Hdmi port no longer working on Satellite Pro R50-B

Q: Hdmi port no longer working on Satellite Pro R50-B

I have been using an AOC monitor as a second screen attached to my laptop via HDMI under Windows 8.1.

The monitor is telling me that there is no signal from the HDMI port. I have changed the cable and changed the port on the monitor, but it still is not working.

Can you help?

I have a Thinkpad W530 and an LG smart tv.I used to send the notebook display to the TV via an HDMI cable.Now it does not work any longer: whichever HDMI input I choose on the TV the notebook does not shows on the TV screen. The correct HDMI input appears in the list on the TV screen, but when I select it a 'no signal' warning shows up.What option/driver should I check?Carlo

Is there a driver for the HDMI port for the Satellite R830?
It no longer connects to a TV.

I have tried different TV's but still nothing.
Also there is no HDMI under the device manager under the control panel, should there be?

Many thanks for any help or advice.

A:Satellite R830 - HDMI port is not working

I don?t know what Windows system you use on this notebook but the HDMI driver isn?t available since the HDMI port driver is part of the system and should be recognized automatically.

For HDMI sound capability you should install the right sound driver and should enable this in control panel -> sound -> playback device

In order the HDMI (digital out) would not be listed there, right click and choose:
show disabled devices, show hidden devices.

Usually the HDMI connection isn?t very tricky. Everything should run automatically.
Connect both devices using HDMI cable.
Power up the TV, then computer.
Now use the function key (FN key) video output combination in order to switch to video out (HDMI).

Note: the right HDMI channel should be chosen on your TV

That?s all

I have a Satellite Click 2 Pro since March 2013 (actually, it's property of my employer). I've been using it on an external monitor through the HDMI port in the docking station, connecting with an HDMI-to-DVI cable to a 24-inch Dell monitor.
The first year this worked perfectly and to much of my satisfaction, but then the port started not working sometimes, as the monitor lost "connection" to the computer and would go black and idle for some seconds. This slowly became more common and now it never shows anything.
I don't know if it's a hardware or software problem, but I'd guess the former.

I'd like to get the computer fixed. Cleaning the port didn't solve the problem.
What could it be?

Being localized in Bologna or Rimini, Italy, where could I get the computer fixed? I need a repair shop who's willing to work, in terms of repair order and payment, with the public administration, as the computer is property of the University of Bologna.

For the first couple weeks I was able to run 3x 1080p monitors just fine using two display ports and an hdmi port. This morning when I docked my computer I could only get two to work. I can disable one then enable another and get all three working but only in sets of two.  I tested two of my coworkers laptops on my dock and all three monitors work fine. Also when I boot all three work until the Windows splash screen then one goes dark.  If I try to enable the third one: It acts like it's connected but the display remains dark and I lose my mouse cursor. I can stll move the mouse and see the hover overs but the cursor is gone.  I'm thinking this is a windows driver/firmware issue. In device manager I see all three:   But can't seem to get all three to work at once.  I've tried reinstalling both the Thunderbolt drivers and the display drivers with no luck. Any ideas? I'd like to avoid completely reinstalling Windows as I know that'll probably be a suggestion.

The HDMI port on my Satellite L500 laptop is not sending information to my sony bravia tv. All was working fine up until a couple of days ago. When i plug the hdmi lead into the port, it seems as if the laptop is aware it's plugged in as the screen flickers. The fn +F5 keys do as they should, but no picture appears on the tv. The tv shows a lead is plugged in also and again the screen flicks to say a source is there but then remains black. I can't see an issue in device manager and all drivers are saying they're up to date. I have also tried a new hdmi lead but nothing. Can anyone help with this?

Try running a System Restore back to a previous point when it was working.

Hi all...

I hope you can help. I bought my new Satellite in about October last year and from day one I've been experiencing problems connecting an additional monitor. Originally I had an old monitor with a VGA connection, and of course this computer only has HDMI.

So I bought an adaptor, which didn't work. I tried connecting my computer to the tv monitor with the HDMI cable to test it, but it still didn't work. It's still under warranty so I sent it back to Toshiba service, who couldn't find anything wrong with it, and returned it to me.

So I bought a brand new monitor, (a BenQ), and a brand new HDMI cable. Indeed for some reason it worked for a couple of months.and now doesn't. The computer won't detect the monitor, and the monitor says there is no cable plugged in when I attach it to the computer.

I've tried everything and it's driving me crazy.

A:Satellite S50T-B - HDMI port issues


The VGA-HDMI adapter will not work because HDMI provides digital signal and VGA (RGB) port supports analogue signal. You cannot mix both!

Anyway, back to your HDMI issue.
Please try this workaround:
First of all go to BIOS (F2) and set the BIOS back to default settings (F9) and save changes (F10).
Now connect the notebook and TV with an HDMI cable. Both units should be OFF during the connection.
Then power up the monitor and then the notebook.

As far as I know you have to use the function key: FN + F4 to switch to external or internal display.

Please check this!

