Thanks for that! What do you think off vivid picture mode ?
Vivid is generally a bad starting point for most TVs. The contrast is whacked up too high, the brightness set too low, sharpness is overcooked and there's often a tonne of picture enhancement modes enabled that do more to screw things up than help. Just avoid.... plain and simple.
Some stuff is fairly safe to say "this on, this off, this part way". It's usually the picture processing modes. I calibrate professionally, and what I do with any new TV model I haven't calibrated before is strip everything back to basics, then get the brightness, contrast dialled in for the room, and then set the sharpness for the source. When setting up, I'm either using an external test pattern generator or the customer's disc player if they have one. The sharpness settings are individual to the sources; so Freeview will look different to Freesat will look different to Sky and Virgin and and and ... you get the picture.
Next is colour tone (colour balance: warm / normal / cool) and I'll measure a 10-point greyscale with a light sensor attached to a PC to see which of those gets closest to the ideal colour tracking. Again, generally it's the Warm setting that's closest. After that, I'll do a basic Colour control adjustment so that the set is operating on a neutral basis. Apart from the 10-point greyscale measurement, all the rest of what I described above can be done by any TV owner who is interested in getting their TV to work better than the factory presets and is happy to spend a small amount of cash on a test disc to help.
I can't stress enough how important it is to get brightness and contrast set correctly for the light conditions in the viewing room. Contrast gives us control of what happens in the highlights of a picture. Set it too high and all the lighter areas and detail thety contain gets merged in to one white formless blob. It's the same effect as an overexposed picture. Go too low and the result is a dull looking image. It's why test patterns are really helpful. You see, unlike picture content, which can very from shot to shot as the director instructs the colourist to juggling whether there's detail in the lighter or darker parts of the image because of the limited dynamic range of a video signal, a test pattern is consistent and accurate. Setting the Contrast correctly means that when there's white detail to be seen, then it will be.
The same goes for Brightness, but this one is even more fundamental.
Brightness gives us control of how much or how little shaddow detail is seen, and whether that detail is obscured in a black swathe of nothingness, or if it's all overblown and grey looking in shadow areas because the brightness is too high. The other thing that folk rarely understand is that brightness affects the colour saturation. Set it too high and all the colours look paler and slightly washed-out. Set it too low and it creates too much colour saturation that then affects the colour balance.
Once again then, a test pattern offers a reference standard that's consistent with the broadcast standards that the film and TV companies work to. It also takes in to account the ambient light in a room. This is why you have an
ISF Day and an
ISF Night mode in the menus. There isn't one set of numbers that's universally correct for Brightness (or Contrast). It has to be set for your TV, in Your room, your sources, and for the lighting levels that you have for daytime and for evening viewing. This is why listening to anyone who tells you what Contrast and Brightness settings to use should ring alarm bells. It's the equivalent of that bloke at the pub who thinks he knows everything telling someone the best gear to drive in for their car. Anyone who drives a manual knows that the gear box has a range of settings to suit the road conditions; and so it is with Brightness and Contrast.
Once the basics are done, I'll then use various test patterns to assess the effect of each picture processing feature. This shows me whether they're helping or harming the picture, and if there's levels to a setting, just where that setting goes from being beneficial to being picture destructive. I'll then finish off with a full colour calibration which is what really supercharges a TV or projector's performance. A broad range of the same types of patterns are available on consumer test discs.
Something else to consider is batch variation; even with the same model of TV or projector, set up in the same room and with the same sources, you'll still get some variation in the final numbers. I know this first had because I calibrated lots of the same model projector for a dealer. It's down to component tolerances. Even with as little as a +/-5% difference in capacitors and resistors, you'll get enough difference that no two models of the same set will give exactly the same settings numbers.
If you want your new telly to perform, download the basic AVS709 testpatterns from the AVS forum site, or buy a copy of Spears & Munsil or DVE HD Basics or Disney Wow. The discs will come with the colour filter gel so you can do the colour and tint adjustments. The downloaded patterns won't, so you'll have to forego that.
