GF Ti4800SE - Blurry Through normal D-sub/vga port

I've got a GF Ti4800SE card, connecting it to my monitor (21in CRT, running at 1600x1200@85Hz) through the normal D-sub port the image quality is very blurry. However if I connect it using the DVI port and the DVI-VGA converter the image is fine.
I’d have no problem with just using the DVI-VGA converter, however, I wish to use two monitors now.
I’ve tried, updating the bios, re-installing/cleaning drivers, running the comp with only the gfx card in.
I’m assuming I’ve just got a dodgy card, but I’m hoping otherwise as I can foresee it taking some time and a lot of hassle to return it for repair.
Any help much appreciated.
Thx.
Comp spec:
21in Sony E500 CRT
21in Sony 500PS CRT
1.4 TBird
A-bit KT7A-Raid

Cool, thx for all the replies... I checked back a few times and thought no one was going to reply. Impatient I guess.
Anyways,
Kingfisher: Yeah I've got the latest drivers and colour management profiles for both monitors, and the latest bios for my MB, and installed VIA Hyperion 4in1 drivers.
GlennVidia: It's a Ti4800SE-VTD8X
frOzEn: Yeah, I've tried from very refresh rate from 60-85. Still v.blurry.
Edit: Also for some reason when I connect both monitors the comp detects four!.
I've tried uninstalling the 'imaginery monitors' but the card just detects them again when I reboot.
Does anyone know if the 2 ports on the card are supposed to give different quality outputs, for non-LCD/TFT screens that is?
(BTW, I use a BNC cable with the Sony-500PS monitor, even though it's never seemed to make any difference to a norm vga-cable, since I've had it).
Thx, again everyone...
Oh, I spoke to the vendor and he said that it has a 2-year-manufacturers-warranty and to return it to MSI, and that it would take about 3-4 weeks for them to repair it. (BTW, It's 8 months old).

LCD becomes fuzzy after connects with T61p through VGA port

Hello,
I have a Dell E207WFP LCD which is previously connected to a Dell desktop through VGA. Today I connect it to my T61p through VGA using the same cable. I am able to setup the resolution as native resolution which is 1680*1050 @ 60Hz. However, I found that the screen is obviously fuzzy than connect to the desktop. The font is not sharp. I tried to adjust the cleartype font in Win7 and the bright and contrast in the LCD but nothing helps. I connect it back to the desktop and it works fine... Both computers run Win7. Could you please let me know what could be the possible reason? Thank you very much!
My T61p uses FX 570m video card.

This is hard to judge without a picture. It could just be a low-quality VGA port which is not a defect but an attribute or a nature of many laptop VGA ports.
Remember that the VGA is an analog-type video connector and some sort of blurriness is to be expected, especially at higher resolutions, this is because the GPU processes the image digitally as well as the LCD, but the VGA is analog so the image has to go through 2 conversions.
In conclusion: VGA is great for use in projectors and other devices with resolution no higher than 1280x1024. Above this resolution, defects are likely to appear.
For higher resolutions I'd suggest purchasing the Advanced Mini Dock which features the digital DVI port.

Hooking up to d-sub vga, hooking up to d-sub vga

question has any one hook up a apple tv to a old tv with out a hdmi plug, i do have a rs-232, or dvi in , or d-sub VGA and this is a new apple tv black. thanks bob

Welcome to the Apple community.
You may or may not be able to use DVI, you would need to use a separate audio feed and need to check that your DVI input supports HDCP. Please note DVI is not officially supported on the Apple TV.
There are hardware converters that will convert HDMI to various other types of output, however there are some issues with doing so that you should be aware of.
HDCP
HDCP compliant converters will not allow you to watch HDCP protected content such as that from the iTunes Store. Non compliant converters exist but we cannot discuss them under the Terms of Use for these communities.
Resolution and aspect ratio
I'm not aware of any converters that will scale the output from the Apple TV, any TV or projector which is used will need to be widescreen and support resolutions of 720p.

