According to Hardware Unboxed this problem goes away with the new generation displays. They are switching over to using a standard (LCD-like) striped pixel layout.
Must say my first generation Samsung display looks amazing both for gaming and programming though. If it wasn’t for the annoying smart-tv stuff, and the mini connectors, it’s a perfect monitor.
If only the PG34WCDN was actually available.. Asus appears to be very tight-lipped about when it will even go on sale.
There are three upcoming monitors that take advantage of this new Samsung ultrawide 360Hz V-Stripe QD-OLED monitor- the Asus ROG Swift PG34WCDN, MSI 341CQR X36, and the Gigabyte MO34WQC36. They are all roughly on-par, with the exception of MSI, who cheaped out on their DisplayPort 1.2a specification (UHBR13.5 instead of UHBR20) requiring the use of DSC to drive the 3440x1440 resolution at the full native refresh rate of 360Hz.
I have decided it is time to update my aging Asus PG348 34" Ultrawide (which has been one of the best monitors I've ever owned, and served me very well) - and will be replacing it with the PG34WCDN as soon as it is available.
> Within the past few weeks LG has announced RGB stripe OLED panels which will resolve this problem, but there aren’t currently any monitors available using these panels
3440x1440 @ 34" (110ppi): Asus PG34WCDN, Asus XG34WCDMS, MSI MEG X, MSI MPG 341CQR X36
Digging into this further, I also found another Asus panel that's closer, if not all the way there yet (5K would be, but this is 4K) to the usual Mac pixel densities:
3840x2160 @ 27" (163ppi): Asus PG27UCWM
I'll still be waiting for 5K @ 27" with the new tech, but I'm really glad to see they finally solved this!
