In-depth review of P50 with 4K display

I found this detailed review of the P50 with the 4k display and Xeon process posted on YouTube.

Re: In-depth review of P50 with 4K display

Really funny coincidence, I must have watched that video 15 minutes before you made this thread Smiley Happy

His Spyder 4 meter seems really off though. I measured a contrast ratio of about 1000:1 using my DTP94, while his is hovering around 600:1-700:1, and his measurements for brightness are about 60 nits lower than mine. The promised specs are 1000:1 and 300 nits.

So what's going on? Different panel revisions? His display doesn't seem to be dark in the rightmost area, but as it is covered by the task bar, it is hard to say for certain. During the gaming session it looks fine, though.

 

But he didn't sound impressed by the viewing angles. "I can live with it, given everything else is so nice about it". Sigh! Smiley Sad

Re: In-depth review of P50 with 4K display

The P50 4k panel looked fine to me, but it did appear that the central portion of the screen was a bit brighter than the sides. I don't think that you are going to find perfection in a panel made for a laptop. There are just so many compromises that have to be made compared with a panel that is to be used in a stand-alone monitor. How many 4K 15.4" panels have you personally viewed (or 17" panels for that matter)? These are specialized for laptops. When I search for 4k monitors, the only ones that I can find online are 27" and up. I wonder why?
