"Un-official" InFocus 5700 Owners Thread - Page 11

What do you mean by the Denon´s cause ringing and edge enhancement..I thought the Denons were among the best in the business? And I also thought my older Pio 737 had a bad ringing problem.

A sharpness or luma detail enhancement control causes ringing

A digital noise filter, or mpeg noise reduction causes smearing.

First thing I do is turn off all those "enhancements" - but often these controls are well hidden or do not exist.

This is why I prefer 480i - since I know the Faroudja controls on the projector do exist.

Are these artifacts something that the Secrets test´s miss?
I would have thought the "enhancers" would be turned off in the DVD player as default?

Secrets reviews are more focused on DVD deinterlacer quality and seeing what scenes they can find to to cause the image to break up.

It has been my experience that enhancers are turned on by default to make things look different at the store. How would one choose a display or player if they all looked the same showing ISF correct video?

Hello,
I accidentally posted this in different forum beforehere it is:

I am using a SP5700 with an Arcam DV79 DVD player connected via HDMI-DVI, and feeding studio RGB video to the projector. Can Bob Williams, or anyone else tell me what the right RGB levels are on the 5700 for studio RGB video via DVI? Also, does anyone know if the 5700 can be forced to accept interlaced video via its DVI input?


krasmuzik recommended searching for DVI and Bob Williams, however all I could find was the RGB settings through DVI for the screenplay 7200. Does anyone have them for the SP5700 ?

Thanks,
George

Hate to inform you guys - but the MSRP dropped to $3499. Time to switch forums!

I'll ask the mods to move the thread!

When I use 1080i with my infocus 5700, the picture wobbles/vibrates... anyone else have this problem?

Not me.

Do you have a 3910 and 5700 and 1080i works fine? Tried it for PAL also?

Sorry, I don't know what a 3910 is, and I have no PAL sources.

All you said was "When I use 1080i with my infocus 5700, the picture wobbles/vibrates... anyone else have this problem?"

Sorry about that. I forgot to mention I have a Denon 3910, and it´s set to 3910. So the question should have been..

When I use 1080i on my Denon 3910 with my infocus 5700, the picture wobbles/vibrates... anyone else have this problem?

Doesn´t anyone have a 3910 with their 5700? I´d like to know if it´s the player or the display doing the wobbling.

Hello,
I have a screenplay 5700 projector connected to an Arcam DV79 DVD player via HDMI/DVI. I am outputting Studio RGB video from the player (HDMI) and feeding the projector via the DVI input. I have set the color gains at 66 and the color offsets at 39 in the projector. Then I tried to calibrate grayscale using the Digital Video Essentials. My main problem is that while I can see all three stripes in the grayscale pattern when I connect the player to the projector via component, I can only see the two above-black stripes via DVI. Does the fact that I don't see the below-black stripe mean that I am clipping below black information? If this is the case, can this be corrected? The Arcam DV79 player did pass the Blacker-than-Black test in Chris Dearing's Benchmark.

Thanks,
George

glk6655,

That is the whole point to the adjustment is to clip the blacker than black. Otherwise your contrast ratio is lowered for that occasional test DVD that has excursion into the forbidden blacker than black zone. Studio RGB should allow blacker than black to pass if you raise the brightness (offsets) - but the whole purpose is you are calibrating the projector to maximize contrast ratio! Studio RGB is about allowing this headroom/footroom in the interface - but it does not make sense to compromise display contrast/brightness by not clipping what should not be image information.

Just adjust like you would with a player that does not pass blacker than black. Keep the near black bars barely visible.

If your DVD player is correct Studio RGB there should be no need to calibrate the DVI at all.

Hi guys, I posted a new thread in htpc forum, but thought I would give you guys a shot to help me figure this out!

Lost my DVI connection

P4/3.0CGHz
ATI RADEON 9600 256M 8X AGP
InFocus 5700 projector

The other day I was messing with powerstrip and changing resolutions. I had gotten success using a powerstip 1024x576 preconfigured resolution. I changed to a different resolution for whatever reason, i think it was 1400x1080 or something close to that, and all of a sudden it was like someone unplugged the dvi cable from projector. This actually happened to me before when I first had my projector and was running windows media player and clicked on the "visualizaitions - full screen". I was able to use my VGA cable and reboot and the DVI connection came back on that one time before.

But now, i have tried everything i can think of. I switched over to VGA and changed the resolution back to the last good one and no DVI. I then rebooted, no DVI. I then removed powerstrip and used 1024x768, no DVI. I then did a system restore from week before, no DVI. I am really frustrated.

Please help me think of what it could possibly be.

Hello,

I am noticing a green tint on my 5700 lately (connected via HDMI/DVI to an Arcam DV79 DVD player). My lamb has only 100 hours on it and the dealer offered to give me a lamb replacement. Do you thing this is a lamb related problem that can be corrected with a new lamb?

Try changing the color space - some reports of upconverting DVD players using HD instead of SD color space which will result in green push.

Or in the RGB gain menu - take green gain a few clicks down.

Every lamp has the problem that in the first 10% of life it will be drained of red. So yes a new lamp will restore the reds - but then you are right back where you started before too long.

