Television issues and firmware bugs and buyers guide for your next TV

might become this using Frameblending:
A A ab B B C C cd D D

Is it possible to determine this with the testfile I created and posted here which is just like rtings do their tests?

I mean do I see this when I create a 1 second photo with a camera which supports shutter speed adjusting that it is displaying A A ab B B C C cd D D

"ab" and "cd" are bad if it is done this way, isn't it?

[huhn]

the camera should fail this test but it seeable with the human eye it's the same as smoothmotion in madVR is better then judder but frame matching still wins.

an ultra high refreshrate camera would show this plus all the others flaws of the LCD based tech.

[VBB]

@Klaus No, Real Cinema is disabled and grayed out when in PC mode, at least on my C7.

[Klaus1189]

What manufacturers do support GSync and/or freesync, so one can also do some games with that tech?

I only know of LG which supports GSync on some models, but not on all?

HDMI 2.1 supports VRR. Does that also help for gaming?

[huhn]

i will see when sony adds it. but it's not named yet.
but on the other hand GPU manufactures can add support HDMI VRR.

[huhn]

just to update. sony well well... 4k 120 is not even close to UHD resolution (not talking about chroma here).

so i guess time to avoid sony for real this time. and i guess it's time for me to join the users that get tortured by LG OLED processing.

wow now i really don't want a HDMI 2.1 GPU...

[chros]

Panasonic also will have hdmi 2.1,who know. maybe they will be usable for the first time? :)

[huhn]

you can't even beat the sharpening filter the last years OLED can't play 23p HDR back without dropping frames.

"every" device will have UHD 120 HZ it's part of an important broadcast standard.

[Ghitulescu]

If the keyword here is "native", then after CRT not a single panel was "native" 24. The most common fps they worked at was 60Hz. All flat panels work with interpolation, to fit 24p and variants into the native 60Hz.

OLED should have had the possibility of being native 24. I don't think the TV makers just flushed all the knowlegde down the toilet to please some purists that most times do not even notice their pet fps.
Maybe someone working directly with panels can shed some light - no brochures, leaflets or other marketing "test reports".

[huhn]

LCD panels are native 120 HZ for many years now.
plasma TVs are using something in the range of 48-96.

sony even figured out hey our TVs can do 50 native for pal so even our cheap TVs limited to a native 60 HZ panel can do 48 which isn't far off.

because a lcd screen is sample hold it's "native".

[chros]

Same with recent LG Oleds (althogh they are far from perfect), we will see this year around april/jun.
Btw if you are not forced to buy a tv "now" and you don't want to throw money out of the window, it's always good idea to buy a prev year model e.g. 1 year later, not just because of the massive price difference but hopefully initial bugs are already fixed by then :)

That's a bummer ... A Sony TV was on my wishlist for the next few months :(

[VBB]

I have my eye on the upcoming G1 now ;)

[chros]

Me on Panasonic :D

[Klaus1189]

But Panasonic can not do 4:4:4 and true native 24p at the same time according to @huhn. I was already on purchasing one, but that is a nogo for my usage. This was also the main intention of creating this thread. But perhaps Panasonic has changed things recently, I don‘t know.

rtings check 4:4:4 and also 24p native, but not both at the same time. At least I couldn‘t find it in any review of them.

[huhn]

no Vincent reported that this intentional issue is still present.
but with 120 HZ you may not need it. but well it Panasonic.
just look at sony what they are doing now...

[Klaus1189]

No VRR update for Sony TVs? Or did I miss another issue?

[huhn]

the XH90 was planned to get it but it didn't yet and that's the only screen that has this planned for 2020 don't forget this Tv can't even do 1080p120 correctly which countless old TVs can.
the new ones are announced with it too.

they have removed this in some countries for the xh90 a short time and it's been over 6 months there is currently no reason to believe anything they say the 120 HZ is a obvious lie.
sony is currently in a terrible position claiming alot and delivering nearly zero promises.
the PS5 can do VRR yet the old XBOX can so can the new xbox both use pretty much the same hard.
the PS5 HDMI 2.1 is extremely limited it can't do RGB UHD 120 HZ it has to use 422 that's below displayport 1.4.

[Klaus1189]

Yes, it was the promised 120fps support, that is what I knew but forgot about. :o
What TV do you look forward? Perhaps the new LG OLEDs? Linus made a short video about "OLED V2", too:

For me it is really hard to choose, I must admit ...

[huhn]

have to see. maybe i just get a cx because it at least doesn't downscale...
but i have to get this TV taken back some how and that's going to be some work because it is ~6 month old.

[Klaus1189]

Sony promised and didn‘t deliver. For me an easy case. Companies have to wake up.

[huhn]

one and a half year after release the TV is maybe able to do VRR at 1080p!

Hello,
Maybe it's a wrong idea to revive this thread but I was too shy to open my own.

I have a question about eARC and was hoping maybe here, with advanced users, some would know.
I have a bad image of AV receivers/processors because of several issues like HDMI handshake (from 2010s), wrong passthrough, modified colorspace, audio delay. That's why I prefer to use HDMI from PC to TV for video, and I use USB for audio.
But I was wondering, thanks to progress, maybe eARC solved these problems ?
I know eARC can't handle advanced audio, but I only need 5.1 lossless audio. Are there people who tried eARC with success (sending 5.1 TrueHD for example to TV) ? Or is it plagued with its own limits/defaults ?

But maybe it's too recent and nobody has eARC compatible TV and receiver ?

[huhn]

do PC -> TV.
and PC -> AVR -> TV
clone the screens and that should be that.

AFAIK which is barely anything eARC can do everything in terms of audio.

ARC was limited to about SPDIF or something.

[pirlouy]

Well, "dual screens" was the cause of problems in the past too. I wanted to avoid that.
Of course if Windows (or GPU) was able to send a black screen to AVR (audio only), it would be nice, but it has been asked for a decade, and I dont' think it will happen one day (don't think it is possible on Linux too).

I know about ARC limitation, but I had hopes for eARC.
