Need HD Powerstrip settings for Sony 12XX

Mike, I have an ATI HD 3650 by Visiontek 1gig.

Powerstrip obviously not a problem for ATI. Its just that I don't know how to adjust the settings. I spent another three hours last night experimenting with presets I thought might work. But most stretch the picture or distort it or look wrong for some other reason. (This is three hours of probably twenty five spent over the couple years trying to find another good resolution for this projector that would work with HD. I am really giving it the old college try.) 800x600 has been an awesome resolution for this projector for DVD. But while Blu Ray looks slightly better I am pretty sure I am not giving it the room it needs to show the extra detail.


I am really hoping to find someone(s) who has settings in place I can just copy.

I guess my projector is out of favor. I am looking at an above post for the G70 and people are posting favorite HD settings right and left for it.


Is it likely any of the settings for the G70 would also work for a VPH1271(2)?

hmmmm....three years! Wow.....is it a very old PC?


you may be able to try 720p. If I recall my 1271.....I think it used to sync to 1080i too. It may sync to these resolutions but whether it will resolve them or not ......well you will have to see it for yourself.


If you have a current generation video card.....powerstrip is useless. It does not work with the latest cards......and in fact it is not even required. The drivers have that capability now.


for example my nVidia drivers have many of the settings which powerstrip exposed.

I like to Frankenstein my computer. The one in the theater has the case I bought back in 2000. Its been pretty well gutted and replaced with all new stuff. Dual core processor, HD3650 card last week and the Blu Ray player.


People often say to me synch it to 720p or 1080i. But while I have tried I have no idea how to do this properly. I am not even sure what 720p means any more. It seems like there are all sorts of ways to get to it. I have tried all sorts of what are supposed to be 720p settings but they don't seem to work. I am told this projector can not resolve more than 600 lines. What I am used to is two numbers, like 800x600 or 1370x768. I don't know if any of those correspond to a certain "P" or "i" all by themselves. (I know p is progressive and i is interlaced). Everything I try seems to make a mess. The best I can find are tolerable settings. But nothing I can live with or enjoy.


I am not totally stupid. I retubed my own projector...(rather nicely I think thanks to all the info on this forum.) But I am stumped when it comes to understanding how to fine tune Powerstrip. Powerstrip humbles me.

I am not locked into using Powerstrip. If I can get where I need to be with Catalyst Control Center I'd be even happier.

But I am at the point where I need hand holding. If possible I just want to type in the numbers and push buttons from an all ready recipe.

If I have to experiment and tweak I can't do it the manly way where you just keep trying stuff that makes sense until you find the right combo.

I have had my fill of that. I am no closer today to understanding the adjustments than I was two years ago.

Okay. My goal here is to come up with a solution not just for me but for people who might have the same problem down the road.


I found a temporary solution to my problem of getting power strip settings for my 1271. I tried some in the crt thread about 1080i or maybe its 1080p for G70.

Someone was using similar settings for this in his G70 and also his G90 so I thought maybe they would work in a 127x.


The do sort of in the sense that I don't mind watching movies this way, but I wouldn't invite someone over to show off my system with it looking like this.

Here are the settings I am trying.


PowerStrip timing parameters:

1920x1080=1920,88,44,148,1080,4,5,36,118800,9


Generic timing details for 1920x1080:

HFP=88 HSW=44 HBP=148 kHz=54 VFP=4 VSW=5 VBP=36 Hz=48


VESA detailed timing:

PClk=118800.00 H.Active=1920 H.Blank=280 H.Offset=72 HSW=44 V.Active=1080 V.Blank=45 V.Offset=4 VSW=5



You can cut and paste these into Powerstrip.

It provides reasonably clear resolution. Text is a little soft, but somewhat readable and essentially

its a decent looking image. But it demonstrates a lot of the problems I run into when trying to do hi def settings in Powerstrip with this projector.

One is the slightly soft image. Second is some pretty severe distortion that isn't really correctable. It looks horrible on the windows desktop but not so noticeable when playing a movie. I am providing a picture to give you a sense of what I am dealing with.




