Need help outputting to an SD analog TV. - Shield Q&A

Hey guys,
I use my Shield for interactive ESL classes in a number of schools I teach in, most of the time it's okay because these classes have newer TVs with an HDMI in. Occasionally I have to give the digital lessons a pass however when the classroom has an old CRT-tube 4:3 TV.
Now, I found an HDMI-to-RCA converter I could buy to fix this problem, but I suspect if I were to use it the aspect ratio might get all screwed up.
I'm assuming when you enter Console Mode, the Shield defaults to outputting in 1080p? Does anybody have any suggestions to getting it to output in 640x480 natively? Or could somebody suggest a converter box that adds rowboxes to maintain aspect ratio?
Any help would be appreciated!

Is there a way to change/resize hdmi output resolution ? doesn't fit my tv

As stated in the title, unfortunately my TV won't let me resize the image while using hdmi mode (don't know why...) and I can't see part of the image.
Is there a fix ? (even rooting)
thanks
I put mine in exact scan mode and it fit the screen correct, if you have that or a PC or gaming mode where it goes 1:1 with the pixels it might look better
Still couldn't fix this issue with my television screen, im attaching an image.
thanks
I have this issue as well. Hate it.. Anyone have a fix?
since I'm rooted I'd flash anything to address this boring issue
My TV has the same problem with different sources. Usually computers. It is a TV problem I think. However, my TV works much better with a smaller input size. It leaves about an inch around the outer edge. Hardly noticable though.
Maybe there could be an app for that. Like SetCPU does with OC's.
I had the same problem since the TV was looking for 1280x720 and the transformer is giving it 1280x800 instead. I was able to fix it using the built in scaling feature on my TV. Its an older Sony 720P DLP TV, so I'm sure most of the newer TVs have a similar scaling feature.

can't understand why but while in HDMI input it won't let resize the image, no problem with AV (like with my xbox)
I wrote about the same issues in another forum (asus transformer forum) and there are other guys experiencing the same issue.
thanks for the replies
I have this to not quite as bad but i cant see the bottom of the screen or a little bit on the edges but the top lines up sweet
I have tried everything hope somebody makes an app or fix for this maybe revolver parts screen resizing !!!!!!
Some tvs suffer from overscan and there is no fix. That being said, www.avsforum.com might be a better place to get more info on tour specific tv

Mx video viewer allows me to pinch to zoom in or out that is what I use cause it was driving me nuts as well.

Don't take this the wrong way but.... could be a cheap tv. My parents have an insignia and there is no 1:1 screen setting even on pc or gaming mode. It always cuts off the over scan space(no overscan).

I had the same overscan problem initially with my toshiba LCD TV, ie. the sides of the transformer desktop were clipped off but i fixed it via the Toshiba's screen adjust settings whereby you can select aspect-ratios such as "16:9", "4:3", "cinema" etc.
The setting that worked for me was "Exact scan". I believe it is called "Native" mode on some other brands of TV.
That's where to look.

Exact scan
Just scan
Native
Pc mode
Usually what it's called. Its just over scanning or a 1:1 pixel matching. But not every tv has this option.

Webtop to Netbook (NOT Lapdock)

OBJECTIVE:
Webtop from Atrix 2, via standard HDMI, to standard laptop HDMI input.
PROBLEM:
Most HDMI ports on laptops are output only.
SUGGESTED SOLUTION:
HDMI to USB or HDMI to IP converters. not sure this even exists
Update to this post:
The original product link was in error (pointed out by "IceFragmatic"). As suggested by IceFragmatic, most USB video INPUT for laptops/netbooks, are intended as capture devices, although I am not sure what he means by "due to DCHP", regarding HDMI being a very rare capture source.
Has anyone attempted this?
The item you link to is USB to HDMI...again outout only.
You would need to use a capture device (which for HDMI is very rare due to DCHP)
Why not just buy a cheap screen with DVI and/or HDMI input?
I know that for the last few years, that there have been a small handful of expensive giant laptop PC's that provide for HDMI INPUT (yes, input), but there are as yet no netbooks or UMPC's that have a means to provide this .... would you agree with that statement?
(this is interesting from a hardware perspective, not necessarily from a business strategy perspective)
You're better off just using a VNC server program on the phone and a VNC client on the netbook while connected to a solid wifi. That will allow you to control the linux environment running on your phone from your laptop and doesn't require expensive video capture hardware. One does not simply use one's netbook as a monitor.
Sorry, should have referred to HDCP (not DCHP).
HDCP is a copy protection protocol used to stop digital copying of comercial DVDs and some TV streams.
The movie studios and owners of the HDMI licences do not want HDMI recorders without some form of protection to stop copying of DVDs. If this copy protection did not exist you could make perfect copies of DVDs and BluRay. Therefore HDCP has be introduced. This makes HDMI input/recorders useless for anything but home-made movies (and therefore not a big seller).
Your homework is to read the following....