Is this a sign that the 5700 is reaching maturity or losing popularity or both? There appears to be less and less posting on this particular machine.

Maybe the product is so well built that virtually nothing goes wrong and there is nothing to complain about.

Certainly into EOL phase after being out 15 months! That is the way the forum is - always excited about new stuff.

Hello krasmuzik,

Thanks for all the good advice.

I am sure the color space is correct. Even though my DVD player can output either YUV or RGB video via HDMI, when the player communicates with the projector it defaults to RGB, since I believe this is the only one the 5700 supports over DVI.

You say that every lamp will be drained of red in the first 10% of its life. Is this universal, or something to do with Infocus? Also, is the green tint going to get progressively worse as the lamp ages? After 100 hours it is most evident in skin tones, however to be honest the effect is subtle. Nevertheless, if it's going to get worse I guess it would be pretty nasty by the time the lamp reaches the end of its life (~2000 hours).

Thanks,
George

Nope - just the nature of lamps. JVC Dila used to use the Xenon lamps which are native 6500K and hold it well thru life - but they still drain blue instead of red (and eye is blue insensitive)

I wait for 10% lamp life before calibrating to wait for the lamp to burn-in.

If it is RGB not YUV then the color space of SD vs. HD. is made in the player and cannot be changed on the projector. Any player settings for it?

Infocus does like to stretch D65 over to green just to make it brighter. You are using 6500K with white peaking 0 correct?

Maybe you can find an ISF tech that will work hourly - I find it only takes an hour or two on Infocus since they are so close to begin with - thus I can charge much less than ISF standard fee.

Hi All,
Hopefully this isn't a lame question, but what actually happens when you adjust the brightness (besides the image getting brighter ) on the 5700? Why I ask is that my 5700 is 12 months old (350 hours) and if I calibrate it with DVE I need to set the brightness to 66 to for the brightness calibration patterns. Does this brightness level sound a bit high or is this a function of the signal being send from the DVD player (Denon 2900)? Does the brightness of the lamp actually change or is this a function of the signal the projector receives? Other that this curiosity, I'm extremely happy with my 5700 / 2900 combo.

cheers,
Stephen

My 5700 is now 8 months old and it has 1000 wonderful hours on it (we use it alot, pretty much every evening). I haven't noticed much degradation in the picture or brightness, but I know that time will come probably before the end of this calendar year. I want to order my replacement bulb now, so that I won't miss any time if the current bulb should fail before 2000hrs.

Do any of you have recommendations for bulb dealers? Looking for lowest cost obviously.

Try setting your black level enhancement off on the Denon. The Infocus projectors are expecting 7.5IRE - if you have good voltages I have rarely moved far from 50. I prefer to find the settings on the DVD player resulting in fewer adjustments.

If you are running progressive rather than interlaced - then your player is probably adding some gamma causing to raise brightness to compensate.

The proper brightness setting is when DVE black bars test has the BTB and blackground the same - they are not dithering, but your near black bars are barely dithering. Turn up the gamma to help you see near black better (just put it back to where you like it). You have to be up close to the screen to best see the dithering - usually green, sometimes blue, rarely red.

I assume you are using component - the procedure is different for DVI.

BTW brightness is a video black level control - do not confuse it with a lamp brightness control!

I have actually had one customer ask if he qualifies for a frequent buyer plan - six months already 2000. I do cut them deals on recalibrating with new lamps.

Only your local authorized screen player dealer can sell you a lamp - but Infocus Online does sell them under a different part number. Do your research and you will figure out what business projector is the same lamp.

Hi Krasmuzik,
Thanks for the excellent advice. Some more information I should of added is that I'm in PAL land (Australia) does this make a difference with the 7.5IRE and turning the black level on or off on the 2900? I have the Denon 2900 outputing a PAL Progressive 576P signal to the 5700. I also have the GAMMA set to 'Film 2' when calibrating with DVE, should I leave the 5700 on the 'Film 2' when calibrating with DVE? Once again, thanks for all the advice.

Regards,
Stephen

Not sure if PAL models has different firmware for defaults. Try it both ways and see which gets you closer to 50. The less adjustment the better! PAL is supposed to be 0IRE - but you are rather high on your brightness at 66 so maybe it is expecting 7.5IRE

Gamma does not impact calibration - just makes it easier to see dark black while calibrating. Just set it back to your preference when done!

10-4. I guess I could have asked who has the best deal on a Knoll HD177 replacement bulb since it's just a rebadged IF-5700.

Hi Krasmuzik,
This turned out to be the case, I set the black level on the Denon to 7.5IRE (instead of the PAL default of 0IRE). I then recalibrated with DVE and got a brightness level of 49! So the 5700 was expecting a black level of 7.5IRE regardless of whether it was being feed a PAL signal. As you also said it makes sense to adjust things at the source instead of 'pumping' up the brightness on the projector to compensate.

Regards & thanks,
Stephen

I noticed there´s a new firmware out for the 5700, has anyone installed it? How is that done anyway.. do I need a special cable with M1 at on end and USB on the other.. and then what?
