I have a Lenovo Edge 15 that is proving to be simply awful for editing. (I'm using Adobe CC, PS & LR with varying Nik and VSCO plugins. The Lenovo is Windows 10, 64 bit.) When I look at my images on another monitor - even other laptops - the images I've processed on the Lenovo are flat, and lacking good contrast and tonal range. This is much more noticeable in color than monochrome images, but the disparity is there. I can even see differences between images from other photographers when viewed on the Lenovo and my phone. The big issue seems to be the lack of adjustable color settings for the monitor. Using the Windows 10 color calibration tool, I can set the Gamma and RGB. I use the Lenovo settings for brightness...but there is no setting to adjust the contrast. I've used the X-Rite i1Display Pro color calibration system and end up with a very flat and warm toned image on the screen. So...I have three choices as I see it: 1. Buy another laptop, with the most adjustable monitor I can find for it. So far, my research has shown the Dell XPS 15 (non-touch) to be worth considering, and not necessarily with the uber hi-res 'touch' monitor offered as an option. 2. Buy a MacBook Pro 15 with Retina Display, and make the switch from PC to Mac. (I understand the Retina Display is not adjustable, per se.) 3. Take my former studio assistant up on his offer to do my post/retouching work on his Mac setup; he knows what he's doing, and he understands how I see. Plus, his work is awesome! I also must use a laptop as I live on board my 34' sailboat. A desktop system is not an option, not up for consideration, and not doable. And having said that, the lighting is horrible in the boat - all LED - and that is most certainly a factor in the lack of quality of the image edits. And going off topic for a second, the boat is also a factor in my considering a move from PC to Mac, as we already use an iPad for navigation. For the near term, I'll be using my former assistant's talents for post work. But sometime in the next couple of months, I will need to find a solution which will work for my lifestyle. I'm no longer a working pro, but from time to time I sell a print here and there, and do post images on the web, etc. Quality is important. Any input is appreciated. Thanks!
