I have about six CSV1474. However, the output of 4K 60HZ is not at all, and LG TV, monitor, and Samsung TV all have flicker symptoms. You can’t change all the settings. The FHD output is output without a problem, but only 4K 30P and 4K 60P problems. No newer drivers, no older drivers. The e-mail is [email protected] and if you have a solution, please reply.
