Any other Hisense 65A7400F user in here having the same issue as mine?
Some images while playing fast-action videos is lagging. Quite badly I say

And it happens all the time, using the built-in Android and even PC connected to the screen

Also, why is the built-in Android in the A7400F displaying at 1080P instead of 4K?
I can only utilize 4K when there's another device connected to the TV through HDMI (PC/External Android Box/PS5)

Bought mine in 2021. If I'm the only 1 having this issue, I still have some time to RMA it

Do you see the artifacts only when watching animes or other fast-moving videos too?
Haven't tried disabling the MEMC, will try it when I get home

The artifacts are really annoying

Everything has some glitches or artifacts here & there
Videos I've played:
1. Movies, Animes & TV Shows played using KODI through network shared drive
2. Anything in Netflix
3. Anything in UniFi PlayTV

I don't have Astro & never will

But they only appeared during fast action scenes. Haven't tried turning off MEMC though as suggested by andrekua2

By the way, can you check if the built-in Android TV on your 65A7400F is also displaying only at 1080P instead of 4K?

Subtitles or not, it's still the same
Don't remember the picture preset, will update later
No. The Google Android TV itself
Having the ability to play 4K video files and the OS itself displaying at 4K is 2 different stuff
Even 1080P screen can play 4K videos too, it's just not displaying at 4K

That was not my intention at all, you just misunderstood my reply
My apologies if you felt that way

Ahh, that explains it
Yes. The resolution on the homescreen and the apps installed
Some apps like KODI has the capability of showing what resolution the OS is running

Extra Note:
I'm not sure if my issue is artifacts or ghosting. Will try to capture some video with my phone then share it here later

Will test it out later when I'm at home

Thank you for the suggestion 👍

andrekua2 was right. Turning off MEMC fixed the issue
Now no more ghosting/artifacts

Thanks bro

My Vinnfier Hyperbar 500 refuses to turn off if connected to my Hisense 65A7400F TV using HDMI ARC
Anyone with the same exact hardware combination has the same issue?

It turns off fine while the TV is turning off but it turns itself back on after a few seconds while the TV stays off

Don't have this issue with my Xiaomi P1 55" & Sharp 4TC60CK1X. Both also use the same soundbar which is the Vinnfier Hyperbar 500

Will test this out. Thanks

Didn't work
I even tried with a new HDMI cable

The only thing I haven't tried is reset the whole TV
Maybe 1 day I will try doing that

Or perhaps the Vinnfier Hyperbar 500 is not fully compatible with the Hisense 65A7400F

Yeah, been using the 3.5mm analog all this time, just wishing the HDMI ARC would work

If only the Xiaomi P1 has a 65", I would trade this TV in a heartbeat

Finally! The issue is fixed by updating the firmware of my 65A7400F manually

A special thank you to stasio for highlighting the firmware update for the A7400F. Was scared at first to run the update because I'm afraid the update will screw up the TV somehow. But alas, the update worked perfectly

Now the ARC function works beautifully, when the TV goes into standby mode, my Vinnfier Hyperbar 500 also goes to sleep

Weird why Hisense Malaysia isn't pushing the L0205 firmware update
My A7400F was previously on K0811

For those who wants to update their A7400F firmware to L0205, here's the actual steps:

Download Link: https://mega.nz/file/wZhVzArS#q5t-1mKlCSjja...0068APS9KAfsZwY

Steps:
1. Download and extract the "upgrade_no_tvcertificate.pkg" file to the root folder of your USB flash drive formatted to FAT32 in MBR partition table
2. Turn off the TV
3. Disconnect the power cable
4. Insert the USB flash drive into any of the USB port at the back of the TV
5. Hold the power button on the remote making sure it's pointing to the TV IR receiver while reconnecting the power cable (might need help from another person for this)
6. Wait until the update process is complete. It will take a few minutes

Owh and a special reminder to all: The firmware update will reset the TV. Everything you've installed/downloaded into the internal storage of the TV will disappear

Important Note: The firmware update is only valid for Hisense A7400F TV with this service code:
HX65A6106FUW

Special Note: I am not responsible for any damage that might occur. Run the firmware update on your own risk

Wait, there's a L1211? Can you share the download link?
I tried looking at the 4PDA forum but couldn't find the download link for L1211

Anyone tried doing warranty claim for their Hisense TV?
My 65A7400F is showing green lines at the bottom of the screen

Bought in February 2021 so by my calculation, it still has warranty until February 2024 since Hisense provides 3 year warranty for their TVs

Not really. My living room TV is rarely used
We only use it when having dinner/breakfast/lunch

After finished eating, we turn it off
Rarely use the TV for long period of time except when people come to our house

Damn. My 6 years old Hisense 58" K220P that was purchased in 2017 had zero issues until today despite being abused alot more
Previously used for my master bedroom to watch movies every night then I gave it to my in-laws who had nothing to do all day besides watching TV and it's still working fine until today
No dead pixel, no green lines, no nothing

Waiting for the seller to provide me with an invoice since I bought the TV through Shopee but the seller said he will provide an official retail shop invoice so I can proceed with the warranty claim

No retail shop invoice: 2 year warranty
With retail shop invoice: 3 year warranty

Strange la Hisense

Just got the invoice. Will proceed to do warranty claim for my A7400F now
Very good after sales service by the store. Will definitely buy from them again
Purchased in 2021 and they still entertain invoice request

Wondering what would they replace it with
Hopefully not any TV with the VIDAA OS. I need Google TV

Hisense just came today to deliver the replacement TV
They replaced my faulty 65A7400F with 65A6500K

Not sure if it's an upgrade or downgrade but so far I'm liking it

Features that I liked on the A6500K that was not present on the A7400F:
1. Built-in Hey Google capability makes things a lot easier. Now I don't have to press the Google Assistant button on the remote to use Hey Google
2. Built-in Apple AirPlay & Apple Homekit feature. Very useful for Apple users like me

The sad part, it's still running on Android 11, instead of Android 12/13
Which means the homescreen is still displaying at 1080P
