Can't get 2048x1152 native resolution on SP2309W monitor

Question

I had been running the native 2048x1152 resolution on my SP2309W monitor with no problems on a VGA to VGA cable. I bought a VGA to DVI adapter, attached it to my VGA cable, and then plugged it into the DVI port on the monitor. The monitor didn't register anything, so I decided to forgo the entire DVI connection and I went back to my original VGA to VGA cable. When I plugged it back in, I no longer got the same resolution options I had before with the monitor, like the 2048x1152 native resolution. Instead, my largest resolution options are now:- 1920x1080- 1920x1200- 1920x1440- 2048x1536 Currently, I have the monitor set on 1920x1200 resolution since it's the closest to the native resolution and it's also the only one that the Dell monitor registers compatibility with. Again, this all happened the moment I tried plugging the monitor in using a DVI cable (which ultimately didn't work) and then returning back to the VGA cable. I have tried unplugging the VGA and power cord for the monitor and holding down the power button on the monitor for 30 seconds and restarting my computer. I've also tried resetting the monitor back to factory defaults as well as reinstalling and updating the video driver on my computer. I just can't seem to get 2048x1152 to show up as a resolution option anymore.Any help would be greatly appreciated.

Try removing and reinstalling the video card driver.

I'm noticing if I remove my VGA cable from the monitor and reattach it loosely, half the time I'll be able to get the native resolution but the screen shakes the entire time from then on. When I restart my computer, the resolution options will revert back to what I listed above and I have to reattach the VGA cable again. I'll unplug and replug again and again while fiddling with the VGA port on the monitor until finally the native resolution pops up.

Could the VGA port on the monitor be defective?

Not likely. Have you reseated the video card in the motherboard slot?

Thank you for helping me out with this, Chris.

I have not reseated the video card. I'm running on a laptop, so I'm not sure about prying it open to do this.

Like I said before, it had been working perfectly until I tried using the VGA-to-DVI adapter and then went back to VGA. My problems started immediately after. So far, my best bet is still just to reattach and wiggle the VGA cord many, many times until I get the shaky native resolution.

So on the monitor end, your moving the cord?

Yes, I've been reattaching and wiggling the cord from the monitor end. I've done it on the laptop end too, but the monitor end is what usually ends up giving me the native resolution occasionally.

Contact Support and get the monitor replaced.
