HDMI v SCART colour
Have calibrated my LCD TV for grayscale and colour with HDMI input from Sky HD box via Edge scaler.
Results are fantastic but when i record (obviously in SD) the picture is very red / pink. The Scart picture also is this colour so not the recorder. It seems the original settings on my TV were the best compromise between Scart and HDMI but my calibration has skewed it. Blue Ray and DVD (also HDMI thru the scaler) are also great I assume i will have to live with incorrect colour from scart source? Is this normal or can i improve the scart output? |

Make sure the scart cable is connected correctly at both ends and try another scart lead. My THOR scart lead recently developed a fault giving a red picture!

Now the settings used for replaying those recordings via a different input like scart will have an affect on what they look like. Does your TV allow you to have different settings and save them for individual inputs? Might just be a case of adjusting the user settings for the scart input. If the recordings were fine before the calibration I can't see why they are not now. Could be a bad connection or a faulty lead as mentioned in an earlier post. |

Have had my Pace HD STB recently replaced by Sky for an Amstrad and of course i didn't check the Scart connections. It wasn't the lead at fault it was a faulty connection ie not firmly pressed into place at the STB. My experience of Scart leads is that one loses either total sound or total picture and not the fault i reported (so much for my experience). Things are now back to normal thanks to members of the forum and i apologise for bringing this fundamental error to your attention. |

How did you calibrate - i.e. what gear/software/disc etc?
How far did you go when calibrating - contrast, brightness, colour...or RGB / x.y.Y with a probe? I did the usual greyscale and colour calibration using a laptop, Eye One Display Lite and ColorHCFR software (can't afford the Calman). Then calibrated using a mixture of built in test patterns in the DVDO Edge, a purchased DVE HD Blue Ray disc (despite its absence of individual colour patterns) and the most useful of all a downloaded Test Pattern disc AVS HD 709 free from the AVS forum. This was great for not only colour calibration but having flashing bars to get correct contrast and brightness settings at their extreme ends where perhaps the Eye One is less capable. Its only problem to me was the inability of my Samsung 1400 to read the AVCHD on the DVD I burnt (later versions work apparently). Solved this by extracting files from downloaded .iso and modifying them to get my 1400 to think it was a Blue Ray. Obviously adjusted RGB via lowend and highend in the Service menu for the greyscale and am lucky to have a set that allows CMS adjustments of all individual primary and secondary colours. When adjusted via Eye One colour was easy to adjust and not many backwards and forwards adjustments were necessary before i got an acceptable deltaE. I was not very happy with the whiteness / blackness so found the AVS disc brilliant in getting exactly what i wanted. Obviously this calibration is from the Blue Ray source but i am finding very little variation when switched (via the Edge) to Sky STB. No need to adjust on the Edge. This is surprising considering problems people experience re contrast sticking matters with Amstrads (perhaps i am lucky). Also no adjustment needed when played via my Oppo 980 Dvd player. Sorry for the length of this post hopefully i've answered your queries ? |

Can someone please explain what this is all about? I have just bought a new LCD set and don't understand why this is necessary. I thought that any colour display that showed a good black and white picture would display good colour. Well it did years ago and all this sounds a bit like the adjustments required on the early colour sets of the 1960s.

You can have it done professionally or buy one of the various software packages/optical lenses out now that allow you to do this yourself. The optical lens takes readings off screen and displays them on the PC, you then make the critical adjustments. You are adjusting the guts of the display, not the basic user settings. Calibrating a display this way can really improve the final picture you see. |

Thanks - will have a go if the kit is not a silly price!

If you can adjust the colour level via the SCART input then there's probably a colour decoder circuit operating in the TV. This will have have 'red push' to counteract the overbluing of skin tones. Once the blue bias is removed then the red push becomes quite obvious. As others have said, have a look if there's an input memory associated with the SCART input. Alternatively see if there's some way to get in to the service menu and dial back the amount of red push. Regards |

The final picture usually does look quite red by comparison to the overly blue image that all TVs are set up on. Unless there's a colour decoder in the chain though it's often a case of seeing accurate colour balance for the first time. This might be the case in your situation.

Alternatively see if there's some way to get in to the service menu and dial back the amount of red push. Regards Adjusted the low and high end red, green and blue during greyscale calibration (obviously using Service Menu) and individually adjusted R,G, & B together with individual secondaries on the TV for colour calibration, (thank you Toshiba for the CMS). In fact am now happy with the Scart picture colours as a result of my previously admitted faulty lead being properly seated in its socket. I'm so ashamed i didn't spot this originally. |