Hello All,

Well this is starting to drive me to distraction and Im hoping theres someone who can put me out my missery lol.

I have been trying to hook my laptop (toshiba satellite pro p300) up to my LCD TV via the same HDMI cable I use for my PS3 but the connector just wont fit. I keep finding all these posts in various forums saying how they cant get sound out the HDMI connection...that would be great, as at least that means they have them connected.

Are there different connections for HDMI? The one I have is diagonal connector but the port on the laptop is more square, and just doesnt fit. So if there isnt a connector, does that mean I have a funky port, on the laptop.

There is also the matter of connection my laptop to my amp that controls the surround sound system. What connection is best to use, as there is no real audio out connections?


A:Satellite Pro P300 - HDMI output port doesn't fit


Can you please tell us what Satellite Pro P300 you have exactly? I mean the exact model number.
Maybe you can also post a picture of the HDMI port. Normally there are no different HDMI ports, all have the same physical dimension.
I?m not PS3 owner but maybe it has a special connector. Have you tried another cable?

Regarding the audio connection I use the normal line out port for my external speakers. Did you test this?

The graphics are just onboard graphics ATI Radeon 4250. I've been running this to my LCD Tv for almost a year now. Yesterday I unplugged it for a while and left it running, eventually plugging in a VGA monitor. When I went to switch back in the HDMI it doesn't recognize the TV whatsoever.

I go into properties and click detect, nothing. I went into the CCC and nothing. I've tried multiple cables and whatnot and still nothing. Seriously what the hell happened that all of a sudden my HDMI port won't work?

First time poster, nice to meet ya...

anyway, On my laptop, i used to be able to run video and audio to my entertainment system no problem. However, after an HDD meltdown, followed by a warranty replacement of the HDD, I reinstalled the drivers for my audi and video, and now no sound or video on my entertainment system. The drivers are not exactly the same as what I had before the HDD replacement. For example, the radeon drivers/software is newer, and I finally actually installedthe sound blaster software on my PC ( wasnt installed previously ).

I have looked, and the entertainment system is showing up as the destination of the sound ( no sound coming from PC while connected ), and also it is showing up on my video controller as being connected.

Other PC still works with this entertainment system as it always has. I am almost positive that the problem on this PC happened after the HDD replacement.

any ideas?

Thanks in advance!

Your laptop might be outputting a higher resolution than the TV can display. You mentioned it was a DLP TV so its probably only 720p, so if you laptop is outputting 1080p it might not work.

Ok so after trying EVERYTHING I can think of to get this resolved.... I'm slowly losing my mind.

Basic history. For a couple of years now I've been using my Sony Bravia HD as my display monitor for my PC. Since using it I've hardly ever had a problem with it save for one. This one problem is something I've experienced only a couple of times in those years and I have it again now with ALL the same symptoms except this time I haven't been able to solve it!

I came home one day (with my PC left running) and there was nothing on the display which I thought was weird because I'd done nothing before I left except left it to download.

I've now.... after spending hours tinkering, been able to get my display back by hooking it back up to my monitor but I WANT it back to my HD Sony Bravia.

Well, I've updated the graphics card (which really shouldnt have been neccessary as the driver was fairly up to date and worked fine before anyway).

I've tried going into display settings but there's nothing to directly TELL windows to look for a different display device.

I've tried different HD slots and nothing, different cables and the cables work fine.

The interesting thing is this. one of the symptoms I had before when I had this problem was that when I plugged in a lead from the PC to the default dell monitor AND also plugged in a HD lead for hd to hd from pc to tv, what I get is a blank desktop on the dell monitor. everything suddenly dissapears (no icons, taskbar NOTHING, just ...

Hi guys,
I recently upgraded to Windows 10 from Windows 7 on my HP G60 125CA laptop. I never had this issue with Windows 7, but ever since upgrading to Windows 10, I can no longer use the HDMI port to use an external monitor. The problem is, the computer recognizes the external, as it makes a sound AND shows there's two monitors (the laptop and the external) in the Display Settings, but I get no signal on any monitor I use, no matter what HDMI cord I use. I've tried adjusting the resolution to 1920x1080 for my HDTV and that didn't work. I still get no signal. I have the latest NVIDIA graphics driver. NVIDIA GeForce 82000M G is the video card. I've tried re-installing, completely removing the driver, doing a clean install, installing an older driver and none work. I even tried extending, duplicate, show desktop only on 1, show desktop only on 2, etc.

If you guys could help, I'd greatly appreciate it.

HI All

I have moved to Windows 7 from Vista, finally

Computer - HP 8710w, Intel Centrino vPro, Nvidia Quadro

I connected my HDMI cable to TV Hdmi port and PC Hdmi port but no signal on TV at all. With Vista it was plug and play (just needed to adjust audio settings on PC).

I have tried downloading updated drivers but to no avail. While connected pressing the Fn key and F4 hey does nothing, the computer has no idea that something is in that port. I think the port is somehow inactive or physically damaged.

How may i check to see if the port is working and how do i check if its software related?

