i was wondering if anybody out there has ever tried removing the red and green color filters on a sony 12xx? replacing them with clear should increase light output 26%, 700 to 882 lumens. i'm not picky about my reds looking orange or my greens looking yellow but i do expect it would warm the picture up a bunch.

while i'm at it i might as well ask if anyone has tried spray painting the aluminum lense mounts flat black? i painted them on one machine expecting to not see a difference and it helped so much i ended up painting the inside of my 1272 case flat black aswell. i ohnestly can say it increased contrast and reduced that washed out look another 10%.

any comments on removing color filters and painting things flat black?

Color filters? Where are they?

check out curt palme's website about cleaning fungus. The procedure should be similar. However, it's nice to have filters. I don't have any issue with the brightness on my 1272. I used a gamma tool to increase brightness.

I did paint my lense mount as well with flat black paint. I haven't watched at it yet since I just finished mounting the pj to my basement ceiling. I have a thread that shows a picture of the painted lens mounts.

Here is the pic

This technique was shared to me by Sonynut! :D

replacing the colored r&g glycol with clear

v1rtu0s1ty, what are you using to increase gamma? i'm guessing gamma is where the black detail is at and by bumping it up its easier to see shadow detail? it differs from briteness because after messing with gamma you can see shadow detail but still have perfect blacks?

Won't that completely wash out the all the color??

I'm using nvidia-settings utility to increase gamma. My setting is at 2.3 for all 3 channels. Going above that value, picture color quality becomes unacceptable.

it might wash out the color, ive got a bg808s without color filters and its got good enough reds and greens. i just know when you add color philters it takes aproximatly 13% ansi lumens to each tube.

v1rtu0s1ty did you try ajusting your saturation? i'm using a folsom vfc-2200 (ancient i know) and on my barco i run gamma at 3.00 and it forces me to turn the saturation up to 135%.

Did you mean GAIN for the 3 channels? If so, yes. But before I started tweaking it, I modified each voltage for the 3 channels from ~3.5 downto 1.5 using a voltmeter. I changed it using the screen knob(above es focus knobs). I turn it very very very very slowly as if my fingers weren't really moving at all. :D

Oh, I placed a black electrical tape over the SCREEN knobs so that I won't accidentally turn it. :p

on my 1272 ive done curts spacer mod, painted the mounts and inside of case flat black, tried out some pt-65's and hd-8's and the hd-8's that came on it were better which kinda bummed me out. i must have those new all glass hd-8's. maximized the rosters and ajusted the bais and gain. ajusted the lense flaping by making my pj almost level with the middle of the screen... is there anything i'm forgeting about? lol

i'm writing that down on my list

I think that's what I did too! One note, I did ES focus the tubes while the lens were off.

If you look at my signature, Sonynut gave a phenomal online technical support when I was troubleshooting my 1272. :D Check it out! Tons of great information in there!

when i run my 1272 at resolutions higher than 960x1280 it starts to streak and ghost really bad. i made a test resolution on paint brush with one pixel lines and it would resolve 1200x1600 with the lenses removed (really realy low briteness/contrast) have any of you guys tried sending your 1272's anything above 1200x1600? i sent mine 1536x2048 and it still resolves the little dots on my test pattern (max roster) but it has a ghost effect. any ideas about that?

I'm running mine at 1920x1080 72hz interlaced, no issues. Your resolution, 1536x2048, is so friggin high! Can you post a screenshot of how a picture looks like with that resolution?

heres some pics of my dirty basement project. in the near future i'll mount the 1272 to the cieling and take all the junk to the dump(aka auction:D)

I don't see any pictures.

heres some screen shots from museum 720p from the folsom running 720p-59.98

1536x2048 is freakin huge, its blurry if i run it over 50contrast 50 briteness. my screen is 84" diagonaly and the curser is less than 1/2". u can read size 10 font and play halo if you dont mind sitting 3 feet from the screen to read the micro ghost text. someone said to ajust my blanking that might fix the ghosting.
*blank 1536x2048 lol:D

Very nice! I don't see scanlines when running at 1280x720p. I only see scanlines when running at 720x480.

