new projector

[carter]

just picked up my new projecter optoma hd65,i no this is a budget projecter but its really for a bit of fun and im not looking for the purfect image.

ive hooked it up from my bdp 350 via my amp onkyo 705 and it seems to be showing little crackles of white (reminds me a bit of an old style film)any ideas ive tried it with sky hd and sd chanels and still has the same efect also with games on ps3

screen is 80 inch and projecter is about 3meters away

is this going to be the case with all budget projecters because i cant wach it like this any help with settings pls to resolve this

That's not normal. I'd get in touch with your retailer.

But do try another HDMI cable in case it is the fault of the cable - which one are you using, and what length is it to the PJ?

 

[Andrew Everard]

HDMI cable sparklies, maybe?

 

[carter]

projecta ? have i spelt that wrong

 

[carter]

hdmi is 15meters long

 

[Andrew Everard]

Then it could well be sparklies, caused by the cable struggling to pass the signal over that length.

15 metres long ?? was that a typo ?? did you mean 1.5 m ??

 

[carter]

no typo 15meters

nodnarb4444:projecta ? have i spelt that wrongdepends , if your 16 , and from peckham , its sorted .

otherwise its projector

 

[carter]

how do i get rid of sparkles? booster maybe?

could a mains filter help?

nodnarb4444:no typo 15metersah , well the one thing that many hdmi cable tests have found is that when using long cables , over 3 metres , a good quality cable is often better than a cheapie , maybe thats the problem ??

[Andrew Everard]

Well, assuming the cable is certified to carry 1080p over that length, there shouldn't be a problem. A booster may help, but effectiveness is unpredictable. Mains filters won't help with this problem.

Best bet is to try another cable, or test the projector with a shorter length, so at least you can isolate the cable as the cause of the problem.

 

[carter]

£13 to be honist this is a cheap project.will a booster help?

 

[Andrew Everard]

Not if the cable isn't up to delivering signal over that length it won't...

 

[carter]

will give it a go, gonna get the ps3 from upstairs.will have to stand on a chair to test it as i only got 1m cables spare

 

[Andrew Everard]

One of the reasons I always advise testing out any cables/components before making permanent installations...

 

[carter]

yes!after a bit of a circus act in my front room with a ps3 and a meter of component and hdmi.it is the lead at fault and i dont have to return projector.

now i just need to pull out old hdmi order new hdmi ,test it then install it.(in that order)

andrew would it be worth using component for this setup as its only 720p

and can you edit thread tital for me to correct spelling. cheers

 

[Andrew Everard]

Component cables are probably even more prone to interference over long runs. I'd suggest buying a good-quality HDMI cable certified to give 1080p over a 20m run - to be on the safe side - make sure you get a 'money back if not satisfied' guarantee, and test it before installing it.

And yes, will change the thread title, but don't have time to change all the ensuing post titles.

thanx andrew,

i will get a new hdmi,think im gonna stick to qed from now on.and i will get this one from a shop that i can return it to.even if it does mean paying a little more.
