nView z310

Hi there,

I've been reading this forum for a few days now, and I am now starting to think about purchasing a LCD panel.

I have found a NView Graph X Z310 Projection Panel which I am interested in purchasing. Does anyone know anything about this panel? I read a page which said that it had 1024x768 resolution. Is this true? Also, can someone tell me what type of input it accepts?

Thanks in advance for any help.

This panel has 1024x768 resolution. It only accepts VGA input, and if you do some searching, others have said it is too slow for watching video.

(I know where you found the panel

if it were faster, I would pick it up in a second.)

Ok, thanks. Glad I didn't bid then.

Who said that? The post I read said it worked fine, but just a little noisy. Some other dude had problems with his (Z315) but I thought that way explained away as being macrovision...

PlasmaSMP · 2002-09-04 4:51 pm

What?? With only 1.4 million colors, and being "perpetually slow" there IS a reason why that panel only went for $80 on ebay...

Tinker · 2002-09-04 9:28 pm

$80.! I guess so. I think your right there PlasmaSMP! If it was better it would have went for alot more especially at that res. I've seen the 640x480 16bit panels that were faster and only vga go for near $200 already and sub $150...

PlasmaSMP · 2002-09-05 2:12 am

Yeah, the last QA-2500 went for $500! :bigeyes:

WoW

They can have it at that price.

Hecksomtimes you can get a real projector with a dead bulb for around $500 change the light source and make that panel look like junk.

PlasmaSMP · 2002-09-05 7:21 am

true. But you have to admit, that panel would be lotsa' fun. Not to mention the great bragging rights you would aquire on this forum...

Tinker · 2002-09-05 8:48 am

Yes, you would def. have braging rights, and prob. alot of jealous DIY projector fans too!

Help with the Z310

As you might have noticed, I am the one who won the auction for the aforementioned nView Z310. I am wondering if someone might help me out with it. It looks to be in really nice shape and came with lots of accessories (perhaps *all* of them... manual, cables, adaptors, remote, carrying case, etc.)

It powers up fine and displays the nView logo, but I cannot get a picture onto it from my GeForce 2 Ti's VGA output. I believe I am using the correct cable as explained in the manual, but the little backlit LCD always says "INPUT: NO VIDEO" and of course the logo remains on the screen.

I tried a multitude of other cables and adaptors, all to no avail. Might this have something to do with the "new" VGA using all 15 pins whereas I believe the "old" VGA had pin 9 missing and perhaps also pin 15 missing? Do I need some sort of adaptor to convert my "new" VGA back to "old" VGA?

I also tried many different screen resolutions and color depths from my vid card. Nothing seems to work - please help!

Tinker · 2002-09-19 9:05 pm

Hmm, new or old vga it should make no difference. You see the G2 G3 etc. is able to run older mon. its backward compatable to a extent. Atleast it goes that far back anyhow. I would'nt plug into a monochrome mon. though. So it should support that panel fine. Does your G2 ti have s-video out?

Schmanthony · 2002-09-20 6:00 am

My GeForce 2 Ti does not have an s-video out, nor does the nView Z310 have s-video (or composite) inputs. I'm going to try getting it to work on a Mac tomorrow I think... anyone else have any other ideas for me?

PlasmaSMP · 2002-09-20 7:21 am

Try setting your display to 1024x768 @ 60hz, then plug in your projector. It should work at this setting. If not, contact the guy you bought it from.

Oh, and when you do get it running, please tell us how bad the motion blur is on it... I would be interested in hearing whether it is fast enough to display DVD's @ 24fps.

Tinker · 2002-09-20 8:46 am

By the way. I dont think all 15 pins are used anyhow. I think it is like 9 pins that are actually being used. The others even if there are not being used i.e. they are not soldered to any wires. Please correct me if I'm wrong. But I'm pretty sure.

Schmanthony · 2002-09-20 12:01 pm

Tinker,

Go here:
http://www.l-com.com/content/ResourceCenter/Tutorials/tutorialsmain.jsp

and click the "video cabling" link (be sure JavaScript is turned on)

You will see that Standard VGA uses all 15 pins *except* pin 9 and pin 15. VGA with DDC (Data Display Channel) uses pin 9 and 15 for "communication between a monitor and a host system," whatever that means.

I will try the 60Hz thing... right now I have the GeForce's refresh set to "optimal," which I think sets it as high as possible. Maybe that's what's screwing it up.

Schmanthony · 2002-09-20 12:18 pm

Thanks PlasmaSMP, the 60Hz thing worked! Since I was just swapping the VGA cable right from my 21" Trinitron monitor to the panel, I'm sure the panel couldn't copy with the same refresh rate.

I don't have my OHP yet, and the sun isn't even up yet - so the only thing I could do was to hold the panel up to the incandescent light on the ceiling while I was running the 20MB "Spiderman" preview double-sized to nearly full screen. Not a very good test, but here are my initial impressions about motion blur...

When there is not much motion the picture is fine - I do not think the 1.4 M colors limitation will be significant.

When there is a lot of motion I don't see any "blur," so to speak, but I do see that the picture breaks down to some extent into vertical lines. They look like real lo-res vertical scan lines, if that makes any sense. Anyone ever seen this before? Is this "motion blur?"

Only further testing will tell if the same problem comes up with an OHP, a line doubler, and a DVD source.

Hu, I never knew that. Learn somthing every day huh! I guess I never really needed to know though either.

Great to hear you got it working!

PlasmaSMP · 2002-09-21 9:23 am

Your welcome.

As for the motion blur. If it is like most LCDs that I have seen. (like the RAD 5) when something moves fast across the screen, it leaves a streaking blur pattern, like when you turn on the mouse trail.

Try watching your panel and moving the mouse around fast. Then compare it with your CRT monitor to make sure you don't start to "see" problems that aren't really there.

Tinker · 2002-09-21 9:59 am

Those lines arent from motion blur I dont hink. They could be somthing else. My psone panel/projector doesnt do that. But then its prob. alot newer lcd tech too. At any rate doing the comparison that PlasmaSMP said. What I really think is happening is your used to looking at high res. crt. Then you are looking at 640x480 which is kinda pixely and you can see lines easier during fast motion. Turn your crt mon to 640x480 and see how the video looks then to compare to the low res. panel. Thats what I would do.
