Review on LG 28MQ780 B DualUp Monitor: DCI P3 2560X2880, Dynamic Action Sync, Flicker Safe, Reader Mode, HDR10, 28MQ780-B.AUS, HD - Ultimate Visual Experience for Enhanced Productivity by Victor Haler

I use this display in the office with two computers connected to it via HDMI ports. The screen is in a top-to-bottom split portrait format, so each PC screen displayed is 2560 x 1440. Compared to my other screens, the clarity of this screen is a bit soft. There is the slightest blur, it's not a display limiter, it's still very legible, but I've also connected 2 other screens and it's not as sharp compared to those other screens. I was hoping for software, although I could dynamically select one of the two screens and make it full screen with a hotkey combo or something on PC. But it seems that the only way to make either screen full screen is to use the on-screen menu system with a physical button on the bottom of the screen in my orientation. So it's not as elegant as I'd like, but it works, it just takes a little extra effort. The KVM feature was another thing I was looking forward to and it kind of fell short. KVM requires both PCs to be on the same TCP/IP network as it uses IP. It then changes your Windows Firewall and leaves huge gaps in incoming connections. For incoming connections, there are 14 rules that allow all ports. It should only disable your firewall, since that's essentially what those rules do. So as soon as you compromise the security of your computers to make KVM work, press the hotkey to toggle. For me it's the right arrow, which is the default. Only after a while it stops working, I don't know why. Like it worked 10 minutes ago. I entered this review and now I try the hotkey and it doesn't toggle. The other problem I've encountered is that if what you're running on the second PC causes Windows UAC, that also stops your KVM control. I had to use a dedicated keyboard on a second computer to click "OK" on UAC, after which KVM worked again. I guess for now I'll just use a real KVM switch to make K and M switching more reliable. I don't have the patience for temperamental stuff when I need to get the job done. So TLDR: connecting multiple computers and displaying them on screen at once is pretty decent, if a bit dull in focus. Switching between keyboard and mouse requires work on these computers, they are very unreliable in their current state and leave gaping holes in your firewall working.
