SO HAPPY tonight!

LG has discontinued the DualUp LCD display ( 28MQ780-B ), it seems, sometime in the last 12 months or so. It is a 28-inch "4K"-class monitor that is nearly square, 2560x2880 in resolution with a 16:18 ( = 8:9 = 4:4.5 ) aspect ratio.

I have this display and it is the best display I have ever used in my life. I use it rotated 90 degree on the Mac, running in a "HiDPI" mode that is effectively 2304x2048, scaled. It looks amazing and is perfect for my needs.

I have used this as the main display on my Mac Studio since 2022. I always intended to buy a spare for when this one dies, but I missed the chance, so I setup an elaborate real-time monitoring system on eBay that has been alerting me the instant one appears on the site. They often go for twice retail or more.

This weekend one appeared that was local, and I talked to the seller and he told me it had only 490 hours on-time (which I've since verified), is flawless, and would meet me for pickup. He actually dropped the price and we did the sale outside of eBay. I paid about $200 over retail.

But, now I have a backup! My square, UNIX-perfect system can live on well beyond what it might otherwise have.

Bizarre source of excitement - but I'm so happy right now.

I have an LG DualUp ( 28MQ780-B ) LCD display, and I want a second one.

It appears that the unit is extremely near the end of its production run (if not beyond). I do not see these units available for purchase anywhere outside of a single retailer in Dubai.

If anyone has any info on where to source this display, I would be most grateful.
