What if there is no display signal on my monitor?

1) Check if the green indicator light is on. If it is not, re-plug the two-ended power cable or change a power receptacle.

2) If the green light is on, re-plug the power cable and display cable.

3) If you are not using the HDMI cable that came with your Remix Mini, change it to the HDMI cable if possible.

4) Monitors that only support DVI ports may experience a display issue. Our engineers are currently looking into Remix Mini’s compatibility of DVI.

5) Some monitors do not support our default resolution of 1280x720@50hz, try connecting to another monitor and set the resolution to 1920x1080@50hz or 60hz before connecting to your desired monitor.

    Someone from support keeps giving me this link as a workaround for the display colors flipping from normal to green/purple and back every few minutes. There is no workaround for this issue here. That issue has to do with the color space the HDMI driver uses for displaying video content. I've seen this before with my Open Hour Chameleon Android based media player and there it was only resolved after the developers gave us the option to select the color space to use. By default they were using YUV444 which isn't the preferred color space of my TV (which seems to use RGB). So when the color space information in the HDMI data stream is missed somehow during display (temporary hickup or timing mismatch) the TV picks the color space it prefers (in my case RGB) and displays the YUV444 stream as a RGB stream. Since the Y component (Luminance or brightness information) is mapped to Red and U and V (which normally encode the color components) are mapped to Green and Blue the picture starts looking like its rendered in Green and Purple shades.
    The only solution for this issue (as de OHC devs discovered) is to give us the options to set the color space used by the HDMI driver. There are no other solutions for this problem for TV's/Displays that use RGB color space by default.

    This issue was also a major problem for UPC's Horizon media boxes and TV's from all major manufacturers (Sony, Philips, Samsung etc) were hit by this until they did the same as the OHC devs.

    Dear JIDE-Support-Team,

    as you proberbly can imagine, many of Remix-Mini-Users out here are waiting for a solution for the DVI-issue.
    So am I, as "The world’s first true Android PC" should be usable as a PC with a PC-Monitor and not only with the big TV-screen. There are already several settop-boxes for that environment.

    You said that your engineers are currently looking into Remix Mini’s compatibility of DVI, but nothing about progress on this.
    Is there a time table or something? Actually I cannot use the Mini like this - with a HDMI-DSUB-Adapter the image is not very "enjoyable".

    Hoping for a solution for this issue,
    Greets.

    Regarding above post - thanks so much. No update will help those of us who cannot boot at all to any display signal. We NEED replacement units ASAP.

    Hi - let me amend my above comment written at a time of intense frustration. I was able late yesterday to get a display signal by using the Mini on my Sony 60 inch flat screen at 720p. So that is some, but far from complete "relief". I still am wondering if and how this unit will ever be able to connect to a regular LCD computer monitor (Samsung 204BW) using an HDMI to DVI cable (my original plan). Do you think this will be resolved by a software update? That is, can the video circuitry in the unit ever do this? Thanks again.

    I am not having this issue, BUT want to ask it since I haven't seen it brought up here. WHAT IF someone wanted to use their Remix mini on a TV that is mounted on a wall. A TV that wouldn't allow the use of the 12" HDMI cable that was provided in the unit? What are they suppose to do?

    David Sommers

    Benjamin - I'm not sure but maybe someone else can help as to whether a longer HDMI cable is okay? I did get my TV to work as stated above but with a longer HDMI cable (6 feet) to my HDMI LCD 1080p Viewsonic monitor no display signal - it did not occur to me that cable length is this scenario could be an issue??

    Longer HDMI cables should not be a problem. Though the HDMI standard doesn't specify maximum cable lenghts it should be fairly simple to make standards conforming cables up to 5 meters long (or about 16 to 17 feet long) . I've personally used HDMI cables up to 2.5 meters. A friend of mine used a 10 meter cable in combination with his beamer, but that was a special and relatively expensive cable.

    I personally would have left the 20 cm HDMI cable that Jide included out of the box, it's the most pointless cable imaginable. When I use it the Remix is dangling next to my 46 inch TV because it is so short. They should have put in a cable of at least 1 meter (3+ foot) in order to make it useful.

    It works correctly with hdmi->vga (dsub) adaptor. I paid about 10 $ for it.

    Have a nice Christmas!

    Will anyone of Jide suggest what time will it take for them to solve the HDMI to DVI issue?

    Ultimately, it is not quite fair to test your piece of technology on consumers without letting them know that it is not ready, i.e. no support for DVI, no support for changing keyboard layout, etc.

    I have same problem as PieterJan Kuyten. I'm using my remix mini with a Sony Bravia TV that turns normal colors into purple/green colors randomically. I hope devs will implement full RGB color space profile in display settings the next update

    I managed to connect it to my monitor using a HDMI to VGA converter I bought on Amazon.it (brand is "Ugreen"). All the other adaptors and cables I bought to connect to DVI didn't work at all. I obviously consider this a temporary solution and I hope the resolution control will be unlocked soon: I'm pretty sure the HDMI to DVI issue is caused by the fixed resolutions.

