This has been bugging me for a while now, windows 10, new motherboard, HDMI to 4k tv [600 nits], intel uhd on board display adapter running at 60hz, when I play a 1080p encoded video with, for example, Windows Movie and TV app, it plays fine, but when I play the same move or show in a 2160p encoded video it shows so much darker to the point of making it unwatchable. Pulled up the same show, one in 1080 the other in 2160 and took a screenshot, and am attaching it to this post. Does anyone have any idea why this is happening? The fact I can screenshot it and it looks darker in the screenshot seems to tell me it's not the fault of my TV, but I can't figure out for the life of me, what I would upgrade to allow the 2160p encoded videos to play as bright as the 1080p videos, I know I could mess with the brightness on either the display or the video app, but why should that be necessary (windows Movies and TV app does not have a adjustable brightness, but the "glamour" of the videos it plays beats any other video player out the door, by miles, if you know you know). Cheers.

Is there a way to access old IDE 40 pin harddrive with new pc components.
My plan is to connect the old HDD to my new b450 pro mainboard wich has USB, DIMM, PCIe and SATA.
Is there any adapter to connect it to my new PC? I have a lot of Pictures on it.
It also is the bootdrive, installed with Win XP Home.

Windows 10 on a HP Desktop PC Pavilion P7-1003W (QN574AAR#ABA) Athlon II X4 650 (3.2GHz) 8GB DDR3 (2 x 4 GB)

I have a four-bay USB hard drive enclosure which has only had one hard drive in it. This works in concert with 2 internal HDD (I use cubesoft's Drive Pool to ensure duplicated copies exist of all files within a JBOD). Then about 2 weeks ago I added a new hard drive to it to bring the total up to two. Everything worked fine until the last 5 days when I noticed unzipping. rar files over 1 gigabyte gave a "corrupted rar" error.

The immediate suspect is the new hard drive I added to the enclosure. My hypothesis was strengthened by the fact that the errors went away when I removed the drive from the drive pool. However, when I run the same file operations with the new drive as a standalone disc inside the enclosure, it works no problem.

With the second drive in the enclosure, it is probably writing to both discs simultaneously and I wonder if doubling the amount of traffic on the USB cord could cause trouble if the cord is bad, even though it doesn't cause problems when using one drive at a time?

I'm also going to try the drive in a different slot in the enclosure, however I need to wait a few hours for the HDD diagnostics I'm running to finish. I'll also run a memtest, although given I can remove the problem by removing the drive makes me wonder about the issue being with the USB / HDD enclosure systems or possibly the drive.

Any other suggestions? Thanks!
