Display to HDMI output

I have a ThinkPad Edge E520. I just purchased an HDMI cable and want to display a presentation on a TV. The laptop is not recognizing the TV as an output destination. I have tried a different cable, same problem. I tried plugging a different laptop into the TV with the HDMI cable and it did work. With those variables resolved, it appears the problem is strictly with the ThinkPad. I have adjusted as many settings as posisble under the "screen resolution" interface but it still doesn't work. Help!

How can I connect my 24" cinema display to a mac book pro retina HDMI output?

Hi folks,
I would like to have a macbook pro retina running three external displays (this is technically feasable):
2 times a 27" Cinema displays through thunderbold ones (connecting them to the Thunderbold output, daysy chaining them)
1 time a 24" Cinema display through mini display port (connecting it to the HDMI output as the resolution matches on both ends 1920 x 1200)
Any idea which adaptor I would need as most of them are only working one way (the wrong way!..)?
Thanks for you numerous inputs ;-)

HDMI output to monitor not displaying all colors

I am trying to use a second monitor on my Satellite S55t-b5152 and am able to get 1920x1080 output from the HDMI port through an adapter to either VGA or DVI into my external monitor, but with either adapter the colors look washed-out and not all the colors that are displayed on the internal monitor show up on the external monitor. For example the position indicator in scroll bar on some apps shows up on the internal monitor, but disappears when I drag that window onto the external monitor. I've tried multiple monitors and they all have the same symptom. I've investigated this some on external forums and it seems to be that the HDMI output under some conditions assumes that it is connected to a TV instead of a monitor and it limits the output color range. On some graphics drivers it is possible to override that assumption and get the full range output from the HDMI port. I haven't found a way to do that for the graphics driver on the S55t-b5152. Has anyone figured this out?

Satellite S55T-B5152
through an adapter to either VGA or DVI...
Just want to comment that I'm not at all surprised that an adapter does not produce true colors. I'm sometimes amazed they work at all.
Yours is HDMI 2.0 which complicates things still further.

XBox HDMI output to Apple Cinema Display DVI input

I have an iogear DVI KVM, a mac pro and an xbox360 with HDMI output that I want to somehow convert to DVI so I can use my Cinema display to game on.
Is this possible?
Out of curiosity I bought an HDMI to DVI gender changer to see if I could hook it up that way.
No result.
I figure a conversion must be needed to make this work.
has anyone done this, If so, could you post your hardware setup or recommend a converter.
thanks

The splitter sends the same signal to both displays, but they need different resolutions to work.

Hdmi output not found under playback in the control panel

I am trying to get sound to go through my tv with my HDMI cable. I looked in the control panel under sound - playback. I do not see the option of the hdmi output. I have right clicked on the speaker and clicked disabled and it still does not come up.
I have idt high definition audio codec driver on my computer. Is it compatible?
I have also tried to connect an rca cable to the headphone jack and hook it to the tv like that and sound still didn't work?
Do you have any suggestions?

Hi again tfinley,
It is good to hear back from you!
Since you have updated all of the original drivers on your system, and your notebook still does not display an HDMI audio option, I recommend returning your system back to a previous restore point when this option was available. This can be done by following the steps in this document on Using Microsoft System Restore (Windows 8).
Should the problem continue, I suggest performing a backup and recovery of your operating system. This can be done by following the steps in this resource on Backing Up Your Files (Windows 8), as well as Performing an HP system recovery (Windows 8). This should return your system back to factory defaults.
If the issue persists, please call 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.

HDMI output not working with AT 200 under ICS

Hello,
I connected the HDMI output to a Sony KDL 32 E 5500. It simply does not work.
The same TV HDMI input works fine with a DVD player.
The AT 200 tablet is under ICS (upgrade in France).
I tried both HDMI configurations : full screen and video window.
Should I send it back for repair ?

Hi
There are two outputs: Mirror and video area only.
Mirror:
External device copies the image on the tablet screen
Video area only:
The external display device shows the playback when open a multimedia
But You should firstly check the Android Settings:
Under the option Screen you will find the option HDMIO video mode
Tap this to switch between the HDMI video output mode.
You could also try to connect the HDMI device under following conditions:
- Tablet is turned on
- Tablet is completely turned off
- when you connect TV or external monitor to HDMI port, then display output is set to HDMI
- when you plug and replug the cable, wait at least 5 sec before you replug the HDMI cable.

