Monitor higher Res setting required than available on computer

I purchased a 30" Dell monitor so I would have more real estate to edit graphics.

After plugging it into my laptop; using an HDMI cable, I  went to setup and discovered that I should set the resolution to 2650x1600.  But my computer's highest resolution setting is 1920x1080.  

Have purchased too much monitor for my computer?  Should I just set it to 1920x1080 run with that res, or would it make better sense to simply return it and get a monitor that doesn't overpower my computer?

One of the things I noticed was that there is an MST (Display port) plug that Dell provided a cable for, but my computer doesn't have a female plug that accommodates the terminal end of that cable.  

Oddly, Dell didn't include an HDMI cable so I had to go out an buy one.  Should that be a sign that I shouldn't be using one?

Laptops unless you go with what is called a Workstation usually do not have great video cards.  and that seems to be the limiting factor here.
If you really need more resolution and the opportunity to use the display port you probably need a desktop computer.
that said you do have a 30 inch monitor and even at 1920x1080, probably an awesome screen.
I use a 4 year old HP notebook at work and it does 1680x1050 on my 22" monitor, so you have me beat.

There is a slight chance that you may be able to increase the amount of RAM allocated to your video adapter as long as the video adapter is not a discrete card in the laptop.  Upon powering on the laptop press the key to enter the BIOS/CMOS setup (usually DEL).  Navigate through the menus until you find the video card settings, try increasing the available RAM for the adapter.  This will allow higher resolutions at the price of less RAM for programs.

Thanks, while it didn't actually provide a workable solution to the resolution issue it put the issue into perspective and helped me decide on an option.
