content: Or change the channel.Fiddle with the fine tuning.Fiddle with the color.And perhaps the tint too.NTSC = Never Twice the Same Color.

I bought the Sams Photofact and the adventure began....NTSC has a problem with flesh tones, or did the last generation of analogue sets here in the states no longer had those issues. What I hate about PAL is the 50HZ refresh rate, I cannot watch it for more than a few minutes a time without getting a blinding headache. I don't see how the rest of the civilized world could put up with that.The colors were nice, I'll admit that, but not at the expense of a slow vertical refresh rate.

If you'd never encountered a TV, monitor, cinema, AC powered lighting etc you'd notice the flicker of 120hz sets just as bad as you did with 50hz and everywhere with any AC lighting would look like a rave to you. After a couple of weeks not been around anything with a refresh rate lower than 120hz street lighting and friends house lighting gives me headaches. Doesn't take too long to adjust and not notice it again though. At most a day.I can remember deinterlaced PAL 60 been the "gold standard" for (non PC) gaming for a few years and it looked amazing. PAL colour and resolution with the only thing NTSC was better at thrown in. Looked much better on widescreen sets than either other option too. Unfortunately most TVs couldn't handle that until it was too late for SD content.

content: Quote from: Mechanical Menace on April 20, 2016, 05:21:58 pmI think you are making a few too many assumptions in your above statements.The 60HZ doesn't have the same effect on me, I don't get headaches from it. Even after watching PAL in Asia for 28 days I still had headaches.We (over here in the states) don't have lights that flicker at power line frequencies except for the old style florescent tubes, incandescent bulbs don't flicker at 60HZ lone frequencies. They DO at 50HZAnd by the way;I have shorter than average visual persistence.A blessing to be sure.We are all a little different.

content: Quote from: Mechanical Menace on April 20, 2016, 05:21:58 pmPAL resolution isn't really that bad--remember the extra horizontal resolution of Digital HD is spread over a larger relative distance with 16:9 compared to 4:3.SD is about the same as PAL,in any case."Simple PAL" without the delay line could perhaps look to have poor vertical resolution.It was never sold in Oz,& the Colour sets I saw in the UK all were the delay line type as well.Line Structure is another thing ---with reasonable sized screens at a normal viewing distance it wasn't visible.Only a generation of kids who grew up sitting about a metre away from the screen started to notice it.In any case,the technology to artificially double the scan ratewasavailable,& made it much harder to discern line structure.In the early days of analog TV,on air staff were well aware that wearing patterned clothing like "hounds-tooth checks" was a "no-no",as you got nasty strobing effects from interaction with line & field rate scanning----it was even worse with colour.At some time this wisdom was lost,with some horrific results in the last few years of analog.Digital has its own problems,like a presenter in a red dress standing in front of a red background.She looks like she is growing out of the background.

Of course I was born well into the age of SoC based TVs, often with digital controls.Anyway, the earliest sets, supposedly decoded the signal fully, pushing just a little further on the CIE scale than conventional I-Q color detectors. This of course was possible, in part, by the tremendous retail price on the earliest sets, which used something like 30 tubes in them!Tim

When I was lucky enough to get my first dedicated colour monitor I was POSH lol.

The last fully analogue TV I had (a solid state Zenith) I had for fourteen years, it was six years old when I acquired it. It had a very good picture but required maintenance twice a year to keep the picture quality up to snuff. It was a good set, I finally put it to rest in 1996.
