Extending desktop to 3 monitors - trouble with resolution
Hello Everyone,
Trying to extend the desktop on my HP Elitebook 850G1, using 2 HP Compaq LA2405x monitors. My original LA2405x can go up to 1920x1200 (connected through DisplayPort), yet the new one I just added wont go beyond 1920x1080 (connected through VGI)
At first I assumed VGA must be limiting the resolution but a quick search revealed that VGA can go much higher, so that doesn't seem to be the issue. I tried updating drivers and playing around with the settings, but I cant seem to figure it out for the life of me.
Any ideas?

By the way, it's not at all unusual for a graphics adapter to have a lower max resolution on the analog output than on the digital output(s).

How do I check what the highest resolution output available on my port is - I thought VGA was a standard that supported up to a certain resolution and as long as you are using VGA you would have access to within these limits (the only limiter should be the monitor).

Display adapters come handy for this, mostly used for laptop but could be used for a dekstop?
Garycase do you know if this could work on a desktop?
Just as an example on Amazon

Yes, the USB adapters work fine on a desktop. But the adapter you noted is unlikely to provide the 1920 x 1200 resolution the author is looking for ... I don't think it can go beyond the 1152 lines noted in the specs for displays more than 1600 pixels wide [It can apparently do 1600 x 1200 in 4:3 aspect ratio; but nothing above 1152 lines in 16:9]

Note that the manual has this note regarding the two: "... The DisplayPort delivers higher performance than the VGA external monitor port ..."
