Mine is a BenQ FP241W 24" which was a rather expensive monitor at its time. I was quite surprised also to find that I bought it 7.5 years ago as it doesn’t seem like that long ago!
The main problem I have is space as this monitor already overlaps part of each speaker as they are also quite large (Hercules XPS 2.0 80 DJ set). Hercules call them monitors also, but for the sake of this thread, I call them speakers.
The vast majority of what I watch is in 720p or 1080p, although it would be nice having 4K for viewing and editing photos as well as for the extra workspace. For now, I’ll probably not replace my monitor until it either dies or good quality 4K displays became affordable to the point where I’ll take the splurge like I did with the speakers during last Amazon’s Black Friday.
My workplace monitor ended up being a different story. I’ve been working on content for pull-up banner displays and have been telling my manager several times that I really need a better monitor for this. In addition do being a basic 8-year old 21" TN display which had brightness shifts across the viewing angle, it had slight colour shifts according to what was displayed, e.g. dark grey appeared slightly green while light grey appeared slightly red. No amount of RGB adjustments would fix any of that. In fact, I even borrowed a Spyder3 Elite colour calibrator and its calibration profile was only able to provide a minor improvement in the colour shifting.
After spending a few hundred Euro on banner prints, my manager learned the hard way. The printed images were quite out on colour, e.g. a dark green in some areas appeared nearly black (since dark grey on my screen appeared dark green!), reds were over saturated and so on. He finally had an IPS screen ordered and when I set the two screens side-by-side in Clone mode to show what I had to put up with editing that content, the difference between the two were like night and day. The IPS display showed the artwork just like how it ended up being printed. After re-editing the work and getting new banners reprinted, they all came out fine.
