Satellite L850-1V5 AMD RADEON HD M 7670 - no display on external monitor

Hello.

I'm having a strange problem with my Satellite L850-1V5 new with card in order to 7670M AMD RADEON HD.
(It runs windows 8 64-bit family)

At the beginning I couldn't open the CCC.
So I uninstalled the program and reinstalled the drivers I found here, on the Web at Toshiba Europe site.
Now it works well.
But now I have another problem.

First, I tried to extend/duplicate(whatever, it does not really matter) my workstation via the VGA port.
In CTC, I could see that he acknowledged my external monitor model and even the mouse cursor has acted as the Office has been extended.

BUT
1. it has no image on the external monitor
2. on the input of the external display Menu(:where one chooses the port to be used, i.e. VGA, HDMI, SCART, DVI etc etc) VGA port c o u l d NOT be selected, as if there were no cable on the external monitor

Then I tried an HDMI cable with the same result, with the difference that on the external screen menu entry the HDMI port c o u l d be selected, as if it were a cable on the external monitor, but the monitor says "no signal".

I tried the same steps via Windows Control Panel (menu Display).

Same results...

I tried on 2 different external monitors (the two LG ones, even if we're about 3 years older than the other, so I guess he should have nothing to do with the monitor).

Any ideas?
Is this a hardware problem, a software problem? Toshiba Service go?

Hello

To my knowledge, use the keyboard shortcut to switch to an external monitor.
AFAIK the F4 (or Fn + F4) changes the output display.

Have you tried using this button?

  • AMD Radeon HD M 7670

    I'm looking to replace our computer laptop, mainly used for travel, with one that is good for CS6 applications but very big in screen size not too heavy, that is not a cell phone game. For Photoshop and many other applications the Ivy Bridge CS6 currently advertised systems seems worth waiting for.

    If possible, I would a cell phone that also supports use of Premiere Pro (limited by the small screen, probably only a single disc etc.). I've seen the specification of the Sony Vaio Z with integrated HD Graphics 4000 2012. A Port Replicator / Docking Station contains the AMD Radeon HD M 7670.

    Does anyone know if this card or will in the future provide acceleration GPU/Mercury for CS6 Premiere Pro?

    It is not possible to activate the acceleration on this GPU with CS6.

  • Re: Satellite C855-155 - AMD Radeon HD 7610 display driver does not work

    Hello

    My laptop Toshiba Satellite C855-155 2 years, used to run the display driver AMD Radeon HD 7610 (V8.932.5.3000 January 20, 2012). Suddenly, it no longer works. Login screen looks scrambled. I can only start the laptop with the Standard VGA driver but the screen resolution is 1024 x 768 (not the 1366 x 768 normal) and no screen dimming, automatic off tension or sleep/hibernate functions is not working either.

    What do you recommend? Is it a hardware failure?
    Thank you in advance,

    Hello

    Have you tried to reinstall the display driver?

    Best test you can do is to back up all your important data and reinstall original recovery image and test your machine with the factory settings. If the problem persists it may be hardware related issue.

  • Satellite P300 - randomly turns off the power when connected to the external monitor

    Hello

    I have a Satellite P300, Intel Core 2 Duo T9400 2.53 GHz, 4 GB RAM, ATI Mobility Radeon HD 3650 512 MB, running Windows 7 ultimate x 64.

    Recently, I bought an AOC v22 led screen and connect my conputer via HDMI. Everything works fine, but sometimes my computer off just randomly. I might have something to do with my computer overheating, so I clean the fan, but this was not good.

    I think it has something to do with the LED screen because my computer was never off his own.

    Hello

    So this also happens if you n t connect laptop to external display? So, you can determine what is causing this problem.

    If the computer laptop doesn t turn off without external monitor, you should try to update the BIOS and the display driver. Two updates that you can find on the Toshiba site:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

    You close the lid if you have connected the external monitor?
    What operating system do you use?

    In addition, it would be interesting to know how you clean the laptop. That's why I use the jet of compressed air that can blow the dust from the cooling fans and you don't have to disassemble the laptop.

    Good bye

  • Satellite A200-1BJ - no display on external monitor

    Hello

    I have a display problem with my laptop, which is:

    When I connect my computer to an external display (projector - data show - using the rgb or s-video cable), the contents of my computer are not displayed.
    I used F5, Catalyst Control Center, but without success.
    When I connect it with a TV using s-video, I get the message "no signal".
    I think of the existence of the other devices, but the content is not sent to the external display.

    I don't know what the problem is. I need to use my computer and the screen using a projector for my presentations, which is very common.
    The problem is that he used to work, then suddenly it stopped display on external displays.
    I could not understand the problem, then I thought that the settings have been changed accidentally.
    So I formatted my computer back to the factory setting, but my attempt failed and it still does not display on the external monitor.

    My computer specs:
    -Toshiba Satellite A200-1BJ
    -Processor: Intel Core2 Duo
    -OS: Windows Vista editions Home Premium
    -Graphics card: ATI Mobility Radeon HD 2600

    Does anyone know the solution?

    Thanks in advance.

    In your case I would update the BIOS and the display driver. The two you can find on the Toshiba site:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

    Have you tried different cables? Maybe it s faulty or too long.

    Also, be sure to use a rate of resolution and refresh supported for the external monitor display. You can change that in Catalyst Control Center.

    Try to uninstall the ATI graphics card driver which is pre-installed on your device.

    Then, visit the Toshiba UE driver page and download the latest driver available GPU ATI/AMD.

