banding is a non-issue imho on this pj, it's practically non-existant.

We tried the Z1 in question today with a laptop (powerstrip/dvd etc ), wow!

As previously stated the only "fault" I can find is with progressive component from a Pioneer 737, occasional faint horizontal bands on the r.side of the picture ( worst on red scenes )

All other inputs, interlaced component, s-video,vga no problems to report.

I wanted to see if this was a common phenomenon as I'm wondering if my dvd player is at fault??

I had a little vertical banding from time to time as well on a HTPC (70hz). After adapting the front porch, back porch, sync width and refresh rate (60hz) with powerstrip the banding was gone, subtitles razorsharp and a very fluid image.

If you want maximum quality go for HTPC. Make sure you run the pc at the same resolution as the projector. So i think that banding problems on the Z1 are due to the source for a great deal.

Is the banding the gaps between pixels on the display?. If I look real close on my television I can see gaps too. I can live with this as I watch tv from great distance. Will I see bands from 14 feet on a projector? :(

Did you try the Horizontal Size adjustment (or whatever they call it in this menu)? It's actually a synch adjustment and might be causing banding, though it's usually evenly repeated across the entire screen.
