partly because I've already picked up the SSDs because they're
going into my current machine first (<a href="https://utcc.utoronto.ca/~cks/space/blog/linux/PlanningHomeSSDShuffle">when I get around to that</a>), and of course they're SATA. My
impression is also that using M.2 today cuts down the number of overall
devices you can have in your system because of bandwidth limits,
although I haven't decoded exactly how many usable SATA ports I'd wind
up with on various current motherboards.</p>

The HDMI standard has many optional features, so just because a product "complies" with a certain version does not mean that it implements all its features. I know for example that 4k@30 is an optional feature in HDMI 1.4.</p>
<p>According to the official <a href="http://www.hdmi.org/manufacturer/hdmi_1_4/hdmi_1_4_faq.aspx">FAQ</a>:</p>
<blockquote><p>How will I know which HDMI 1.4 features are implemented in a device?</p>
</blockquote>
<blockquote><p>Shop for the specific features that interest you, rather than shopping for an HDMI version number and assuming that a certain feature is supported. Since many of the capabilities detailed in the HDMI 1.4 specification are optional implementations, it’s the responsibility of the manufacturer to tell you what features are supported in any given device.</p>
</blockquote>
<p>And according to a <a href="http://www.planar.com/blog/2014/12/8/whats-new-about-the-hdmi-20-standard/">third party source</a>:</p>
<blockquote><p>It’s also worth noting that HDMI version numbers don’t accurately reflect the feature set of the products. So merely saying the product is HDMI 2.0 compliant in itself doesn’t say a whole lot because almost every feature within that standard is optional. So for example you could have an “HDMI 2.0 compliant product” that doesn’t support 4K or 3D or deep color or audio or many of the other features for that matter. And so in order to properly reflect the feature set in the product, what really should be said is HDMI with 4K support or HDMI with 3D support or HDMI with 4K 60 4:2:0 support. In most cases when people are asking about HDMI 2.0 support, what they’re really asking is if the product supports 4K at 60Hz. </p>
</blockquote>
<p>I would stick to DisplayPort if at all possible. It saves a lot of headache and disappointments.</p>

support for DisplayPort 1.3 (in the form of resolutions and refresh rates
that require more than DP 1.2). I suspect that one reason for this is
that even current generation Intel graphics can't do full 5K resolution,
so anyone doing this now or probably in the near future is going to use
a graphics card anyways. This is also what I'd expect to have to do
to move to 5K, and that probably wouldn't be for several years for me.</p>
<p>James: I'm currently using a Dell U2412M at 1920x1200, so 1440p isn't
enough of a resolution jump to attract me. I also don't want to lose
any physical vertical display space and my current display is 16:10,
so I think any 16:9 display I switch to needs to be clearly larger
diagonally in order to keep that vertical height (the Dell U2515H
would lose me some, for instance, despite the increase in vertical
resolution).</p>
<p>mtk@acm.org: Software support for 4K is going to be an exciting can of
worms, since I use <a href="https://utcc.utoronto.ca/~cks/space/blog/sysadmin/MyDesktopTour">a very custom desktop</a>.
But I figure the benefits will be worth it.</p>
