Please help me with my SiS661FX Problem.

I bought a Samsung SyncMaster 2253BW LCD monitor. I followed the installation guide, which involved installing a new driver specific for the monitor. When I plugged the new monitor in, I unable to set the resoltuion high enough through the display settings. Also there were a lot of moving pixels on screen.

I uninstalled all the drivers for both the new monitor and the graphics card. I then downloaded the latest drivers for both. After this I was now able to set the resolution correctly to the optimum setting, but the moving pixels problem remains.

In the Driver Mode Setting there is drop down menu in which I can only select CRT and no LCD. The LCD specific drop down menu is greyed out and unavailable. Is this where the problem is coming from? I checked on the SiS website and the product information for the 661FX claims it can support TFT-LCD output.

I also noticed that it makes no difference whatsoever when the Samsung driver is installed, and when it is not installed. Ive tried both the analogue and the digital specific drivers. There's no change in the display.

I am using XP sp3.
The monitor is connected on the regular cable, not the DVI.

Thanks!

Welcome to PCHF - the people here will help..........

Try the DVI cable route which I suspect will cure your problems....... otherwise could be faulty monitor.

Hi folks!

Segadude3000,
Yeah that is the monitor.

elpmek,
There is no DVI output on my PC.

Thank you

Do you know what Graphics Card your using? (elpmek should jump in anytime now)

From what I have seen, the SiS 661FX is a onboard video chipset i think.

I cannot get the actual SiS 661FX driver link in here...

SiS is onboard video...you may want to try purchasing a graphics card and seeing how that works.

I have a PC with SiS video, its not up to much and really onboard video is only intended for basic use and is a bit dated in most cases.

You may want to try booting into Safe Mode and seeing if you still have the video problem.

Also you could buy a DVI-VGA cable which may or may not help. But it would allow you to connect to your monitor via DVI and then to your PC with the VGA end.

Also there is something called a DVI dongle which does the same thing. I think a new graphics card would eliminate the problem though. Some you can get quite inexpensively.

For example:

Sapphire X1550 128MB with up to 512MB HyperMemory DVI VGA TV out PIC-E Graphics Card - Ebuyer

If you do want to buy a new graphics card, make sure you buy the right type (PCI, PCI-E or AGP). If you are unsure just ask here.
