The transformer is doing some clipping overscan in each TV or monitor that I try. It removes nearly 40 pixels in each side. For example menus doesn't look complete in programs, videos are cut etc. Is possible to avoid this?
Set your monitor to 1:1 pixel mapping.
Each monitor have different options for ajusting HDMI screen but in the 3 monitors that I have tried none make disappear the problem: a IIyama computer monitor with HDMI imput, a Pioneer plasma screen and a Sony LCD tv.
I suppose that there is nothing in the transformer to modify these settings.
Not that I have found, and that's very odd, since my HDMI works fine on 5 different monitors/televisions.
Have you tried a factory reset? Or flashing a custom ROM?
yes, I have reset to factory etc
I thought that this was a normal issue
I had to set -1 for overscan, it is normal. If your TV doesn't let you set overscan/underscan good luck.

well, you don't say what happens, but here's what I did:
10 foot micro to normal hdmi cable.
Plugged it into the tablet. Plugged the other into the TV. Turned on the TV.
Works great! Btw, the bottom bar with the buttons and clock do not show on the TV (by design.)
I have 2 and both have issues if your holding the tablet with HDMI plugged in. It seems the port is a bit weak and so laying it down is the best way for them to work.
Me too
I can't get anything to show on my Panasonic 720P Plasma. Would the native resolution of the TV be a factor?
I've tried 3 different cables, tried jiggling the connections...the micro HDMI does seem to wiggle a little bit...almost like it's a little loose
I bought a cheap cable off ebay, plugged it in, selected HDMI input on the TV and it works perfectly.
Mine is a rooted stock 3.1 but it also worked prior to the 3.1 upgrade.
I thought the same first time I tried.
Turned out to be cable. Got another and that was fine. Worked first time.
Got a replacement for the original and managed to break that on the first go.
To paraphrase Archimedes, Give me a HDMI port small enough and I will break it.
It only takes a litttttle bit of vertical jiggling and it snaps the end off.

Same here, used micro to hdmi cable included in my Motorola Droid X (in Mexico it's called Motoroi X).
Works nice, it mirrors all but bottom bar and not only by desing but also screen is 800px tall and 720p well... 720px tall, so bar is hidden wich is perfect BUT:
Youtube app ROCKS in HDMI, you see the video in your big screen but you see complete layout in your tab, comments, relared videos, video playing in mini mode etc. but I found that sometimes doesn't work (very rare), also flash sometimes works nice and sometimes it kicks you in the balls.
I got an RK8 box and runs great with my 4k TV. Exception being HDMI. When I turn on the RK8, it will not display on my TV. I have to unplug the HDMI from the box and plug it back in and than it will work. Is there a setting that I'm missing?
It's plugged into my HDMI port on the LG for 2.0. The TV also recognizes it as an HDMI 2.0 devices and switches the tv to 10bit colour on that port. Only issue is unplugging and plugging back in the HDMI cable to it to show.
Hi Kevin. Have had the RK8 for a couple of months now, and after the first couple of weeks using it on my Samsung UE65JU6070, I can no longer switch it on with my remote (switching off works fine), thus I have gotten used to unplug/replug the power cord. Maybe it's the same issue you're experiencing? I'll check tonight if unplugging/replugging the HDMI cable does the same trick for me as the power cord.
Can I ask, what is your experience in playing 4K youtube video's? It seems mine is very reluctant to do so (doesn't work on the youtube app, and only sporadically using a webbrowser).
Otherwise I agree with you .... it is a great box which seems to run very stable without any overheating issues etc. ..... and having upgraded KODI to 15.2 means I no longer have any stability issues there either (NB: if you do this update, you need to uninstall the pre-installed KODI 14 first .... so remember to save your settings etc.).
Just a last comment. At 70 USD this seems to me to be great value ..... I'm surprised it's so difficult to find other people on the Internet who have experience with this box ....
Best regards Mogens

I have no remote/power issues. Just issue with it showing on my tv. It powers up and won't display. TV see's that HDMI3 has power but does not show unless I unplug/plug the HDMI cord in the box.
I don't use youtube on this box. Just Kodi.

Hi again Kevin. Since my last post, it has happend 3 - 4 times that I've experienced your issue of "black screen", but for me it has come out of the blue. Picture comes back when unplugging and replugging the HDMI cable just as you say. I was wondering if you have gotten any closer to find a solution?
Pls be aware that I tried to update to Kodi Jarvis (16.0) release, but went back to 15.2 due to an issue with menu text being "corrupted", which required each time starting Kodi to go and change the font. Allegedly it's an issue related to HDMI as well, so I'm wondering if there is some "glitch" in the box' HDMI implementation (HW or FW).
I'm sure you have tried already, but if not, have you tried to move the HDMI cable to another input on the TV? Do you have some configuration possibilities with the HDMI inputs on the TV ... if yes, maybe play around with those.
Small quirks ... but I have to say that for USD 60, this is still an amazing box even if I still cannot power it on with any remote (but power off works fine with all remotes).

