Hdmi to VGA issue

I use an HDMI to VGA converter to an external monitor. Recently the external monitor began to flas off and on periodically, and then completely went blank. Tried rebooting, and a second vga monitor with the same results. Purchased a new adapter as well and at first it semed to resolve the issue, but then it returned.
I turned the Laptop off overnight, and restarted, and the external monitor began working again.
That night left the LT go into sleep mode overnight, and when woke the LT the next morning the external display again did not recover.
Turned the LT off again and let it set for about an hout. Turned back on and the external monitor now works again.
I've reset the power options to nev ?er turn the monitor off, but let the LT go into sleep mode to attempt to determine where the issue is.
Not sure if it's heat related or sleep mode related.
Warranty expires in August so want to get to the bottom of this if possible.
Suggestions?

Hi there @Spark_Ric
Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.
I understand that you are trying to use an HDMI to VGA converter to connect to an external monitor. I am happy to help you with a direct HDMI connection, to an HDMI device to test the functionality of the HDMI port. Beyond that I cannot troubleshoot an HDMI-VGA adpater that may not be compatible.
If possible do you have an external HDMI device you can connect to, and test with, or if you prefer as you say you are in warranty, you can try calling our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Again, it is likely that phone support will want to eliminate the adapter from the chain and test with a direct HDMI connection to verify the HDMI port.

I cannot get my monitor cable to fit in the hdmi to vga adapter

Hello
I was wondering if anyone is having the same issue as me. I'm trying to plug my new mac mini into my Dell flat screen monitor. It doesn't seem to fit my HDMI to VGA cable so I'm assuming that my cable is in fact a DVI? The cable is actually a little too big for the VGA adapter and no spots for the screws. If anyone could help me further I'd really appreciate it.

Hello, what does the connector on the Monitor & Cable look like?
VGA & DVI...

HDMI to VGA output possible (or will I get HDCP errors)?

Hello.
Does anyone know if it's possible to use an HDMI-to-VGA cable with the ATV (gen2)? I purchased an ATV for my parents and they can't use it as every time they go to play a movie rental or stream Netflix, they get an HDCP error saying "the connection doesn't support HDCP".
I have confirmed their TVs HDMI (v1.3) ports all supports HDCP and I have also used various HDMI cables, but nothing I do works — it always results in an HDCP error.
They have a VGA port available on their TV and I'm wondering if it would be possible to use an HDMI-to-VGA cable to play content? Or would this also result in an HDCP error?
My only other option seems to be to return the ATV?
Thanks,
Kristin.

On my parents TV (32" LG LCD), I have tried various cables, etc. but can never get the ATV to play protected content. The first thing I did was take it home and plug it in, using the exact same cables, to my TV (42" LG LCD). Worked fine. I then tried with the 3 other HDMI cables I'd been trying at my parents house. All worked fine.
This initially led me to believe it was an issue with their TV. So, I attached a number of other HDMI devices (that require HDCP) to their TV, and all worked fine, no errors. I then dealt with LG on this and they determined that everything was fine with the TV, especially since other HDMI-based devices requiring HDCP had no issues.
So, at this point, the only thing left is that the ATV just doesn't like their particular TV. These boards are flooded with this issue on various models/brands of TV. I don't think there's any real solution other than returning the ATV. It's a bummer. I absolutely love my ATV and I know they would have too. Once again, shoddy copyright protection wins again.
Thanks,
k.

HDMI to VGA no audio

As soon as I plug in my HDMI to VGA converter I now lose audio from the computer / video. It was working fine last night so I am not sure what changed. Haven't done anything affecting audio settings.
I'm running Windows 8.1 and I've installed all updates received since I bought the laptop on 3/18. Is there a special setting I need to work on to resolve?
Many thanks!!!

Hi @Zullyfra ,
Thank you for your inquiry.
I grasp that when you connect your HDMI to VGA converter you loose the audio from the computer video. It was working fine previously and you have not changed any settings.
When you connected the first time was the notebook on or off?
You may want to try connecting both devices first and then turning on the external device first and the notebook last.

