[Q] HDMI = Laggy Nexus 10? - Nexus 10 Q&A, Help & Troubleshooting

I think my last post got deleted, what did I do wrong?
I recently got a HDMI Micro converter so that I could plug my Nexus 10 into my TV.
Sound and video is fine (changed resolution to 1920x1080), but every game and even most menus are very laggy.
It's almost as if everything is rendered twice!
Games that normally run on high or medium barely run on lowest (Asphalt 8 for example).
But the second I unplug the HDMI cable, everything is back to normal.
I've tried everything I can think of to fix the issue, but I haven't found a solution yet.
Has anyone had this problem and found a solution, or does anyone have any suggestions on what to do?

HDMI-Out - Hands On

So, I just plugged the Xoom into the little micro-HDMI cable (picked one up from New Egg for my Evo) and heres what I found:
Mirror mode seems to absolutely work. It didnt at first, but unplugging it and plugging it back in while the Xoom was on did the trick.
Everything that I did on the Xoom, showed up on my TV and played through the TV's speakers. Switched between homescreens, messed with email, played angry birds, pulled up Google maps, browsed the youtube app/videos, played music (that came pre-loaded) and browsed the pictures in my gallery. I certainly saw enough to believe that "Mirror Mode" means exactly that... and it works out of the box. Audio and all.
Now, there might be a couple of hiccups if trying to play drm-ed content, but I didnt have any to try.
This is what I was looking for. Relieved that I won't have to get the dock as some others said.
I was pretty surprised. I thought it had about a 10-15% chance of working.
Now I just need to get a short-range wireless HDMI transmitter to keep on the coffee table and I'll be one happy camper... that and re-program my remote for quick access.
I'd like to know which transmitter you go with. They can easily cost a couple hundred.
Great news! Just ordered a Micro-D cable, never bothered to get one for my EVO. It will be awesome to be able to mirror the entire UI and contents to any HDTV.
Used the hdmi today but its super unstable. Crashed twice trying to play youtube videos. Crashwd once just plugging it in. It seems to lose tthe hdmi handshake sometimes. I was able to play about 5 youtube videos in a row and then went to click one and it had to handshake again and then crashed

[Q] Netflix video problem with 8.0 help

Do you guys get video stuttering on Netflix? It's pretty bad on my tab 4 8.0 to the point of getting a headache. I've tried 2.4 & 5ghz but no change. Battery saver is off. This doesn't happen on any other android devices I own. Even my old tab 2 runs Netflix smoother. Any tips or is this how it is on all tab 4s?
Could someone try Netflix and let me know how it is on your tablet please.
Tested Netflix on my Tab4 8", no problems at all.
Do you experience this stuttering on any other video app?

Tab 7 here. I get a bit of stuttering but rebooted and plays smooth again.
Sent from my SM-T230NU using XDA Free mobile app
I've tried out some other players like mxplayer and also stuff like YouTube and video playback is smooth. It seems to be just Netflix that is having this issue for me. I've restarted and all that but no luck. Netflix is the only one getting this stuttering every few seconds. Real annoying. Not sure why. I've never seen Netflix act like this on any of my devices and other tablets that I currently own.
Try clearing the cache, try reinstalling?
i have the same problem
what i have tried so far:
1. re install firmware using Kies.
2. format cache, factory reset from recovery
3. clear cache, restart app
4. disabled screen mirror, smart stay, palm motion , switched to nova launcher...
5. limit background process, check do not keep activities.
6. disabled power saving.
7. disabled multiwindow.
edit: also tried
8. clear all other apps cache.
9. Turned off all the bloatware.
10. installed task killers, show no process running since they are Turned off.
11 disabled rotation
12. enabled airplane mode
I also noticed movies in SD does not shutter. only the ones in super HD.
don't know what else to try, and i don't want to root and lose warranty.
playing 1080p 60Hz videos shutter a little bit, I'm starting to think that is just that the CPU cant cope with doing many things at the same time like using wireless an decoding video. since day 1, i noticed that while the updates were downloading and installing it became very laggy over all, and I was like, what are 4 cores there for then? its just that its a crappy tablet and that's all.
I've tried a lot of the things above to and Netflix is still having this micro stuttering. I noticed that if I lower the Netflix quality in my settings it will still stutter so it has nothing to do with the tablet not being able to handle high quality. It almost seems like there's a bug on the Netflix side with this tablet that is causing this or something. It's kinda sad that my old tab 2 7.0 Netflix stream is better than this new tab 4. I also have a shield tablet that just blows both these away but that's expected. My wife and daughter use this tab 4 and they watch allot of Netflix on it so I would really like to figure this out. Anyone else have any ideas on what to do or know if there's a bug that needs to be ironed out with Netflix and this tablet. Maybe there's a update from Netflix or Samsung to fix this problem in the future...if they know about it.

