Portege R600-13Z - flickering picture on external monitor

Hi support them!

I own an ASUS VW224 VGA monitor and a Portege R600 13Z. Is the native resolution of 1680 x 1050 and directly on VGA cable (do not know if there is a docking station). GPU driver date is 31.03.2010 version 8.15.10.2104 (newest I think).

The problem is that the screen is blinking. The darker the area displayed the strongest flicker is perceived. It's a "horizontal flicker", like the horizontal lines are pursuing each other up and down the screen. It is very annoying.

Since the laptop screen itself or the monitor with another computer ASUS show any flickers, I think that the problem is rooted in the described configuration interaction. I can set different settings on the monitor itself. Related to the problem could be 50 and 54 of Phase clock.

Windows tells me in config monitor refresh rate is 60. However, refresh rates and clock can be set to the same without change.

The meaning of phase I don't know.
Any ideas to solve the problem?

See you soon!

I think that it comes to the grounding of s.
Please check if the flicker would be available using the battery power.

I've been reading about such symptoms on external monitors.
In most cases the use of the power supply cable 3 cord would solve this problem.

  • Portege R600 - how to use the external monitor on the docking automatically

    Hi - I just got a new Portege; R600-102. It's a great machine - very light and fast.

    I connect to a Slim port replicator to the office and I wish I could anchor and automatically use the external monitor without opening the laptop. Can someone point me in the right direction on how to do it? This process has worked well on my recently retired Dell X 300.

    More precisely:
    # I have the laptop closed Portégé and standby mode
    # I anchor in the Slim Port Replicator (SPR)
    # I press the button 'on' on the SPR
    # I see the message "recovery windows" and the bars of the countdown on the external monitor. (So I know it's connected and you can see the external monitor)
    # The laptop turns on but use the laptop screen (private) LCD
    # I have to open it and manually tell it 'out to watch.
    What can be automatically?

    Thanks for the tips.

  • Portege R600-13Z - Toshiba utility SMS - slow / stop when the SIM is in!

    Hello

    Portege R600-13Z running XP Pro.

    Recently updated the firmware and the Wireless Manager to try to get 3g / GPRS comms to work at all. Updated worked a treat and have now great comms.

    Utility of SMS does not work too well if. Very, very slow or crashes.

    Wierdness: out the SIM card to use the phone to send a few texts and with the SIM on SMS utility works very well (!) starts, allows composition, everything except the real /sending/ of the text, which is of course not possible because the SIM card is somewhere else.

    Anyone encountered this problem, and is there a solution?

    Thank you very much

    > took out the SIM card to use the phone to send a few texts and with the card SIM SMS utility works great
    If you noticed delays in using DMD utility only with the inserted SIM card?

    Hmm I m not very well why this happens, but I know it s not recommended to insert the SIM card if the system is already running.
    You must shut down the laptop, must insert the SIM card and then you should power the device in place.
    Then you could test this once more.

    Hello

    I put t know the part number, but as far as I know that you need a * 12.1 WXGA (1280 x 800) widescreen mast *.
    Generally any Widescreen Matte 12.1 WXGA (1280 x 800) should be compatible with Portege R600.

  • Qosmio X 500 - 13R: picture on external monitor with resolution 2560 x 1440 is blurred

    Hi all

    I have a computer laptop X 500 - 13R Toshiba Qosmio, although 2 years, still a great piece of hardware.

    I just bought a new monitor 27 "U2713HM which supports a resolution of 2560 x 1440.

    Computer video card notebook (GTX 460 m) supports a resolution higher than through a digital connection, so I used a HDMI cable to connect.

    Via Control Panel Nvidia, I could create a custom resolution, but the image is not clear / is blurred.
    It is readable, but it's just not everything.

    Tried with HDMI 1.4, without success.
    I volunteered to connect through Dual Link DVI cable, but the phone doesn't have a DVI connector, and I doubt the adapter will help.

    Anyone has a suggestion how to fix this problem?

    Thank you.

    I would like to share my experience using an external monitor with a HDMI cable.
    My monitor supports both HDMI and DVI port.
    First of all, I plugged my laptop on the external monitor using a HDMI cable to HDMI.
    But the fonts and the picture was not clear. I used the resolution 1920 x 1080

    Then I went to the DVI port. I plugged the laptop s HDMI port to monitor s port DVI (HDMI/DVI cable) and that solved my problem.

