VGA port problems

I use an external monitor when in my office with my N100, and for some reason I think the VGA port has gone bad. I have tried using various monitors and projectors and there seems to be no signal output from the port.
Does anyonehave any trouble shooting ideas before I have to replace the whole board?
Thanks

Dear Sir,
My suggestion as bellow :
1...Please check your driver status by using system device manager, make sure no corruption or error of display driver.
2...Check the display property, which the 2nd monitor/display setting solution is correctly suite your display monitor/project. you make disable/turn off the attached monitor and re-attached to double confirm your resulution to second display is correctly install. right click the monitor on 2 display monitor on display properties disattached and reattached.
3... U may also try to clone your display,, clone monitor mean, same as 1 and 2 display.
Usually vga port will not bad if you not sock it by high power electric device.
I suggest u, for testing/troubleshoot purpose, plug-in your 2nd monitor/project than u start your system to make sure 2nd monitor/project also detected.

VGA Port problem !!!!! No Post ?????

Does anyone have any idea what could be causing the following :
When I hook up the board with the CPU and stuff, with the Graphics card plugged in, the MB will power on for like about 0.5 of a second and then go off.
If I take the VGA card out, its runs fine.
The MB is brand new , never used........
The card is an AOpen Aelous GForce4 Ti 4200 8x
RAM is Kingston RAM 400Mhz CL3 2.5v
CPU XP64 3200+
MB: K8N Neo Platinum
I have tried other RAMS with a lower speed. But its the same all the time.
Thanx alot
Pete

What are the PSU specs?
Could be faulty card or AGP slot, it it OK with another card.

Problem with VGA port of IdeaPad G580

Hello all,
I am trying to connect my analogue VGA Samsung display to my new IdeaPad, just as I did with my 5 year old Sony Vaio. The problem is that the standard cable won't fit into the in-built VGA of the IdeaPad. I understand there are other possibilities (i.e. using a DisplayPort to VGA), but I don't see a reason to do it since the VGA to VGA port is the simplest cost-effective solution for me.
Has anyone had this problem? Is it possible that my IdeaPad is badly assembled and will therefore not accept a normal VGA connector?
Thank you for your help.

Hi Gamoreno,
Welcome and Thanks for posting in the Lenovo Community,
I’d like to ask you to explain more about the issue and could you please share with us a picture from your VGA Cable that you are trying to connect.
Thanks and Best Regards,
Soha

I need to install the HP drivers on a laptop with a broken screen in order to get VGA port to work.

OS: Windows 7 Home Premium SP1
Hewlett Packard Model: 2000 2a20ca Notebook
Oh my god please give me some insight here, it is so hard to find the right answers and I refuse to lose to this technical box that's driving me nuts! So here's the run down:
My screen broke on laptop...fine. It was connected via HDMI to TV and working fine. Until one day it decided to not turn on. I think due to Windows updates and hubby had no patience so kept restarting
I tried to reload Windows on it, not thinking about the drivers, and I'm pretty sure I managed to reload Windows. Now I need the drivers to install chipset, networking etc. (which I have a disc for)
The problem is I cannot see the screen in order to click "install", I can't see the BIOS or the boot sequence. Ugh! And even if I could, the drivers are not installed to use the CD ROM or VGA port.
I can HEAR Windows start up and turn on! Doo-DO-Doo-DO lol the darn thing is working!
The monitor works in my other laptop.
Would/Should the VGA monitor work if I could get it to start in safe mode?
I've heard of a program that can streamline the driver's into a Windows installation disc so everything is installed altogether but how can I reinstall Windows if the drivers aren't loaded for the CD ROM?
Is there a way to get the necessary drivers installed? or is this notebook now garbage?

1. The model number is the first thing at the top aside from the OS.
2. In my explanation it states: "I have the drivers on a disk"
Thanks for all your help!
Getting the drivers is not the problem. Getting the drivers installed on a laptop with a broken screen...is the problem.
Ok, well sometimes you can't use external monitor to see what is happening in some laptops and the only real way to fix this is to fix the broken screen so you can reformat and resinstall the system again. Those are you only options at this point in time.