I haven't had time to work with it to be honest. I think its a poor HDMI 2.0 design on the box. I still have the issue and just yesterday, my Kodi updated to 16 and I get the same issue as you with the block lettering which I haven't tried to fix as yet. Thanks for sharing changing of the font.
Reason I suspect its the unit and not tv, is because sometimes when it does not display on my tv. The tv gives a pop up indicating "The device connected does not support 10 bit deep colour". Then I unplug and plug and it goes away.
Hopefully I can get sometime to fiddle with it more and see how it can be resolved.
Have you tried to see if there is a software update? The update option on my box does not even work. I wonder if we both got knock offs or just duds.

Hi Kevin,
The box is made by Acemax, and there is no FW update since the original (believe the one it's shipped with is dated 30. sep 2015 ...but that's from memory as I'm at work). I don't think it's a knock off, but I do think it's a "standard" board which is basically put into a plastic cabinet, where the only difference to identical spec products (like the Xidoo X6 Pro) is the location of the USB ports. It seems it uses exactly the same components as that one and others similar to it ... however, Acemax do seem to have FW updates for other products they've made on their homepage, so ... who knows. If somebody is brave and skillful enough, such person may even try at install a FW from f.ex. the Xidoo box ... but I'm afraid that's not me (not due to lack of bravery, but ... skill!!). With that being said, I believe my issue with having to unplug/replug the power cord once per day is something I can live with easily (and it has worked, so it may be a question of resetting the box, which I frankly am to lazy to do!!), so .... I guess looking at such small quirks and comparing them to the overall usability of the box, then the trade-off is not too bad.
A quick view on a couple of threads for similar boxes (f.ex. the Xidoo) would seem to indicate that some of their users are having issues that makes ours "luxury problems" in comparison.
Anyway, I'll keep you updated if I stumble over something useful .... and would appreciate if you do the same.
P.S. A "clever" streaming guy has told me that the best Kodi version in terms of stability for live TV streaming still is Helix .... although I'm quite happy with Isenguard (got too tired of the font changing thing on Jarvis, so I re-installed Isenguard). I'm more or less only using mine for streaming HD channels (mostly UK Sky / BT sports) for EPL, and it works fantastic.
I found a weird solution for the unplug issue! When I turn on the box and my tv is on the hdmi port. I turn the tv off and turn it back on and the box displays. Tried this a few times and it worked.

Not sure if you saw my last note about the power. I've also figured out more about this box. It has a rockchip which is one of the worst to use. Kodi does not support that chip fully, hence the weird text when launched. We have to stick with the preload or, I've read some place to download the "X86" apk from the kodi site. Also, I tested my box on a regular 1080p tv with hdmi 1.4. And the issues of it not displaying right away, are eliminated which lead me to believe the hdmi 2.0 in this box is poorly designed.
I'm probably going to use this box in my room and get a box with an Amlogic chip for 4k as those are the better boxes to have and more support is offered.

Hi Kevin,
I just now saw your other post about the power .... I tried that myself, but to no avail.
I'm not sure you're right about the Rockchip being one of the worst technically, but in terms of support (official and un-official) you're right.
However, since I use my box for watching IP TV, I can live with using Kodi 15.2. I've tried the Kodi 17 dev version, and it has the same issue with garbled text as Kodi 16.
The Kodi x86.apk cannot be installed on our box .... I tried yesterday, but I guess it is for an Intel based android solution.
In terms of HDMI 2.0 implementation, I wouldn't be surprised if it's not perfectly implemented .... not sure if HDCP 2.2 also plays a role.
Anyway, at the end of the day you get what you pay for .... and since I paid USD 65 for my box, I have to say I feel I got a lot of value for money, despite it's few quirks .... and as a friend of mine always says; what kind of life would it be without complaints

