RGB on Sony TV
(Click here to view the original thread with full colors/images)

Posted by: dickuk

I have a Tivo running V2.5.5 connected to my Panasonic digibox and my Sony TV, however when I turn the TV on and press the Tivo button the TV switches to the External (Scart) mode, but it doesnt select RGB, only compostite. Therefore I get a shadow on the display. If I then press the Ext select button on the TV remote, it picks up RGB and the picture is perfect.

I have tried changing scart leads, but to no avail.

Does anyone have a similar problem or a fix?

Also, is there a way to find out how much of the hard drive is used?

Thanks

Richard

What model is the TV? Have you looked through the menu? Some of the more recent ones allow you to change the seetings of the input so you don't have to cycle through them (AV1, AV1 RGB, AV2, AV2 S, etc.).

If you have a Pronto or remote with macros, you could get around it that way.

I have a Sony TV with the same setup. My RGB picture is perfect as it it - I don't need to select the RGB input. The autodetected input (AV1) is fine.

My TV is KV32FX20.

I have a KV32WS3D here - I had to select RGB as input signal in my setup menu.

Which model is your TV?

Posted by: mrtickle

Almost all Sony TVs behave like this, but it's not a problem because already mentioned - the "AV1" input (when auto-selected) actually is displaying RGB.

You can test this by using TiVo's menus to change to composite and back to RGB, and observing the difference onscreen.

My TV model is Sony KV-X2982U (29" 4:3 screen).
I have checked the menus and cant find anyway of changing the order of the external inputs.

When I connect the Sky Digibox straight to the TV, RGB mode is automatically selected.

If I let the Tivo select the ext source and I manually select Composite or RGB then I can see a difference (a shadowing on the composite, but perfect on RGB).

My model is the 32WSD3. Just checked my menus. If it's anything like yours try the following:

go to "Preset" ,
then "Installation",
choose "AV preset",
check "AV1".
By pressing "ok" you should be able to change your input source from "A/V" to RGB.

Hope this helps...:)

Thanks for the info, but I dont seem to have that menu, I get preset, but no installation menu.

i have the same TV :D

to set it to rgb permanently heres the steps....

1) menu, hit ok

2) preset, hit ok

3) manual programme preset, hit ok

4) just hit ok for until you get to the "ch" column and then you can then use up and down arrows to shift this to RGB or AV1....which ever...then hit ok...hitting menu should drop you straight out once you've set it

but im lost with this RGB thing.....can someone explain to me which mine should be set on for the best quality?

i have an scart to scart lead from my tivo to my red scart socket (i understand this to be the better one for some reason)
my tv says AVI, but when i switch it to RGB i get a blank screen (with sound)....is this something i need to set up on the Tivo?

Posted by: Tom123

In order to use RGB for best quality you need to set your TiVo to output "RGB and PAL".

Go into "recorder & phone setup",
then to "SCART settings"
change "video output to tv" to "RGB and PAL"

What system do you use: DTT, Sky, terrestrials only ?
If you you have a set top box, you'll need to channge its output to RGB mode.

Cheers,

Tom

1stthingthatcameintomyhed,

I have tried the procedure you said, and it seems to set RGB to a channel number, but I still get AV1 (composite when pressing the tivo button).

See what you get once you have changed your Tivo output option to RGB and PAL.

Thanks

Richard

i've just done it here....

heres how my line reads in the setup on the telly

Prog=7 (but thats irrelevant)

SYS=EXT

CH=RGB

Search=off

all the others are irrelevant

seems to stay on that just fine once i hit ok....:)

but i dont know about you but AV1 looks sharper with less colour "smear" than RGB...i may switch back i think...

PS tom im on terrestial...cheers :D

Yup, that would be my guess. I have my scart in the black "AV1/RGB" input.

Posted by: 1st thing

just checked....i haven't after all...its in my standard black socket....

im using QED scart cables so i dont think theyre the problem....

oh well perhaps its a personal choice thing...

