Using a Mac Mini on Dell U4919DW Ultrawide Monitor.

Hi Mark,

Thank you so much, as mentionned AMMMAC, it does feels AMAZING, finally !

You've made my day !

I was struggling with this since a couple of months, after purchasing both an LG 34" LG34WK95U and then a Philipps 49" 499P9H. Both not being able to display more than 1080 vertical, which is...sh*t for extensive desktop usage.

Using XRez screen scalling utility available on the web didn't help.

Your hints on dual USB-C + HDMI display with PBP Mode activated on the Philipps 49" works just fine at twice 2560x1440, where I was limited to one 3180x1080 since a couple of months, with much pain on my eyes.

I could set the menu bar on the left screen in order to avoid having the spotlight search fiel and all menu icons on the right far end...with an 120cm wide screen it matters to keep mostly focus on the center part of the screen.

I could set two (identical) 3120x1440 wallpapers to cover the desk field.

I am not to happy about the white balance between both side of the screen. It seems HDMI output a bit brighter than the USB-C output. So far I couldn't find a way to balanced it. But I am really not into the color settings of the monitor preferences.

Any inputs on setting equivalent brightness is welcomed.

You made my day ! So I can add Philipps 49" 5120x1440 screen real estate with new Macmini's, and on top of that Philipps stand seems of higher quality and design vs. LG's stand. And it has an integrated camera...Windows Hello....which means has to be supported by MacOS Mojave, for the moment with 10.14.4 the camera is displayed on PhotoBooth, not on FaceTime Yet.

Hopefully I will soon get a "double iMac 27" with no screen bezels at all, allowing much productivity improvement, togetherwith an integrated camera.

Please Apple, hurry up supporting DELL's, LG' Philipps...and SMasung's new 5K2K 49" Ultrawide screens !

Many users who have been waiting much too long (2013-2019) for those new mac mini's will thank you for it!

Bigoud_71 - I know paying another $100 just to get things to match is a pain, but you could probably get a Spyder to calibrate the color/brightness profiles of each monitor to get them to match. Outside of that, make sure they have the same color profiles assigned to them. Macs have to tendency to go nuts with their HDMI color profiles for some reason.

Really struggling here! Just got a new Mac mini i7 64gb 1Tb with a Philips 499p9h and I can't get the resolution up. Even tried the PBP option above but it won't show anything like 1220, certainly not 5120. Is the work around the EGPU with a Vega 64?

Anyone had any more luck with this or did apple help in the end?

Hi

My wife just bought me a stunning Mac Pro (12-core, 128GB RAM, 2TB SDD) and I love it.

Problem is I just received my Dell U4919DW ultrawide monitor and I thought it would be a perfect match. But I can't seem to get the monitor to give me anywhere close to 5,120 x 1,440 using HDMI and, whilst the Mac Pro has a few thunderbolt ports, there isn't much else to connect with.

Do you have any ideas?

I'd be very grateful for your input.

I have the same issue with my Philips 499P9H and 2018 Mac Mini. I guess we simply have to wait for Apple to sort this out and support this in an update. Seems like they simply do not support widescreen at the moment. Will try the suggestions for the 2 cables but for me it's not the ideal situation.

Got it working with the USBC-C cable that came with the monitor and the Moshi USB-C to DisplayPort cable I purchased today. I use the sound from the Mac mini (as it stands beneath my Philips monitor). I had to use SwitchResX to enforce these resolutions. Without it I can't pick the 1560x1440 for both 'screens'. Anyway, happy for now but I hope Apple would release a fix soon.

Ive given in, the only real fix I could find was to use a EGPU with a dedicated graphics card. Started with a Sonnet 550w EGPU and Vega 64 graphics card, the system I was sent didn't fit together (the sapphire Vega 64 nitro doesn't fit in the EGPU physically!) so that's sat on my desk awaiting return at £800. In frustration I ordered apples Blackmagic eGPU with a Vega 56 for £1100. Not great, but, it should run as well as a Mac Pro but with a 49' screen! frustrating. Will let you know the results when the new EGPU arrives tomorrow. I did fix this ultimately with the app to force the resolution but the quality isn't there at all in my opinion.

Forcing the resolution results in very bad pixel quality. Using two cables in combination with SwitchResX is a very workable solution for me. However, I am sure that Apple will fix support for widescreen monitors. Specially with the amount of designers that use their gear :) I am also using my monitor with my Windows Game PC which works fine on 5k maximum resolution. So it is really Apple who is to blame at this point.

I do not see the point in buying a 1000+ pound external graphics card just to get rid of one cable?

I was able to get my Mac Pro to push out 5120 x 1440 by connecting 2 Thunderbolt cables through HDMI converters, each at 2560 x 1440.

So effectively my Dell monitor is actually displaying 2 monitors driven by the same Mac Pro. It isn't ideal, but it certainly works adequately for now.

Thank you Mark from 2Much for explaining how he did this with his Mac Mini.

Same here with Samsung C49RG90 which is also a 1000GBP+ monitor I can't even use to its full potential on my Mac mini 2018. Yes... it works with 2 DP-USBC cables but the dock remains on one virtual portion of the screen which is ugly 'af'.... I hope this get fixed asap.

Hi everyone - any chance that the Mojave update (10.14.6) that just came out (I noticed it today and updated my Mac mini and a Macbook Air) may have resolved the Phillips 49 inch issue, enabling the display to run the way it should at 5120x1440?

Would love to switch back my PC to my 75 Vizio and get the Mac mini with the Blackmagicpro back together with the Philips 49er. Peace.

I was providing a possible solution for this issue. I do not have the monitor myself because of this issue, so I could not test myself. I assumed everyone in this thread is looking for a solution, not just me. My apologies if I offended anyone.

Anyway. Thank you for trying it out. Too bad it didn’t work 100%.

Did you get that 5120x1440 choice in previous OS versions? If not it might be an indication that Apple is working something out soon.

I am in the same situation as you where I need a dual monitor setup for programming. I would love to have a 32:9 monitor so that I can center stuff without the bezel. But a 1080p setup is not an option, so I will be better off with dual screens if a fix is far away...

I honestly don't recall - I don't believe so, but I'm really not sure if it's a technical or software limitation. I don't have Windows installed through bootcamp, so I can't even test that. Even with tools that allow me to manually set the resolution, i can't get it to display properly.

I'm a programmer as well, and having used 4k monitors for years, staring at text pretty much every day, I really, really, really miss the retina resolutions. I also have trouble getting both sides of the screen color calibrated exactly as a match. Ultimately, I think you're going to be happier with two separate identical monitors with floating arms. I will likely be giving this monitor away and going back to my old setup.

No, it isn't scaled - it's actually a change in resolution. If you download an app like easyres, you can see the resolution that you're using directly. That's just Apple's laymen "simplification." The MBP's are actually capable of generating higher than standard "2x" resolutions. I drove 2 4k monitors from my late 2013 MBP for a long time.
