Samsung CJ79 – Ascension and issues : ultrawidemasterrace
Replace Oct 15: TLDR: I made a decision to maintain the monitor, primarily as a result of I’ve discovered a workaround: this good little life-saver software allows HiDPI on MacOs for non-retina shows. Credit to the script creator!
I’ve already spent two days of attempting each single workaround on the market, with no luck. I is perhaps lacking one thing (I actually hope I’m), however I am virtually sure that “it’s what it’s”: VA – 1440p – 109DPI is just not adequate for textual content, or is it?
Okay so let me begin by saying I did my house work earlier than going for the CJ79.
My last choice was made primarily based on the marketed 1-cable Thuberbolt three connectivity, which I can say it really works out of the field: simply plug the supplied TB cable to appropriate port and voalá, you bought your self a full desktop setup. It’s also possible to join a few fundamental equipment (in my case, wi-fi mouse and keyboard).
Decision and excessive refresh price similar factor, no points. 3440×1440 @ 100hz, whereas charging the laptop computer. A dream come true up to now.
Viewing angles are as anticipated for a VA however I can say I anticipated worse, so I am very proud of it. The truth that the panel is aggressively curved (1500R) I imagine helps to keep away from coloration and distinction distortion in case you do not transfer from the middle of the display screen. I learn some evaluations from the trusted RTINGS.com guys, and so they gave a really low rating to the `viewing angles` class, however it’s comprehensible given the “workplace use case” the place a number of viewers sitting side-by-side attempt to learn from the identical curved display screen. For a single individual use case, viewing angles (with the assistance of the panel curvature) and virtually good.
Concerning coloration accuracy and distinction, I am neither an professional nor have the correct gear to measure, however I can say they’re within the “okay” class (I do not really feel is thoughts blowing , and I additionally imagine the panel may very well be brighter).
Now, I am about to return this unit and the explanations are:
– textual content / fonts are horrible, actually: I am is perhaps biased since I have been utilizing a setup with the MacBook Professional 15″ with retina and an exterior Samsung 32″ 4k 16:9 VA panel. Even after I’ve by no means had the 32″ in full 4k, scaling it to 1440p offers me good font rendering nonetheless sending 4k sign to the monitor. I assume which means I may by no means get the crispy fonts the scaled 4k (at ~ 138DPI) renders, compared with the native 1440p from the CJ79 at ~109DPI. By no means thought it will make such a distinction, however it does, fonts look terribly pixelated:

Firefox: Mail header in Gmail
MacOS System Data
MacOS: Shows setting window (picture taken with S20+)
That is like hell for me, since I am more often than not coding, studying pdf and textual content in browsers.
– 2nd Thunberbolt three port (the one which outputs 15W) cannot be used to increase aside from USB port for exterior drives (I wasn’t capable of join not even a easy usb keyboard, the identical I am completely utilizing linked to one of many USB 2.zero ports on the again of the monitor). I examined the port with a generic multi-port hub (I may solely use usb ports for charging or drives; curiously the ethernet port was obtainable) and a fundamental however nonetheless superb docking station from Plugable (on this case, similar factor as with the hub concerning the usb ports, and nothing else, not occasion the ethernet port, was populated to the host).
– the reference to the monitor is established with velocity as much as 20gbps (as you may see within the screenshot above): that is comprehensible if utilizing the supplied cable, since many people already mentioned it is really a 20gbp cable the one supplied by Samsung, however I’ve additionally examined with an authorized Intel Thunderbolt three cable, able to 100W PD and 40gbps
