Screen flickers in 1680x1050 - samsung 2232BW plus

I recently purchased the samsung 2232BW Plus as a monitor to use with my laptop. I'm using the vga cable and NOT the dvi cable. The laptop is an old dell inspiron 1100.

I thought for sure I was having interference on the monitor from my power supply that sits on my desk so I removed the power supply, my cell phone, my speakers and anything that could possibly emit any current away from the monitor... but the problem persists.

The problem with his huge monitor is that everything is distorted at other screen resolutions. 1680x1050 gives the most clear picture and ability to maximize viewing space.

I updated the driver from the samsung website and still no luck. I thought it may have been my video card but the screen works fine for a period of time then begins to flicker. Sometimes, after extended periods of flickering, I can hit the auto-adjust button on the monitor itself and it will correct itself.... sometimes it will not correct itself.

I checked the refresh rates and the max refresh rate on this resolution is only 60Hz... I thought updated the driver would allow a higher refresh rate but no luck on that either.

Is this a hardware issue with the monitor or a problem with my setup? Should I return the monitor for another one?

Many thanks in advance for your assistance.

    Well, if you read my full post you would see that I stated it does work in that resolution. Sometimes for hours and sometimes for only minutes and then starts to flicker.

    Is it the refresh rate? the video card? the driver or is it a monitor problem? I think I pretty clearly laid out the situation.

    The laptop is a dell inspiron 1100 - how can I find out if it contains a video card powerful enough to feed this monitor? Or can this even be the root cause of this issue?

    I have a SyncMaster 920NW that does the same thing in its native resolution, also using the VGA cable rather than the DVI. I'm using a relatively new Lenovo workstation with Vista.

    I think this may be a video card/monitor combination problem, because the monitor worked fine its native resolution on my other computer for months while plugged into a VGA cable. By the same token, my current workstation can drive any other monitor on that VGA cable with no flicker.

    I get this problem at any resolution above 1024x800 when attached to my HP (with Intel 965 chipset).

    However,when plugged into my Sony Vaio I do not get this problem.

    Did you sort it out?

Can your monitor AND PC put out that resolution??

I don't think your Dell and put that out, if it's an "old" machine.

This also happens to my vga connection to my TV.
I used my tv remote "auto" button to re-size it to fit correctly.
If your monitor/TV does not have the adjustment, you may need to
supply your vga compatible device with your monitor's driver software.
This tells your computer what monitor specifications you have.

What component failed in my 17"CRT 753s model samsung moniter?


Your vertical deflector circuit is going out. This is really not economical to repair, the chip alone is $12-15 plus if you have any other parts in the circuit going out plus labor. You can pickup 17" CRT monitors for less than $15 from goodwill or craigslist.

Sorry to say but I think its time to retire your 753s

Could be a problem of Leaky front panel switches causing the monitor to Auto adjust on it's own.
You need to be technically able to open the monitor and try repairs which maybe simple although parts may not be readily available.
