Viewsonic Pro8100 1080p Projector - Page 175

No dice, these are used to eliminate ground hum.. that's a low level hum coming from speakers... I use these in my PA system, they won't help you on banding...

I bought mine from J&R through Amazon. It has a Jan 2010 build date and I am approching 70 hours and still no banding. I threw in Star Trek last night at 11:00pm just to see what it looked like and ended up watching the whole movie. . WOW this projector is just amazing. Best purchase I have made in years.

Looks like J&R dropped the price down to $1099 which is crazy cheap but also a sign that things are coming to an end. It looks like once the current stock is sold that will be the end of it. I will be ordering one more at that price, just to good to pass up.

Mine is from TD with a 01/10 build date and will have 100 hours soon. NO banding and it's been updated to 2.5 firmware. Very grateful for this, I usually get the problem ones. Signals are running from my Onkyo A/V through a Monoprice 4/1 HDMI splitter over 50' of 24awg HDMI (also Monoprice).Had a scare the other night while watching "Monsters & Aliens"--for the grandkids, ya see......except they weren't here. LOL Anyway, I look up at the screen and lo and behold........Horizontal Banding! DAMN! Then I realize it was a scene in the movie that was depicting a TV broadcast and the "banding" was in the movie itself.
Sorry so many folks are continuing to have this issue. Sure hope a cure is found. It's a great projector and I love mine!

Good question, I'd like to know the answer to that myself. Should the generics be avoided? Being paranoid, I'd like to have a spare and if the OEM should go I'll be ready. Did that with my Mitz 73" DLP TV a year and a half ago and the original lamp is still going strong.

I bought a spare lamp some time ago... just make sure it's a real VS lamp.. there are clone lamps out there.. they are the cheap ones.. a VS lamp is going to run around $320.00... burn it for a few hours after you get it to make sure it does not pop. You're good to go...

Okay here are my settings. I want to thank Dark Rider for graciously taking his time out to calibrate my pj few weeks ago. I watched 3 hours of Planet Earth blu-ray last night and felt really satisfied. Watching in Normal lamp mode makes the picture popped !!

Thanks Dark Rider. Switching back to user 2.2 got rid of the posterization. I'll keep it at 2.2 for now as I am satisfied with the picture..a little brighter too.

I had to modify mine a little as the front mounting points are rather far apart. Approx. 9.5"

Haven't bought one yet but will go w/ Uncle Willie's advice when I do.

Ranger THANX alot and THANX u darkrider

I believe someone reported that they had success using the XP mode in W7.

Might check the transformer you're planning on getting as it might still have a common ground circuit which a true isolation xfmr won't have.

I ordered it primarily to test if input voltage has any effect to HB. Thought that isolation is just nice bonus. But thanks for letting me know, I'll check that.

If input voltage has an effect on HB, then we need to collect some data from the folks w/ recent purchases to see what their house line voltage is running.

Yes, I had it without upgrading. I was seeing it mostly in light ares specially on faces. I kept telling my self although the picture overall looked great, human faces sometimes looked wost than my 720p Benq 8700 when playing HD sources.
This new one looks much better so far.

Haven't tried it yet. Will do that when I have enough time.

Glad you're enjoying it Ranger! The gamma tracks very linear at the 2.2 user setting so you won't have any trouble and it won't impact your overall color/grayscale calibration. The most noticeable thing, as you mentioned, is that it will be a bit brighter since the 2.2 setting tracks closer to a 2.1 true gamma setting. 2.1 looks washed out on some displays, but the Pro8100 has so much color punch, that it looks darn good on this pj. Anything lower than 2.2 (darker) in the 0-30 ire range starts to crush blacks, but does improve black levels some. The compromise is not worth it IMO and the difference between true 2.2 and 2.1 is negligible at best in this range.


