Samsung BD5100 1080 50Hz - 60Hz resolution
« on: December 05, 2011, 12:56:40 pm »
I bought a BD5100 over the weekend to use in the interim before I buy a OPPO player later.

I have it playing through a HDFury 2 to a CRT Projector.
The Projector Can sync to 1080i @60 Hz
When I watch a Blu Ray movie the Player puts out 1080i @ 60 Hz  (so all is well).
When I watch a DVD movie The Player puts out 1080i @ 50 HZ (The projector is set for 60 Hz so the image is either scrambled or resolved to the left 3/4 of the screen).

Has any one found a way to force the player to always put out 60Hz?

Most DVD players can only play back PAL DVDs at 50Hz. Only players I know of that can convert 50Hz discs to 60Hz are the Oppos.

Is you projector imported from the States or something? It's quite strange that it can't display a 50Hz signal properly. Given the choice between 50Hz and 60Hz, I'd pick 50Hz every time, 60Hz playback judders.

Yes: The projector is a RCF CRT Projector I bought about 3 years ago from Curt palme.
It only has a RGBHV  video connection PC type.
THE PHILIPS DOES CONVERT 50Hz to 60Hz I test it on my Acer LCD monitor in the menu under info it states the signal as 1080i 60Hz.
It accepts the 50Hz  from The Phillips DVD player but the image is squashed to the left . I can fix it by adjusting the white image size, but that means redoing the red green and blue image convergence every time I change between DVD and Blu ray.
If I set it up for 50 Hz and play Blu ray movies the image goes of raster to the right (NOT GOOD)
What seems t be my last resort is to use a auto HDMI 3way switch and use the BD5100 purely for Blu ray and digital media through its HDD feature etc. and the DVD for DVD's.

Ok first things first. You need to go and do a little homework here. Go and read the manual of your HDFury.
The problem you are experiencing is due to the fixed rate output of the HDFury. Im not sure if it has the ability to do Vshift with regard to your pixel clock, check to see if it has this adjustment.

What this amounts to is, 50 and 60Hz require 2 different bandwidths. THe HDFury does not auto synch to the new frequency and so ends up garbling the signal if it its output is not set to match the input in terms of the pixel clock. It should have an adjustment, however as far as i recall its a manual adjustment, meaning everytime your change from a 50 to a 60Hz source you will have go to the HDfury and change the setting. The newer HDfury3 allows you to digitally store in memory an auto synch for the pixel clock depending on the incommin source frequency.

I had a similar problem with a competing product and did the following. It had a potentiometer to adjust the clock and i used a mid bandwidth setting so i could cover 50 and 60 Hz . The problem with this is will allow a picture for both sources , but as you have already seen, you have a offset picture. You will have to save both the 50 and 60 HZ options into your projectors memory after adjusting your projectors image position for both sources individually.

The bottom line is your problem is actually the limitation in the HDFury.

I just had a look at the HDFury2 manual. I see it cannot change the pixel clock for an RGB output. Now i see why you need a Bluray player that will force output to a specific output frequency. That will introduce many image issues in itself.

Thanks for all the info.

What you say makes absolute sense.
Here's what i Have
1. RCF CRT projector only has RGBHV input , S-video and composite Video inputs (one of each)
2. When I select the S-Video or Composite video input on the remote it allows me to select 5 colour system options:

A.  PAL BGHI / NTSC  -M
B. PAL 60Hz  / NTSC 50Hz
C. PAL - N  /  NTSC 4'43
D. PAL - N / NYSC - N
E. SECAM

3. When I select the RGBHV Input there is no option to change any Colour System As its suppose to get it from the source (PC) According to the Projectors manual. HENCE the reason why I always had it running at 60Hz with the Philips DVD Player.

What's strange to me is that when I play a blu ray through the HD FURY 2 it clocks at 60Hz.

I have another projector that i'm going to set up soon (BARCO 701s HQ) thats got a little bit more option on the input side maybe I'll be able to run it better through that.

Cheers.

Maybe I'm misunderstanding you here, but BDs generally play back at 60Hz if you aren't able to view them at 24Hz.

OK so then using two different players for DVD/BluRay looks to be only option apart from spendong $250 + on a video processor that has a HDMI Switch.

Going to 2 different players will not solve the problem. Lets just simplify things. Firstly your blurays will play at 60Hz since you can forget about trying 24Hz on your projector as thats outside of your specs. Secondly  your DVD's if they are Pal will play at 50Hz, however since we are Region 2 , that encompasses Japan which is NTSC which is 60 Hz. Your player will be able to play both. Now to put a spanner in the works, if you dont have a region free player you will not be able to play any discs from the good old USA due to it being Region 1.  However most bluray players are region free for dvd's but not bluray's.

To solve your problem, you need a player that can output a fixed refresh rate, either forcing the player to 50 or 60 Hz. That will create massive judder issues as there is no way to do a smooth conversion, most noticable on motion and panning.

Alternatively get a newer version of the HDFury and use its adjustable setting in terms of image shift on an RGB signal. This is more expensive and complicated as im not sure how many memory settings you have on your projector on a by input basis. You would then have to save the 50Hz signal into one memory bank and the 60 Hz one into another, so that the correct convergence , image size and position is retrived , depending on your imput signal.

Do a firmware update, could fix a variety of your issues...
LF: Cheap but decent interconnects so I can try to hear the difference, or not.

If you mean on the blu ray: its alreadry up to date.
If you mean HD FURY2: Haven't checked and doubt that it wil fix any thing.

What you playing at might work:
The Philips DVD Player can force out put to 50Hz or 60Hz and is region free but the Blu ray player can not force 50Hz or 60 HZ.
The Projector has 4 different aspect ratio that it can store.

Possible solution:
For DVDs on the Philips DVD player.
Save one for  50Hz as most of my DVD are 50Hz

The samsung Blu ray players 50hz output doesn't run stabel with the HD Fury2 foe sone reason.
It starts out good and then ripples out of sync without warning.

So For Blu rays on the Samsung.
Save one for 60Hz

This way I should be able to run ALL of my DVD's with out judder as I can Select the correct refresh rate on the player and correct aspect ratio on the projector.

Thanks
For all the input I'll give it a try tonight and see if the aspect ratio thing works.

Running film at 60Hz is what causes judder, 50Hz and 24Hz are judder free (movies at 50Hz are slightly sped up though). It's due to how a film's 24fps are spread across the various frame rates.
