c49j89-lc49j890dkuxen vs curved-chg90d

[m4gicas]

Hi all,

i am considering buying one of the two monitors mentioned in the subject, but i am struggling to figured out some differences. from what i understand so far:

1.  cj89 has lower response time and brigness
2. what about QLED? seems like cj89 do not have it?
3. cj has USB-C ports and has this capability of using 1 keyboard and mouse for multiple devices connected to the monitor while chg90 do not have this capability?
4. any other differences? based on https://www.techradar.com/uk/reviews/samsung-c49j89 article the should be only differences mentioned in point 1, but seem like there is more, hence the confussion on my part.

overall seems like chg90 is a better option apart from point 3, but i really need point 3 as i have 2 PCs.

also, do we know if there is a samsung monitor like those 2 but with higher resolution? it was mentioned in that article that samsung is planing on releasing one in 2018 but i can not find any anywhere.

thanks in advance for your help.