No problem bouda! Ranger's adc calibration was very close to Meret's, so my assumption is that his settings will look very good for anyone running a new build date Pro8100 with a matte 1.0/1.1 gain screen. I can certainly confirm that they looked very good on his unit! If you're still searching for something with a bit more pop for your older build date, try my most recent Eco mode settings and up the basic saturation to between 52-54. This will bring some of the saturation back, but using the 3D CMS settings to equalize the intensity, which will make it look much more natural and still give it a LOT of pop!


I haven't noticed any correlation in the firmware upgrade and the horizontal banding. I would say that it was just coincidence if someone experienced a problem that was more noticeable afterwards. Folks are definitely on the right track with isolation transformers. It's an electrical input sensitivity issue of some sort and is worth trying to fix IMO. It's a shame that VS won't step up and resolve it, but as others have suggested, it could be that they've had enough and are just looking for a path out. The Pro8100 is such an amazing projector for the $$ though. I would hate for this to be VS' last hurrah! If it does, I will likely hold on to mine until LED becomes mainstream and will likely end up going LCOS/SXRD if JVC or Sony can get their sharpness levels up to my liking.

First, I just wanted to say thank you to all the quality contributors to this thread. It was a great source of info to me when looking at projectors and ultimately helped me decide on a Pro8100 last fall. I love my Viewsonic; it's my first projector, and I am working on finishing my basement and building a nice big screen to complement it. Unfortunately the only time I can use it is when the littlest ones are in bed and aren't going to knock it off the small table in our living room.

What made me decide to finally post here is this:

I came home from work Tuesday night to some frantic calls from my wife in our room. The projector had been hidden underneath a mounted bookshelf in our room that is relatively full. Said shelf fell off the wall, dropped about 4 inches and landed on the top of the Pro8100. The shelf was so heavy my wife couldn't budge it without removing most of the books.

It was a very tense 10 minutes while I extricated the PJ, inspected it for damage and ran it out to the living room to test it.....

IT STILL WORKS! Actually it's not really even scratched.

Since I'm sure none of you are willing to attempt to recreate it for scientific purposes, I'll just assume the outcome is due primarily to the build quality of this huge monstrosity. Well done, Viewsonic!

Dark Rider i tried ur settings they are a so good , natural colors and natural image what i add is the extra sharpness 53 and detail enhancement to 5. and at animation i increase saturation to 50+ but what i like about ranger are the gamma settings because i have the 1.0 gain screen and i think sensor should receive different readings at higher gain screen. all the ways thanx for ur extra effort at calibrating this beast

thats a new drop at the price brand new for : 999$ at :

VS must be dumping them.

Well, hour 78 and guess what. VERTICAL BANDING. Bad too. I will try a few things to get rid of it and will post the results. I thought I had a good one too.

Ok, shut down the projector and let it cool down. I unplugged it for about 20 min and replaced the bulb with a aftermarket that I purchased as a backup so I could test it. Turned on the projector and the banding was still there. I have had it on for about 30 minuets and the banding has almost completely faded off. I really don't know what to make of it.

By the way the aftermarket bulb so far looks perfect.

This banding issue has me concerned now. I will probobly contact VS next wekk for a replacement if it continues. I have no desire to change to a different brand as I love the color and sharpness of this VS, I just hope this band issue can be resolved for all of us.

Vertical banding? As in lines running up and down the screen? Don't worry, the majority of us have that and it's a non issue. Just buy a timer for your outlet that cuts power to the projector for 3 hrs every night. I've been doing it since last fall and it hasn't returned. Do not return it if you only have vertical, not horizontal banding...it's a $5 fix.

Horizontal banding, OTOH, is more problematic and would require a return.

I recall someone with HB was going to try using a two prong adapter. Would be interesting to hear if that had any effect. Same w/ using an isolation transformer.

I for sure (this time) have one on the way. I will post my thoughts next week. Can't wait.

I went to directron and put one in my cart just for chuckles--wanted to see what they charged for shipping. It then tells you that the VS Pro8100 is not currently available. Anybody ever order anything from this place? Never heard of 'em.
