Screencast - no sound and low quality image issue with Mi TV 4 55" - LG G7 ThinQ Questions & Answers

Hi My LG G7 connects easily enough with my Mi TV 4 55" over Miracast but image quality is terrible with no sound.
My other Oneplus, Apple and Mi phones have no such issues with sound and image quality being exceptionally clear when connected to the same TV.
Any help would be appreciated. Thanks.

Yeah me too. Have g7 and miTV 32 inch. Low image quality and no sound

[Q] terrible sound quality when plug in ear phone on tab s 8.4

Guy, this is my 1st tablet.
Imainly use this tablet for video, however i experiance the sound quality was really terrible when plug in ear phone, the sound quality was like a mono output and cant clearly differetiate treble and bass.
I though this is the flagship tablet by samsung and carried the s title and it should behave like a high ebd device.
Anyone can advise on this or can advise on the audio chipset that this tablet use?
Solved after restart the tabelt

Asus Zenfone 5Z audio DAC performance?

Well it says that it supports Hi-Fi audio. But how Hi-Fi is it? What DAC is inside? In particular, I would like to know how the sound quality is from the 3.5mm audio jack compared to Hi-Fi mode of LG v30, my current phone. I simply cannot get a phone that downgrades my audio experience, you know?
Even I am interested in this. The specs talk about Hi-res audio. It has Dual 5-magnet speakers with dual NXP smart amplifiers and PMIC internal dual amplifier according to the specs. Does it really have a DAC or does it only have amplifiers. How is the sound quality. I would really like somebody to post their review.
DAC Performance
I don't have technical details on the DAC inside, and I have don't have v30 to compare, but I can tell you that the sound quality combined with DTS is amazing.
I am quite an audiofile and I was impressed with the sound quality. I don't like the bundled earphones unfortunately. I used my BT headset.
I have a P20 as well, which is a much more expensive phone with a DAC, and 5Z's sound quality is comparable. I love P20's headphones though.
The most important and the best thing about 5Z is that DAC/DTS works for bluetooth headphones as well. I have not seen any phone having this feature (may be S9, but I don't know). With phones such as OP, I had to root and use Viper4Android to make by BT headphones sound better. Now, with 5Z, I can keep my phone unrooted and enjoy the great audio experience.
Unfortunately, I don't like the UI and animations of 5Z, and I would use a custom rom when available. I am sure such roms will come for 5Z because with such high-end specs and aggressive pricing, many developers would buy this phone
Cheers

The sound is good but not on par with LG g6 for example. LG is way ahead in the sound part.

I have both LG g6 and g7 but the Zenfone 5Z's sound is the best!!
5z doesn’t have any dedicated DAC as per few video reviews beebom or igyaan audio quality and amplification via headphone jack is not that great. I have a v20 with root and high impedance mode always on. I don’t think this phone compares to any of the recent LG flagships in terms of audio quality.The only place where 5z beats LG would be in the loudspeaker setup where 5z has stereo setup.

I sincerely hope you weren't serious when you said you are an audiophile!
First of all, you can't rate any phone's DAC or AMP performance by using BT headset. Bluetooth headphones have their own inbuilt DAC that they use to process sound when they receive audio in the form of digital signal via Bluetooth from the phone. Then by using their internal inbuilt DAC they convert that Digital signal to Analog signal.
Second of all, are you even serious when you rate Huawei P20/P20 pro sound as great ? Huawei/Honor phones have one of the weakest audio performance out there. Puny amp, okayish DAC, nothing more. Similar is the case with P20/pro.
"P20 is a phone with a DAC !" Which phone isn't the one with DAC? Every phone has one. Some use inbuilt one inside their processors, some employ custom ones for better sound fidelity.
"DAC/DTS works for headphones too!" DAC doesn't work for Bluetooth headphones, it's just that 5z allows to change sound settings of Bluetooth headphones from phone's stock settings. It by no way means that phone's DAC is being involved in Bluetooth headphones. It's simply not possible.
And DAC and DTS aren't the same things either that they can be written interchangeably.
I hope it helps. I by no way mean that 5z has bad audio quality but just corrected some of the things that weren't correct.
I frequently use aux in my car and this is the first device that doesn’t make distortion in sound during high volume. I love it. My car sound system is like concert place now.
The whole Hi-Res audio thing is mainly just marketing and playback support, less to do with the actual quality of the DAC and amp. Nowadays most smartphones can play 24-bit audio at high sample rates (eg. 192kHz). Sony marketed that for many years but their phones kept using on-board Qualcomm DACs with low output voltage (~0.35V from Z5 to XZ Premium). I have the Z5 and I think it's audio quality is good for IEMs but it can't drive some larger headphones very well.
ASUS says there's smart amplifiers but those seem to be for the speakers rather than the headphone. PhoneArena did a review recently and measured the output voltage of the headphone jack to be only 0.252V! That's even lower than the Sony Xperia XZ Premium (0.36V). Of course it's not the end-all, but a higher output voltage would be better at driving higher impedance headphones.
Some users talk about EQ modes sounding better but these things can't improve the quality of the hardware's output (eg. distortion and stereo crosstalk). All they can do is alter the tuning to your preference.
The DAC on the 5Z is just ok ; not audiophile grade by any yard stick . It struggles with high impedance proper headphones like ATH
Which ATH do you have? I had MSR7 and the Xperia Z5 (0.35V) was good enough to drive it for most songs. Does it hiss with low impedance IEMs? Do you hear any distortion or stereo crosstalk? Hopefully someone does measurements...
How does it perform compared to Xperia Z5 to XZ Premium?
I am currently having Sound Magic e80c earphones which have impedance of 64 Ohms. Can one confirm whether it can work on 5z? Currently I am using it with Oneplus One and it works fine.

