On getting a new TV

I forgot to say - some things you must do on getting a new TV, whether LCD or OLED or whatever.

Set to "Just Scan"

You need to set the picture to actually fit the screen - HD content is normal now for a lot of sources, especially on Sky TV, and is an image transmitted digitally using 1920x1080 pixels. Your HD TV has a panel that has 1920x1080 pixels. This is no co-incidence! You need the image to fit on to the panel perfectly as designed for the standard and as conceived by the film/programme makers. Sadly all TVs assume you want to upscale the image - taking those 1920x1080 pixels and using algorithms that blur and expand to larger than that, throw away some of the border and then display on your 1920x1080 pixel panel. This is STUPID. Do not do it! Set the TV to "Just Scan" or whatever your model calls it.

Turn off "Vivid"

The TV will be set to show colours really brightly and unnecessarily so - this is for showrooms. Set to display sensibly, or at the very least carefully consider how you want to see the image. Don't just stick to the horrid default that turns people's faces tomato red.

Kill the motion tracking crap

The TV will try and interpolate motion on the 25Hz or 50Hz images and create intermediate images. This rarely works well and often screws up really badly. You brain is far better than the TV at doing this, which is why TV works at these frequencies in the first place. I have no idea why they even try - it is a nightmare. Maybe it works if you watch football, I don't know, but in almost all other cases you get weird juddering effects and heaven help you if you want to read any scrolling text on a news channel!

  1. On the subject of frame interpolation, have you tried SVP on a decent PC? (and, even better, a 120/144hz screen?)

    It's an excellent example of interpolation, I don't think we'll see better until HFR content becomes the norm (meaning we don't have to invent the other frames!)

TOTSCO 66 is guidance, optional

I feel I need to explain this. The TOTSCO call today, first I have been on, and wow! But a key point was TOTSCO bulletin 66, which is actual...
