Client version will state the firmware revision #
I have a Sony (55X900A) and I have 4K set top box (VIP5662W) sw version 3.1.33566.453 and things have gotten worse with the new sw update. I no longer have the choice of 4k @ 24Hz. Now that that has disappeared as a choice, I am left with only 4K @ 60 hz that does not work at all, and 1080p which works, but that is not the quality I am paying for.
Is there any way to get 24Hz as a choice until they figure out the bug with 60Hz?
So here is what I have discovered at least as far as my 4K model Sony (KDL-55x900A). Model years 2013-2015 have the capability of only 4K at 24Hz. The new firmware upgrade has removed this aspect ratio as an option, leaving only 4K at 60hz. This is a format that is incompatible with this model tv as a handshake will never occur because of the higher demand for refresh.
My hope is that TELUS returns the option for 4K @ 24 Hz to the aspect ratio menu selection as this would appear to be the only "fix" for my particular issue. It may not be ideal, but it is the only way to get the 4K for may to Sony pioneers (those that bought early models).
Please TELUS... re add the 4K @ 24Hz option to the aspect ratio for the "pioneers"
