I bought an
LG 27UD88-W the other day to go with a new build - running off a GTX 1070 (Asus Strix OC). I also use it with my 12" MacBook. I bought that monitor specifically for USB-C for future Macs.
It's
fantastic for my games - which the card can run at max settings in full 4K at well over 100 FPS, which I vsync to 60 - and works perfectly with my MacBook over USB-C too. However, just using it for regular usage in Windows delivers an experience that is far from perfect. Windows is
not quite ready for large, HiDPI screens - macOS is far superior in this regard.
I haven't properly used Windows for the best part of 12 years, so this is not something I realised Windows was so far behind with. It's certainly not disastrous, but there's a lot of pixelation in various system apps, let alone third-party ones. This is caused by the HiDPI scaling in Windows. The HiDPI scaling on macOS is far, far better. You
will need to use scaling, as the UI is unusable in native 4K.
The pixelation sticks out like a sore thumb to me, having had pretty perfect "retina" or HiDPI Macs for over 4 years now, but if you've been using native 1080p or 1440p, then it's still going to be a huge improvement...80% of the time.
HiDPI 4K or 5K displays will be the norm in the not-so-distant future, but Windows users who use them today are still suffering early adoption issues.
Specifically for you:
- I would
hope that MS Office has been optimised
- Chrome is absolutely fine for me
- Photoshop should be fine too, since Adobe have supported HiDPI for a very long time
Your graphics card should be more than capable of handling that - it's on
nVidia's list of cards that support 4K (page 2).
Just my 2 cents based on my 12 days with a 4K monitor with both PC/Mac.
