Hmm, So that explains why my 9PG Plain always buzzed with the keystone setting being adjusted when I used the 9PG with the lenses at a 12 degree angle to the screen.

I'll have to check that in both my 9PG and my 9PG Xtra!!

Also, as for the XG, the Quote from Mark AW is pretty accurate. I do note streaking visibility on my XG every now and then, when I do notice it, it is very very minimal, and probably related to timings.

On my NEC XG when I'm watching a movie or I hit a really bright scene like a 100IRE white scene, there is an extremely noticable buzzing in the power supply. It quiets down when brightness of the scene goes down, and goes up when brightness goes up in a scene etc... What would be causing this? Because that would make my XG a LOT more quiet half the time.

I remember someone here asking for XG Mods, and I commented that it wouldnt need any. However, if someone spent the time, the few things that should be modded on it are:

1: Fix the buzzing in PSU that occurs during high brightness scenes
2: An anti-banding mod for higher resolutions would be awesome
3: This may be out there, but Fan mods would certainly be nice to have as well. The main fan on the deflection board is ANNOYING AS HELL, and honestly even at cinema audio levels I can still hear the damn thing.
4: I dont know if I am the only one or not who has this issue, but I can visibly see the raster being projected from the blue tube on my XG onto the screen. A better way to put it is, if I mess with the blanking there appears to be what I would think is the raster wrapping behind itself, and when adjusting the blanking changes how this appears, but does not eliminate it. If there is a way to eliminate this issue I would PAY to have it done because it is the main quam I have with this machine.

Draganm, your 9PG Screenshot looks much better IMO than your Marquee shot, save for the sharpness at the edges and corners (but that is a PITA to work with on any NEC, more so if your still new to the set). I dont know if its the brightness or the colors, but something in the screenshot looks better than the marquee.

as for 720p vs 1080i... 1080i is fine and all, if scan lines dont bother you. I would guess this would be more visible on a larger screen, but even on my measly 82" screen I can see them on my XG at 1080i.

Dragan, if you are using a video processor or HTPC, the 9PG Plain (so the PG+ and the PGX as well) are capable of 1680x1050. No banding at this resolution on a 9PG, nor my XG. If its a 6PG/+/x I am not sure, I dont know what the difference is. if 1050p is too much for the set, there is always 1440x900.

Gotta love oddball resolutions!

Other than that, I would say the XG is a top notch machine

Well my PG Plain doesnt buzz, and its still got the 10uF in there. I know AussieAl's 9PG Plain doesnt buzz either. Mine is pretty much level upside down near the ceiling, his is up the right way, apparently youll only have the keystone buzz when they are ceiling mounted, and im under the impression it is only the PLUS and XTRA that have the issue, not the 9 or 10 Plain. The Plains have the 10uF cap there, and the PLUS and XTRA have a 47uF, which is meant to be ( or certainly suits better with ) a 470uF.

It isnt something you can see on screen, it is merely a buzzing noise.

The projector in question here is not a Plain, its an XTRA, so the astig should be easy enough to get pretty good all over, once the magnetics are set right, the rest should be doable from the remote and it should be pretty damn sharp. Add that to the fact this thing has coarse and fine point convergence, there should be no reason it wont blow an 8 inch Marquee away when the setup is done good. In theory, if you wanted to have 100% perfect geometry, the point on green will easily allow you to achieve that, so you can have every single box on the whole screen exactly perfect if you want to take that much time.

If there was visual noise on my CRT, I would not tolerate it I would have to fix that. Luckily the audible noises from the XG can be silenced if I choose to build a hushbox. Im trying to decide when I have my XG if I want it to go behind the HT wall or in the HT. If I put it behind the wall I wont hear it at all, if I put it in the HT area Ill have this huge thing sitting on my ceiling

Will probably put it behind the wall and cut a nicely shaped hole out for the lenses

On the contrary, you can put a CRT anywhere in most cases and correct it electronically if the set allows it, vast majority of digitals you need to line the center of the lens with the screen. Obviously youll wear the tubes unevenly, but you can do it

[gjaky]

Actually you CAN do it, but on what price?

That remind's me of the guy that tried putting his Ampro in the corner of the room and tried to project it onto the screen. Didn't work so well.

While you CAN off set a projector I find it's easier not to. Any time you max a setting to correct for the offset you are putting more stress on the electronics.

That isnt from offset so much as it is from plain bad raster setup or bright part of the image way under size.

Also I would like to mention that I have almost all of the settings on the XG to a near default state, I have spent many many many many hours on the mechanical adjustments of the projector, because I know how much easier the electronics will have it in the end.

I DO read what other people say on this forum, even if I dont reply to all of them
