Need help on my SP4805

[tiger74]

I have just gotten myself a 4805 after reading so many good reviews for it.

 

But the image I got was a bit fuzy/noisy.

and on moving scenes, sometimes i can scanning lines on the human face and the edge of the face is not smooth.

this does not happen when the human face is very close up.

 

I am feeding it from a cheapo LG player which could only output 576i or 576p

and I am using component (belden 1694a) cables.

I tried with 576i, less fuzy, but the whole image turns dark, not so sharp.

 

my questions :

1) is there anything I need to set/adjust on the proj?

2) is the problem cos by the mismatch of the 576p vs native 480p of the proj?

3) is it becos I am using a cheapo player? need to upgrade player?

 

 

thanks for reading. pls help.  ???

Since U mentioned that it's less fuzzy when U output interlaced to your projector, my guess is that your player is not doing a good job in the de-interlacing process. Since your projector is new, there may be also a possibility that your projector is faulty on arrival.

 

My advice is try to borrow/use another decent DVD player & do a test to confirm whether it's the player or projector's fault.  :)

The problem is in your player. if the DVDP can only output 576p or 576i, it means that it force-converts all standard 480 lines NTSC DVDs into PAL, which would result in the mentioned-Jaggies.

 

Change to another DVDP that outputs 480i or 480p, and your problem will go away.

hi limestone,

 

but when i read on the specs of tis proj,

it says it is compatible with the following video :

1. Component and RGB HDTV (720p, 1035i, 1080i)

2. Component EDTV (480p, 576p progressive scan)

3. Component, composite and S-video standard TV video (480i, 576i, composite SCART with adapter, ...etc)

 

so what does "compatible" mean?

i am really confused.  ???

appreciate your help here.

 

 

thanks!

[tiger74]

oops, i think i type my reply on the quote.

 

anyway just a point to add,

does compatibility means you can display the image, but no mention abt the quality of the image displayed?

Ya U r right. Compatibility does not = to quality. It simply means it's able to display all the various types of video inputs listed.

hi bro,

 

looks like we on same boat cos i also just bought it 1 and half months ago.

 

regarding the fuzy image:

 

1) The whole image turns dark because that interlace and progressive signal is different, so it will result is different brightness and contrast. to solve this, just simply recalibrate your PJ using THX Optimizer or AVIA to achieve the same image with equal brightness and contrast. Just do a test and u know what i mean.

 

2) Fuzy image also result from player. I am outputting image in 480i, give your eyes a chance, slowly u will see improvement over 480p signal. Its is dependent on how gd your player is outputting the image in 480i. my previous JVC player i output in 480i, but result in alot of fuzy or scan lines on image. i read pretty gd reviews on pioneer dvd player, which are cheap and gd, also support divx and optical output. i got myself a Pioneer DV-380-S and output it in 480i, now no more fuzy or scan lines. anyway i bought the player at $118. cheap sia! hehe just a standby piece for me to endure until HD. ;D

[sas_aaron]

try to get a dvdplayer which output 480 lines. using 576 line player will result in downscaling.

 

I tried with 576i, less fuzy, but the whole image turns dark, not so sharp.

 

also after you calibrate to correct brightness and contrast, dun switch back to progressive output first, try it out for few days.

 

actually outputting 480i signal to 4805 will result in a very small border around the image. but i zoom in the image until the small border gets out of my screen area, so i get a perfect looking image on my 80" screen(note this method will result in some projected area being overlapped outside the screen, but since its black border, u wun notice it, just try and u know what i mean). the 480i through 4805's faroudja deinterlacing chip really looks gd, which can deinterlace more scan lines than in 480p mode. hehe.  ;D

Get a DVDP with HDMI or DVI output. U will not regret it.

I second that.  ;)

[tiger74]

thank you all for your help.

 

I will be bringing down the proj to the shop to test and confirm that it is really dvd player prob,

since it is still within 7 days, if really something wrong with the proj, at least still can change.

just to have a peace of mind  :P

 

Limestone and Phil,

 

so which model of HDMI/DVI player you recommend to use with 4805?

a budget one will do :P and estimated retail price?

