Hi,

i got this configuration:


Toshiba HD-EX 1 - HMDI to DVI cable - Input 1 of the Lumagen Vision DVI -
Output of the Lumagen - DVI to DVI Cable - HD Fury - RTC2200

This works well at 720p output from the HD-EX1.

But when i try to switch to 1080p (or 1080p/24) the HD player will only output 1080i.

What i want to do:
play HD DVD(or later BluRay) with 1080p/24 and convert it with my scaler to 720p/72Hz for elemination the stutter in the picture.


Q1: is there anything i do wrong(wrong settings in the scaler maybe), or is it impossible to do this with my configuration?

Q2: do i need any device to make it run with the Lumagen Vision DVI?

Q3: if the Lumagen Vision DVI cant handle what i want to do, which scaler do i have to buy to get What i want??


Thank you all for your help


regards
Chris

The Lumagen DVI does not accept 1080p/24. You will need to input 1080i/60 into and have it scale to 720p/60. alternatively, you could have the source scale to 720p/60, then have the Lumagen frame rate convert to 720p/72. See which is better.

If you have recent firmware--the Lumagen DVI has per pixel motion adaptive 1080i deinterlacing. Most of the time, this produces results as good as film mode, but it does not have a true 1080i film mode.

The Lumagen HDP would get you:
- 1080p/24 input
- True film mode deinterlacing (for sources that can't do 1080p/24 such as your sat or cable)
- 10 bit scaling (as opposed to the DVI 8 bit).

Downscaling is easier than upscaling, so the 8 bit is not too bad if you are outputting 720. But, there are rare times when you would notice that the HDP scales better.

Sorry for my late replay, was busy the last weeks. And many thanks for your answer

Oh, bad news for me

I tried a few settings now with the Lumagen:

720p75
720p72 (71.93?? cant remember exactly)
720p60

I saved them to different memorys to switch them fast. But i cant see in one of them that the stutter is completly away

Another problem is that when i switch to digital output, i will not get any picture on the crt. But i cant understand this, because on the output is the HDfury wihcih should accept my digital signal and convert it to analog. Or am i wrong with this?


So the lumagen HDP is the first model who can handel 1080p24 and convert it to 720p72? So i have to get some for testing, would be nice if this realy works good, because the differnce of dvd scaled up to 720p and hd scaled down to 720p is amazing What a sharp picture

Something strange happend yesterday:

I played with some settings, i searched the menu for the "pass" option. And while i played with the lumagen scaler i also changed tha resolution of the HDDvD player to 1080p/24. And i cant believe it, it did work. I was able to look 2 movies with 1080p/24 input scaled to 720p/71.93 When i hit the "OK" button, it shows me 1080p 24 input. The picture was completly stutter free, perfekt and smooth

But now i tried it again, but it wont work anymore. Damn, i dont know whats wrong.

So it seems that also the Lumagen DVI is able to handle that resolution, but lumangen disable it. Seems they want to sell the high price scalers first.

Is it possible to pay an update price to lumagen and i can get an vision vdp??

Lol, seems that i found out how to force the Vision DVI to accept 1080p/24

Can i post it here? Or can the forum get problems? Its legal, no modification in firmware or hardware, only in the settings.

I also did a complete restart of all components(i removed it from mains) and it still works.

The lumagen DVI outputs perfect, stutterfree picture

Ok, this is the key for looking 1080p/24 and scale it down to 720p/71.93 with the cheap Vision DVI:

Menu
- IN
- Config
-DVI
-EDID
-USER

And in this USER settings, i changed all resolutions to "NO", except the 1080p/24and 1080p/25.

I did a restart of all components and after this, the scaler accept 1080p/24 input signal

Only problem with this: if i insert a normal DVD, the Toshiba HD player outputs 1080p/50, which is too much for the lumagen. So i used the YUV output and switch to YUV if i look dvd, and back to DVI if i want to look HD material.

I dont know if it works with all firmware version, i use the latest one from the website. So hurry and download it before lumagen disable this option

Hehe, no problem, i like to help ppl if i can

Did it work for you wiht your BluRay player? I am planning to get a PS3 for playing and film. But i think this should not be a problem

Anyone here tryed to upload the HDP firmware on the DVI?
I am wondering if this would work or my DVI is dead after this. The option is selectable in the firmware update toll, but i was to scared and did select DVI Firmware

Oh, and what bandwidth do you need for 1080i/72?? Maybe i also try this But my crt only can handle 84KHz

It works best for me this way:

HD -> before starting HD film, i take a look if i setting is 1080p/24.

Insert HD
Film looks great

SD -> befors starting SD DVD film, i take a look if setting is at 1080i


the 1080p/24 is converted to 1080i/48 with the lumagen -> looks very good

the 1080i is pass through in the lumagen, so no additional circuits in this line -> 1080i/50 -> perfekt picture

I did not use Mem, i use output depends on input resolution, Works good for me

Have stutter free fun with your HD movies

I use the Toshiba HD XE1 (HD-XA2 in USA). There is a Reon-VX scaling chip in the player who did a good picture(with edge enhancement which pushes the dvd to another lvl)

This is the reason why i use the internal. But i will test if 480p looks better. When i had the time, the sun is so great atm, so i will not be often in my homecinema
