FZ190S VGA output quality

Hi everybody,

I just received my new FZ190S and have a little problem with it. I plugged a screen in the VGA ouput (a samsung Synchmaster 226BW) to work with a dual screen, but the image quality on it is quite poor. It is not ugly, but a little bit blurry, and the fonts are not very sharp.
If I plug my old computer (not a notebook) in place, also in VGA, the image is ok.

Is anybody here using a FZ with NVIDIA chipset in a dual-screen configuration? Is the image quality ok?

Many thanks in advance,

Smaon

 

what is the native resoltion on your samsung monitor? Because the native resolution on the FZ190 is 1280 x 800.

 

Hi,

the native resolution of the Samsung is 1680x1050, but I think this shouldn't be a problem, the FZ screen is at 1280x800 and the Samsung at 1680x1050.

 

Are you sure that you're broadcasting in 1680x1050 to the screen? And not 1280x800? What utility did you use to set up the screen?

 

I think you have to set your video output to the native resolution of your monitor to make the image crisp. That probably means that you will have to disable the FZ display when using the samsung in order to get 1680 x1050.

 

You can set the resolution for the external display and the laptop display to two different resolutions at the same time.

Gary: this is exactly what I do. My 226BW is at 1680x1050 and my notebook screen at 1280x800. I'm quite sure it's not a resolution issue. For me it looks a lot more like a signal quality issue, like if the VGA signal was noisy directly at the ouput.
For now the only solution I found is to tweak the screen settings to hide the problems as much as possible.

Thanks for your answers anyway,

Smaon

 

I have mine setup in dual monitor mode and it looks fine. My cable is even going through a switch. (I use the switch so I can decide if the display on my desktop is driven by the laptop or a desktop machine.)

I have to wonder if this might be a cable problem. I went through about three different cables before finding one that didn't give me "ghosting" when initially setting up my switch with my previous laptop.

Have you tried a different (higher quality) cable. Are you by chance seeing "ghosting". Look at a vertical line of black on white or vice versa. Do you see a second, very, very faint image?

Gary

 

Actually I already tried to change the cable one time, and the image quality changed from "horrible" to "not so bad". I must admit that the new cable is not from the highest quality neither, but what made me think that it was not a cable problem is that if I plug the monitor using the same cable on another computer, the image looks ok.

Anyway, I think I'll get a better quality cable to give it a try.

Thanks for your answer,

Smaon

 

Are you seeing any "ghosting" if so it is most assuredly the cable. Cheap cables are notorious for creating "echoes" of the signal. It was explained to me as being an impedance issue with the signal ringing off the ends of the cable.

Hello, I have a FZ11S and a FZ11Z at my design agency and both of them presents poor vga-out quality.
I already contacted sony vaio-link and they're trying to solve my problem.

I tried the dual-head configuration on 3 different setups and all of them have blurried images on the second monitor...

I tried it on:
- Mitsubishi Diamond Pro 920 - an old crappy CRT - Really poor image
- Sony SDM-HS75P TFT Monitor... blur...
- Dell 2007WFP TFT Monitor... less blur but still blur

I thought it was the driver problem and I went to a site (now I don't remember the URL) to download some unofficial nvidia beta drivers by hoping it will solve my problem but no luck

Right now I'm waiting for the Vaio-link answer...

BTW... all of them are on their native resolutions with different cables.

More.. I can see some kind of "refresh" on the Dell when the background color is dark grey.

You guys think is a cable problem? Should I buy a gold coated vga cable to give it a try?

 

By refresh do you mean "GHOST"? If so. more than likely you are running into a cable impedance mismatch or bad connection. I'd borrow a good cable from someone to try out. It doesn't have to be gold. All gold gets you is corrosion protection. Important if corrosion, even the slightest, is an isue.

Gary

 

It might be a "GHOST", I made an image with a black background and a 5 pixels vertical white line and I can see some faded white on the right side of the vertical line.

Do you know any good cable manufacturers? How can I check the impedance?

Thank you!

 

I can't make any specific recommendations on manufacturers. I have a good one I bought through a friend of mine who was in professional video production. You really can't check the impedance without an expensive piece of test gear.

get a good HDMI to DVI cable with a nice monitor and you will get a nice picture... the problem is when u have the FZ190 with an WXGA XBRITE-HiColor display next to your regular monitor u can see theres a real diference

 

Btw... it works on dual monitor mode? I mean extending my desktop with an HDMI to DVI cable connected to a TFT-LCD monitor.

Thanks!

 

Well, I bought this morning an HDMI to DVI cable and the results are pretty good. Sharp image just like connecting with DVI. Cost me 20€.

The desktop could be extended without any problems.
Unfortunately my VGA-out quality is still poor.

Anyway, if you guys have a few minutes, make a comparison with different cables by visiting the following site (Ponta Bicuda):

vga output for a sony fz11s is poor and blurry as well. It's is not a cable problem (cables are important though). Anybody out there has got a solution for this problem?

The sony-vaio-link is not deeplinked and the sony forum won't help me find the right thread...

Thanks...

 

i have the same proglem with my fz11s. i have connected 2 different lcd monitors to VGA port and the screen is blurry. I have tried to do almost everything to avoid the problem but it is impossible. So it is clear the problem is because of the nvidia 8400GT chipsetof the notebook.

 

Reported the issue to Sony (30nov07) and they have no solution for this problem yet.

Now they say something might be wrong with the vga output and their HEAD ENGINEERS are investigating it. As soon as they know more, the give me an update on the Sony Support Centre/Vaio Link/whatever it is called-case.

Hope they contact me soon!

Anyone else solved this issue yet? (I'm not sure to rely on Sony's Support Centre anymore...).

Cheers,

Rolf

 

Same problem with my VGN-FZ21M. Quite disappointed. Bought a Sony for the trademark quality ...

Opened a case at Sony support centre.

Will try with a DVI-HDMI cable.

Wish you a happy new year.

Fred.

 

Got a HDMI cable + HDMI DVI adapter : image is OK, but I can't change my monitor settings because its menus are software driven (but I guess there's no solution for that).
