Another 4K Update: Dell P2815Q 28″ Monitor

Some time ago, I bought a Seiki 39″ 4K monitor/TV for use with my Fedora 20 workstation/laptop. While the resolution was great, I just couldn’t get it set up where it wasn’t a pain in the neck. Literally.

But having a taste of the 4K good life, I was unhappy going back to the 2560×1440 resolution of the Cinema Display…

Right now, there’s not a ton of 4K monitors on the market – at least not affordable ones. But I happened to find a Dell P2815Q 28″ monitor at MicroCenter over the weekend, and decided to go ahead and pull the trigger.

Like the Seiki, the refresh rate at the top resolution (3840×2160) is much lower than you’d find with standard monitors. So if you’re looking for a gaming rig, pass this by for now.

But, the Dell has a few advantages beyond being a more manageable size for a desktop:

  • It has DisplayPort / MiniDisplayport inputs. The Seiki only has HDMI.
  • Adjustable height.
  • Rotation – though the video driver for Fedora 20 didn’t seem to like it when I tried to rotate the Dell to a portrait mode. Some more tinkering will ensue there before I figure out where the problem lies.
  • Three USB 3.0 ports (can plug into your desktop’s USB 3.0 slot).
  • Supports DisplayPort Multi-Stream Transport (i.e., you can plug in a second monitor for two displays). I haven’t tried this, yet.
  • Color seems better than the Seiki, though still a bit washed out. Not a lot, but not as crisp as the Cinema Display.

So far, no problems with the display, and I’m really happy to be back to a 4K desktop.

I’d only recommend getting a 4K display for early adopters, though. I suspect the prices will continue to plunge, while the quality and refresh rate will improve. But if you’re like me and spend way too much time at the computer, it’s worth considering.

Brief Review: Seiki 4K 39″ TV/Monitor

Just a bit ago, I blogged about getting a 4K monitor working on Fedora 20. Now that I’ve had a bit of time with the monitor, I wanted to comment on the experience a little.

Reviews on various sites really bagged on this monitor’s color/clarity compared to traditional computer monitors. While I don’t doubt discerning users might find flaws in this monitor, it’s just fine for my use case. That is, I spend the day using IRC, a few terminals, Web browser, PDF reader, mail client, and maybe LibreOffice.

If I’m using any sort of image editing/photo editing software, it’s strictly for cropping and re-sizing. So, honestly, it doesn’t matter to me if things are perfectly color-calibrated or if it’s good for gaming.

Compared to my 27″ Apple Cinema Display, I’d give it a B- or C+ for picture quality. But a small sacrifice of picture quality is well worth the extra desktop space.

Daily Use

The productivity increase I got from the 4K monitor was so great, I finish my work in half the time and have been promoted twice in the last week.

Uh, OK… not really. But we geeks are always chasing that tiny productivity boost, or searching to zap annoyances in our work day – and I’m happy to say there has indeed been a productivity boost and some zapped annoyances.

You can’t really quantify the improvement you get from a new setup like this, but if I had to… I’d say it’s 10%, maybe 15% more productive. I find myself spending less times tabbing through things, I can actually have four to six things open at the same time for a task without any need to tab through windows and find something. Example: Planning the Infrastructure.Next events, I can have a few emails or Web browsers open that have speakers’ abstracts, the Lanyrd page for Infrastructure.Next @ SCALE and Infrastructure.Next @ Ghent, a terminal for using middleman to update Red Hat’s Open Source Community blog, and still keep an eye on IRC/IM.

Ergonomics

The 39″ monitor is the same distance as the 27″ monitor, which admittedly is not the best layout ergonomically. The top and far right/left of the monitor are just high/far enough away that it’s slightly uncomfortable. I’d like to push the monitor back about another six to eight inches, but there’s not room on my desk.

Annoyances

A few annoyances with the setup so far.

First, the power management and Fedora don’t seem to get along. I had to turn off power management in KDE, because either Fedora was crashing, or the monitor wasn’t waking up again or taking a signal after KDE put the display to sleep.