Possible to change MHL-HDMI out resolution?

I scoured the internet and these forums for an answer to this but found nothing. Does anyone know if this is possible? I know the max res is [email protected] and that is what my tv displays. I would like to set it to [email protected] (best for movies) or possibly even [email protected] (for gaming).
All I can think of is getting an adapter that tricks HDMI into thinking your TV isnt capable of doing certain resolutions, but I would rather not have to go that route.
Thanks.
if your tv supports it, force it into another resolution and see what the phone does with it. on my tv i can set the resolutions and refresh rates on the different inputs.
unfortunately my tv does not support that, who makes your tv? i have a 2009ish samsung lcd, i am pretty sure i know that tv inside and out but its possible the functionality is hidden away somewhere.

Android PC stick doesn't show the full 1080p picture. What do?

I've recently bought an HDMI Android PC Stick and I actually love it. However, I bought it because I want to watch 1080p videos in various formats with subtitles on my HDTV . The problem is, after I plug it in it starts and works perfectly but doesn't fill the whole screen. All the settings are ok. Is there some system file that I can edit to make the stick produce Full HD image?

LG 360 VR PC adapter

I just thought I should share this, since the VR Headset has extremely limited functionality through the phone.
There is a dongle available from a company in South Korea that enables PC use (for movies and Youtube) specifically for the 360 VR. It basically converts HDMI output from your graphics card to USB-C and also has a micro-USB secondary connection for controls.
The name of the tool is Vagle VRD-1000 VR Data Transformer. I was able to get one from the US Amazon this week and waiting for it to arrive and test.
The price was not prohibitive compared to HDMI to USB-C capture boxes that run for a few hundred bucks and it seems tailor made for the LG 360 VR.
Cheers
I'm curious to know how this works out for you. Considering you can grab an LG360 VR google set for under $100, would be a fun addition to play with.
And it works

I've received the adapter this week. It works as advertised for playing individual VR video files and Youtube VR streams. I had to download the VR Player from the manufacturer's website and it appears like a modified version of CodePlex VR Player. It includes a device preset for the LG headset. It also installed the K-lite codec pack and VLC automatically.
Head tracking works, video was a bit jittery as I could only test it on my laptop under W10 with an Intel IGP. The manual specifies Intel Graphics are not recommended. My desktop is sitting waiting for memory modules and I will test again once fixed.
One thing to note - as I connected the glasses through the adapter Windows set them up as a second monitor at their native resolution however I couldn't see anything. The glasses only fired up as I've opened the VR Player. However, after closing the player, the glasses still showed the desktop, but it was rotated by 90 degrees. I will try to rotate the desktop on my PC and see if I can have the picture laid out properly. If it works, it might allow me to play my flight sim on the headset.
Long story short, if you want to watch VR videos on the computer, the dongle will work. I've got the LG 360 VR for $60 off ebay and ended up spending more for the dongle ($90). All together it came down to less than a brand new LG 360 VR bought from LG.
whereto download this vr player?
hi Rothas, I tried to plug lv 360 directly into my NUC which has usb-c (thunderbolt 3, compatible with displayport over usb c), it recognizes it as a display 1440*960. but like you said below, nothing is shown on the goggle. want to try this vr player - you said you had to download from manufacturer's website? can't find the website even , can you help?
thanks

VR Player
Good to see you found it, could you let us know if it works on the NUC without the dongle?
Also, make sure you select the LG device in the player, that is what brings the picture up on my headset. Thanks.
It worked !!!
wow, good news everyone, this really rocks: get LG 360 plug in to a displayport over usb c compatible computer (NUC 7th gen for example).
and fires up this vr player - so far the image are 90 degree turned - I am so excited so need to share the news first. will tweak more and let you guys know.

everything works inside vr player once the tracker is set to LG ER1 - I guess it tells VR player to align the orientation from the goggle.
can't seems to get it to work directly - it shows the screen but are 90 degree turned, one clock wise and the other eye counter clockwise, so you can't even change alignment in display setting to fix both eyes
overall I am very happy, just saved $100 on this Vagle if your computer is able to output displayport over USB C directly - it works exactly as the adapter does.
thanks Rothas for this great finding, I wouldn't even think it is possible if I did not read your post.