    I'm not quite sure the relevance of m this could be for you, but it worth the try

    Hello

    How have you tried to exit from display on an external monitor?
    Usually, you use the FN + F5 key combination.
    This allows you to switch between the two screens; laptop + external display.

    I had a problem to view a video on the external monitor because the video is already running. You must switch to the external display until you start the movie, etc.

    It is impossible to detail more that I thought that the language is inappropriate, but everything I am captures the messages displayed by the laptop

    Hope it works at first

    Hello

    The laptop supports a simple slot ExpressCard.
    Usually, you should get an ExpressCard compatible all work.
    But I ve never used the NetStor Turbobox, so I can't say exactly if its compatible or not with this ExpressCard slot.

    Have you checked the page of the manufacturer of the NetStor Turbobox support?
    Maybe you'll get more details on this unit that maybe some special requirements are needed to use this

    Please post some info so you'll get some.

  • Horizontal flickering ghostly on external monitor?

    I have a HP Pavilion dv6654us notebook PC, which has an Intel GM965 chipset with integrated graphics X 3100.  Connection to an external monitor gives a horizontal flicker.  It's barely noticeable on white, but very noticeable everywhere else.  It also seems to degrade the color of my images.  I checked the VGA port on the side of my laptop, and it is clear and without any obstruction.

    I am currently using Windows 7 Ultimate, but this same question occurred on each operating system that I have used this monitor on this laptop, including several distributions of Linux and Windows Vista.  I currently have the latest version of the BIOS, however, it has occurred in each version, I've tried.  All operating systems are the latest available Intel video drivers.

    The monitor is an Acer X223W.    This monitor is not the issue, as I have the mid-tier business computer laptop Dell with a GM945 from Intel that does not cause this problem at all.  On my HP, the problem occurs on the external monitor at all resolutions.  Changing the mode on my Intel video has also no effect, this problem occurred as well in extended mode and when it shows only on the external monitor.  It does not, however, affect the LCD screen of my laptop or any non - LCD external monitors such as projectors.

    I want to check on what think about this on the forums before involved me in the - what you must admit - horrible support HP offer process.

    I suspect that you have a ground loop problem. Ive seen on many laptops over the years and not isolated to just HP. Your monitor probably has one to three pins taken and then motive. Your portable computers adapter likely has a PIN of three institutions and began to land. But your laptop computer likely (as you can see on the cable that goes from the adapter to the laptop) did NOT have a motive. You end up with a ground loop in the monitor and therefore noise.

    The only solution I have found is I took a spare power cable and removed the PIN to the ground for the monitor. You can simply use an adaptor which only has 2 pins but accepts three. The later version Id suggest trying. Worst case your outputs 50 cents.

    Now, keep in mind that the ground is there to protect you in force. ID never suggest to do this but I can almost garauntee it is your problem. I guess that the engineers did not design laptops with the ground because they are such low voltage. Nevertheless, it is a bad idea and in my humble OPINION evil genius. They should have a reason for scenerios just like that.

    I'd like to note this is not the fault of monitors. Ive seen with dozens of lcd and crt monitors. Its the fact that the laptop has no grounds.

  • Satellite Pro P100: losing picture on external monitor when using the DVI - D connection

    Guys,

    I have a Samsung SyncMaster 940MW LCD TV and a Satellite Pro P100 (Geforce Go 7600), recently I bought a DVI - D cable to link them together.

    Now the problem is that when I connected to 1400 x 900 LCD TV screen goes to a black screen several times (usually when there is a lot of activity or I'm resizing windows to the maximum to the minimum).

    Now, I would have thought it would be the LCD TV doesn't do not signal or refresh rate however I connected using a VGA cable and its fine - no problem just no matter how much I minimize my windows or put a lot of activity on the screen. To complicate matters even more, when I run the screens in "Dual screen" mode instead of "Clone" if I put one of them 1400 x 900 to 59hz in 16 bit it works fine...?

    Can someone help please that it made my head that I can't understand what the hell is the cause!

    I've included a list below all the different resolutions / screen modes I tried it and the result.

    Thanks for your time & help.

    Hello

    I hope that you have enabled user s manual supplied with your device. On page 148, you will find a very interesting picture on the supported display resolution.

    I have to be honest with you and say that I am no expert DVI because my LCD doesn't have this port, just HDMI but if I have understood you as soon as you have problem with a resolution of 1440 x 900 only. This resolution is not listed as supported, and I presume that it is not unusual to have a problem.

    Sorry, but I think that you should use maximum supported only resolution 1280 x 1024.