Posted by: Tom123

Sorry I can't be of any more help :o
Anyone else ???

You need to not only set TiVo to RGB, but you must turn SCART control ON in TiVo's menu. And connect it to AV1 as you are already doing. (Sometimes TiVo has needed a reboot to get the options to "stick")

If you get a picture on the AV1 input, but a black screen (with sound) when you switch it to RGB, it means that the TV isn't receiving the RGB from the device.

HTH - it really is far better to use RGB if you can get it working!

Composite inputs (and thus also aerial inputs) on Sony TVs suffer from what Sony calls "Scanning Velocity Modulation". The scanning beam is artificially speeded up and slowed down as it travels only each picture line, to try and "sharpen" edges. This results in a mess, which you are used to. You can turn it off on composite by switching to "movie" mode if your TV has it. For some reason, TV manufacturers trumpet this feature as a benefit when it isn't (it's just a way of making low-res tubes look sharper in a very fake way). Other manufacturers do it too.

RGB mode on Sony TVs have SVM off permanently. When you see it turned off for the first time, the picture looks "blurred" but it is in fact, correct! There is far more picture detail with SVM turned off which you can never see if it's on. It should be very obvious when you compare the lettering on TiVo's menus for example.

genius mr.tickle..:D

i dont think my sony has a setting to turn it off :(...so i'll probably stick to composite then as tivo is the only device i have that supports rgb, my dvd being to old to have anything but svideo. Having been watching this set for the last 7-8 years i've got really used to it and RGB is taking some getting used to. Oh well...

its a pity sony tvs last so bloody long, i've got another little portable thats 20 years old and still looks good, i'm gonna be an old man by the time the 29" dies and gives me an excuse to go widescreen....the trials of life huh

Do persevere, it's well worth it! Your TV does turn SVM off don't worry, all Sony TVs turn it off in RGB mode (you won't find it in any menu options anywhere). You're missing out on a huge amount of picture detail and colour bandwidth if you don't watch in RGB ;)

my main TiVo is plugged into AV2 on my telly as this allows Smartlink to work for the VCR. I noticed the other day that TiVo 2's menus are considerably brighter than TiVo 1. TiVo 2 is plugged into AV1. I have both set to RGB and SCART control on, will try changing some other settings in case something like Movie is sticking on AV2 or something else is incorrect.

Normally only AV1 is an RGB SCART and AV2 isn't - hence the picture quality difference you are seeing.

Is Smartlink of much use now you have two TiVo's? I never used such things when I didn't have TiVo.

Posted by: 1st thing

yep...on my sony av1 is rgb, av2 is normal or svideo scart....

oh well, i guess i must be just too used to the sharpness of all the other inputs...

Posted by: mrtickle

Remember that that "sharpness" isn't really there; it's artificially added by the TV end and you end up removing picture detail.

Posted by: GarySargent

Not sure about that MrTickle - RGB seems MUCH sharper than composite. I switched to composite yesterday and though how blurred it was.

Posted by: 1st thing

hmm...exact opposite for me...everything but RGB is very sharp, so sharp i can see the scan lines..rgb is less so but edge sharpness is also less...

I've never found that to be the case in any TV I've seen - usually RGB is always better.

Maybe one of your guns is slightly misalligned?

Maybe if you post your model number someone else with the same TV would report back how their RGB fares.

Posted by: 1st thing

Sony KV 2972U

i wonder what other people think....even the text on tivo is less sharp...it may be smoother in rgb, but sharpness is definately less

Posted by: iankb

I've seen at least two older Sony TV's where RGB is definitely worse. It is better on my newer Sony.

To say that RGB is always better is definitely incorrect - it has the capability to be better.

Also remember that RGB is only as good as the cables you run it over. I know that RGB is more susceptiable to noise on the line.

I have read elsewhere on this forum that replacing the supplied scarts with better quality scarts will make a lot of difference.

I have just purchasded three new HQ scart leads and will report back