Satellite P750 - Unable to connect external screen via VGA port

Hello All,
My problem is following:
I have been trying to connect my P750 (running on W7 x-64) to an external screen using the VGA port/cable. Unfortunately the external devices does not recognize my laptop. Laptop does recognise the external screen, you can see it in the graphic settings as additional display, but the screen says "no signal".
The computer always identifies the screen correctly, so it looks like there is communication from the screen to the PC, but not the other way round.
This has been checked with 3 separate screens and a TV - always the same. All the screens work properly with different PC's.
I already did:
- try to play with FN+F5 / "windows"+P buttons - no change
- install the latest BIOS and Video drivers from Toshiba website - no change
Any suggestions how to make it work? Is it possible that the VGA port is faulty?
Thank you in advance.

Hello and thank you for the tips,
I did try the options you suggested unfortunately with no success.
I actually got myself HDMI cable and this connection is working perfectly well. Luckily the very screen I want to attach my laptop to does have HDMI port. It is just a bit annoying to know that the d-sub port seems to be useless.
The lady from Toshiba tech support call centre suggested either OS re-install or sending it to Toshiba for repair/check as it is still under warranty. None of this options suites me at the moment, so I will probably stick to the HDMI. Still, I have a feeling it is a software rather than hardware problem.
Cheers

T420s Linux and the DVI+VGA port

Hi,
I currently have some problems with my graphic ports of my new ThinkPad T420s (4173-W1J). My problem is a bit complicate (I think) but I will do my best to explain it very detailed. Sorry in advance for any stupid mistakes I made with my configuration.
Problem 1:
I have ordered the notebook with the Intel graphic card, not the NVIDIA one. What I do not understand - If I look in the BIOS of the notebook, I find something with "OPTIMUS", what indicates to me that there is the NVIDIA card inside. Also, if I call "lspci" using my Linux (Kubuntu 11.04) system, I get the following TWO graphic cards:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 1056 (rev a1)
running "lsmod", I get the following output (only relevant video modules, as I identify them to be relevant):
uvcvideo 72195 0
videodev 82052 1 uvcvideo
nvidia 10709116 0
nvram 14419 1 thinkpad_acpi
i915 515121 2 video 19438 1 i915
So I thought - "hey, maybe they made a mistake during configuration and send me the more expensive NVIDIA card included", so I tried to install the nvidia drivers "apt-get install nvidia-current nvidia-settings", but after this my KDE (x-server) does not boot up anymore. After removing the nvidia packages, X-Server booted up again without any problems. How can I find out either of the NVIDIA card is REALLY included, or only the Intel HD? If the NVIDIA is included, what do I have to take care about to enable the correct nvidia drivers?
Problem 2: The main reason why I came to problem 1 was, that I did not get the DVI port of my attached docking station to work. On the one hand, the VGA port works fine, on the other hand every time I attach the notebook to the docking station, I always have to reconfigure the screen resolution and position manually. Even if I say "save as default", he somehow forgets this configuration every time. Also, sometimes the VGA screen does not work, even if I use the same configuration like ever -- I then have to "exchange" the "left of, right of, clone, ..." a few times and it starts working.
For sure, no cable, monitor or whatever is broken - since e.g., I am using the internal and external monitor at the same time right now (in 2-monitor-mode).
So I wanted to solve this issue by using the DVI port - but this port does not work at all (at least I do not know how to enable it!). Using google I found out, that if the NVIDIA card is inside, and the "OPTIMUS"-"feature" is used, than one needs to use the NVIDIA card, otherwise the DVI port does not work. Sadly, as discribed in problem 1, I am neither sure if I have the NVIDIA card inside, nor know how to enable the DVI port at all.
Any help would be very appreciated. Thank you in advance.

Hi,
after I've forced the BIOS to use only the discrete graphic, I now have additional problems.
First, my system hangs every 2nd time before I even see the grub menu (which runs in graphic mode, thus the screen is blue). If it freezes, I only see a blue screen. If not, I see the blue screen with the normal grub menu. This seems to happen every 2nd boot-up.
A similar issue I had before, since I use full-disc-encryption and grub was unable to load the fonts from my hard-disc, so I copies all grub fonts to the boot partition (what is of course not encrypted).
Second problem, I've installed the NVIDIA drivers you suggested, worked without any problem. After restart, KDE showed the nvidia-logo correctly. But after the login, KDE initialises the user-settings, and there he again freezes my system completely (at about 2/3 of the user-settings-initialisation).
To be honest, I do not know how to proceed. :-(

