Is this a windows, Sony or LG issue? Cant get proper resolution on TV
I've been using an old Acer laptop conntected to a Sony STR 1050 receiver to an HD Plasma TV. The resolution was always set to 1920x1080.
Recently I upgraded to a 4k OLED TV and had some unusual difficulties getting the system to work properly. Initially, the Acer computer stated the optimal resolution for the 4k TV was 800x600. Still, I had it set to 1920x1080. However, when I tried to go higher, the TV screen blanked for several seconds before the computer reverted back to old res. Somewhere in the trial and error of settings, the computer defaulted to a 1920x1080 recommended setting.
I then plugged in my newer HP OMEN laptop and it did allow to set it 4k successfully, even though it stated that the recommended resolution was 1920x1080. So I concluded that my old Acer just wasn't up to the task. But then I plugged it directly into an HDMI port on the 4k TV. Both laptops recommended 4k (38xx x 21xx or whatever it is), so that told me that both laptops are capable of the 4k output.
I then fiddled with the receiver's settings. I noticed there was a 4k upscaling option that was turned off so I set it to 'Auto'. The only difference I discovered was that the Omen laptop now said the recomended resolution for the TV was something like 462x352! I did notice something else but cannot recall when I first observed it: The TV prompted me at one point to allow for "HDMI Depp Color" and the options were 'off' and '4k'. It seems that when the 4k is set to ON, thats when the laptops' recommended resolution is 600x800 and when it is off, it recommends 1920x1080. There is also a 4:4:4 passthrough option on the TV.
I've checked the HDMI cables to make sure they were high speed.
I cannot figure out why the resolution is not recommended to be 4k when running through the receiver and why I cannot set it to 4k with only the one laptop.
Any thoughts?
