I recently bought an XPS 15 with a 4k display. I have a 1080p external display but there are horrible scaling issues on linux because the two displays have different dpi.<p>So I'm considering buying a 4k monitor and I can't find anything affordable (~$300) (I'm in India).
I spent a while researching 4k monitors a few weeks ago with a strong intent to buy one.<p>Ultimately I went for a 25" 2560x1440 monitor for ~$300[0] and it's amazing.<p>The problem is, a good SST 4k monitor with an IPS panel that runs at 60hz and supports 4:4:4 with a low input lag is going to be impossible to find at your price point.<p>Also keep in mind PPI. A 2560x1440 display at 25" is 117 PPI. A 27" 3840x2160 monitor has 163 PPI. That is a MASSIVE difference and at your price point that's about what you'll find unless you start looking for TVs and use them as a monitor.<p>The problem with TVs as monitors is they tend to have HDMI 2.0 ports and no display port, so you might have a hard time connecting it to your laptop unless your specific model supports HDMI 2.0 out of the box.<p>Their specs also tend to be a lot worse and to get a "good" one will likely run you double/triple your budget.<p>Then of course there's the whole size problem. A 36" 4k monitor is 122 DPI which should be awesome at 100% scaling but at 2-3 feet away you're going to have to move your head around like a maniac just to see each side of the screen.<p>[0]: <a href="http://amzn.to/2jF3WHp" rel="nofollow">http://amzn.to/2jF3WHp</a>
I was skeptical of my Yamakasi 4k monitor. But it has turned out well. Just over $300 for 4k.<p>It is obvious that it is actually 2 different panels on the inside. At one point after being on for a while, the two didn't line up. Rebooting the monitor fixed it. Yup. Monitor needed a reboot.<p>But I can't complain for $300.