Hi again Kevin,
The family being out for Saturday shopping, I spent a little time with my afternoon coffee on the computer.
You are right, that KODI do not support the RK3368 SoC, as the manufacturer does not comply with Android standards, which necessitates that standard KODI is "hacked" to work perfectly with this chip .... something the KODI development community naturally does not want to do.
However, it seems the manufacturer Zidoo whose Z6 box is based on the same SoC, has showed some good customer service, and actually created a ZDMC app, which is basically KODI 16 with a few modifications for RK3368.
I downloaded their firmware for the Z6 box, and extracted the ZDMC apk from there and installed it on my RK8 box ..... and albeit I've only tested it shortly, it works beautifully with no issues so far. Apart from not having garbled menu text, it also seems like it's actually able to make 4K output (the standard KODI irrespective of versions only seemed to be able to show FHD, but would in turn show a refresh rate of twice the actual .... too techincal for me!).
Long story short, if you want to test it out, I've uploaded the above apk to Mega with the download link below.
https://mega.nz/#!TR1SEByC
Encryption key needed: !kN-15aGvZljVdKEus9LT7NxCYjqnthR8bbaYD_YfhiQ
Let me know if it works for you and/or if you find anything. Also let me know if the download link doesn't work.
Enjoy your weekend!
Best regards Mogens

Hi again Kevin,
Just a last comment this time around. I've now used the above mentioned RK3368 "modified" version of Kodi 16, and I have to say it is extremely stable and works better on the RK8 than Kodi 15.2.
If you have a chance, try it out. Given the very, very limited 4K material out there, I hope this box should be able to carry me through the next couple of years until availability of material as well as new compression methods become available.

I am looking at doing a project where you take the LCD from an Android tablet (I have an old SCH-I905); and add an HDMI input to it so it can be used as a monitor. I have no experience with how I would even get started on this; besides the 3+ days of Googling that resulted in nothing. I would very much appreciate if someone from the community had something to offer! From some research, what I could see that would maybe do the trick is using some sort of LCD controller board.
Thank you.
do yo know how to operate LCD controller of your SCH-I905? i think if you just want to use your device as an external monitor that you can use 3rd software to do it.
I am interested to know if you have found a way
I'm interested on projects like this. I want to put a female hdmi to lcd or the board or something like that, to view on tv, ie: watch videos without using screen mirroring (for older lcd tv's), playing games in real time (without cuts), youtube, and many more things. If anyone knows about it, please let me know.
Best regards
Im also looking for the same thing. I actually wanna find a way to make my old phone into a notebook. My old notebook motherboard has broke, so i wanna try to transform my phone into the notebook itself using the hardware that is left. I'm pretty sure i wont make it, but ita worth the shot.
Ok, so i have my Galaxy S5 tmobile that ive been playing with recently. awhile ago i tried to replace the rear facing camera, and the loudspeaker. unfortunatly when removing the screen, the digitizer was damaged. oled was working great. i would just use a bt mouse to navigate. well last night i pulled the phone apart to compare the amoled connection to that of a S7. just to see if i could throw the S5 screen onto my broken S7 to attempt to setup screen mirroring to my tv and be able to use it with a keyboard and mouse for general streaming.
I left the screws out of the midframe assembly of the S5 and it fell off the table after being reasembled. (love when the pets get into my workshop)
anyway, it was just enough to crack the very corner of the OLED and now there is no functionality to the screen.
ive been thinking about trying something that i just havent seen before, and cant find any information on at all.
There has got to be a way to take the ribbon cable from the S5 screen with the connector and splice/solder into some kind of digital video output. also the audio to the loudspeaker adjusted to low-line and connected alongside the digital video to make a single digital A/V output.
Basically i want to have my BT keyboard and mouse and be able to have it outputting video to either a Moniter, tv, wireless adapter of some sort. i would leave the OS pretty much the same minus alot of needless software at that point, and be able to turn essentially any tv with HDMI or digital video in, into an android smart tv..
i have arduino uno kits and Abillion cables of all sorts.
if anyone has any insght to the format of video coming from the OLED connector, or a pinout , any information that would help me get the ball rolling on this. i would be extremely grateful.

They are nice and all. But that would mean I would have to spend money on something to make it work... Also mhl adapters take their own power supply at 5.0v, which means it would have to be plugged in somewhere during its use. Which I had planned on just using a couple 8000 mAh lithium batteries wired in parallel to power the phone at 3.7v. Getting me somewhere between 6 to 8 days of heavy usage before a recharge. And would make it much more portable.. Maybe even construct a small enclosure with a fan out of one of my CCTV cameras. Even if I had to convert the video and audio signals using a microprocessor, I wouldn't have to spend a dime doing the entire project if it works the way Im imagining it too. One of my main objectives with this project is to use parts from old equipment that I already have.
This is more about doing something creative and new with old Galaxy phones that have no other practical use.
Yes I could order an android box off amazon for less than 20$ and do what everyone else did to stream...
Yes I could order an mhl cable and set it up that way....
Yes I could put a new display assembly on it and use it for dev....
But if everyone thought like that, android wouldn't have existed in the first place.
