HDMI freezes; anyone know the cause of this?

I have read plenty of people who have the same problem. When I plug in the phone to the tv via hdmi the phone freezes and resets. I have not found a solution for this. It seems like it is really hit and miss. Any help?

anyone? please?

I'm not sure if this helps but I had the same issue and switched to another HDMI port on my TV and it worked flawlessly.. I notice that the port i was trying to use shows up on the TV menu as HDMI/DVI for some reason even though it is clearly NOT a DVI port

Your cable is probably bad. Mine started to freeze up after working fine for two weeks. I checked the cable and the cord was coming apart at the top by the full hdmi connector.
Two new monoprice cables I got since have been flawless. The first was an amzer from ebay.

HDMI output

Has anyone used the HDMI option on their A100? I have been trying to get it to work for the last 45 minutes and cant. The tablet recognizes that a HDMI cable is plugged in, but I get no display on my tv. Ive tried connecting directly to my tv and also tried going through my surround sound receiver.
Im using a micro hdmi cable that came with my Motorola Atrix 4G. If anyone has any suggestions I would love to hear them.
Thanks.

I've used an hdmi to micro hdmi cable from monoprice and it worked perfectly. I used a 15 ft cable and the screen was crisp and clear. A little stretch on the sides, but bearable...

I ran into the same problem with my HDMI out. Initially, I got nothing, so I switched to a different cable. After a delay of a couple seconds, I was able to get a signal BUT it would drop if the cable moved even the slightest bit. I played with it for a while, but it was obvious that there was a problem with the physical connection. I returned the tablet to Wally-World for a replacement, and the new one works perfectly.

Thanks for the responses guys. Im going to try a new cable and if that doesn't work I'll go for a replacement.

Power FireTV stick via TV?

Hi,
Got my FireTV stick yesterday,
Seems to power fine via the USB port of my Sony Bravia TV.
Even games play quite fluently.
Sometimes the menus are a bit sluggish compared to the regular FireTV, but I guess this is normal due to the relatively slow CPU.
Was wondering if it somehow could still be underpowered and if I would miss out on performance. Is there any way to tell if it is getting enough power?

Check the specs of your TV to see how many miliamps its USB ports have, as long as its equal or more to the requirements of the fire TV you should be ok... it is possible that it can run at lower amperage, but is not good for the hardware, and you should use a proper power source.

I got mine yesterday as well and ignored the advice to use the supplied power supply.
I just used the 1,0 Ah USB port of my Samsung TV. Seems ok, only a warning at start so far.
Without a separate power unit this little stick is really a hidden addon for the TV

It can be powered via just the usb and the tv?

Yeah works for me too, just powered thru the USB port of my Philips TV.

Work fine for usb power from tv as well.
Some old tv have low power usb port then give unstable performance. But with newer tv then it is fine

Amazon Firestick

Hi, ive registered with this forum to ask for some information on the Amazon Firestick. I am thinking of buying a fully loaded stick from Ebay in the UK. My main question is i have a UMC 40 inch TV with a usb and Hdmi port but its not a smart tv. Will the Firestick work or do i need a smart tv. Any help would be appreciated Thanks

No SmartTV needed, only HDMI is mandatory of course. USB power can (or better should) be done with the USB power supply of the stick, so also USB must not be used from the TV and can be left free for other devices which need to be connected directly to the TV.

= Plug the FireTV Stick into the wall for power, don't plug it into a USB port on your TV for power.

I use my tv's USB port for power with no ill effects. We don't use the USB port for anything else, and it means we don't have to have yet another device plugged into the wall. It does mean that the Fire TV boots up every time the TV turns on, but it boots fast enough that this has not been a distraction.

It might work fine for you and other people, but in general, TV USB ports are not reliable as a power source. That might vary from brand to brand, however, it should be noted that an inconsistent power supply or one that doesn't meet the manufacturer's specifications can be bad for the unit over time.
I tried it with other devices. Its a nice way to eliminate wires but I got random reboots and freezes. Never tried it with stick but some people report it works fine.

In general it might work with regular USB power from a TV USB port but I personally had problems with WIFI. It seemed that the stick did switch down WIFI speed (and probably slows down the CPU) when the power is restricted to a TV USB port but does run on full speed with the external power supply. Also those decoding problems during video streaming which is often reported here may come from insufficient power.
A USB port is specified to deliver 0.5A at 5V so thats only 2.5W power which is guaranteed and it´s only mandatory for devices like TV sets to deliver more power. So it makes sense that Amazon did deliver an external power supply knowing the power consumption of their stick My hint would be to check first with external power supply if the stick is running fine and how is streaming working with speed and quality than it is still possible to try only with the TV USB power and it can be compared if there are no negative perfomance issues. But I bet most people will attach the external power again.

Fire TV stick won't stay on its HDMI port

Sorry for the badly worded title, but I can't figure out how to describe the problem. Here is what's happening:
I have my Fire tv stick on hdmi 1, and my raspberry pi 2 running openelec/kodi on hdmi 2.
When I try to switch to hdmi 1, the screen goes blank for about 3 seconds then switches back to hdmi 2 on its own. If I turn off my rpi2 (by unplugging its power) and then try to switch to hdmi 1, it will stay on hdmi 1 and I can watch my fire tv stick normally. As soon as I turn the rpi2 back on, the tv switches to hdmi 2 (or whichever hdmi port I have the rpi2 plugged into).
I am pretty sure the problem is with the fire tv stick and not with the rpi2, because I have other devices on other hdmi ports and they don't have any problems. I have already tried switching all my devices to different hdmi ports and it doesn't make a difference, the fire stick will always switch back to the rpi2's hdmi port as long as the rpi2 is on.
Anyone have any ideas? I have already looked through all the settings on kodi to see if it does something funny that would interfere with the fire stick but didn't notice anything.

Yeah, your title is pretty misleading. I thought your FireTV stick was falling out of the HDMI port.
Maybe change the topic title to "Fire TV Stick is disabled when another TV HDMI port is used".
Anyways, I would be willing to bet your paycheck that your problem is a poor power grounding issue on your Raspberry Pi. You may need to put a Cheater Plug on the Raspberry Pi power supply, or on your TV. Or, if there isn't a ground pin on your Raspberry Pi supply, you may need to flip the power supply plug 180 degrees in the outlet. Or, if you have a UPS back-up supply powering anything, you will need to have all the equipment connected to the UPS, or none of the equipment.
Something like that.