    @Gino Pellegrino : the DVI issue is caused by the fixed resolutions. A Dell U2713HM (2560x1440) will display every of the resolutions offered by the Remix Mini, while a Dell FP2001 (1600x1200) won't display any... My hope is that the hardware of the Mini is capable of producing the right signals and it is simply a problem of updating the display driver.

    I too are very disappointed that I cannot use a simple HDMI to DVI interface cable with my two Mini's. My temporary workaround was to use a HDMI to VGA convert I bought on Amazon (Tendak Gold-Plated Active HD 1080P HDMI to VGA Converter Adapter Dongle with 3.5mm Audio for Laptop PC Projector). It worked fine after I adjusted the Mini's output to 1280 x720 60Hz. Jide, please continue you focus on a solution that includes the simple HDMI to DVI cable. Thanks,

    The issue over the HDMI to DVI monitors was first highlighted shortly after the mini was shipped. It is now mid January and there have been no updates on when we can expect a resolution to this problem. Just silence. Has any work been done to try and resolve it? If so, why haven't we been told about it? If not, why? For a company that prides itself on being "customer focused" , this is an appalling public relations failure.

    Dev team seems very poor, I hope to be wrong and to see short-term results. I believe in Remix mini and I hope Jide don't leave it ad they did with the tab...

    This is very disappointing indeed. If this cannot be solved by software engineering - which i see as distinctly possible - that is, the chip in the Mini cannot handle DVI/VGA - alternate resolutions, etc - you really owe those of us who care about this issue a replacement. Please be careful how you handle this - the internet/reputation engines can both make and/or destroy new businesses. Thanks so much.

    I tried to set up my Remix Mini with a LG IPS231P-BN (1920x1080, VGA+DVI) monitor and an Equip HDMI to DVI-D Dual Link Adapter (http://www.equip-info.net/Adapter/118909/p-201.htm), but I only got a black screen after starting the device. Later I connected it to a LG 42LA691S smart TV with success. After updating the Mini and trying the workaround mentioned earlier (http://support.jide.com/hc/en-us/articles/213537078-I-m-having-issues-with-connecting-my-Remix-Mini-to-a-screen-monitor-What-can-I-do-) I got the same black screen on my LG monitor. Please fix this issue, I don't want to buy an other display just for using the Mini.

    Hey everyone, it's been a while since we've replied to this thread. We hear you guys. While it may seem like all our attention is focused on Remix OS for PC, a majority of our engineers are actually still dedicated to Mini updates. While I can't say exactly when the screen issues will be resolved, our engineers are actively working on this with our chipset maker - Allwinner. The good news is the latest test version of the Mini ROM has now in theory passed Google's CTS requirements. We're currently validating the results of the test to make sure that everything is sound, but that release is schedule for the near future. Thanks!

    @Jeff Zhao First of all - thanks for the update.

     Let me summarize what I read out of it:

     1) neither your engineers nor Allwinner can say what additional (non widescreen) LCD resolutions the chipset can support.

    2) regarding the current resolutions you try to solve those HDMI and HDMI-to-DVI issues.

    3) none of these fixes are included within the next ROM.

     This is a bit frustrating as (1) is the most important for me (and I think many others too). It comes down to having to buy additional monitors just to use the Mini or not...

    @Jeff Zhao, thank you for this update. Regarding the resolution and hdmi2dvi issues, maybe you should consider allowing us to root the mini (I think I understand Jide would consider that a licit reason to void warranty and cut future updates, at the moment). I would love to try and see if forcing different resolutions is possible or not...
  • Avatar
    michael.keller
    @Gino Pellegrino I don't think that rooting the Mini would give us the ability to add resolutions. If it would be that easy like putting in some lines into a "resolutions file" - Jide would have done that already... . My guess is that there is some "real work" to be done and without having the support documents of the Chipset it is near impossible to add anything....
  • Avatar

    @michael.keller you are probably right (I'm sure you are, honestly), but trying would do no harm anyway. I've been playing with a little app (NOMone Resolution Changer) that I've been using on tens of different Android machines to change res without having to root, and it always worked flawlessy. On the Mini it apparently works as fine, no crashes, no black screens, only thing resolution simply stays the same without any clues about what didn't work. This makes me think that either (1) the resolution is intentionally nailed to the 4 options for some reason I can't guess or (2) chipset has been designed to work that way, maybe to simplify its design and production in order to cut the final price. If (2) is correct, I am afraid we are not given any fix because no fix can be possibly given.

    @Gino Pellegrino Just googled the app and I think that it "just" changes some variables regarding the screen resolution and pixel density reported from Android to the Apps. The physical aspects of the used resolution remain untouched. You may be right with (2) BUT THEN it should be easy for Allwinner to communicate that to Jide which can tell us... . It would be a kind of letdown but at least I have a foundation to make decisions.

    @michael.keller you are right about the app, but what makes me curious is why it doesn't fool the mini...
