Rumors of a high-resolution Samsung Galaxy Note 5 with an impressive 4K display are surfacing again, anticipating an official debut in September.

Word of a 4K Samsung Galaxy Note 5 phablet first surfaced back in January of this year, and a new report now bolsters such claims while also adding some more information.

More specifically, Phone Arena reveals that the upcoming Samsung Galaxy Note 5 will rock an Ultra HD display with a whopping resolution of 3840 x 2160 pixels, which would make it the highest-resolution smartphone yet.

"We received a word that Samsung will be putting those UHD Super AMOLED panels in none other than the Galaxy Note 5, and will start the displays' production in August, which would jibe with an eventual September announcement around the IFA 2015 expo," Phone Arena notes in a new report on Thursday, April 9. "The exact diagonals are said to be 5.78" for the inevitable dual edge Note 5, and 5.89 inches for the regular, flat display version. These return exactly 762ppi and 748ppi, respectively, or the highest pixel densities ever attempted on a phone, if this Note 5 speculation pans out. The more, the merrier."

Samsung had previously reckoned that it is indeed working on a new 4K display for smartphones and it should hit the market this year, so this new report sounds plausible.

In addition to the impressive 4K resolution display, the Samsung Galaxy Note 5 may also pack the company's new Exynos 7420 processor that's currently powering the new Galaxy S6 and Galaxy S6 Edge smartphone. Moreover, the Galaxy Note 5 could also boast 4GB of RAM.

As Phone Arena notes, the next-generation Samsung Galaxy Note 5 and Galaxy Note 5 Edge are expected to go into mass production in August and make their official debut in September this year.

No other details are available at this point, but more information will surely surface in the months to come. As always, it's highly recommended to take all leaks, rumors and reports with a hefty grain of salt until a formal announcement. The next-generation Galaxy Note phablets are still months away, and we'll keep you up to date as soon as we learn more.