Input signal out of range with HDMI to VGA adapter LE1901w

Hi!
Recently I acquired an LE1901w monitor to use as second screen. I'm trying to connect it to my Toshiba u925 using an HDMI to VGA adapter (because neither the monitor has a HDMI port nor the notebook has a VGA output).
I'm getting the message "input signal out of range" asking to change to 1440x920 @ 60Hz and it keeps showing until the monitor goes to sleep even when I change the settings as per requested.
I have an integrated Intel HD Graphics 4000 and i'm using the default Windows monitor drivers for Windows 8.1
Any comment will be helpful
Thanks

Hello @fbinim,
I understand that you are getting the message "Input Signal Out Of Range" and it is asking you to change to 1440x920 @ 60 Hz. I suspect this is a driver issue and you will need to ensure that your drivers are up to date on your computer. Just to be sure I would recommend if you could to move the HP LE1901W monitor to another computer and ensure that you do not have the problem there. If you do have it on another computer The issue you are experiencing appears to be a physical issue. Please call our technical support at 800-474-6836.

The best HDMI to VGA adapter

I have a U510 with the useless mini-VGA and no adapter has worked for that, so now I am looking for a good HDMI to VGA adapter. What is a good one for under $40? (Online or at Best Buy, RadioShack, or Staples)
Thanks!

There's no such thing as a HDMI to VGA adapter. HDMI is purely digital signal, while VGA is pure analog signal. You'd have to get a converter that not only could change the shape of connector, but also decode digital sitnal and encode is as analog one. I don't even know if anybody makes such a thing. Why would you use VGA anyway? HDMI is superior in quality and functionality. VGA is susceptible to e-m noise too.
EDIT: Ok I did look it up, and there are HDMI to VGA converters. I must admit I'm surprised. Still, I'd avoid it if possible. If you do need it, I can't recommend one as I never used one, but maybe using the one you can get from Lenovo might be a good idea?

Projector HDMI to VGA

Hello,
I try to connect my IdeapadS300 to a VGA projector I use for my studies. I have a HDMI to VGA adapter but when I plug it, the image is not transmitted.
Does anyone have this problem? Is there a special thing to do?
Thanks.

hi Masterdid09.
Welcome to Lenovo Community Forums!
You can try checking if the Projector is being detected
Right-click on the Windows desktop and click Screen resolution to open Screen Resolution in Control Panel.
You should be able to see the projector as a display there (if not check the cable and then check the source setting on the projector if its on VGA)
Click on the projector display then choose the recommended Settings. Hit apply
Link to Picture
Now Press Fn+F10 on you keyboard or F10 only.
You will be given a Screen setting Selection.
Choose you Preferred settings by clicking the option.
Hope this helps,
Cheers!

Ni supplied hdmi to vga converter

I hope this is right board, my apologies if its not.
Has anyone else had a problem with screen resolutions when using the hdmi to vga converter supplied with a 8133 controller?
the controllers gpu (ati radeon e2400) is more than capable of 2048*(i forget now)
I have a iiyama prolite x2472hd which again is more than capable
through the adaptor (hdmi to vga) i get 1600* 900 @60Hz. highest resolution and I can get it upto 1920*1080 but the refresh makes it unusable.
If i use the controller without the adaptor i get 1920*1080 at 70Hz (i believe it will show at higher resolutions).
if you want want high resolutions from pxi controllers do not use the supplied adaptor
i wanted to post this problem with the solution so other people could find some info as there is little around but any comments greatly appreciated
Please remember to accept any solutions and give kudos, Thanks

Macbook Retina HDMI to VGA

I'm looking for the best solution to connect my Macbook Retina to VGA projectors at work. I see two adapters on the Apple store both with bad reviews. Has anyone had good sucess with any adapters that go from HDMI to VGA?
Thanks

Below are the two adaptors I use that work fine.
I use the VGA at work for the connection to conference room projectors
I use the DVI connection to a $100 flat screen second second monitor I have
I'm happy with both. The only issue is, since I plug/unplug the thunderbolt cable several times a day, the connection moves and the monitor sometimes looses the signal for a second. Thunderbolt is just not a tight connection like DVI and VGA and doesn't hold it in place strong enough. Nice that its small but not a good connector over all...the number one requirement of a connection is that it is tight and secure...thunderbolt fails this.

