Even on this relatively small 15" screen, the difference between viewing 4K and 1080 video or jpeg images is significant, in my opinion.I have recently purchased a 36" Seiki 4K tv (£200) to use as a monitor and this shows up the difference between 4K (UHD) and 1080 (HD) to an even greater degree. YOU DO NEED A PC/LAPTOP CAPABLE OF OUTPUTING a 4K HDMI SIGNAL.I feel that photographers (up to now) have really concentrated on the hardware for CAPTURING the images ie cameras and lenses. To me the OUTPUT or viewing end is just as, if not more, important.To view your results you can either produce colour prints (A4, A3 etc) OR you can view your pictures on a screen. The added pleasure of viewing my photos/video at 4K resolution has justified my investment in 4K. To view high quality images produced on a high quality camera/lens on a 1080 or worse 720 display seems a bit futile considering the advances in today's screen technology. A mid range camera jpeg image on a 4k display will give a superior viewing experince to a high end camera jpeg image on a 720 or 1080 display.I should think that 99% of image viewing is on screen rather than expensive, large prints. However....a high quality image from a top flight camera/lens, viewed on an ultra high definition display will undoubtedly give the best results overall......quality prevails !!To your specific point on grabbing 4K images:You can grab jpeg images using VLC player. Image grabs are not dependent on the screen resolution of the PC but on the resolution of the video file. For example if I grab an image from AVCHD footage taken on my Panasonic FZ72 the resulting jpeg will be  1920 by 1080 pixels. If I grab a jpeg from footage taken on my Panasonic G7,  the jpeg resolution will be  3840X2160. Furthermore these images can be grabbed from a non 4K PC, provided it can play the footage.HOWEVER, viewing the 1080 or 2160 image on a 1080 monitor will only display at 1080, whereas a 4K monitor will display the 1080 jpeg at 1080 or an "upscaled" jpeg and display the 2160 jpeg in true 4k (UHD) ultra high definition format (4 times the detail !!),  a totally different viewing experience !Sorry if you are already aware of this but I thought it was worthwhile describing the image grabbing process and viewing experience in simple terms. Hope this helps and adds to the debate.Scotview</blockquote>
