Dell Precision 5520 - DigitalVideo and Dell U-2412H

Hi,

I'm trying to connect my new laptop Dell Precision 5520 with Dell monitor U-2412H (now approx 4 years old] and I have troubles.

Laptop is having HDMI output only, Display is having VGA, DVI and Display port, so I need any conversion. 

HDMI to VGA conversion (analog ) works, but displayed picture is not fully sharp etc.... 

HDMI to Display port cable - (tested and working between my old Precision M4300 (Display port) and HDMI TV ( Panasonic AS ) doesn't works 

HDMI to DVI ( new cable) doesn't works 

In both digital connections, external display is not detected by video card. 

Built in display is UHD ( 3846x2160) with Touch panel, used display driver is (Intel 630 graphics ] 21.20.16.4664  ( dated as 21.4.2017 ) - but this numbering is incompatible with pure intel drivers versions  (there is noted river version like 15.60 ...

Is this Hardware or sofware issue ?

I don't see a U2412H display anywhere.  I see a P2412H and a U2414H -- which display are you talking about?

You definitely don't want HDMI to VGA because analog video never looks good.

DisplayPort to HDMI only works if the source is DisplayPort and the display uses HDMI.  It doesn't work in the opposite configuration that you're attempting.

HDMI to DVI should work just fine because HDMI and DVI actually use identical signalling as long as it's 1920x1200 resolution or below -- but since I'm not sure what display you have, I'm not sure what resolution you're trying to run.  If it's 1920x1200 or lower and it didn't work, you might want to try a different cable.  If you're trying to run a resolution higher than 1920x1200, HDMI to DVI won't work because DVI can only handle higher resolutions using dual-link DVI, but there are no simple converters from HDMI to dual-link DVI.  In that case, you wouldn't have any way to drive that display from that PC at the panel's native resolution.

Hi,

Sorry for delay due christmas holidays. Correct monitor type is U-2412M link based on to seller (www.alza.cz/24-dell-u2412m-d260038.htm) .  

I have reconnected cable again, but display is still not detected by my notebook. I will test same cable with my home monitor (EIZO)

Hi,

I have similar problem: Dell Precision 5520 cannot connect to Dell P2414H display with HDMI-to-DVI cable (source to display) with 1920x1080 resolution. This combination used to work when my laptop was Precision 5510. The OS is Fedora 27 for both combinations.

Thanks.

RE: Dell Precision 5520 - DigitalVideo and Dell U-2412H

Hi,

I have tested cable with my EIZO and cable is working fine with my new Precision 5520. ( display resolution was 1900x1200 )

So issue seems to be compatibility between Precision 5520 and DELL U-2412M monitor.

Is there any possibility to track data between Graphic adapter and Display ?

Regards, Vaclav

Follow up:

My problem connecting  Precision 5520 and P2414H display  by HDMI-DVI cable on Fedora 27 is resolved by installing RPMFusion NVidia drivers. A few issues in order to make them run: disable SecureBoot, disable SELinux, install gcc and automake. System BIOS version is 1.7.0.