Just wondering what Apple's stand is on the issue with a flickering and a dark area appearing on imac 27"screen - forums seem to indicate this is not uncommon - and happens through normal use - so should be subject to repair (Sale of Goods Act - 6 years)

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

What cables do I need to connect MacBook Pro to the TV VGA port

Nov 6, 2014 7:01 PM
Hi,
The HDMI port on my Maxent tv is not working. I am hoping to connect my MacBook Pro to the TV via the VGA port on the TV to watch Netflix and movies. What cables do I need that will connect to a VGA port on a TV from my MacBook Pro (2.4GHz Intel Core 2 Duo)? And will that cable support audio or will I need a separate audio cable?
Thanks-
Sheri
OS X Mountain Lion (10.8.5)

Hey Sheri Lynn,
Thanks for the question. Our online store has a helpful tool that should guide you through the process of picking the best adapter for your MacBook model. You can check it out here:

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

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.

Jin Li

TV signal from T60p VGA port ?

Hi !
I would like to connect my T60p laptop to a TV. I saw VGA to RCA/S-Video cables available, but they require to have support for TV (RCA/S-Video) output through VGA port.
This is the recommendation from the VGA to Svideo/RCA cable seller: "please be sure to check the manual of your system to make sure the Video Card of your system supports TV (RCA/S-Video) output through VGA port. Not every Video card will work with this adaptor. Only certain Video cards which have TV Output function built into VGA port will work through this adaptor "
Can someone tell me if the T60p ATI Mobility FireGL V5250 video adapter supports this ? so I would not need to buy a more expensive VGA to TV converter, but just get the VGA-to-Svvideo/RCA cable.
Thanks,
Laszlo

If your older TV has either component (seperate RGB inputs) or VGA input with separate left/right audio jacks, you should be able to use either Apple's component or composite video cables. I have an iPad1 and I output Netflix from my iPad using the composite video cable as iPad1 doesn't output HD video, but standard VGA. Works great!

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

Toshiba Satellite L655-S51117 VGA Port Question

I have a Toshiba Satellite L655-S51117 with an Intel Graphics HD Video Card. There is no HDMI port on the laptop but I wanted to purchase a VGA to HDMI cable to connect to my LCD TV but it says the Video Card must support digital signal ouput through the VGA port. Does this particular card support digital signal output? I just want to be sure before I purchase go ahead and purchase the cable.
Thanks for your help!

I Got a laptop Satellite L655 for Xmas and I want to use it for my karaoke but I can't get it to work. I bought a new 15 pin to the RED, YELLOW and WHITE and S-Video cord but it won't work. My Old Laptop had A S-Video on the back and it worked fine. So how do I get this Laptop hooked up to my TV? It's an older TV but it has the red,yellow, white, and the S-video hook ups. Please any help on this? Yelsi

Audio would be stereo taken from the headphone port via a seperate cable to the converter box. It doesn't look like that machine has digital audio out, so no surround or whatever is possible.

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

Conecting 2nd monitor to mainboard integrated vga port on km4m

hello there, i got another monitor from my sister's old computer and want to get it working at the same time with my FIRST PRICIPAL MONIITOR, i got a Nvidia FX5200-T128 , that is where my first and principal monitor is connected ..... i use a KM4M-L mainboard, it has an integrated vga port, and i was wondering if i could plug my second monitor on there, andi did , but the system does not recognize it, i searched or an BIOS option like to enable that vga port , but was unable to find it... searched through all the mainboard's "users guide" but nothings talks about the integrated vga port. ..... i use 512 ddr for ram
i hope im giving all the information you need to help, if im not please let me know and i will be glad to .... any help here will be apreciated... as always

Unfortunatly, the onboard VGA port auto-disables when an AGP card is used. This leaves two choices for multi-monitor support. An AGP card with dual output, or adding a PCI card for the second output. Does your FX5200 have twin output? Many have 1 VGA and 1 DVI, which can be used simultaniously for dual monitors.
Ironicly, using a PCI video card, instead of an AGP, will usually allow the onboard to also be used.

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.
