Plasma Panasonic 50PHD8, analogue in with VisionPro HDP. Native Resolution?

[gorman]

It's been months and I'm still not sure of having the right timings for native resolution. I'm going in through RGBHV--->VGA.

If somebody has the same configuration, could he please list his timings settings for 50 Hz or 75Hz, 59.94Hz and 71.92Hz or 47.95Hz?

I tried and tried, I searched and searched, but I'm still missing one pixel here or one pixel there... Please, please... if you have my same equipment, help me out.

All you do is put the '1 line on/1 line off' line pattern on, standard timings.

With the vertical line pattern adjust the horizontal size on the plasma until it snaps in. And with the horizontal line pattern adjust the vertical size on the plasma until it snaps in.

It really is as simple as that.

[gizlaroc]

Oh, you may want to try 1368x768 for 50.00hz.

[gorman]

See... everybody speaks about standard timings and adjusting... but... from my past experience, it's not so easy. If I go with standard timings for 768P I get a picture completely moved off the centre at 50Hz...

I would really like for somebody with my same equipment and connection to provide me with their numbers. I'm feeling so stupid after so many months of trials and (too many) errors...

[gizlaroc]

Yeah of course you do, the screen needs positioning once it is pixel mapped.

Do as I said before, then put an overscan pattern up and adjust the H and V position so everything is central. You need to do this for each resolution you input.

That really is all there is to it.

Panny plasmas don't do 75Hz or 72Hz (71.92Hz) without internal frame rate conversion, they do however do 48Hz (47.95Hz), 50Hz, 60Hz (59.94Hz) at native resolution with no frame rate conversion; and also accept 1080/24p and 1080/24sF at 1920x1080 (as well as 50Hz and 60Hz).

I have to say that I have some problems with Lumagen and Panny 50-inch at 50Hz with default timings ... the picture is way off centre and needs both service menu horitzontal-size set to maximum and user-settings horizontal-size set to near maximum too. This is not the case for 60Hz, or using other scalers/HTPC at 50Hz.

Take a look at the basic set-up guide on the Lumagen forum site.

The fact that you mention this highlights the reason for wanting to find out the specific timing data that the panny is expecting to receive...this timing data also differs for different refresh rates. The Lumagen must have different default timings than your iScan.

When I had my Pioneer MXE1 plasma I was able to obtain the specific timing data direct from Pioneer...perhaps we need to try and do the same with Panasonic...or perhaps someone like Joe @ TMF could on our behalf.

Has anyone tried running the MONINFO application to see if it returns the necessary timings ? it did for my PJ...must try that.

If the image is severaly shifted then you want to be adjusting the Horizontal FP and Horizontal BP settings...by adding 1 to FP and removing 1 from BP will shift the image 1 pixel to the right etc...well thats my understanding anyway...I think this is what the H & V Shift controls onthe iScan do.

iScans (all the different models) or CenterStage or HTPCs. The 50Hz timing of 1366x768 on Lumagen is different to everything else, which are all pretty much identical.

Thanks for the tips, I already solved my problems ... I was simply pointing out (esp to gorman) that I had issues configuring 1366x768@50Hz output with Lumagen on Panny plasma whereas everything else I've plugged in has no issues at all with this resolution & refresh rate.

Did you not try the iScan timings on the Lumagen ?

When I say standard timings I just mean Vesa timings.

50 and 60hz is just dead easy, 30 second job.

On the CII I use 1366x768@59.94 for 60hz stuff and 1368x768@50.00 for 50hz stuf.
Then adjust the panels size till it all snaps in, at this point you need to adjust the position as it is off screen.

Gorman,
I see that you have posted on the Lumagen forum in the past in the timings section.
I had similar issues as yourselve re sizing the a PAL image using the regular size adjustments of the panel (mine is a 42" panel). To resolve this I had to resort to using the size adjustments in the service menu of the panel. I'm not sure how to access this on the PHD8. I think this is what you need to do - maybe someone else can help.

[gizlaroc]

Hold down the VOL- button on the screen and then press the i+ button 3x on the remote.

Well, just spent a few minutes playing around with Lumagen and iScan and Panny 50-inch.

Here's the original settings:

LumagenPro HDP

VTOT: 800
VACT: 768
VSYN: 5
VFRN: 5
HTOT: 2088
HACT: 1366
HSYN: 84
HFRN: 342
VRATE: 50.00
SIZE: 150,84
POSITION: 0,0

VTOT: 800
VACT: 768
VSYN: 5
VFRN: 5
HTOT: 1960
HACT: 1366
HSYN: 84
HFRN: 342
VRATE: 47.95
SIZE: 150,84
POSITION: 0,0

No wonder the 50Hz picture was hard for screen to handle, 2088 wide?

DVDO iScan VP30

H-SHIFT: 256
H-SIZE: 1366
H-FRONT: 64
H-SYNC: 112
H-BACK: 256
V-SHIFT: 18
V-SIZE: 768
V-FRONT: 3
V-SYNC: 6
V-BACK: 18

LumagenPro HDP - new timing

VTOT: 800
VACT: 768
VSYN: 6
VFRN: 3
HTOT: 1920
HACT: 1366
HSYN: 112
HFRN: 64
VRATE: 50.00/47.95
SIZE: 150,84
POSITION: 0,0

Dead easy to centre on plasma with Engineering/Service menu -- remembering to NORMALIZE the consumer SIZE/POS menu first.

Also, with new setting there is no distortion on interference on the 'Alternate Vertical Columns' test pattern on Lumagen, where there was before; never has been on iScans or other scalers though (screen must prefer the nearer VESA settings). Also changing the vertical times on Lumagen made the picture stable, as it became unstable (odd flicker every ten seconds) when I changed horizontal timings.

Good work Stoo: I usually just knocked the HTOT down to 1860ish then reduced Hsync and that got it miles closer then worked from there. I never found it an issue. I've asked Lumagen to look at changing the default 1366x768@50 timings
