Dell Vostro 3750 with Dell U2515H monitor resolution problem

Hi

I've got DELL Vostro 3750, and I bought Dell U2515H monitor for second display.

I can set only maximum 1920×1050 resolution, instead of the optimal 2560×1600 of the monitor. 

I'am connected them with hdmi cable.

Please help me solve the problem!

Peter

The U2515H HDMI in port can do up to 2560x1440 60Hz. But the U2515H does not dictate the resolution. That is done by the capabilities of the laptop GPU video card. The 2011 Vostro 3750 HDMI out must be limited to 1920.

Hi Chris,

Intel® HD Graphics 3000 supports a maximum display resolution of 2560x1600.

The other GPU of the laptop is NVIDIA Geforce GT 525M has the same maximum display resolution of 2560x1600.

I don't understand, why Vostro 3750 HDMI works maximum 1920. Smiley Sad

I wonder if the culprit is the cable? What specific cable is it? Perhaps if you change the Hz from 60 to something less you can get higher resolutions.

The cable is OK, it's 1.4. My problem is not black picture on monitor, but I could't change the resolution os 2560×1440.

u have to use "Second Screen only" .. i mean if you are using your HDMI cable u should see the picture from the second screen only .. you cant use both screen at the same time

i hope u understand me

Thanks for the tip, but it did not work. The maximum resolution is the same as in dual display mode. Smiley Sad
