    Another 4K Update: Dell P2815Q 28″ Monitor 

    Some time ago, I bought a Seiki 39″ 4K monitor/TVย 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 

    Seiki 4K on Fedora

    Seiki 4K 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.

      Eh, I’m not really feeling the TV-sized displays. I’m much more interested in replacing my 2x U2211s with 2x UP2414Qs:

      now *that’s* how to use 4k ๐Ÿ˜‰ Just waiting for the price to drop a bit.

      4K is a lot of pixels, but it’s still cheaper to buy them in smaller chunks. Four 20-inch 1080p monitors will likely cost less than the single 4K panel, and leave enough to pay for a good 4-monitor stand. Plus you don’t have to worry about finding a graphics card (and interface) that can handle 4K at a suitable frame rate.

        That’s actually not the case. This monitor was ~$500.

      The new Lenovo 28″ 4K screen is $799 (possibly with touch screen?), and with built-in android it is $1199.

      Dell have a new 4K 28″ at $699

      Asus also have a new fast 28″ 4K at $799.

      I am currently running a Lenovo Ultra Wide 29″ monitor with 2560×1080 resolution. Hooked up to the mini-DP connector of my Lenovo X1 Carbon laptop Fedora 20 autodetects it and runs it at full resolution without any problem. Intel drivers on linux rock. I look forward to getting a 4K screen for testing. ๐Ÿ™‚

        2560×1080? That’s unusual. I thought the standard there was 2560×1440.

        I have a 2560×1440 that works just fine with my Lenovo ThinkPad (T530) as well. There really is a difference with the 4K, though. Soooo much real estate!

      I was struggling with getting the 39″ 4k Seiki running with an AMD/ATI Radeon HD 6450. The best I could do was 15 hz with a cut down dot-clock in a custom config file similar to the above. Turns out the problem was related to the graphics card and an older display controller version in the HD 6450 chip. Upgrading to a Radeon HD 7770 fixed the problem. I now get 30 hz refresh with an absolutely stock Xorg config. (The lag at 15hz was driving me crazy. Typing quickly meant that I’d be a few chars ahead of what the display was showing me.)

      Love the display size. The resolution is 113 dpi, which is just about right for me.

    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!

      I just built a system with a Haswell i5 4670 and a Gigabyte GA-Z87X-D3H motherboard. The integrated graphics card will do 4096×2160 @24Hz on the HDMI port according to the manual

        Have you tested it with Fedora and a 4K monitor?

        • Moochiek 6:16 pm on April 15, 2017 Permalink | Reply

          The Quadro NVS 295 runs at 4K on my Samsung 28″ UHD monitor via DisplayPort, driver version 11/14/2016 (Windows 10 update version).
