My requirements are:
- Good for frontend work. High DPI, high resolution. Not excessively blurry, or retina-like. Good color representation.
- Single monitor setup.
- Be able to see 3 screens side by side comfortably, with my coding screen at minimum 16px font size
- Around 1-1.5k.
- Can be driven by a Macbook Pro
I am currently comparing a Dell 43" 4K Ultrasharp screen (dell u4323qe) vs a LG 40" Ultrawide 5kx2k (lg 40wp95c-w). I don't have any experience using an ultrawide vs a very large screen so feedback around that decision (or recommendations of other monitors) would be very useful.
Neither of these is “High DPI” by any stretch of the imagination.
If you want high dpi (particularly with macOS) you essentially need to aim for ~220PPI, the further you drop below that the worse it will be.
Personally I think the best bang-for-buck on a high dpi display is the Dell 32” 6K. I got mine for around $100 more than what Apple sells the 27” 5K (with the fancy glass and adjustable stand options) here.
If you can live with 27” there are a few choices of 5K available now/soon.