Many thanks

A:HDMI port not working

Are you running more then one monitor at a time? If you are then you need to right click on your desktop and select "Screen Resolution". Then find the TV on the display device drop-down menu. Then check the box "Make this my Main Display".

Let me know if that works, if not I can help troubleshoot the problem some more.

Hi all,

I've just recently got myself a new laptop (specs at bottom of message) and took it around a friends house and plugged it into their HD TV via HDMI - all worked well, the laptop recognised the TV straight away, optimized the display and away we went.

A few days go by and I decided to upgrade my own TV from an SD to an HD TV (Bush BLED24FHDL8) yeah I know cheap as chips, but it's going alright so far ... well except this problem pmsl.

Within 5 mins of setting up the TV channels I decided to plug my HDMI cable into the laptop and then into HDMI 1 slot on the back of the TV, I changed the input of the TV to HDMI 1 and.... nothing.

Going into the display settings of my laptop didn't show a 2nd display, so I changed various settings trying to get it to recognise the tv, but nothing, still no signal showing on the TV, and nothing showing on the laptop.

So I changed over the cable to the HDMI 2 slot on the TV etc and still nothing on the laptop, I fiddled with the settings again and still couldn't get the laptop to recognise there was a 2nd display, nor get any signal on the TV.

As a last resort I unplugged the HDMI cable and tried the VGA cable I have - and this decided to work, although no sound as I didn't have those cables plugged in.

When I plugged the VGA cable in, the TV and laptop recognised each other straight away and I didn't have to do another thing.

Hello all,

I have had many happy years using my Toshiba laptop without problem. The operating system is Vista Home Plus.

About a year ago, my son dropped the machine, which resulted in the display cracking. In order to keep using it I plugged in a spare mouse and keyboard, and linked it up to a flat bed monitor.

Using Fn+F5, it has worked perfectly as a defacto desktop for ages until relatively recently: the cable linking the laptop and the monitor became detached which resulted in the monitor going into sleep mode. When reattached, the display did not return and I have had persistent problems ever since. Using the F5 key now has no effect.

Points of note

- as the machine powers up, the external monitor displays the usual text, but when the Windows logo appears, it reverts to sleep mode and the laptop continues to boot up cleanly.

- when I boot up in safe mode the F5 key functions perfectly

- I have cured the proble previously by booting up in safe mode and restoring back to to a checkpoint taken a few days prior. This is a temporary fix, as whenever the machine is powered down it reoccurs. What is interesting though is that there always seems to have been a recent Windows Automatic update downloaded when I look at the list of recent system checkpoints and what triggered them!

Getting thoroughly fed up with the whole thing now. Any help very much appreciated.


A:Satellite Pro M - F5 Function Key no longer working


It?s really not easy to say what the reason is for this problem but it would be interesting to know what notebook you have exactly.
Can you add this information, please?

Anyway, at the moment I would recommend to update the display driver and BIOS. Both you can find on the Toshiba website:
http://eu.computers.toshiba-europe.com => Support & Downloads => Download Drivers

Before you start the BIOS update close all running background programs, also your antivirus and firewall. You should be logged in as administrator.
Furthermore I would recommend removing the old display driver before you install the newest one. After removing restart the notebook and clean it using CCleaner. Restart again and install the newest version.

I hope this can solve your issue and by the way: Have you installed SP for Vista?

I have tried everything but nothing works. I am running an ATI 4200 which is on the motherboard. Can this be fixed or would I have to buy a new graphics card to get it working again. I did swap the cables but still get the same results. Does anyone have any ideas because I have run out of them???

A:HDMI Port not working anymore

The only way to fix it is to buy a new motherboard, do yourself a favor and buy a new video card instead, Dells are not worth fixing. But if it`s under warranty well then that is a different story.

If that`s a laptop then your ONLY option is to replace the motherboard, very simple to do.

Intel recognizes the built in monitor, but doesnt see the external monitor.In the NIVIDIA contorl panel under system topology it details the HDMI port, its connected. So I got my IT people involved. They couldnt figure it out either. They tried everything. They believe that since NVIDIA sees the external monitor, but "Multiple Display Cloning" is "Disabled" (Unable to enable it) that NVIDIA doesnt recognize the built in display, it thinks the built in display is the monitor. When the external monitor HDMI is unplugged, the NVIDIA control panel clears out as if no monitor exists at all. This is a brand new HP zBook that I have had for a couple months. Been fighting this issue ever since. Desperate to get my monitor working I recently went and purchased a VGA to DVI converter and DVI to HDMI converter. That doesnt work either. I feel defeated, crushed by an HDMI port.

Hello HP community, I have a HP 15 TS Notebook PC and the HDMI port is not working. Yesterday (9/17/2016) it was working just fine. I had my laptop connected to my TV via HDMI and it working. Today my computer did an update and after the update my computer did not read the HDMI cable. I am not even sure what the update was for, but I turned it off this morning and it updated and then updated again when I turned it back on later today. After the update the computer does not read the HDMI cable. Everything else works fine. What should I do? Thanks!