Keynotes + iPad2 (AirPlay) + AppleTV + Digitech HDMI to VGA Converter.

Hi,
I am going to buy a iPad2, Apple TV and DigiTech HDMI to VGA/Component and LR Analogue Audio Converter, which I want to connect to my data projector in my classroom. AirPlay on the iPad 2 - http://www.youtube.com/watch?v=10nfcwTHbIA
I want to use Keynotes, and mirror iPad Apps onto the projector.
I will provide various students with iPad2 devices and let them interact with the lesson as well.
Is this possible with Keynotes, and is there another option to regarding the connection to the projector?
At this stage I need to buy a Apple HDMI Adapter ($39), Apple TV ($129), and HDMI to VGA converter ($149). So $319 to get a wireless connection to my projector.
Does anyone have other options ?
Kind Regards
Sean Udal

I believe the only devices you need to achieve a wireless iPad 2 mirroring experience on a display is an Apple TV 2. When iOS 5 comes out in a few weeks the iPad 2 will have full bore wireless mirroring using the Apple TV 2. The Apple TV 2 outputs an HDMI signal so if your display has HDMI inputs you're home free. However, you like me (I am also a teacher), have the nasty problem that our classroom projectors only accept a VGA input (probably composite too). That Apple TV 2 is sending an encrypted HDMC signal to your projector via it's HDMI cable. So, you need a HDMI to VGA converter that can overcome this encryption. I just bought a HD Fury 3 HDMI to VGA converter that has a chip in it to deal with the HDCP encryption. Sadly, I just hooked this system up in my classroom and it doesn't work. I posted this information in the other thread you started asking about this same issue. One of our school's tech personal is going to see if he can resolve this but I am not optimistic. There are many posts in other forums that claim great success with the Fury 3. If anyone has some insight regarding this I'd love to hear it. My projector is a new Epson short throw projector. It cost somewhere in the range of $1600 - $2000. Sorry, can't remember the specific model off hand. Anyway, even though it has no HDMI inputs, it is not a cheap projector.

Ideapad S400 Touch - HDMI to VGA problem

Hi,
I need to connect Ideapad S400 Touch to projector which has only VGA input. Therefore, I've bought such converter:
http://www.amazon.com/Black-Input-Adapter-Converter-Laptop/dp/B007KFVQXI/ref=pd_sim_e_4
Unfortunately, whatever I connect through it (projector, tv, PC monitor) I always have no signal...
I tried HDMI direct connection toTV - works
I tried HDMI to DVI converter and connect to PC monitor - works
but when I use HDMI to VGA like one mentioned above - always "no signal"
Please help. I bought this laptop and now find it useless as I present on beamers very often and am completly stacked now...
Any suggestion would be highly appreciated!
Thanks!

hi ro174748,
Welcome to Lenovo Community Forums!
The connection you need is a active coverter.
Passive connection just passes the signal and relay the signal without converting it.
Active connection converts the signal and relay it to the other end.
HDMI send / recieve digital Signal while VGA send / recieve analog
Your corrent covertion will not work if the device cannot recieve digital signals through VGA.
You will need an active converter such as this
http://www.newegg.com/Product/Product.aspx?Item=N82E16812400359
HDMI to DVI operates with Digital signal so no covertion needed, that's why it worked.
Here is a simple discussion about this issue.
Hope this helps

I bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.\\\\\

i bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404
