It was time to upgrade my computer and screens so I could effectively process high res video. Not that my computer needed upgrading for every day work (3D Cad design) and leisure but high res video is a game changer, while I can processes 3 D environments just fine 4K video not so much. I had high end 26" 1080P monitors however they were 5 years old and not color certified, I had a triple monitor system and my plan was to go to 4 monitors, 3 side by side and a 34 ultrawide on top for wide screen video processing and cad environments.
What I discovered is that if you intend to process 4K video plan on spending more than the cost of the Drone. 4 Monitors aside even a single 4K Color certified monitor, the Video card and the processor to effectively do the procesing is a expensive proposition. Then you better add SSD drives to speed the processing up.
Through this process I learned that there can be a huge picture quality and price difference between color certified monitors and non certified (which accounts for most), not to mention there are very few color certified monitors available, not to mention price tag. I closely compared 2K vs 4K side by side and I could not see the video quality difference except I could not read text on the 4K because it was too small and the cost of 4K over 2K was substantial and not justifiable
Fortunately I already had a powerful processor and SSD, but in order to power multiple monitors at even 2K I had to upgrade video card to the 1080 GTX. Just a video card and 1 color certified monitor is more than the Mavic.
What I also found was when I watched the videos I color graded (Davinchi Resolve) on the old monitors I had a lot of work left to do as none were properly color graded because my old monitors were not Color, contrast or Gamma correct which left a lot to be desired on the new monitors.
1st off Color grading and or Color correction is often miss understood and very few software programs have true color grading options, Exposure, Contrast Hue, saturation, gamma is not color grading (it is only a very small part). You really need Davinchi resolve (which is free) or Adobe and a very small handful of others to really manage color correctly, especially if you are doing 4K then unless you have a monitor that is color certified or that can be calibrated (most cannot), then you need to buy the sensors to calibrate the monitor. Then to manage 4K or even 2 K you need a strong processor and Video card.
Basically it will cost more than the mavic to really be able to effectively process 4K video. Still unless you have a color certified or calibrated monitors it will be guess work at best.
I ended up buying three Dell 27 Inch Color Certifeid 27" and 34" ultrawide monitors and what a difference it makes in not only processing but watching the video I shoot.
IMO 4K is over rated. For those looking to upgrade monitors avoid Gaming monitors and low ms monitors they are more likely to artificially enhance or distort color.
If you were to buy 1 monitor for all around use and video processing the Dell U3415W is amazing on sale $599 at Staples (online only)
Now HDR will be a whole different animal.