You will be disappointed. As the output voltage is quite low, this phone isn't capable of driving high impedance headphones.
It's a shame that Asus is making fool of people in the name of "DTS headphone". I have e10C and I have to take the volume all the way upto 100% for movies.

Yeah the DTS headphone X is a gimmick ..
I think there is presently no phone in the market which will come near LG V20, G6, V30 and G7 headphone audio performance, particularly with respect to driving high impedance ear/head phones. Actually, I am searching for another brand other than LG which will give a similar high end audio performance. I have a V20 and partnering that with my Sony MDR 7506 headphones or Venture Electronics MonkPlus earbuds (both having impedance around 60 ohms), the sound quality is awesome which I never found in other smartphones.

Just sold my LG v30+ due to screen ghosting issues and bought the 5z.
The DAC is good for headphones.
I confirm my 5Z can drive my Sennheiser HD58X Jubilee(150 Ohms) when the volume is at 95%.
The sound is not as good as my LG V20's Quad-Dac though.
All these phones are nothing compared to a vibe p1 on resurrection remix
I have LG v20 and in the hopes of gettin listening to mind-blowing awesome sound, I bought FiiO music player and I couldn't get satisfied on anything. Poweramp on LG always destroys low end or certain frequencies (usually male voice) when pushed a little hard and when not pushed, there's no low end to talk about at all. FiiO has no low end frequency at all.
The only thing that came have a little satisfaction was my good old Lenovo Vibe p1 on resurrection remix. Seeing how you guys are rating LG v20 as great or the best, is there something I'm not doing to get the best out of it? I've tried it on earphones, Bluetooth etc but it just doesn't cut it.

May be it can drive .. but I find the audio fidelity not that great compared to even the A1 . Music just doesn't sound wholesome .

i owned lg g6 and the 5z audio quality is not that bad by any means, it's quite OK by 2018 smartphone standard, with it's gimmicky features such as dtx, hi res audio support , etc.
the LG quad dac is the king in the smartphone audio for now, but again, the 5z audio quality is not bad, unless you are very picky about audio quality,
even lg g6 / v30 dac chip still can't compete with my iBasso dx150.
if you never use a true hi res audio player before, the 5z audio quality will be just fine for you.
even for me imho, it's good enough.

sound quality

Hi, I just got my phone, and it has low sound when playing media and with distortion, could it be that my unit is faulty?
Sound quality through headphone jack is good to me, its stereo speaker is fine. I had a lenovo vibe x3 which has same DAC chip as LG V10 and i think mate 20 sounds better. And louder too. But my mate 20 has yellow tint issue on half bottom display, like top is cold but bottom has warm color. How about yours?
Speaker is trash, compare to Mate 9 and Mate 10.
Can anyone tell me what sound quality is like out of the speakers. Don't mean headphone jack just the speakers themselves???
Thanks

I now have Lenovo Vibe X3 and I'm thinking about buying Huawei Mate 20 because of its screen and battery. But sound quality... Are you kidding??? Mate cannot sound better just because Lenovo Vibe X3 has a dedicated sound guts (one of the best implementations of mobile DAC and a couple of amplifiers) whereas Huawei - not. There are sound labs test which tested Huawei. And it's not a musicphone. FOR SURE...
listening in Neutron app (both phone support hires) with same headphone (Fiio F9 pro) gave me that personal opinion, yeah im not kidding when it comes to music. gsm tested same dac for different result (kirin 970 and 980 using same dac) and what make that mate 20 sound lab test result was bad for listening to music. at the time i bought mate 20, i considered note 8 exynos version also, had brought an earphone to test both and bought my first huawei in the end.
Que DAC de audio tiene el mate 20? Es "HD"?

Works in HD mode with good headphones, i dont had problem with sony WH-1000XM3 and poweramp paid and beta version, getting 96khz, 24 bit of output with codec ldac bluetooth, with cable u ll get 192khz
mate 20 speaker sound a bit poor compared to mate 10 or even mate 9 ,
Not a lil bit, really poor compare to Mate 9 and 10
Use this App it's work with me to boost the sound.

You can not boost the sound because the hardware is trash.

Poor Movie Quality When Viewing with USB C to HDMI Cable

Hello everyone,
I watch movies in the bark yard on the big 120 inch screen using my Note 20 Ultra 5G phone connected to a Optoma HD143X Projector using the USB C to HDMI Cable.
The colors tend to come in overly saturated, the darks are dominates on the projector screen.
This is not an issue when I am viewing DVDs or Blue-ray off the Sony UBP-X700
When I look at the Phone screen, the images are sharp & clear, perfect DVD / Blu-ray quality.
Why do you suppose that there is a difference in image quality with viewing movies with the USB C to HDMI Cable ?
Has anyone else had this type of issue & if so, what is the workaround?
Video enhancer was enabled, but that probably only works on the phone screen, not the TV or Projector's screen

Try turning off video enhancer under settings --> advanced features
Thanks digitaljeff, I will give it a shot next movie night & will chime in once this has been achieved and give you some feedback!
If you need a work around, use a device that accepts dlna protocol and send it wiressly from phone. Best quality

Terrible sound quality when broadcasting via BT

I found that the Mi10T has a terrible sound quality when I pair it with a quality speaker or even my car audio system.
It all sounds like it's in a bathroom, for a lack of better description.
I've compared the same music files with a different phone and it's clearly the Mi10T fault.
I was wondering if anyone knows about this and have a solution.
