i saw the Fauser LiFli its about 300 euros but it is not conectable to a pc? The info only comes in the green red bar andby sound right?
It has a mono 3.5 inch audio connector. With a special cable you can connect it to an oscilloscope and use it like a regular sensor. Its sensor is fast and, as depicted in the oscilloscope thread, displays the shape of high frequencies more accurately than the DIY solutions, but can't detect flicker that's about 1% or lower. On the other hand, the DIY sensor is slower but can detect flicker percentages of at least 2 digits after the comma when paired with an 8-bit oscilloscope that has AC mode.
So you bought one and pointed it to the tv，start changing configs until the flicker is low?
Basically, yes. I had bought it to find low-flicker LED bulbs in lighting stores, and now that I already had it, I measured the new TV with it, too. I was surprised when there was a black scene on the TV and the device, which was still active, lying on the table, suddenly started humming. I would have overseen that the TV employed PWM during black scenes otherwise. Something which probably wouldn't happen with OLED TVs though (my TV is a regular backlit one).
The immediate sound feedback really is a helpful feature for fine-tuning settings and brightness.
Do you think this particular device is the best price relation ?
Difficult to say. I think the outstanding feature here is the acoustic feedback, which AFAIK no other device has (only even more expensive ones).
But I also use the DIY sensor (which is like $1 or so). You can assemble it without soldering, if that's your concern. Everything is described in the thread. I would order multiple sensors just in case. They are rather fragile.
I don't know how the Opple compares. If it is accurate and displays the waveform in real-time, then maybe it's enough. The other device mentioned in the forum was the Radex Lupin, but it seems to be very inaccurate, as seen in YouTube videos and customer reviews.
