Hopefully this helps other owners, and I'd be interested to hear what settings work best for everyone else. Let me know if I must test something specific?

I've recently started testing the new RockTek G2 Next and wanted to share my experience with Dolby Vision, Dolby Atmos, audio passthrough, and different streaming apps as several people have requested more information about this device.

The device works very smoothly and is easy to navigate if you are familiar with the Google TV platform.

MY SETUP

• Device: RockTek G2 Next (2026 model)
• OS: Google TV (based on Android TV OS 14)
• TV: Hisense 65U8K (4K TV with Dolby Vision + Atmos + eARC)
• Audio: Sony HT-G700 (Soundbar with HDMI eARC)
• Connection: RockTek → Hisense TV → Sony soundbar (eARC)
• Network: Wired Ethernet
• Media Server: Plex
• Apps tested: Plex (Latest), Plezy 2.22 (MPV), Netflix and Prime Video

AUDIO SETTINGS (MANUAL WORKS BETTER)

Initially, Audio Format selection was set to Automatic.

My Sony soundbar mostly displayed LPCM on Automatic.

After changing Audio Format selection to manual and enabling the supported Dolby formats, I noticed a definite improvement as noted below:

Plezy 2.22 (MPV): Dolby TrueHD and Dolby Atmos working perfectly in my tests. Best player so far!

Plex 2026.20.0: Dolby TrueHD not working and Dolby Atmos works inconsistently not as well as Plezy.

Netflix and Prime Video: Outputs Dolby Digital Plus (DD+).

VIDEO SETTINGS – NO DIFFERENCE

I tested Video Format Selection on both Automatic and Manual.

Unlike audio, changing video to Manual made no noticeable difference to HDR or Dolby Vision playback.

I also tested Dolby Vision Source-led versus Device-led, without noticing a difference.

My preference is therefore to leave Video Format Selection on Automatic.

Plezy 2.22 (MPV): Dolby Vision works perfectly on all videos I tested on it.

Plex 2026.20.0: Dolby Vision works inconsistently not as well as Plezy.

Netflix and Prime Video: Dolby Vision not working. HDR10 and HDR10+ only.

These results are based on the content I've tested, not every possible format.

Important Plezy discovery:

I noticed that during camera panning, the video would sometimes freeze briefly and jump forward every couple of seconds.

After testing different settings, I discovered that enabling Normalize Loudness in Plezy was causing this problem. Disabling Normalize Loudness resolved the stuttering.

Quite surprising that an audio setting could affect video smoothness!

My Conclusion

The new RockTek G2 Next looks promising, particularly when it comes to Dolby Vision and TrueHD Atmos playback.

Overall, Plezy with MPV performs considerably better than the official Plex app. I've successfully played Dolby Vision with TrueHD Atmos without any issues using Plezy, whereas Plex remains inconsistent.

I'm no expert, but if Plezy can handle these formats perfectly on the same device, wouldn't that suggest that at least some of the problems are related to the apps and their playback engines rather than limitations of the RockTek hardware itself?

I'd be interested to hear what other RockTek G2 Next owners have experienced, whether you've encountered similar issues, and if you've found any better settings or fixes.

I have had a Google TV Streamer 4k for almost a year now, and it is driving me absolutely bonkers; the audio loses synchronization all the time. No live sent events ever works, I'll have to stream hockey and footy games to my Chromecast, they are unwatchable on the TV streamer due to sound sync issues. Now content that are not live have begun to show this issue as well, sometimes it works by restarting the machine but then the problems comes back in a day or two. Is there something that can be done about this?

I have no fancy set up, I am using the TV:s internal speaker. The problem does not appear when using a Chromecast at all.

I'm using the latest version of TiviMate on both devices.

I have a Chromecast with Google TV 4K, which plays some channels at 60 FPS. However, I also have a Xiaomi TV Box (3rd Gen), and the same channels only play at 50 FPS on that device. The playback also seems less smooth compared to the Chromecast 4K.

Does anyone know why this is happening or how I can fix it?

Thanks in advance!
