View Full Version : projection size
axellagerlf 11-19-07, 02:45 AM On my 100inch screen, the only way to fill it with a HD film is to bump the vertical size up to 80, but then it does exceed the tube face if I display the raster... but does that matter? I mean as long as I bring it down after watching a movie.
Btw you guys Ive been experimenting alot with different image enhancing softwares and the color depth and the shadow detail looks like, or at least is pretty near the 9inchers...:) Ill post some pictures later once my friend remembers to bring the dig camera if he ever does:D
Anyhow is it just the monitor Im using right now or does the shadow detail look way off even on those G90s?
nashou66 11-19-07, 09:17 AM the raster is ok to go over the face as long as the displayed image does NOT!!! otherwise you could blow a tube. You might need the anamorphic sqeez mod done to your vertical deflection board. look it up , a few resistors changed is all it is.

It already has the anamorphic squeeze mod, its just Im using WMP that Ive optimized the projector for and the ffdshow settings just doesnt apply to it..
When I use powerdvd the screen is full but then I loose so much in PQ..
try using wmp yourself and see if it makes a difference:p Im gonna post some pictures once Im done down... err buying Matrix in 1080p..:rolleyes:
nashou66 11-19-07, 01:05 PM I dont use a HTPC at all hate them to much work. I have a lumagen HDQ Video Processor running four resolutions. 1080p48hz blu ray/ HD-DVD 1.78 ratio, 800p48 Blu Ray/HD-DVD 2.35 ratio. and Standard dvd sdi output 960p48hz both ratios. and then 1080i60hz for high deff TV.
Once you save cash and have money to spen look itno a stand alone video processor they are much much better than HTPC's.

ThomasW 11-19-07, 01:49 PM I agree with Anastasios above, have a HDP videprocessor myself and am very pleased with it.
axellagerlf, you probably could reduce the porches in the videosignal, if you use a HTPC it can be done with PowerStrip software. A standalone videoprocessor will do it too, much more reliable...
PeriSoft 11-19-07, 03:50 PM I'd correct Nashou by saying that standalones aren't necessarily better. They're *certainly* not better per price, and I doubt they can match a high end PC running good software. They *are* easier to set up.
If you're willing to do some tweaking (which, presumably, you are, since you have a CRT) HTPC is the way to go. Guys here talk about endless problems with black crush, gamma, having to get extra things to put in the video chain... I've got a 1271 I'm using before I get my HT set up downstairs, and I just turn brightness down until it's jet black and run the gamma slider up. Bang. No crush, inky black, no $1000 for another little box. And if I wanted, I could alter per-channel, change curves, etc, to make the grayscale tracking far better - all with a PC you could get for $300 or so. Absolutely no contest, not in a million years, in exchange for ten or fifteen hours of learning curve.
axellagerlf 11-19-07, 04:36 PM Uhmn no offense you guys, but buying a blu ray player and dvds for that is stupid..
and tons of tweaking such as gamma and brightness can be adjusted as well,
the image I get now is 110% better than when I got it; the color depth is, judging by the screenshots posted here, as good as a sony G90 Im serious there are tons of color tweaks to be done..
NO need for Hd-145 lenses anymore..:d

You have a lot to lear young padawan ;)! yes HTPCs are good but no where good as VP's and there is an ongoing argument here. I had a HTPC and wehn i got the Lumagen the picture just popped off the screen! better control of all video sources. and the Algorythyms written in VP's are far superior to HTPC's which mostly use generic older variations of scaling and processing.
here is a link of that argument.

i guess its what you preffer, and i preffer VP's especially the lumagens great customer service and they LISTEN to what the customer want,s lots of color calibration options if you have the know how and time you can get excelent results and better than HTPc,s.
And regarding the HD144/145. its not only the color corection its the resolution of the lenses. They are Just better than the HD 8's. sharper. HD 8's just cant show off true 1080p like the hd 144's.here is a pic from cuts site on the hd 144's

Give yourself time watching the Marquee and then try find a color filtered Marquee to compare it to. I don't care how many custom color settings you use the tubes are unable to reproduce correct colors without being filtered.
I thought my Marquee had good colors before I added the colored glycol, after the change all I could think about was how long I'd been having to deal with the wrong colors. ;)
You really have no idea how much better it can be before you make the change.

Took me less than an hour to start tweeking using my HDQ not 10 hours.
sure for color correcton a HTPC will be cheaper but you dont get the quality video processing like a VP gives you. i have had a pc and it was great while i had it but all I'm saying is the Lumagen i have now in its place is much better. i run that old PC through the HDQ because of the better processing and because i lie to watch some iTunes stuff on the big screen. thats the only reason. Also Lumagen is constantly listening to what we want. 21 point gamma is next. i used that gamma slide and you cant get the fine control like a VP gives you. once again this argument can go on forever.

I might not be that good at calibrating a crt, but Ive got years and years of growing up with computers enhancing colors and such and I dont want to sound disrespectful but those pictures are not impressing me, well... except for the sharpness..could be better.
But theres tons to do with the colors, if I were to post some pictures from a regular dvd would that be kcomparable color-wise? I mean Im telling you the utilities I have is making the colors go up 48x the normal without experiencing any color leakage...
Ill post some pictures in a separate thread tommorow...
nashou66 11-19-07, 07:48 PM Keep the pics in this thread or post them in the screen shot war thread no need to post a new thread, just too much jumping around with you Axel ! ;) lets keep it simple.

The thing with colors is that they need to stay true to life and not oversaturated which is different than leakage. Many people mistake brighter colors as better when it could be that those colors are completly wrong. if you have a pure whit pice of paper after you mess around with your colors put up pure whit screen from your PC and place the white paper there it should stay white with no change. or if you have clolor software that comes with color chart sample throw up on of those and try to match it that is when you know you have your colors spot on. since you love your pc.s you should invest in an inexpensive colirometer lie the Display One and use the free HFRC softwear and calibrate the colors and grey scale right. go to the callibration forum for more info. you seem like a bright inspiring kid who likes to learn. i'm sure in a few more months of playing around you'l have it set up way better than now. I thought i had a great set up with colors and all and after i had a pro come out to do my grey scale i was amazed at how far of my calibration was and the pic tool on a new clarity and 3 dimensionality i never seen before, and this is on a 8000 with a 12 foot screen!
Remember post the pics here, no need for new thread.

axellagerlf 11-20-07, 06:38 PM Too bad the pics we took today sucked..
Anyhow Im gonna get those pictures in a couple of days and then youll be dying to find out what utilities I use, the colors are Not oversaturated they are more vibrant , 48 times as vibrant to be exact:D
PeriSoft 11-20-07, 07:41 PM sure for color correcton a HTPC will be cheaper but you dont get the quality video processing like a VP gives you.
Not to be prickly, but what, exactly, do you think a Lumagen or other processor is DOING? They're... using algorithms in a central processor to adjust the data. There's no magic here; it's not like there's some kind of special wonderthing that's in a Lumagen but not a PC. Use the right controls, get the right results.
PCs give you more options to screw things up, and more options to get them right. That's all. But there's no inherent difference - a lumagen is just a PC with a more restricted UI. They *might* have proprietary processing, and be able to do nifty stuff with DSPs, but I have my doubts that it can somehow "make a picture pop" in some magic way, any more than putting a new wooden knob on your receiver will make the sound more realistic.