Video playback on Remix - extremely choppy please help before I go insane!

I posted a thread up a while ago about playback being poor on Remix with 50Hz content (mods please delete that thread thank you), but it seems following a recent fresh install that all video playback is absolutely terrible no matter how I approach it.
I use an external WD 2Tb drive which connects via Stickmount. This is working fine for roms and also on other units (Ouya, Rpi2 etc). It's a mains powered drive and I plug it directly into the USB 2 slot and then into the wall so it doesn't use the MOJO's power. My telly admittedly isn't the best - it's an old Samsung 32" HD Ready thing that usually only goes to 720p (but will detect and utilise 1080p as evidenced by my Ouya) but it has never displayed this issue before. Ouya playback wasn't amazing, but it was way better than I'm experiencing here.
No matter what media player I use, be it Kodi, SPMC, MX Player, VLC or even directly from the gallery, all playback from local files on the drive (mp4, MKV, avi, divx and so on) is extremely choppy. Frames seem to be dropping, jumping and lagging, making video viewing unbearable. At first I thought it was the media player, but no matter what I settings I adjust the video will stutter. I've tried my own recommended settings, and many different types of combinations but nothing stops it. Believe me, I've spent hours at this! I've even tried changing out the HDMI cable for something better but it's made no difference.
So now I'm pretty confident this is happening at system level and cannot be addressed in the player's settings. There must be a setting somewhere that needs to be addressed to enable better video playback. Please please help me, I am going insane. Or could it be the TV and I should buy a proper HD set?
Either way, help me end this madness please!
Too late to get help before you go insane--you're addicted to Androids.
Do you have the same problem streaming from the internet? That would tell us if it's an input or output problem. Also, don't let's overlook the obvious--are you plugging in the HDD into the USB3 port or the USB2? Have you tried copying a file to a good fast microSD card and playing it from there? (the Samsung EVOs recently dropped in price dramatically). And it might be worth trying out CM12.1 again too. Maybe even trying a different USB cable to the HDD. But you didn't have this problem before you reinstalled RemixOS, did you? I'm rambling but I want to get as many ideas out before my short-term memory loss kicks in. But I would think the MOJO has plenty of horsepower on any Lollipop ROM to play videos at 1080p. Resource hog running in the background? Did you try a task killer?

Thanks for your detailed reply!
1. Playing video via the YouTube app looks fine.
2. The HDD is plugged in via USB2. The CTRLR dongle is in the USB3 slot.
3. Haven't tried playing a file via SD Card. I have a good Sandisk one somewhere and will give it a go. Good idea.
4. Will certainly try a newer USB cable as I do like to eliminate the obvious and easy solutions first where possible. But no, I did not have this issue with the Rpi or the Ouya.
5. I will try a task killer but like you I don't think this is the issue. Going into Remix settings there doesn't seem to be anything reported as taking up a lot of memory.
Two things I have tried since posting. First was playing the same files with OSMC on Rpi2, and second was changing the HQ scaling on the MOJO in SPMC. On OSMC I notice I do seem to have a duff file, one in particular that first got me worried, but I was still getting some judder with other files. As for HQ scaling, my Google Fu reveals the usual recommended setting is 20% rather than the default 0%. But after playing with it, I've put it right up to 70% and this seriously seems to have helped. I'll keep playing and see how it works across different files. It's such a shame that Android doesn't switch the display mode like Linux does on demand.
I don't think it's the fault of Remix any more tbh. I'm pretty sure I can get this right. But there's a lot of trial and error and I have a lot of varying content to cater for. However if all else fails I will indeed give CM 12.1 another go. Unless there's going to be a CM 13 soon....
Again, thanks for your help.
I think first I'd try swapping the dongle and the HDD, see if the USB3 port does it. Next another USB cable, is the HDD USB3 compliant? If so make sure the cable is also.
I wouldn't count on any more development happening for the MOJO. Aside from Mad Catz, there has been only one developer working on it, and I haven't seen any posts from him lately. CM makes it as easy as humanly possible to port their ROM to any given machine, and they publish a guide for it, so next time I have a few months off I might try to aquire that skill. But don't hold your breath.
The HDD is USB2 only. I'm going to try a shorter cable I think, if I can find one in my cupboard, but I'm hoping I've fixed it in the settings for now. I hope so anyway as I really like Remix OS and don't want to change.
No, I don't have any expectation of any further development really. I just remember UJD talking about the possibility of CM13 but that was some time ago. To be honest though if there was never another made for the MOJO, it wouldn't upset me very much. We already have three or four brilliant options on 5.1.1 that are a huge step up from the stock rom. I consider myself very spoilt for choice.