Can't get audio HDMI output to work on ViewSonic VX2453 monitor

I have a 13" mid 2011 MacBook Air and a new ViewSonic VX2453 monitor. I used the Monoprice mini display port to HDMI converter with audio and connected the monitor to my computer's thunderbolt port. The video works perfectly, but the sound isn't working at all. I set my computer's sound output in settings to VX2453 series (type: HDMI), and I set my monitor's audio input to HDMI. Nothing. I also tried changing the frequency in Audio MIDI Setup, which someone recommended on amazon for the monoprice adapter, but that didn't work either.
I tested the monitor's sound by switching audio input instead to "audio in" and connected to my headphone jack, and that worked so the monitor's sound is fine.
Any advice would be greatly appreciated! Thanks.

Hi - I'm just setting up my VX2453, as well. I got sound to come out of it via the same HDMI output setting on the Mac as you describe, so I think you're doing the right thing.
Be sure you've selected the correct HDMI input (?).
Related, on my monitor, the audio can't be adjusted anywhere other than through the cumbersome volume control on the monitor. That is, when playing over the HDMI on the monitor's speakers, the volume controls on the MacBook Pro no longer respond (grayed out).
Anyone know how to make the volume controls on the MBPro respond under that setup?
Thanks.

HDMI Output Not Working on Lenovo B540

Yesterday morning the HDMI output on the back of our Lenovo B540 stopped working all of a sudden. I have a projector as a secondary monitor that I use for media applications which connects via a SVGA to HDMI converter which has worked flawlessly for months until yesterday. My first inclination was the converter but after some troubleshooting I have determined that the issue is somewhere in the Lenovo AIO system. Below are the steps I followed to make my determination:
1. Tried connecting Lenovo to another known-good monitor and nothing. The display property picks up the monitor's attributes like make and model and even resolution but no display.
2. Plugged projector into another computer WITHOUT converter and it WORKED.
3. Plugged in project into the same computer that I used in step 2 above WITH converter and it still WORKED.
Steps taken to resolve (without success yet):
1. Updated Intel HD Graphics display driver to 10.18
2. Installed latest graphics chipset update from another forum post I found suggesting that might be the issue.
3. Changing "Source Select" from bottom right hand corner of system (icon with arrows forming circle) but it ONLY shows "PC" option. Not sure if that's the issue or not, but wanted to mention it.
My next step is to completely uninstall the display driver and try seeing if second monitor shows display.
My last step which I would like to avoid if all possible is a factory reset as I have many applications installed that I would like to avoid reinstalling if at all possible.
Any further assistance with this issue would be greatly appreciated. I feel like it's a driver/configuration issue, but I'm not finding it yet.

I wanted to reply that I just discovered that my Lenovo AIO no longer likes my converter. I'm not sure why as I have proven that it works by using it on another device. The other device is a laptop running Windows 7 Pro.
On a haunch, I plugged in my HDMI TV which has a native HDMI connection and it WORKED. So, I suppose I'm back to the drawing board and this is indeed not a Lenovo hardware issue.
Does anyone know of any issues with using a HDMI to VGA converter on a Lenovo B540 AIO? Link below:
http://www.startech.com/AV/Converters/Video/HDMI-to-VGA-Adapter-Converter-for-Desktop-PC-Laptop-Ultr...
I have the one above but I just noticed there is a HD2VGAE which I'm not sure what the difference is.
Thanks!

HELP! Lightroom Crashes Only with Adjustment Brush and only when using HDMI output!

This is very frustrating. I use my Acer N56V laptop to teach Lightroom workshops. I use a 32 inch television as a display. When I have my laptop attached with an HDMI cable and try to use Lightroom's adjustment brush, it crashes. Either the screen and computer just shuts down or I get the Blue Screen of Death. I can do anything else! I can edit in Photoshop, do anything else in Lightroom or even Silver EFX Pro. I can even click on the adjustment brush. But the minute the brush hits the photo (and not before), the computer crashes. If I don't have it attached to the HDMI or if I use a Serial cable, no issues. It's only the adjustment brush and only the HDMI output.
I called Adobe and they said it was because my onboard video card was primary and not the Nvidia. I called Acer and they said it's auto detect. I also tried making the Nvidia card primary and it still happened. Any ideas???