 

I need to get a M1DA-->HDMI/DVI cable is it?

is there such a cable in the mkt?

is it better to get player with DVI port or HDMI port?

 

if I am not wrong, HDMI carry audio signal also,

does this means it will output audio to the proj speakers?

so how abt my coxial audio connection to the amp?

Hiya,

 

I  don't use the 4805 but I am a fan, I think you need an adapter on your proj side if you plan to use the HDMI cable as 4805 only accept DVI.

 

On audio you still need to output thru Optical/Coaxial digital thru to your AVR even if you use HDMI.

 

From your laments it kinds of puts me off the 4805 now, maybe I will look at the Panny ae900 now(even thou' it is a little bit more exp.)

Hi,

 

I'm a 4805 user myself, although had some minor problems with it but not as bad as yours & aaron's. There is such a cable M1DA-DVI, bought mine (10m) from Fastlogic.  But u might want to consider buying a HDMI cable and a M1DA-HDMI adapter at the pj end for future use. Denon 1920 dvdp with HDMI (~$470+) is pretty good to start with..  :)

 

Good luck.

 

[tiger74]

last nite then i discovered that the dvd player tat was laying in my other bedroom can output 480i/p

and i hooked it to 4805

and BINGO!

the fuzy images and scan lines are gone!

 

shiok!

 

thanks all for your help and advise. :)

really appreciate!

 

DIRTRUN, don't be put off by my post on 4805, it is indeed a value for money proj  :)

the fault is in my dvd player. >:(

[DIRTRUN]

Hiya,

 

Okay, yours is solved by the change of DVDp, and I am not knocking the 4805 in anyway here but there is another thread here in Xp discussing the 'Buzz' thing at its power supply and also the need for an adaptor for HDMI connections seems a little troublesome(I wonder if it hinders Picture Quality)and since I am still looking, the panny seems a better, more durable and current PJ although it is more expensive.

 

Again just my thoughts only, not meant to offend past, current and future 4805 owners.

Panny AE900? Totally different class of projector bro. Of course much better. :)

Go for the best you can afford as always, else will regret!

Hiya Quest,

 

Really! Well I am a noob where PJ's are concerned.

 

All I know is that the the 4805 is DLP but it is like what 2003 model(or something like that, not good with dates ; failed History, hehehe :D)and the Panny 900 is current(or is it?)ly one of the best budget LCD Pjs in the market.

 

What is diff between the two tech is what I read(unfortunately reading and absorbing is 2 diff things for a newb, hehehe :D). I have seen the 4805 in action for a short while and the picture is nice, I have also seen the Sanyo Z1(yup, real old, rite), I think but that was not so great real blur sort of picts, maybe the room wasn't exactly dark to begin with, I don't know...

 

Care to enlighten me on your expert opinion, bro?Hehehe ;D

 

Cheers.

4805 is a 2004 model.  I bought it just when it was released on 24 mth credit card instalment.  Now still on instalment number 21.

[mcmaranello]

recently hooked up a pioneer 919 using component & tried to play some LD but realised my 4805 somehow was set at 576p and show rubbish on screen.  I've gone thru all the settings and can't seem to change back to 480i to match the LD.  I thot the pj would automatically detect the signal, as in the case when I play dvd with 720p, but not with LD. Anyone knows how? Or is it a problem with the LD player?

[Quest88]

Yup, 4805 is a 2004 model. Came out around March or April from my memory.

 

Care to enlighten me on your expert opinion, bro?Hehehe ;D

 

Ok this is my very brief summary.

LCD offers better color saturation, perceived sharper image, and usually has higher ANSI lumens. But it may be prone to pixellation (screendoor effect), and long term image degradation (i.e. shift in color balance due to age).

DLP offers better contrast and black levels, but may have rainbow effect.

 

With technology advances lately, the line between benefits/problems of LCD vs DLP is narrowing in all areas.

I am still a DLP fan, but really, you should just go for what you perceive to be better.

 

The price difference between the 4805 and AE900 should be quite great. Should be comparing something nearer bro. :)

[limestone]

 

I'm a DLP fan as well... cos rainbow effects don't irritate me as much as screendoor effect and LCD-hue shifts do...
