|
|
I recently got the moome ext fullhd v3 and wanted to setup my BG 1209 at1920x1080p 60 Hz. The problem is that the edges of the picture becomes wrapped. I read somewhere that you can solve this problem by adjusting the SMP, but I didn’t managed to find where the SMP is located on the 1209. Could someone post a picture or describe where I can find it?
Otherwise I was thinking of setting up a lower resolution, for instance 1600 x 900. Or is it much better to go 1920 x 1080?

I am not familiar with what you mean by SMP but my Barco 1209s display 1080p just fine no wrapping of picture but I am using an HTPC/RGB not DVI. Personally I love 1080p on my Barco so I'd aim for that. I may not be fully resolved but it looks very nice.

I guess problem is in your sources timings. Too small horizontal porch settings for analog projector.
What is your source? With scaler and pc you can fix this, but with stand alone player can't.
In some cases adjusting projector hig freq mode to work earlyer could help. As a default it wont be active with 1080p60 in 1209.
Wider raster will only help if you can't get wide enough picture to fill tubes.

HI Murillo, i have a 1208s (same tecnology as a 1209/2) with sony 9"LC tubes and lots of mods on it to improve picture.
One of these mods is a HDMI input based on HDfury2 directly mounted on port3 board. Using hdmi input i suffer, as you do of a kind of fold over at 1080 60Hz.
The wrapping on the left side is changing as you move side blanking.
What i noticed is that at 60hz the visible image is definitely larger than raster, so it's impossible to show it entirely. I'm quite sure there is no cut, you have the entire image, but simply you can't see it entirely with Barco 120x series.
You could move it with phase and get more left side visible, but you will have a lost on the right side. At moment i'm loosing 5%, but with my old BG1200 the situation actualy was worst. It seems newer Horz. cards help to reduce the issue, too.
I was quite sure was due the HDfury2 and a bandwith issue (1080P 48Hz are OK), but if you told me that newer Moome V.3 and his higher 225Mhz pixelclok doesn't solve it, i'm quite worried!
So it seems an issue that involve all kind of external D/A convertor and Barco 120X series that doesn't love the 60Hz signal coming out from them.
Notice that if i connect my HTPC in analog domain to 5 BNC i could easily show 1080P 60Hz or even 72HZ pattern without any issue.
My actual setup.
HTPC hdmi/dvi-d output 1080i or 1080 24p.
NEC Theatersync HQV Realta scaler 1080P 48/60hz Hdmi output
Internal D/A converter (HDFury2) soldered on Barco internal boards......jumping all external motheboard connectors.
I love the image i get with HDMI.... is definitely more dynamic than analog one (also compared with a scaler with RGBHV output).....it has just more punch!! ...i have a real 1080p 1:1 pattern fully resolved... but with a 5% of the image non visible at 60Hz.
I wish this help the discussion.

Thanks for all your answers. I use a PC with ATI HD 5 series card. How do I fix this with the PC? By the way I don`t use powerstrip.
Best regards

If you want to connect analog output of your pc to 5 BNC port of your 1209 you have to use Powerstrip even for setting negative polarity that Barco require on port 5. An alternative without Powerstrip is port 3, but you need a custom cable to use it.

If you use Win7 you can use EDID override method. It also seems that Powerstrip will also work with ATI 5 series these days.

Also check if your projector is in high freq mode with 1080p, that use smaller flyback time and could help to wrapping picture. When high freq mode is active, there is green led on in Horizontal deflection sub board (that small board).
High freq mode switching point can be adjusted between 60-90 kHz by Vertical deflection board P1 potentiometer. Factory default 75 kHz is at potentiometer mid position.

I use it today without powerstrip and it works fine, ecxept for the wrapped edges. I connect my PC to the Moome through a hdmi and from there to my BG with a 5 bnc cable to port 5.

I know.... but the wrapped edges are because the Moome (as my HDfur2)...if you try your PC without Moome you will not have wrapped edges. To do that "in anolog domain" you need to set negative polarity, powerstrip is an option or external converter as Extron or simply using port3 custom cable.
Wrapped edges are due because the interaction between D/A converters and Barco 120x series. Marquee, Sony prj doesn't show this issue.
That's i'm trying to solve.

With D/A converters using High scan mode help a lot reducing the issue, but it's not enough to eliminate.
Anyway.... if you want 1080P 60hz on a Barco 120x you definitely should be better set it in High Scan mode!

If it would solve the problem, I think that the easiest solution would be to buy a custom cable for port 3. Where can i buy such a cable and what´s it called. I have one question about this though, I heard that the image quality of port 3 is not as good as port 5. Is this true?

Depends on models. Usually older models have a better image using port3. Newer models have improved port 5 and port 3 for some reason it's not as good.
1209 is an older model....so enjoy with port3!!