You have switched the overlay mask to always show. Fortunately, it's easy fixed i.e. tap the O key. Shift+O will cycle the overlay through various colours
Other Adjustment Brush and Graduate Filter shortcuts and modifiers are listed them below:
Open Adjustment Brush - K
Open Gradient Tool - M
Show/hide Pin - H
Always Show - Shift + Cmd/Ctrl+H
Show Selected/Never Show - Shift+H
To increase Amount - Right Arrow
To decrease Amount - Left Arrow
To increase/decrease brush size - ] / [
To increase/decrease feather - Shift+] / Shift+[
Set Flow Amount - Number Keys
To commit and/or start new a brush stroke or gradient - Enter / Return
To delete the selected pin - Delete
Holding down - Alt/Option key activates erase mode
Toggle Auto Mask On/Off - A
Pressing O toggles on/off the overlay
Shift+O cylces through alternative colours for overlay
To constrain gradient to vertical/horizontal - hold down Shift plus drag
To invert the gradient - '
To scale from center - Alt/Option plus drag

Mini display to hdmi adapter problem

Hi,
When I connected my mini display to hdmi adapter to hdmi, and hdmi cable to my ASUS PA238QR monitor, my early 2011 MBP 13" detects the monitor, but the monitor shows "hdmi no signal".
I tried unplugging everything, including the adapter and hdmi, but to no avail. I tried putting my computer to sleep, and waking it up, still, nothing seemed to be the cause of the problem.
I read through some old discussion on this issue, and nobody seems to have a solid solution besides purchasing another adapter.
I tried booting into win7 and still, the monitor shows "hdmi no signal".
I am 100% sure my monitor and hdmi works becuase when I used other laptops it's fine.
Thus, I'm suspecting it's the mini display to hdmi adapter's problem.
Is there a way I can make sure that my macbook pro is outputting the signal?
Any recommendation or advises are welcomed. Thanks for reading.

If you've an HDMI port on your television, you could always try that.
I've used this adapter from Monoprice successfully - not bad for under $7.
Give your TV a try - if no go, then you'll know that it's an adapter problem.
Good luck,
Clinton

Mac Mini HDMI Output Problem w/ LG L246WP

NOTE: This appears to be unrelated to the "screen flickering" that has been noted previously.
I'm using a fresh new Mac Mini 2012 with an LG L246WP LCD monitor. The monitor has HDMI, VGA and Component video inputs.
When I attach the monitor to the Mini DisplayPort output, using a Mini DisplayPort to DVI adapter connected to a DVI to HDMI cable, the display functions properly at all resolutions - including the native 1920 x 1200 resolution that I use it at normally. All resolutions are clearly displayed in the "Displays" System Preferences pane. The display looks perfect, functions properly.
When I attach the monitor to the HDMI port using an HDMI cable, the display does not fucntion properly. The display is shifted about 80-100 pixels to the left and about 20 pixels up, creating black bars on the bottom and right sides. Because of this, a large portion of the display is not visible including the menu bar and most of the left side. Additionally, the settings are reduced to "Best for Display" or "Scaled", with resolution options under "Scaled".
This is not acceptable. I had planned on simply using the Mini DisplayPort output as a workaround, since I already have the DVI adapter from an old setup, but I need to use Thunderbolt to access external hard drives for rapid data transfer. One of my Thunderbolt accessories does not have two ports, so I can't simply add the Mini DisplayPort adapter to a chain. The HDMI port needs to function properly with my monitor.
It's important to note that this monitor has functioned properly with many other comptuers running OS X, Windows and various Linux flavors and it hasn't ever done this before. I've tried several different HDMI cables, ruling that out as a problem. I've tried the HDMI to DVI adapter that ships with the Mac Mini 2012 along with two different DVI to HDMI adapters, ruling that out as a problem. I tried attaching several HDMI devices (game consoles, DVD players, etc) and they all function properly, ruling out an HDMI issue as a problem. The monitor functions properly when attached through the Mini DisplayPort to DVI adapter, so it's not a problem with the monitor. I've reset the PRAM already and the installation of OS X 10.8.1 is stock with no modifications or migrated data. I've tried the suggestions on the HDMI FAQ (although there's no "underscan" option available in Displays)
I tried to call AppleCare and after describing the problem I got disconnected with no callback. I started another ticket, described the problem, discussed the previous disconnection, was assured that I'd be called back if disconnected, and haven't heard back in two hours. So I started to dig into the problem in earnest.
This gets pretty technical.
After substantial research, it appears that this issue is related to the EDID that the monitor sends to the computer and, crucially, the way that the driver responds to it. For some reason, the HDMI port is recognizing the monitor as a CEA device instead of a monitor. As a result, it's restricting the monitor's available resolution to the native resolution that the CEA 681 Series Extension describes ("Best for Display") and all other resolutions (including 1920 x 1200) are only available as "scaled". For some reason that I can't discern, all resolutions (even the 1080i and 1080p options) have similar deformities.
I've attempted to fix this by placing an appropriate override file in /System/Library/Displays/Overrides with an edied EDID removing the CEA-enable flag from byte 127 but, even after a reboot, the OS still insists that it's a CEA device and it won't allow me to force it to recognize the monitor as a 1920 x 1200 LCD Monitor.
How did I come to this conclusion and develop the fix? A nearly identical problem description showed up on the following website, with details on how this user fixed the issue:
http://byuu.org/articles/computing/edid
They used a convoluted process that involved dismantling the monitor and flashing the EDID on the monitor itself. It fixed their problem. I'd prefer not to go through that process just because one computer has a problem with it. Frankly, I'd prefer if the new Mac Mini performed properly in the first place.
TL;DR: The Mac Mini 2012 doesn't work right with the LG L246WP through the HDMI output. Everything else works fine with it. This is very uncool. It's most likely to be an issue with the driver for the Intel HD Graphics 4000 GPU that are bundled with OS X 10.8.1. The Mac Mini 2012 won't update to 10.8.2 (yet), so I can't test it.
Anyone have any other ideas? Anyone else using a Mac Mini 2012 (or 2011) with an LG L246WP monitor? Anything simple I've missed?

Problem Resolved. But it was complicated. And a huge pain in the rear.
TL;DR: I flashed the EDID as described here. This is not recommended for the weary. Ideally, Apple should release an update OS X that will include the updated Intel HD Graphics 4000 drivers that utilize the CEA flag properly.
Here's the detailed version. As mentioned above, this isn't recommended for the weary. An improper (or interrupted) EDID flash can have seriously unpredictable effects on a monitor's performance.
Step 1: Get a Windows PC set up with a floppy drive and find a floppy disk. Use this system to format the floppy as a MS-DOS Boot Disk and copy over the "ddcw" program described at the aformentioned link.
This took awhile, but I was able to cobble together a temporary frankensystem with parts I had laying around. In installed XP and formatted the disk with XP's format tool.
Step 2: Grab EDID data from the monitor, modify it to disable CEA mode at bit 127 and make sure bit 128, the checksum, is appropriate.
This also took awhile. Several graphics cards I tried could not read or write EDID data. I ended up swapping AGP cards in my frankenstein box until I found one that worked - a generic GeForce4 4200.
Once the EDID data was written to the floppy, I edited the text file containing the EDID data to change the last two hex octets from "01 33" to "00 34" (00, to disable bit 127, and 34 is 33 + 1, which satisfies the checksum) and formatted the text file to match the sample included in the EDID_Write.zip file. Your mileage may vary - make sure the checks.
Step 3: Write EDID data to the monitor.
The link above mentioned three options: Easy (monitor's EDID is unprotected - write away!), Hard (monitor's EDID is protected - use service mode to attempt a fix), and Very Hard (monitor's EDID is protected, hardware modification is required).
Luckily my LG246WP simply needed to be put into service mode as described at the link above (menu + power) and once started up in service mode, I simply enabled "Aging Mode" (whatever that means) and attempted a DDCW write of the updated data.
Step 4: Profit!
After doing this, I powered off the monitor and powered it back on with the Mac Mini attached. The display functions PERFECTLY with HDMI out, just as it does using the Mini DisplayPort to DVI adapter.

Yoga 13 HDMI output no longer works after Windows 8.1 update

I recently updated to Windows 8.1 (big mistake!), and I am suddenly no loger able to connect my Yoga 13 to my Samsung TV through the HDMI output. When I connect the cable, the laptop screen is deactivated; the TV registers a signal, but displays a black screen with no audio. I was able to duplicate displays (even though the TV remained black), and the Screen Resolution dialogue said that no external display was detected.
I've already upgraded to all of the latest drivers, to no avail. I can't seem to find a solution on the forum or anywhere else. Anyone have an idea what the problem may be?

HDMI Output Failure on 2-Mini's After 10.9.3 Update

I have two separate (Late 2012, OS X 10.8) Mini's that are both (2.6 GHz Intel Core i7, 16 GB 1600 MHz DDR3) that have been hooked-up to identical Flanders Scientific professional HD monitors via HDMI cables from the computer output to HDMI / DVI adapters into the monitor input and they have worked flawlessly in that configuration since purchase in July of last year. THAT IS UNTIL, I made the stupid mistake of installing OS X 10.9.3 ---
I updated both Mini-A and Mini-B within a few minutes of eachother while they remained online and wired to the monitors in that identical configuration. Mini-A was the first to complete the download and install of 10.9.3 and when it rebooted, the display image did not return. Subsequently, a few minutes later, Mini-B completed the download, install and reboot with the identical result of missing display image.
Monitor info:
2 x Flanders Scientific LM-2140W, 1920x1080, 10 bit, switchable multi-input (2 x HD/SDI, YPbPr & RGB Component, 1 x SD/SDI, DVI-I / DVI-A / DVI-D switchable YPbPr / Limited RGB / Full RGB)
Needless to say, I have been fiddle-f***ing around trying to resolve the issue for more than a week to no avail. The HDMI output signal is no longer present on both computers and the only way to feed a signal to a monitor is now via the thunderbolt / mini-display port output using a Mini-Display Portt to DVI-I or DVI-D adapter at the computer to DVI cable into the monitor.
Troubleshooting Procedure included.
PRAM / NVRAM / SMC Reset (no change)
Alternate Cables (no change)
Alternate Monitors (no change)
Alternate Computers running OS X 10.8.5 via HDMI wiring schema as before (image on both monitors)
I'm no GENIUS, but I do have a modecum of experience with troubleshooting this kind of stuff and I am 100% confident that OS X 10.9.3 has caused this problem. Now, who wants to tell me how to fix it before my warranty runs out in 45 days.

So to be clear, this issue occurs on any input with the Denon Receiver. Occurs from both HDMI out and MiniDisplay Port out. Goes away when we reinstall the OS and update it to 10.9.2. Comes back as soon as we update to 10.9.3.
Cheers

Have you been able to use the Mac Mini directly attached to the plasma/LCD/projector with out going through the Denon AVR? Even with 10.9.3 installed?
I have a Pioneer AVR and I have the Mac attached via a HDMI to HDMI and all is working for me. Can your Denon do some upscaling? Some AVR, like my VSX-53 can change the scaling of the input video. Meaning if I still had my Apple TV 2 which outputs 720P only, can be upscaled in my AVR to 1080i or 1080P or even 24fps. Heck, I could even plug in an old style Red, White, Yellow cable and upscale it to 1080P and output it HDMI.
I am wondering if your Denon is able to do that and it might be set wrong. Check the owners manual for such settings. Even the plasma/LCD/project could be doing the upscaling too. So check that too.

Hi, I have a Toshiba Satellite C855D-S5237 Laptop and the HDMI Output is no longer working on my Toshiba TV. The TV does not recognize that anything is connected and the laptop doesn't recognize the TV as a display option. I have used this laptop many times in the past to connect to my TV with an HDMI cable and it worked fine. It has been a few months since I tried it but it is no longer working. Any ideas as to what could be the problem? Thanks

No sound via mini display to HDMI connector

Hi all,
I have the i7 8G ram version of the X1 Carbon (UK version) and love it. The only issue I have with it is in relation to the mini display port. I use a lot of HDMI equipment so immediately bought the mini display to HDMI connector from Grifin, see http://store.griffintechnology.com/video-display-converter but whilst video exports fine no sound is being output via the HDMI cable and end up sound via the X1 speakers which are great for personal use but useless in a large room full of people.
I already contacted Griffin support and they quickly referred me to Lenovo.
All help much appreciated.
Ben
Solved!
Go to Solution.

BenEadir,
When you have a video or sound file playing, go to Control Panel, Sounds, Manage Audio Devices.
Then when you are in Manage Audio Devices, you will se a list of devices and the external device/TV your mini display port is connected to as one of the options. Just choose the one you want and set it as your default audio device and the sound should automatically go to the selected device.
Let me know if this works for you.
Thank you for being a part of the Lenovo Family,