Looks like it's beyond 1272's capability. Are you sure that you have tried this on your 1272? What vertical refresh rate did you use?

are you running max rosters? thats what did it for me, that and the tiny 84" screen. just make sure to feel the tops of the tubes, have your blanking set, and watch your contrast/brite and scan rate.

if you think 1536x2048 is really something i ran my barco graphics 808s at 1920x2560 and it was sharper doing that than the sony doing 1536x2048. my favorite rez (even if the tubes dont pass it) is 1440x1920 and that makes a deciently sharp desktop

60 fps when running 1536x2048 and all other rez except when i run 960x1280 at 75 fps

heres a few more pics, ive got a second 1272 i was going to use these two in a blend but after i got everything together i could only get about 1 fps out of my computer playing grand theft auto resolution was 600x1600 i also tried 1200x3200 and my computer kept freezing. i'm willing to try the blend again someday with a better card than the nv1100 quadro

the way i got my computer to force 1536x2048 was by hooking up my fw900 (24" crt computer monitor) after selecting the desired scan rate i unplug the monitor and plug it into the projector. it does that resolution without panning. when i press page it says 95 for the fh and 59.98 for the fv. 95 is 3 over its max rated 93 i know, but it does it. i'll post a screen shot as soon as i can borrow my rich dads fancy camera again.:D

Nick... resolutions are written with the horizontal number first. So 1280x960, not 960x1280. Sorry... driving me crazy :p.

Perhaps the man prefers portrait mode. Not that there's anything wrong with that... :p

Yep, I had to change my eye orientation too earlier. HAHAHA! But I knew what he meant! :p

what is the width of the projected image? The fonts are clear.

That is an awfully clear pic for 1600x1200.. Only way
I have ever been able to achieve that is to turn my contrast down to like 30-40 and get one horribly dark picture.. even when my 1272 only had 800 hours on it..

Perhaps this is why you are interested in clear glycol for more brightness?

Yes the green and red would be brighter, but you would need to boost
the blue's out put to match the the brighter picture and will shorten the
life of the blue,, and the colors would not be as good as they are now.

Cutting down any reflected light would always help.

the with on the blend was 49" tall and 132" wide, or 4' by 11' each projector was doing 4'x5.5(sorry guys its hard to break old habits. i meant 132"X49" LOL)
the worst problem i encountered with the blend with the nv1100 quadro was with monitor detection. i literaly had to unplug the second projector and plug in a 19" monitor before every re-start. after it was started up and detected two screens i could disconect it and re-conect the projector... if it wasnt for that and the 1-2 seconds per frame i would've loved it. 1400 lumens would've beat a g-90 and would've been brighter/sharper for scope.

yea the briteness would be nice to prevent it from blooming. i run smaller screens and i dont mind a warmer picture. size 10 font is clear and readable on web pages when i run 2048x1536 but any smaller than 10 is hard to read.

my rosters barely have any keystone and ive elevated and tilted the projector on a couple end tables to do so. the tube faces measure 4"x4.5" so i use max with and theres alot of virticle that could be used. if could put up with a 5x4 ratio screen instead of 4'3' i bet there would be an even bigger resolution gain but i would be limited to 1280x1024 and 1800x1440 so that doesnt offer much flexibility but i guess i could put up with it on computer games.

has anybody tried using a mylar mirror or a prizm to make anamorphic mods?

sonynut to get that pic i ran my contrast at 20 and my brite at 40
when watching the hdtv i have my contrast at 40 and my brite at 65 when the lights are on, 50 when lights are off

heres the rest of my pics... most of them are really blurry even when scaled down from the original size. original size of the pics was 2832x2128 so thats probably why some of the earlier pics look so sharp. the second scan lines pic you can see scan lines but only before its scaled down to 25% of its original size.