This is a rough and not exact representation of my screening room. Imagine I am projecting a gray background with a red rectangle. After forcing the image to center with "shift" and sizing controls and physically turning the entire projector to sort of get the image centered I end up with something like you see here. There are distortions which are not symmetrical so I can't adjust them out with "pin" or "keystone" or other settings which work the top and bottom at the same time.

The bottom line of the image is wedged on that side. There is some mild bowing along the top. Making the screen fit exposes a little bit of raster that isn't usually used thus the lighter and bluer left edge.

I really have to mess around with sizing and shift and blkg to make the image fit the width of the screen in a way that it isn't affected by strange artifacts and distortions. I can use my masking and "size" out some of the problems so they aren't seen so much. But these are obviously not natural or ideal settings for this projector. I am forcing it into submission.


When I run it at 800 x 600 It snaps into place and I can drop a plumb bob down the verticals and a straight edge along the horizontals and they are all true. I suppose I could do more with zone but I am sure I would hit limits if I tried.


Even if I can't find something perfect, I'd like to find something better. A year ago when there were more people running 1270 series projectors it seemed there were quite a few people happy with their high definition settings. I am hoping for the sake of myself and others running this projector that there are a few happy campers out there willing to post their settings in detail .

I have a 1252 that I use to run ( recently started to die, not bad for an ex Bar projector that was covered in nicotene when I got it with hours in the stratosphere )


I tried 800x600 4:3, 1024x768 4:3 they looked ok, 768 was a little soft.


then I tried 16:9.


I tried 1066x600, I tried 1184x666, that in a 16:9 ratio with the DVD software set to stretch the picture vertically and then use the projectors RGB controls to vertically squash it back to 16:9, it looked great the softness of the old tubes made for a more film like appearance.


On my machine ( which has 14 000, 24 000, 34 000 hours can't tell because of the 4 didget counter ) the 1066x600 looked great at 16:9.


Then I tried 1080i. That synced and locked and was the easiest to set up ( again at 16:9 ) Upscalled DVD from my RealMagic card looked great.


So try 1066x600, 1184x666 and 1080i ( 1920x1080 click the interlaced check mark in powerstrip ) Set your DVD siftware to anamorphic stretch and recompress at the projector.

and 800x600 looked the BEST to me.. (using HTPC).. all others go 'soft' or some other issue.. Need high res.. well get bigger tubes

Thank you so much for this.

Took me a while to really put this into play Analog Rocks but this advice finally got me where I was going. When I tried 1184x666 it did something funky to the tex so it was unusable But the other two settings were respectively great to fantastic.


First I did 1066 by 600 and it was solid and once registered it even looked slightly clearer on the desktop than my never beaten favorite 800x600. And looked more refined than the best high definition setting I had before. All I did in this case was using Powerstrip typed those two numbers into the fields and while it seemed to switch and fight me a couple times, eventually the numbers stayed in place. And it looked teriffic.


I think just doing this alone helped give me the confidence to fight for 1080i one more time. I have tried it before but the distortions of the raster were always too obnoxious to live with. This time I tried a couple new base settings

from the Powerstrip presets and came upon one that looked worth trying to dial in. And man was it worth it. Finally I saw what I would consider Blu Ray clarity where I was looking deeper into the picture and getting more of an emotional connection to the image. What I have going now is so far beyond what I was able to get from DVDs I am now a little spoiled, which is exactly what I was hoping for. Until last night I had been settling for the additional density and saturation of colors, but not really getting much more in the way of clarity. Two days ago Fifth Element looked only about as good as the Superbit DVD. I thought maybe they sent me the pre remastered version. Now its very much clearer. People look solid and deep. So this is really wonderful.


My tubes are less than 3000 hours so I only have some mild yellowing and slight lack of focus. Its encouraging to hear you ran so long with yours.

I'll eventually upgrade to a G79, but I can be very happy with this for quite some time.
