If you are looking for a 4k monitor with vga input there are some models which have it.
Dell UltraSharp 4K Monitor
The Dell Ultrasharp displays are one of the most popular monitors for graphic design work. They have great resolution, refresh rate and color accuracy. The Dell Ultrasharp U2711 is a 27-inch monitor with a 4K resolution which is four times higher than 1080p resolution. This means that you will get more pixels per inch, making text sharper and photos look better. One of the other benefits of this monitor is its 1 millisecond response time which means that it will react very quickly to most moves you make on your computer screen. It also comes with DisplayPort and Mini DisplayPort inputs so you can connect it easily to any computer or laptop (as long as it has DisplayPort output). In addition to this, there’s an HDMI port available as well if you want to connect your Xbox One or PlayStation 4 console into your setup instead! Finally, this model comes with built-in speakers that provide decent audio quality without having any external speakers around like some other models may require!
The Asus MX27AQ is a 4K Camera Monitor that has a maximum resolution of 3840 x 2160. It has an IPS panel and 60Hz refresh rate, making it suitable for gamers and video enthusiasts alike.
The Asus MX27AQ features two HDMI ports, one DisplayPort, one USB 3.0 port, and one USB 3.0 hub with several ports on board (3x USB 3.0 ports). It also comes with a power adapter that outputs 60W of power to the display itself—which is enough juice to get you going without needing another AC adapter (although you’ll want to make sure your graphics card can support the higher resolutions before buying).
The LG 27UD68-P is a 4k resolution monitor with a vga input.
It has a 21:9 aspect ratio, which is wider than the more common 16:9 aspect ratio on most monitors. This means you'll have more screen real estate for working or gaming.
The response time is 4ms, which means it will be able to display fast moving images without any ghosting effects on the screen. This makes it well suited to watching movies or playing games with lots of action in them, but not great for professional work where you need truly accurate colors and shades (like graphic design).
Its refresh rate is 60hz and it has an average contrast ratio of 1000:1 and brightness level of 300 cd/m2 (cd/m2 = candela per square meter).
You can find cheaper options that offer better color accuracy and contrast ratios than this LG model does, but they lack some other important features like USB ports or headphone jacks built into the monitor itself instead of having to use one of your computer's ports — which could be useful if you're using multiple monitors at once!

Built with WQHD resolution of 3840 x 2160 pixels for stunning graphics on screen, this monitor delivers crisp detail and vibrant colors at every turn. Whether you're creating graphics or streaming movies from Netflix or Hulu Plus on your PC to your TV via HDMI input — it doesn't get any better than this!
If you are looking for a 4k monitor with vga input there are some models which have it.
VGA stands for "Video Graphics Array" and is an analog interface which was widely used in computers from the 1980s until about 2012. It has since been replaced by HDMI connectors for projectors, monitors and other devices that need to output video signals. In addition to being replaced by newer technologies, VGA ports have also been phased out of most modern PCs because they can only transmit text at a maximum resolution of 800 x 600 pixels (although they were capable of being adjusted upward).
It is possible to find a 4k monitor with vga input but it is not common. It is best if you do your research before making a purchase and make sure that the model you are looking at has this feature.