    Once installation is complete, reboot the laptop and check the functionality.

    Hello

    It is both the latest drivers available from Toshiba specifically for your machine...

    I think the Win 8 2012, and pilots Win 8.1 are 2013...

    I'm sure there are newer drivers, but which are not compatible with your machine...

    Type M chips and drivers are different from those of a desktop machine where it is not really important who built the computer because the driver and catalyst for the chip...

    Laptops are different, because manufacturers sometimes customize drivers to their specific models.

    That's why you have problems. You posted a list previously of three manufacturers which are not compatible with the AMD drivers, one of them being Toshiba...

    That's because Toshiba has changed the drivers or the material in such a way that the normal drivers do not work...

    You can try to update the drivers for the newer versions through windows or Windows Updates... you might get lucky and they will work OK or maybe even better...

    There have been problems with graphs of type AMD M since Win 8 came out, so I can't say with certainty what will happen.

    Drivers AMD come as a complete package now... CCC and all drivers. They tend to be available separately, but may not be. I saw a couple of times where you can just get CCC, but it's very rare...

    Sometimes you will get just the driver of Windows updates even if...

    Just bought a computer laptop g6-2235tx and took a glance at Windows 8 and decided to format the hard drive and reinstall Windows 7 Ultimate 64 bit.  Went to the site of HP and downloaded the drivers and they wouldn't install.  No problem, I'll use Google to find... after a lot of googling and downloading different packs pilot from various sources, I still can't install the 7670M Radeon HD driver and activate the hardware accelerated graphics.

  • Re: Satellite A100-283 - 16:9 display on external monitor resolution

    Hello

    I just got an old Toshiba Satellite A100-283 and tried to connect it to a TFT 22 ". Somehow, it seems that this laptop graphics card does not support the external screen such as 1920 x 1080 resolutions. I find 16:9 1920 x 1440 resolutions and such but not at all.
    Is - anyone here know if there is a way to get this notebook running on an external display in 16:9?

    Thank you in advance for your help!

    Hey Buddy,

    You can change the screen resolution to the 16:9 format when you remove the brand to hide modes that this monitor cannot display as [THIS | http://blog.wildvista.com/wp-content/uploads/2009/12/Lightroom_hide_modes-340x400.png] photo?

  • Re: Satellite Pro U400-130 poor quality display on external monitor

    Hello

    If I connect an external monitor to the display quality VGA port is quite poor. It looks like a 'grainy twinkle"(sorry hard to describe). I have tried several different monitors and made all the adjustments that I can find. If I increase the contrast to max is not visible, but still the screen is too bright. The internal TFT is perfect.

    Have you tried to change the display settings on monitor itself (brightness)?

    I have connected to my office two different external screens (19 and 22) to U400, and the image is OK. I really don't understand what makes you so unhappy.

  • Satellite Pro 4030 boots with white screen - works OK on an external monitor

    My sat 4030 pro, Vibrio W98SE, boots to a white screen. When I press the lid closer, or use Fn/F5 it turns black. It works fine on an external monitor.

    Hi Robert,.

    If your screen is displayed correctly on an external monitor, then it indicates that your chip graohics still work correctly, then you the problem must be with the LCD itself, the FL inverter or the connecting cable to the main Board. I would recommend that you contact an authorized Service partner who can perform other tests to diagnose the fault.

  • Update drivers Catalyst for Satellite L850-150

    Hello

    I bought a Toshiba Satellite L850-150 (AMD Radeon HD M 7670) 3 days and I don't know if getting angry with AMD to restrict their pilots or Toshiba do not update their own pilots.

    Can you give me a technical reason for the manufacture of incompatible laptop with AMD generic drivers?

    I got an AMD Radeon HD M 7670 an AMD Radeon HD 7670 M in a Toshiba, in an ASUS, Acer, etc. If you make your laptop incompatible with other drivers, at least, maintain your own drivers updated.

    On this forum and also checking many other forums you will find hundreds of threads with the same question over and over again.
    It is well known that manufacturers of graphics don t mobile support units and this support is for manufacturers of laptop only.

    Technical reason?
    Can imagine you that you want to have more graphic and more performance by using more recent driver. One day you feel burnt graphics card. What do you think should be responsible for this and who should pay for the replacement of the motherboard?

    The problem is, I'm not able to install the AMD display driver. When I try to install the software and drivers this problem appears: https://youtu.be/AOiPq8WVz_M

    The first time that I was using Win 10. I did the update to win 10 about a month ago and everything was ok until 4 days ago. I was working with my laptop with an external screen connected by HDMI and all of a sudden the screen started to Flash some green lines with a black background (something like you can see in the video).

    I saw on the internet that some people have problems making the update to wion10, I have installed new Windows 8 to see if has something related to win10 but the problem persists.

    I tried to install the intel CPU, a graphics 4000HD Intel GPU, but may not use it as a main GPU. I had this problem: "this device does not work properly because Windows cannot load the drivers required for this device. (Code 31) »

    Hello:

    I think I finally found a driver that works.

    None of the other drivers that we tried was the hardware ID for the GPU to your laptop, but this one doesn't.

    This package provides the AMD graphics driver high definition (HD) and Catalyst Control Center for models of laptop computers that are running an operating system supported. For laptops equipped with switchable graphics modes, this package contains the drivers for the two graphics (GPU). Switchable graphics allow users to switch between a graphical power mode (normally used under the power of the battery) and a mode of graphics performance. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

    File name: sp69161.exe

    You may need to install the driver manually if auto installation does not work.