Great
Oh, I forgot to mention to load up the .json preset included with the player, it does something to the viewing plane.
I still haven't tested rotating the display in W10 due to lack of time, I'll post something once I'm done.
I wish I could've saved the $100 but my desktop doesn't have native USB-C :laugh:
Installed the player and it sort of works. I get the 90" rotated display in the player. Unfortunately my windows doesn't see the glasses driver.Any ideas?
I was able to get my hands on a R100 VR headset for a real bargain.
To get it to work in my use case (As FPV glasses for my racing drone) I need help from someone owning the VRD-1000 "transformer":
Could someone owning said converter please open it up and take pictures of both sides of the PCB? I want to gather some information on the SLIMPORT chipset they used so I can hack together my own adapter.
I am not able to purchase the VRD-1000 it here in europe and importing it would cost me over 200 USD which is quite a bummer
Help would be greatly appreciated! Of course Ill share my findings if this leads to something!

You are my hero!
I'll update ASAP with my findings
There was a question about components used in that Data Transformer dongle. It's not a direct answer, but the following press note lists the components used in LG G5 phone and in glasses themselves (google for the following title):
"Analogix and LG Take Mobile VR to the Next Level with LG 360 VR"
The components are:
LG G5: SlimPort ANX7816 transmitter and ANX7418 USB-C switch and controller;
LG 360 VR: SlimPort ANX7737 converter and ANX7402 USB-C controller.
I have a question to alanma75. What happens when you plug LG glasses to your NUC, without starting that VR prlayer? What do you need to do to force the glasses to show anything?
I have access to one Win7 and one Win10 laptops with USB-C interface. When I connect glasses to them, laptops recognize an external display of 1440x960 resolution, I can extend the desktop to that space, I can drag the windows there, but the glasses remain dark. For a moment I thought that simply there is no back-light triggered, but I don't see any activity on those LCD pa panels (yes, I unscrewed the lenses to look directly at LCDs). What needs to be done to kick-start the goggles?
Just picked up one of these headsets for $20, B&H photo has them refurb for that right now. Have had my eyes on these to try and hack and mod a bit.
But reading over the info, it's gonna be a tough one, maybe not really worth it.
The Vagle VRD-1000 is pretty interesting, this PDF has some interesting details about what it does internally:
http://tvlogic.tv/VR/vagle(VRD-1000) Product Profile_v1.0(ENG).pdf
Interesting parts: I see HDMI to Display Port and DDC. DDC appears to be "Display Data Channel" which is an i2c protocol. See here for some info on that and how that fits in to USB - C https://www.mouser.com/applications/usb-type-c-adds-hdmi/
Perhaps DDC is used to instruct the goggles how to display - for instance it's been mentioned of people getting images, but 90 degrees rotation? Perhaps DDC is used to instruct the goggle how to orient the image, etc.
Then also I see mentioned "Coordination info" this is probably motion tracking info I'm guessing. Personally I'm not as interested in this aspect, I'm more interested in just being able to control the displays, maybe get general HDMI input working.
Here is an interesting github project that appears to be using or attempting to use the VRD-1000 along with this headset https://github.com/TrueOpenVR
How about an adapter Type C to USB 3.0, somebody tried, it works?
The code for get orientation data from USB сan be found after decompiled "Vr Player.Trackers.LgeR1360Tracker.dll" (C#, decompiled without problems with using ILSpy). File "Vr Player.Trackers.LgeR1360Tracker.dll is located in the player folder [1][2]
There can do support for SteamVR and other vr programs.
snap3D, it is probably necessary to send the packet over USB to enable it. LG G5 (or Vagle VRD-1000) most likely sends a special package to turn on the displays. Probably it's done so people do not try to connect to the PC. Need to capture the usb packet (from Vagle).
I also have G5 phone (and obviously VR360 glasses light up when LG app is running and glasses proximity sensor is covered; glasses immediately turn off when proximity sensor is uncovered), but unfortunately no access to USB-C analyzers. It would be interesting to see if the glasses connected to PC (via Vagle adapter or directly through USB-C interface) can continue to show the image after initial packet trigger. To test that theory I ordered a "MeeGoPad T09" micro computer (for $130 from "geekbuying" Asian site), which is less than $10 more expensive than the Vagle adapter (and as a bonus I'll have a tiny PC running Win10 OS; you can go even smaller with PC-stick "MeeGoPad T08"; both MeeGoPads have USB-C interface). I'll try to install that proprietary VR player s/w (link provided earlier in this thread) on MeeGoPad and we will see what happens.

I think that "USB Packet" might actually be an i2c packet over a wire that's a part of the USB C spec. The DDC "Display Data Channel" signal I mentioned before. So might be easier to reverse engineer than a USB packet would.
del
So I took my goggles apart just to look around inside. Noticed these test pads on the main PCB, labelled GND, 5V, D-, D+ and B. So that looks like USB to me, but not sure what B is. These might just be some kind of ISP firmware update pads or something though. I might try to solder a USB A cable to them, plug it in to my computer and see what happens. Also here's a picture of the back side of the board just for info. Let me know if anyone wants a picture of something specific.
0TheRain0, yes, I wonder what will happen.
Does my $75 solution work better LG G4 with the Oneplus loop VR?
