Dell U4919DW (UltraSharp 49 inch Curved Monitor) #108

Open ryanerwin opened 4 years ago

Completely off topic ranting...

I've been using this monitor for almost a year now and it's still fantastic... Highly recommend this if you're in the market for a new premium display! Even though I don't usually like curved displays, this would actually be improved if they made an even bigger curve on the two edges... Paired by my Dygma completely split keyboard and standing desk, this is ergonomic heaven compared to the back pain I was struggling with each time I hunched over the keyboard...

Please let me know what else I can do to assist with getting DDC support for this monitor.

The most important missing item in the default profile is "Input Source", which ddc is only showing as analog or digital but the OSD gives:

I also read that using the ddc power off should function the same as the monitor power off, however these Dell UltraSharps have a built in USB hub for your keyboard and mouse, and when you ddc power off the monitor, the internal hub doesn't power down so any keyboard lights will also stay on...

Otherwise most of the "default" profile based options work, including:

Unfortunately the "Input Source" by default doesn't detect the monitors actual menu options:

Instead I only get "Analog" or "Digital"...

I'm not familiar enough the Degauss to understand the operation of that...

I copied DELLA0F0-DELLA0F4 xml files and revise to match the Monitor EDID (also names too). It works for PBP/PIP mode . Looking into the value to switch USB inputs while using PBP/PIP.

@eunchan thanks for the tip.

The current monitor database does include files for "Dell UltraSharp 38 Monitor (Model 2017)" and these files do somewhat work for the Dell UltraSharp 49 (Model 2019). Note there are different EDID's for these monitors, depending on how the device is connected...

DELA0EF.xml DELA0F0.xml DELA0F1.xml DELA0F2.xml DELA0F3.xml DELA0F4.xml via HDMI1 1.4 https://github.com/ddccontrol/ddccontrol-db/blob/master/db/monitor/DELA0EF.xml via HDMI1 2.0 https://github.com/ddccontrol/ddccontrol-db/blob/master/db/monitor/DELA0F0.xml via HDMI2 1.4 https://github.com/ddccontrol/ddccontrol-db/blob/master/db/monitor/DELA0F1.xml via HDMI2 2.0 https://github.com/ddccontrol/ddccontrol-db/blob/master/db/monitor/DELA0F2.xml via DisplayPort https://github.com/ddccontrol/ddccontrol-db/blob/master/db/monitor/DELA0F3.xml via USB Type-C https://github.com/ddccontrol/ddccontrol-db/blob/master/db/monitor/DELA0F4.xml

Looking into the value to switch USB inputs while using PBP/PIP.

I've found that even using the basic "input settings" > "input source select" to switch inputs, the USB input isn't reliably selected to match the input source, the way that it's matched when using the monitor's hardware buttons.

Did you find the solution?
