HDTVTEST (Vincent Teoh) Discussion Thread

When it comes to HD and 4K signals, setting it to 0 or 10 makes no difference. And even if it is sharpening the image on lower res signals, it's very small and hardly noticeable. It's really just personal preference.

Sorry but I don't really agree with that. It is visible that 10 removes detail, even on a 4K native resolution source. It's not "news" that 0 means "no sharpening" on LGs, it's been the same for years.

"very small and hardly noticeable" is subjective: videophiles do not any processing of the image, so will always set it to 0.

I'm just saying that even the person who calibrated my LG C9 TV from Value Electronics left it on 10. I've even looked at it myself and have seen no change what so ever between 0 and 10, so I have left it on 10 for that purpose.

It's about OLED, and MiniLED.

I can access that TechRadar link now, strange, momentary glitch with their site? Anyway, I’m more liking MicroLED as the big technological step forward –

That's fine, and it is your choice . You can check the differences using test patterns if you're in any doubt. They are clearly visible with the right patterns, such as the "Aspect Ratio&Sharpness" section in Mehanik's excellent free test patterns, which are 4K resolution. Obviously, it is up to you which you use at the end of the day.

I'm just saying that the fact remains, videophiles do not want any processing of the image, so we will always set it to 0 since we know, after testing, that 0 is the only value which avoids artificial sharpening for 4K sources. That's also why Vincent wasted no time in changing it to 0.

Agreed... Any test pattern with 1-pixel wide black and white horizontal and vertical lines can be used to reveal the effects of sharpening...

I can't remember where, but there was a discussion about this a few months ago in another thread and it was agreed that it was personal preference and that for some reason LG's 0 is 10.

I dont believe it's personal preference but dependant on what test pattern they're using and if it's introducing artifacts. I've seen and read calibrators doing either or on LG OLEDs for a few model years now.

[LordoftheRings]

There is a difference between reference and preference; one adds a "p".

Indeed. It's disappointing that there's any doubt about this, especially after I gave the details of the test patterns used to prove it. This is science. It's not about what you "remember", or what you "believe", or what any random calibrator may or may not have done in the past.

It is a fact, not an opinion, that 0 is the only value that doesn't add processing.

The only preference involved is "do I want to add processing or not?". That's a completely different question! If you do, choose whatever value you like! LG's default of 10 adds a little bit of processing and is the default. But if you don't want processing, set to 0. Videophiles do not want any processing of the image, so we will always set it to 0 since we know for a fact, after testing, that 0 is the only value which avoids artificial sharpening for 4K sources. That's also why Vincent wasted no time in changing it to 0.

It's the same with Oppo 103 ... zero (0). ...No video sharpening processing, for true videofiles.

I saw that when he first released it. This is cool; good info we can all use.
I'd rather know than not know.

Best comparison video on the Tubes. How many times is Vincent going to state the price of the reference monitor? Lol

That near black brightening on the AJ90 for me is a real killer. It's definitely not a god tier TV.

So just accept his word without comparing yourself.

I know he uses 1 specific scene from GOT to showcase that issue. However after personally going through close to 50 titles mixed with SDR, HDR and DV presentations I haven't noticed any issues of such on my set.

Dnice (DeWayne) has stated that both OOTB Sony does come out of black too fast while LG comes out.to slow creating mild crush. Might look punchy and inky but it's still crush. So neither set you buy will be perfect, but that both can be calibrated to mitigate those issues on either sets.

Another member on AVS had his A90J just calibrated but Chad B and that the issues wasn't raised by him either.

A few members say they can't recreate this issue to the extent Vincent shows it.
