[SOLVED] Optiplex 3040 - Dual monitors

[VicZav]

Hi there, new user here!

I have an Dell Optiplex 3040 that has one Display Port and one HDMI out, and two Dell E1916H monitors (which have one Display Port and one VGA ports each).

I just tested dual screening using Display Port > Display Port and HDMI > HDMI to VGA adapter > VGA to VGA and despite the image sucked, I can confirm that this CPU can hold dual screens. Then I tested Display Port > Display Port and HDMI > Display Port (without the so called "active adapters" as far as I researched) and the second monitor didn't worked at all.

So... Now I have some questions and I like to know if you guys could help me:

1 - Would dual screen work considering HDMI > HDMI to Display Port > Display Port to Display Port? Using Display Port to Display Port the max resolution available is 1366 x 768 (not the ideal, but it works for me). If i were to use the aforementioned setup, could I get the same resolution?

2 - Using HDMI > HDMI to VGA adapter > VGA to VGA I got a "native resolution" of 1920 x 1080, but the signal was awful - the monitor became automatically as a digital TV and the image was blurry... Is there anyway to change this "digital TV" configuration to another monitor?

Thanks!

You might want to list the version for your OptiPlex 3040 because there are three versions, MT, SFF and MFF. You're going to need either of these two:

depending on how you want to connect the monitor to the prebuilt system.

Also, would buying monitors that have native HDMI and Display port inputs be costly for you?
