How do I change screen resolution for HP Compaq LA2205wg above allowed setting?

Also please clarify your exact MBP model to have a look in its specs, some 13" laptops have a native resolution of 1440x900 which may explain the exact behavior.

The model number should be listed on the bottom of the MBP:

If you cannot find this information you may also open the System Profiler / System Information and locate the model identifier:

Hey guys, I am having the same problem as listed above. Did you guys ever figure it out? It's strange because I have two HP LA2205 hooks up. One of them is letting me go up to 1680x1050 while the other is only letting me scale to 1440x900. What's' the

How are you connecting to the monitor(s) ?

1)

COMPUTER A -> MONITOR A

COMPUTER B -> MONITOR B

2)

COMPUTER A -+-> MONITOR A

|

+-> MONITOR B

if (1) then try the configurations:

COMPUTER A -> MONITOR B

COMPUTER B -> MONITOR A

what result do you get?

if (2) then how are you connecting to both external monitors?

What kind of graphics card do you have?

how much VRAM do you have?

What kind of adapters are you using?

Thanks for responding. I am using a Macbook Pro 13-inch (Mid 2010). I have two HP LA2205s. When I connect #1 – it gives me the 1680x1050. But, when I connect #2 – it’s max resolution is 1440x900 for both “best for display” and it’s the largest when I select “scaled”.

It’s option two. So the way I am connecting to #1 (the one showing 1680x1050) is just the simple VGA adapter that goes into the Mac. But, for #2 (only showing 1440x900) I am using a USB DisplayLink ioiogear adapter. Maybe this is my problem? The graphics for each monitor is "NVIDIA GeForce 320M 256 MB graphics”. How do I see how much VRAM I have?

Look up the device ( I searched for it using my favorite search engine) and locate the specifcations. I do not know which IOGear Display adapter you are using. The ones I saw for VGA were good to 1280x1024.

Did you try just one monitor at a time?

Can you change the radio button from "Best for..." to "Scaled" in System Preferences > Display?

Have you made sure that mirroring is NOT enabled?

can you post a screen shot of you Display options?

you have 256MegaBytes

I would review the specs fo the USB adapter and the refresh rate

How exactly do I do that?