  • Portege M800: No image on the external monitor

    Hello
    Today, I tried to connect my PC laptop Toshiba M800 to another CRT monitor without success.

    I use the Fn + F5 keys, but nothing happens, I mean a small window opens which shows me the options LCD, LCD + CRT, CRT, LCD + TV etc, but nothing happens when I choose CRT or LCD + CRT.
    I use a VGA cable, it's ok because the same monitor and the same cable works fine when I use my Acer laptop.

    I even downloaded the latest display driver Intel and the last updated of the BIOS, but there still nothing...
    All ideas will be welcome. :)

    It's very strange.

  • External monitor flickering Macbook 2016

    I have a Macbook 2016 and an Apple USB - C for Multi AV-HDMI adapter and a LogiLink USB - C for adpater DisplayPort.

    I am using a Dell 3008WFP as an external display monitor (maximum resolution 2560 x 1600 @60 Hz) with my MacBook, but it doesn't seem to work well.

    The monitor will often empty after a short time ('economy' mode) or only occasionally displays a picture and then turns off again. Using a LogiLink USB - C for Displayport is a bit more stable then the adapter Apple, but also often suffers the same problem.

    On a small monitor Samsung 1920 x 1080, the Apple Multi AV adapter seems to work perfectly well, but on the Dell, it is not stable (via HDMI to a resolution of 1920 x 1200, as the Dell only supports supported resolutions higher on DVI or DisplayPort).

    The map is updated latest firmware 2.33. Is there a problem with my MacBook (again)? Or is it a software problem? Is there a work around? Does anyone have a good experience with the MacBook to 2560x1600@60Hz on an external display?

    Hello Schendstok,

  • What is the largest external monitor I can use with Portege M400?

    I have a Portege M400-s5032x tablet and a pa3680u docking station. I would get a larger external monitor for use with the docking station, which is the largest monitor I can use?

    I have a widescreen 18.5 on there now and that you would go up to 20 or 22 inch widescreen.

    As far as I know that there is no limitation. You can use what you want.
    The only thing that may be problematic is the resolution of the screen.

  • Portege M800-106 - bad quality by using the external monitor

    I use an external monitor LG Flatron L1811S on my Portege M800 and find that the image is not rock solid when I use the display on my desktop or screen of the M800.
    It is particularly visible on the big patches of color block where I can see shimmering light. I noticed that it's especially bad if I recently reconnected the laptop to the network after using on battery power until the battery is fully charged.

    This makes me think that the PSU interferes with the VGA output?
    Any ideas?

    Thank you

    To be honest I m more important lack of information in your ad.
    Are you using the native resolution - 1280 x 1024 / 75 Hz on screen?

  • Portege M800 - horizontal lines on external monitor

    I just bought a number of new M800 (model number - PPM81A-06L01J) and all have second screens connected.

    On all secondary monitors, there are wavy horizontal lines. Secondary monitors are all of different sizes and different brand and model. They are all also on their native resolution and refresh rate. I also got the latest video drivers installed. Any body have an idea as to why this is and how to fix it?

    See you soon

    Brad

    Hello!

    I n t have a Portege M800, but on my Portege M700 I had some problems with the external monitor connected too.
    Here's the story about this:

    I connected the new external monitor for Portege M700 directly with an old VGA cable. Usually it t wasn't a problem for me but I was not satisfied with the quality of the image on the external monitor (a bit blurry) so I started to update the display driver and the BIOS of my Portege M700 but without success.
    Anyway, I tried a bit with Google and here in the forum and I decided to buy a new high-quality VGA cable. I exchanged the cable and what happens? Perfect image quality!

    As you can see, you should always use high quality new cables. Also, make sure that you use the highest screen resolution of the external display (native screen resolution) and set the refresh rate of the screen at 60 Hz.

    Good bye

  • Portege M400: Is it possible to use the resolution 1400 x 1050 on external monitor?

    The Portege M400 SXVGA (i.e. 1400 x 1050) can support 1400 x 1050 via analog / external monitor? I ask this question because I can't do! Most importantly, he is happy to provide, even if the monitor is a TFT 1400 x 1050 screen is 1280 x 1024.

    I downloaded the latest Intel drivers and screen drivers, and although the o/s reports screen as being happy to show 1400 x 1024, it is not an option when selecting the resolutions.

    Is this a known issue?
    It is corrected using digital?
    Am I stupid?

    Hello

    I'm not 100% sure but I think that that it will not support a higher resolution. In my opinion, it is according to the performance of the graphics card and the resolutions supported and not according to the used port.