Quality issues with VGA port on Type 2504 docking station

Hi,
I see quality issues on the VGA output of the Type 2504 docking station with a T61. The monitor image is blurred, not much, but enough to be irritating. When I compare the DVI output with the VGA output on two equal NEC MultiSync LCD 2170NX monitors it is a clear difference. If I connect the LCD monitor to the VGA output of the T61 itself, the picture is clean. I have tried both monitors with different cables in different configurations and also adjusted monitors manually, and my conclusion is that it must be the VGA output of the 2504 that generates the un-sharpness. I have got several 2504 docking stations from the IT department to test and all attempts show the same unsharp picture on the LCD connected to the VGA port of any 2504. Recently a colleague got a new laptop and docking station. He also used DVI and VGA on the old setup and had no visible difference between the two monitors. His new setup is a different T but his new dock is also a 2504. Now he has clear difference between his monitors. He also tried several 2540 docks and cables but the difference is still present.
The unsharpness is not immediately present when just looking at a dual head setup. But after a while it becomes tiresome to look at text, specially black on white, on the monitor connected to the VGA port. There is a slight shadow on the right side of all letters. When looking at non-aliased fonts, they look as if aliased on the VGA connected monitor. Already aliased fonts tend to "smear" and I have the unpleasant feeling that my eyes are not focusing correctly.
My question is: Is there a different VGA DAC on the docking station, or are the analog signals just wired through from the laptop VGA DAC? Older IBM docks do not have this problem, we have a lot of them at work in dual head configuration with DVI + VGA to compare, and we only see this problem with the 2504.

VGA is an analogue signal... so it can be affected by the quality of DAC chip used by the GPU associated electronics, the quality of connectors on the vga out and dock (that is why good analgoue audio equipment use gold plated stuffs) and the quality of copper wire and shiedling used in the cable (i.e. Low Oxygen Content Copper wire).
The above is general description for all people to use <---- so please don't feel offended if i repeat something that is already said.
There is NO conversion electronics on the dock per se, they are just passthrough, so no conversion.
I guess the problem lies with improper shielding somewhere. I have the same problem with my T61/60 and dock and my T40,41,42,43 on five different docks.
So i have ended up using lenovo usb2dvi converter on T61 and have two dvi output and bypassed the vga altogether.

Can I connect my older ti powerbook with vga port to my adc cinema display?

can't seem to find an adapter...does it exist?

They exist but are very expensive. The problem is that the ADC connector also supplies power to the monitor, and your VGA port has no power. The device you need is a box that plugs into the wall and to the VGA on your powerbook. These are combined and sent through an ADC line.
like this one priced at almost $300

TV LCD JVC LT42x50: MACs cannot use the VGA port!

I have a MacMini 1,5 core solo and tried to connect to my TV via VGA (as I used to do with my old PC notebook).
I wish I read the TV istructions before..., but it clearly says that his VGA port it's not for Macs!
Ihe qustion is: is there a way to modify the MAcMini output so that my TV can get it?
(I asked the MACshop guys here in Rome about this problem but they couldn't find an anwer...)

Like Boece, I don't have any personal experience with SwitchResX since my minis all run with commonplace displays or TVs which they drive at nominal and default resolutions. But if SRX doesn't offer an option to save the settings you have manually set, it suggests the system should correctly save them for reuse in the property list file.
However, it is also possible that the TV, since it's connected by VGA (rather than using a composite adapter) is feeding the mini with an ID signal which overrides your SRX settings. Since MacOS uses the ID data from displays to create 'correct' settings for them, that could potentially explain why the settings you give it are not working.
Also worth noting is that you may be selecting modes which are NTSC rather than PAL, so if the display is giving you options, ensure one matching the PAL standard is selected.
In this situation, if you are not able to get assistance with someone familiar with SwitchResX, and resolve it that way, if your TV has composite input (a yellow video input with red and white for stereo audio) I'd be inclined to suggest you try Apple's DVI to Composite/S-video adapter and connect up that way. It has not failed in any situation I have tried, at least at 640x480 or 800x600.