Ya, I feel exactly the same way. FWIW I also feel that way about my Asus TFs; I now have marshmallow ROMs for TF300 and TF700, and the performance from 3 and 4-yr-old tablets is amazing.

[GUIDE] Using OnePlus 8 on LineageOS 18.1 as gaming console (HDMI out etc)

Hi guys, I just got a OnePlus 8 and loaded LineageOS 18.1 onto it and wanted to use it to play games on my 4K TV.
The following is a list of the problems and solutions I encountered to get there.
First, I used a USB-C to HDMI adapter on my 4K TV.
I connect my DualShock 4 to it via bluetooth for a console experience.
a) Problem 1 - Full screen output is shifted to the right slightly (black bar on left side)
Solution 1 - I rooted and used this Magisk module here with the OnePlus 8 preset. It requires enabling in Developer settings (Cutouts) after installation.
https://forum.xda-developers.com/t/module-n3o-no-nonsense-notch-overlay.4226413/
b) Problem 2 - Aspect was weird (black bars on top and bottom)
Solution 2 - SecondScreen with the resolution set to 1080p fixed this. Full screen on TV.
c) Problem 3 - Despite setting SecondScreen to 1080p, phone was outputting to my 4K TV at 4K30Hz (and presumably just upscaling). Horrible input lag and frame rates. I could find NO SETTING to change this anywhere. ADB commands such as adb shell wm size etc had no effect and I think are just what SecondScreen uses behind the scenes as they produced a similar effect. But when I connected it to my 1080p monitor there were no issues, things were smooth and responsive so....
Solution 3 - I bought something like one of these: an EDID emulator for HDMI and it is working like a charm. Fools the phone into thinking the TV's max res is 1080p and so the phone outputs at that. Now buttery smooth frame rates.

d) Problem 4 - Brightness on phone weirdly tied to brightness on TV. I had to run it at full backlight to get full brightness on TV
Solution 4 - Disabling the display anti-flicker setting seemed to unlink the brightness on the phone and TV. Now I can play at normal brightness on TV with zero on phone (set by SecondScreen)
e) Problem 5 - Using a phone as a video game console uses battery.
Solution 5 - Got a new USB-C adapter that allows charging. Not this, but something like this. Confirmed can charge and have video out to my TV at the same time.

And there you go. So far this seems totally viable and cool, and I am a fussy, hard-to-please kind of person.
I am looking forward to using this to keep playing some RPGs I would like to get through, with a console experience at home but still able to pick up and continue a bit when out.
Hope this helps someone! Spent hours googling and trying to figure this stuff out.
It's **** like this that got me into modding droids in the first place. You are a legend and a gangster. Keep on doing whatever. XD
This is an excellent guide and gives me more confidence to install the mod and mess with it. Thanks
Useful info like this will hopefully increase the likelihood that the community will use roms to implement the desktop experience. Maru was one example I saw a redditor post but it's in early development.
Also check out Taskbar which is an excellent app for DTE on non-rooted phones