The monitor has a sleep feature that kicks in at a regular interval, and the option to turn it off is greyed out in its menu. So, every few hours I get a overlay display on the monitor telling me it’s going to sleep in 60 seconds. So I grab the remote, mash a button, and it stays awake. (Or if I’m not at the computer, I have to power it on again when I get back to the desk.)

Not a huge deal, but also a bit annoying.

It has a PC input for sound, but I haven’t found a way to select that input while also using HDMI, which is annoying.

The only workable input to get the 4K resolution is HDMI. I’d like to use DisplayPort, but that’s not an option for this display. I’ve read a bit about “active” DisplayPort-to-HDMI adapters that might let me use the laptop DisplayPort successfully, and I’m going to try that soon.

tl;dr

For my use, the positives outweigh the negatives, though I debate whether I should have waited for the Dell 4K monitors. Higher cost, but probably better quality and easier to set up.

But, you get what you pay for. The Seiki is cheap and available now. It works well enough that I’m sure I’ll get quite a bit of use out of it. Worst case scenario, I could always use it as a TV if 4K ever really becomes a thing for Blu Ray/streaming video and replace it with a Dell or another proper 4K monitor when they become more available.

If you spend all day at the computer, I’d strongly recommend checking it out.

The 4K Desktop on Fedora

Like a lot of folks, I caught the “4K is for Programmers” post off Hacker News a few days ago (it’s here, but the link seems to be borked at the moment) and got to thinking about more desktop space. Much more.

My current setup, when not traveling, involves a 27″ 2560×1440 display – usually connected to my laptop. Even with that, I found myself tabbing through windows too often balancing terminal windows, browser windows, and mail.

Eventually I decided it was worth a shot, and ordered the Seiki 4K 39″ (SE39UY04) off Amazon. Unfortunately, didn’t seem to have much luck getting it going with my existing video card in the workstation or my laptop, so I wound up ordering a EVGA GeForce GTX760, and slapped that into the workstation.

It takes a few steps to get it going at its full resolution on Fedora 20, at least with my setup:

  1. Install the nVidia drivers as explained in this F19 nVidia install/un-install guide.
  2. As shown in this forum post, add a line to /etc/X11/xorg.conf in the Device section with several options that are needed to pass the right resolution:Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, AllowNonEdidModes, NoEdidMaxPClkCheck"
  3. Add the file /usr/share/X11/xorg.conf.d/10-monitor.conf, with this content:
    Section "Monitor"
      Identifier "Monitor0"
      Modeline "3840x2160" 307.00 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync
    EndSection
    Section "Screen"
      Identifier "Screen0"
      Device "HDMI-0"
      Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, AllowNonEdidModes, NoEdidMaxPClkCheck"
      Monitor "Monitor0"
      DefaultDepth 24
      SubSection "Display"
        Depth 24
        Modes "3840x2160" "1920x1080"
      EndSubSection
    EndSection

And that’s really it. Once I logged out and back in, it automagically detected the highest resolution and set the monitor to it.

Is the picture as nice as the 27″ Cinema Display? No. But it works fine, and after some tweaking (turn the Sharpness to 0, use the User preset) it’s a respectable picture.

I also tested plugging in the 27″ display and the 39″ display at the same time… yep, they both work. So if I can clear enough space on the desk, I’ll have waaay too much desktop space to play with. It has four outputs: HDMI, DisplayPort, and two DVI. I may see if it can drive all four just for grins, though I can’t imagine using that setup all day.. or having space for it on my desktop.

Given that the 4K post seemed to spark a lot of conversation, I do hope we’ll start seeing some focus on higher resolution monitors in the near future. We’ve been stuck for a few years with stagnant pricing on higher resolution displays (e.g. 2560×1440 displays) and not many options. Looking forward to working with the new biggie-sized desktop.

4K and Fedora?

Decided that mere 2560×1440 resolution was just not cutting it on the desktop, so I ordered a 39″ Seiki 4K monitor on Amazon. Should be arriving tomorrow. Wondering if anyone else in Fedoraland has set one of these puppies up, and if so – what video card and drivers you’re using?

I have a Dell dual-Xeon workstation with a nVidia Quadro NVS 295. A bit of googling suggests that it might have trouble driving something with a resolution higher than 2560×1600. Any experience with this video card and Fedora would also be welcome!