VGA port loose

I regularly connect a 2nd monitor to my laptop through the VGA port. Recently I have been having issues with it and the wire staying in properly. I had been able to prop it up a little, but that now is not even working and not that practical all the time.
It appears that the actual port on the laptop is loose. I even just bought a new wire.
What can I do about this?
Thanks a lot

On further investigation, I have realised that the client meeting rooms in which I have a problem have two NEC plasma displays side by side so you can select a number of options - having a conference with two sets of remote attendees, or the same presentation displayed on both screens, or just the one screen. The same NEC plasma display is used on its own in other client meeting rooms in which there is no problem at all - so clearly it is an inoimpatibility with the mini-display-port-to-VGA adapter and whatever technology is used to display to two external screens instead of just the one. The in-room system is set to display to just the one screen and, like I said above, Windoze machines just work with it.
Is there an update I can apply, or a setting I can change, which will solve this issue for me? Honestly, I'd rather not carry another Windoze laptop around with me as the MBP is heavy enough, and of course all my business software is on there too so I'd then have to duplicate all my office software as well at additional cost....
Tks

VGA Port

I have an older Macbook, one of the white ones. I use it in my classroom with a projector. When I connected the VGA adaptor yesterday, it would not work, the image that it projected was just a purple screen. I know its not the projector, or the VGA adaptor, because I checked them with another cokmputer. Any ideas on how to solve this problem?

Dear Sir,
My suggestion as bellow :
1...Please check your driver status by using system device manager, make sure no corruption or error of display driver.
2...Check the display property, which the 2nd monitor/display setting solution is correctly suite your display monitor/project. you make disable/turn off the attached monitor and re-attached to double confirm your resulution to second display is correctly install. right click the monitor on 2 display monitor on display properties disattached and reattached.

X230i VGA port while docked

Hi,
I was wondering if anyone can help me with a problem I'm having.
I have a Thinkpad X230i laptop which is used in a docking station. The monitor is plugged into the docking station using the VGA port. There seems to be a slight issue with the laptop's port that allows it to dock that is causing wavy lines to appear on the monitor. I've tried a different monitor, different cable and different docking station and it's definately that. There is a vga port on the side of the laptop, when the laptop is undocked I can use that port to connect the monitor and the picture is clear and there's no wany lines.
My problem is as soon as the laptop is back in the dock that port seems to become unavailable, the monitor is still plugged into it but it just won't display onto it. I've tried various different detecting of monitor and screen settings but I can't seem to get it to use that vga port instead of the one in the dock. Does anyone know a way to get it to use the laptop's internal vga port when docked? Any help would be much appreciated.
Thanks,

try downloading the latest Omega Catalyst driver from the web.
If the vga port don't work, you can always get a Lenovo usb2dvi port to get an additional dvi port from your usb, or a dock (if portability is not a problem) which has a vga + dvi port.

Satellite L645D-S4030 second USB port problem

Hi, I'm having trouble with the second USB port that's connected with the VGA port on my Satellite. I try to use my external hard drive, flash drive, and wireless mouse receiver on this port, but I've noticed that when the external hard drive is plugged in the light flashes on for only a second or two and the port itself never recognizes anything plugged in.
Can anyone help me figure this out? I've looked everywhere for a topic covering this problem and have turned up nothing

I am attempting to resolve a similar problem on a friend's L655. Except that no USB device connected to any of the USB ports are recognized. I do have an unknown device in Device Manager in the USB Controllers section that I have been unable to resolve.
You may just need the driver installed. Have you tried that?.

Adapter for vga port

I have an HP ProBook (don't know where to find the model number). It has a 9 pin male VGA port. My VGA cables are 15 pin male. What adapter will allow me to connect the cable to the port, just like I was connecting to a 15 pin female port? I tried a generic adapter that allowed me to make the connection, but nothing came through the cable to the TV I connected the other end of the VGA cable to, so just any adapter that allows the connection doesn't necessarily work. It apparently has to the right one for this PC.I said the operating system is Windows 7 (64 bit), but it might be 32 bit. I really don't know how to tell which it is. Does that make a difference for what adapter will work for the VGA port?

Without the model number it is pretty hard for us to help much. A 9 pin VGA port is analog and a 15 pin is DVI or digital and it is hard to adapt analog to digital. I have not run across a vga male to dvi adapter. You see a lot of dvi male to vga male adapters. digital to analog is not a problem. There is no specific adapter part for your laptop I can tell you.
