|

Hi
I have a Hd DVD and a Blu Ray Player running on a Sony G70m CRT Projector.
They are both set to 1080P running through the same HDMI cable into the Fury.
While doing a compare between the 2 formats and i noticed that the BD pic is not as good as the HD so I went looking for a setting on my CRT that might be the cause.
What I found in the menu was this
Hf & Vf of the HD DVD is 67.5Khz & 60.0Hz and the Blu Ray is 33.7 Khz & 60.0Hz is this right? should'nt they be the same?
Please explain.
Thanks

The HD looks correct but the BD looks like its set for 1080i.

Yes, the BD player is 1080i. Some players are only capable of 1080p/24 (which your CRT cannot take), not 1080p/60. Yours may be one such player. If so, you'll need a processor to get 1080p/60 pr 1080p/24. What BD player do you have?

Really? I'd be really surprised that any BD player would only allow 1080p at 24hz and not 60hz. 99% of HDTVs out there cannot handle 24fps. Why would someone build a BD player that only puts out 1080p at 24 fps?

The vast majority of Displays in use will not take 1080p/60, so what is the point of it? 1080p/24 is what you actually want and that support has been added to displays.
As an FYI, my player outputs via HDMI: 480i, 480p, 720p, 1080i, 1080p/24. No 1080p/60

Dave, what are you talking about?!!?! It's only been in the last year or so that ANY displays would accept a 1080p/24 input, and then only on the higher-end displays. There are hundreds and hundreds of models of displays out there that will NOT accept 1080p/24, but will accept 1080p/60. Hell, the first HD DVD and BD players didn't even HAVE 1080p/24 output on them - they were all 1080p/60. Guys were using them at 1080i with processors so they could do ITC on it and GET the 24 progressive frames without judder.

If that's true, then there are whole bunch of displays your BD player wouldn't work with - at 1080p at least.
What display won't accept a 1080p/60 input?

You are kidding right? Almost all the HD displays made before the last couple years would not accept 1080p. They typically accepted 1080i, 720p (or maybe just one of those), and 480i/p. When HD DVD players and BD players started coming out with 1080p there were a slew of articles on the web trying to tell those HDTV owners that it was OK that there HDTV would not accept 1080p/60, they just needed to feed it 1080i and it would de-interlace and all would be fine.
1080p consumer displays have only been available for a couple of years. The first couple generations did not accept 1080p input (go do the research). Then 1080p/60 started to be added to those. It quickly became obvious than 1080p/24 was desirable also and it started to be added. If you have a consumer display that accepts 1080p/60 but not 1080p/24 you either have a:
1) Very recent low end model, or
2) A display made in a narrow 2 model year time frame.

Or an analog display that's really old (CRT projector, monitor, etc). 
I see your point Dave. I do agree that until recently most displays did not accept 1080p at all, even the digital ones. Now that they can do 1080p, they're going to want to do 1080p to watch movies or videos (24/30) mostly.
I suppose it makes sense.

Hi
My Blu Ray player is the Sharp BDHP20X.
I have gone through all the settings many times and selected 1080P and the player confirms this although the Picture and the Crt dont.
Things that I have tried are changing the resolution down then back up to 1080p, powered the plaYer off and on and have also turned the CRT on before the Blu and visa versa just to see if there is any differance.
If this is a problem with the player not wanting to go into 1080p what player will do it?
I do not have a problem with 1080P on my HD DVD player, it does it brilliantly.
Cheers

OK, I'd never heard of that model so I just googled it. It seems it is an Australian model.
The player does output 1080p/24. This is going to be the preferred resolution for any blu ray disc. So, what is happening is that when you put the player in "1080p" mode, it is going to 1080p/24. Since your projector cannot handle a 24 Hz refresh the HDFury (via EDID) is telling the Sharp that it cannot do 1080p/24, so the sharp is falling back to a resolution that it is being told the HDFury can do: 1080i.
So, this is what you need to do (and others with more Fury knowledge or Sharp knowledge need to jump in):
Read the Sharp manual and see if the player can output 1080p/60 or, if like my LG, it does 1080p/24 but not 1080p/60 (this would not surprise me as it came out the same time the Aquos line of displays started supporting 1080p/24 input). If it can, there will be a way to set it to two 1080p resolutions: 1080p/24 and 1080p/60. You need to set it to 1080p/60.
If you can actually force it to 1080p/60, then see if it sticks. I believe the EDID in the Fury tells the player that resolution is OK, but someone over in the Fury forum to confirm.
Lastly, if your player does not support 1080p/60, you can either:
1) Live with 1080i or 720p
2) Get a video processor like a used Lumagen HDP to turn the 1080p/24 input into 1080p/48 or 1080p/60.
3) Get a player that outputs 1080p/60
Good luck.

Dave is right he has an LGBH100 like I do and I cannot get it to sync to my moome card with out a VP in the chain for 1080p. I have not tried to set the LG to 720p first and then try it with the moome, some players will not output 1080p@60, it looks for the displays EDID and most will default to 1080i@60 id it cannot connect at 1080p24. At leastt he LG from my experience is like this.
