Composite issues re G70

I have recently changed over from a D-VHS recorder (which was connectesd to INout B on the G70) to a satellite box. My G70 is controlled by composite inputs (anyway the ones with 5 cables, including Red, Blue and Green). I realised that the satellite box had a scart output, so I purchased a Scart to Red Blue Cable convertor. I do get a picture but it is not very sharp. I have set the G70 to Input RGB and output High Def (not the rgb variant). Could anyone please assist me in getting the picture better. I am very nervous to play around with my existing settings (I drive my HTPC) through Input A on the G70 and that is excellent. Presumably lots of people have driven sat boxes through their projectors? Tks in advance
 
Hi could you look back over your post, could you just check all you wrote and maybe claify some point in there - maybe even break it up into sections - I dont have much time now but will look back later, I dont know about sony's but there are some things above which dont read right to me....

the "controlled by composite....."

"5 cables are R G B H & V" - thats not a compostite input.

I totally dont understand this bit
"I have set the G70 to Input RGB and output High Def (not the rgb variant)"

Am I being blonde today ???

A picture of your input card(s) would also be of help as I have never seen a G70.
 
Hi. Thanks for the offer to assist. I am sure that the G70 receives it input via component cable. I have purchased a scart to component convertor, so I am seeing the image OK. I have changed the G70 to input from sat receiver RGB and output to HD. The image is not bad but I wondered if I could make it better. Sorry to all of you (particularly if you know me!) for this basic question. Normally I would fiddle with this myself. However I have had the G70 set up by the excellent Dr from USA and I am worried about undoing all the careful work that he did. Thanks in advance.
 
Oxhill, can you just confirm for us, you live in
the UK, right?

D-VHS is a Hi-Def source (higher quality signal, sharper image etc etc); and the Satellite system is standard definition which is a much lower resolution signal. It's never going to look as good as the D-VHS no matter which way you connect it.
 
Chris - Im guessing this guy is USA based......

Now we are getting somewhere......Component output from your sat box (that is NOT the same as composite as mentioned in thread 1)

Are you saying that sat is not as good as D-VHS - if so then you are right and as Chris says, it will never be as good.

there is a chance that as you have changed your input equipment (d-VHS to SKY) that you will need to tweak the convergence for that input.......this could also be the cause of slight loss of sharpness as the conv. might be out.....

This is just a guess.....

Any one out there with a G70 got the answer ???
 
I am indeed in the UK. I realise that the output from the D-VHS will much better than the satellite. I just wondered what was the optimum settings for satellite output into G70? Thanks to you all for trying to help.

Hi, Im still trying to understand what is going on here......

So G70 component input - sounds possible (I dont know a G70)

Scart to component convertor - this is possible - BUT the fact that is has red green and blue phono sockets does NOT make it an RGB device - Component and RGB are different (I mention this as there was confusion in the first post between conmposite and component)

G70 input set to RGB - thats NOT component that is RGsB - with sync on Green.

Output to HD - do you mean the sky output has been set to HD? - I did not know this was possible......

To me there still seem to be some confusion in what you write...........It may be that you have the best picture possible but that you are maybe not using the correct description for each item.....

A picture of wach item - outputs and menus would really help here.....I think you sound like you have a good picture and that maybe there is actually nothing wrong......



I think maybe you are using Scart with RGB output to go into RGsB of the G70.
 
Oxhill, the best quality signal coming out of the Sky box is RGB. Use that if possible. However, it is only a basic interlaced signal so you are going to see a lot of scan lines compared to the D-VHS signal.

If converting the RGB to Component makes the signal easier to handle then so be it. If the convertor is good then the two signal types will look very similar. This doesn't change the fact that the signal is still interlaced though. You'll see scan lines.

You say you have your projector set to output HD. How? Is there a scaler built in to the projector or do you have an external box that processes the picture signal?
 
Indeed the great Dr Phelps. Thanks again for all the input. I suspect that I have it as good as it is going to be.

From your first post it certainly does not sound like it and if William Phelps did calibrate the unit for DVHS, it most definately is not for your Sky box! Also dependant on how long ago it was calibrated, it may very well be out of convergence etc
The G70 should be set on standard component input Y, Pb, Pr (if you are actually converting the the RGBS output of your Scart socket correctly to component). Unless you are scaling this signal to a higher resolution (e.g 1080i, 720P, for which you would need an optional progressive scan component board), you would see 576 lines of resolution which unprocessed would look pretty horrible.

My advice to you would be to purchase a reasonable scaler (Lumagen/Crystalio) and get a professional installer to calibrate it and your G70 to your input sources.
 
I am very grateful for everyone's input. I realise that this was a very basic issue. As I hope I explained, I was only neurotic about getting the manual out and giving it a go myself because the excellent Dr Phelps warned me that the G70 was a complex beast etc. I get a reasonable picture at the moment. Of course any recording I make I can then play through the HTPC and the image is spectacular. I love my G70 but rumour has it that the Sony Ruby is an awesome bit of kit. When my G70 finally gives up the ghost (hopefully a long time yet) then at least I have a vaguely economic high end replacement option. I had better start saving. I do think that this is a tremendous site and I know all the hard work that Stewart puts into it, together with all the excellent advice from the members. Thank you all again.
 
Hi Oxhill, I was only trying to point out that this unit provides an awesome picture, but needs to be set up correctly. I'm sure there are others here (I know of two G70 owners of the top of my head) that can reassure you that the G70 is NOT a complex beast, but with a little time and patience and help from members here, you can infact become fairly adept with the setup of this machine.
I also think that many here can achieve and better the results from these projectors over certain 'specialists' in the field.

All the best!:thumbsup:
