HD 4600 - Can't communicate with monitor via HDMI

Hi, I have recently purchased a Toshiba Satellite S50-B-15U and I'm trying to connect it to my 3 year old AOC monitor
via HDMI (the Toshiba doesn't have a VGA port). However whatever I try I can't get the laptop to communicate with
the monitor. The graphics card in the Toshiba is a HD 4600 with a version 10.18.10.4061 driver.
Someone on another forum suggested that an older version of driver (9.18.10.3165) would cure the problem but when I try and install this on the laptop it keeps saying I have the latest driver and it will not let me change to the older version.
I should add that the laptop communicates fine with my TV via the same HDMI port and cable. Also, the monitor works
fine via VGA to my old tower PC. Any suggestions appreciated
Solved!

If you're really stuck, try out an adapter.

Hello, I have a Macbook pro retina-2013. About Mavericks I could set my 4K monitor via HDMI on 2560x1440. This I can not get through at Yosemite. Can someone help me there?

They really pushed that it would all work great! Has anyone had the same struggle? Are there any step-by-step instructions to get linked up?
Call Verizon's wireless tech support & explain your problem to them. They will provide "step-by-step" instructions over the phone.
Take notes too!
TIP: If you do call & don't want to go through all those darn promps, when you initially call, just don't say anything. The automatic voice will then say, "will connect you to a service rep."

If still the device is not showing under USB then uninstall the following services from your computer.

My latest MacMini is unable to detect my Samsung monitor via HDMI direct connect.

Hi
My MacMini (current model ie 1 week old) is unable to detect my Samsung monitor (it is about 6 months old and comes with HDMI port) via HDMI.
However, it is possible if I were to use the HDMI/DVI converter that comes with the MacMini.
FYI, I have tried swapping the HDMI cable but the result is still the same. I prefer to connect the the monitor directly to the MacMini without going thru the HDMI/DVI converter and appreciate any assistance.
Thank you in advance
jJP

Hi all
Finally I managed to get my Mac Mini connected to the Samsung monitor via HDMI-HDMI.
Below is the cut and paste of the thread I just posted which explains all.
Thank you again everyone for the advice and support.

Re: No Signal on HDMI TV After Lion Upgrade Sep 10, 2011 11:20 AM (in response to
Mac80)
Hi Mac80 I have been struggling for the past couple weeks since I purchased my Mac Mini (a few weeks back) to connect to the Samsung B2430 LCD monitor directly via HDMI-HDMI but to no avail i.e. "no connection detected" Fyi HDMI-DVI works, but I just wanted the HDMI-HDMI instead. I did exactly what you advised i.e. pull out the HDMI cable from the Mac Mini; power up & power down the Mac Mini; reconnect the HDMI cable to the Mac Mini; power up again... Wooa...lla... for some strange reason & though somewhat "primitive":-) ... It works. It can now detect my monitor at 1080p. I just shut down and switch it on again to make sure that it is not a fluke, it works! Fyi I just acquired another Samsung LED 27" monitor SA550 (same problem as above inititially but got it working via the above approach) Thanks alot Mac80 and really appreciate it! jJpecke

Can you hook up a monitor using hdmi?

Hi I am using a Cintiqi Display and would like to add another monitor using the other port HDMI is that possible or do I need to do something else. I just wanted another display to watch videos to learn how to do some Adobe products and thought it be easier to watch it on a monitor while I work on the products ...kind of step by step process.
thanks for any help Maggie

Not all or even many monitors have HDMI ports but it does have one yes it can be connected. You can also use a HDMI to DVI adapter, in fact Apple include such an adapter in the Mac mini box.
There is one issue you need to consider though, the Mac mini only supports a maximum resolution of 1920x1200 pixels on the HDMI port. If you monitor has a higher resolution then this may not be the best solution.
Your other alternative is to get a USB Displaylink adapter to allow connecting a monitor via USB.

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi

What's wrong with my macbook pro (15" early 2011) when i connect it with TV via hdmi

Hello Alex,
It sounds like you are getting excessive CPU usage when connecting an external display via HDMI to your computer. I would try the troubleshooting steps outlined in the article named:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Cheers,

Second monitor via hdmi causing mdp to sleep

Hi
I have a 27" dell monitor which i have been using for a year on my mac mini (2012) via the display port
I have recently added another monitor and im using the HDMI port for that one (hdmi to dvi lead), both monitors work fine BUT then my 27" dell (in the displayport) will all of a sudden go to sleep and nothing i can do will wake it - i have to actually restart and then everything is ok again (until it happens again)
the display settings are set to "never go into sleep" in the control panel and its always the display port monitor, the hdmi monitor is always fine
has anyone had a similar issue, would a usb-hdmi or usb-dvi adapter work better or should i (in theory) be able to run a monitor from the displayport and hdmi simultaniously without the displayport monitor going to sleep
this is driving me crazy!

hi cable_guy,
Welcome to Lenovo Forums!
Im sorry to hear what happend..
The HDMI will not display right away, you will have to configure the computer to make it work.
I believe you will have to blind crawl to this options.
First is to press the (Windows key plus P) to pull up the menu of external display
Things to consider:
- You should be in the desktop screen and not in the log in page
- Windows 8 and Winodws 7 have a diff interface also your keystroke may differ.
=Winodws 7
=WIndows 8
- Resolution, If you external Screen does not support the current screen resolution and refresh rate it may not work. but this rare to happen.
- One last is that you will not know if the screen will not work and how it should be troublshot because you cannot see thing on both screen.

MacBook Air no longer connecting to monitor via HDMI after recent update.

Hi all,
My MacBook air typically has no issues connecting to my external ASUS monitor via Thunderbol-HDMI port. However, after the recent Mavericks OSX update that was pushed a couple days ago, my monitor says that there is no signal. My MacBook air screen flickers slightly once connected (typical behavior, as it begins to mirror the screen on a scaled resolution shortly there after) but then nothing happens.
How can I fix this?
Thank you!

Welcome to Apple Discussions
Try System Preferences->Energy Saver:Automatic graphics switching (Deselect the checkbox).
If that doesn't work you might try changing the resolution and refresh rate for the monitor in System Preferences->Displays, or downloading an app called SwitchResX (shareware) and lowered the resolution just slightly .
One other solution if possible - restore to time before update from backup.
Added restore from backup advice

How can I Communicate With Mitsubishi plc Q series

hey, i want to communicate with mitsubishi plc q series. Do i want to use any driver for this, or i can use VISA? what is the format to communicate with that.. pls help

Do you get any error code/message back? Sounds like the Java wrappers that you made for the C dll's need to be recompiled? If the application runs in a weird way using the bus monitor.exe (\NI-CAN) would help.

How can I communicate with my PCMCIA-CAN/2 card using Java?

I need to write a Java program to send messages via CAN. The program I used with the Win NT driver of the PCMCIA-CAN/2 card worked. But I have to use Win 2000 now and the new driver nican V 1.6 doesn't work (can't send messages via CAN from my Java program). Thanks in anticipation.

How can labview communicate with barcode scanner of USB interface

I have no idea that USB barcode scanner is within USBTMC or not
and there is no information available from the BCR supplier about the communication.
Is there anyone give me suggestions?

All that you need to read the scanner is a string control - just like you were entering the code from the keyboard. Could not get any simpler.
