ViewSonic VG2455-2K 24 Inch IPS 1440p Monitor with USB C 3.1, HDMI, DisplayPort and 40 Degree Tilt Ergonomics for Home and Office

I bought this monitor specifically because it has an USB 3.1 C port, which would allow me to plug it directly into my IPad Pro 12.9 4th gen port. It played for a few moments then lost the signal. Then I saw that my USB-C port no longer worked, I could not charge my IPad, the port was dead. I called Apple and they made me an appointment at Best Buy. The tech there did a hard reset and it functioned again. His explanation was that the monitor was supplying an unacceptable current to the IPad. Apple has software that recognizes when this happen and shuts of the port to avoid damaging the tablet. A hard reset will bring the tablet’s port back to life. The tech said I should not use the monitor again. Also I could not use the buttons on the monitor to access the setup menu, all in all this thing was junk. Returned it to Amazon for a refund, no problem there at least. Amazon really stands behind whatever they sell.

I tried this out with two Macs, a 2018 MacBook Pro with USB C connectivity, and a 2015 MacBook Pro. I connected the ViewSonic using a USB-C to DisplayPort cable, using a Thunderbolt 3-USBC cable, and using an HDMI cable. Whichever cable was used, from whichever Mac, resulted in an identical HD picture and an instantaneous transition to two side-by-side windows that could be used from the Mac. The picture itself is larger than that of the MacBooks built-in video but not quite as bright or as crisp. Still, it makes for perfect watching from a distance - Netflix streaming - or for having an extra stretch of desktop for home-based office work. What I have not been able to make work is the audio. For both Macs, for any cable, I was at best able to get it so that low level volume comes through to the ViewSonics speakers but it is not menu-adjustable nor does it respond to the built-in volume control (though the mute setting works properly). This may be a problem on the MacOS side rather than on the ViewSonics side, The sound can easily be switched back to the Mac where it is controllable in the usual manner. There are a number of adjustments to the video that can be made from the ViewSonics built in menu-driven control structure. Input control to get where you need is reasonably intuitive. The angle and height of the monitor on the detachable stand is easily adjusted, and the unit can be used in portrait mode if desired (and thats really where this shines, since that makes review of long pdf files or Word documents a breeze). This is more of an expansion of the MacBook Pros built-in video for those who need more desktop space, rather than as a separate screen for watching movies or other streaming material. From that perspective, connectivity and operating functionality is all excellent. Now if I could get the audio to play nicely with my MBPs, Id be happier with alternative applications.

unfortunately NOT compatible with my Mac Mini Nov. 2018. After a few tries it stopped connectingvia the adapter to the USb-C port. Also it corrupted my external hard drive.

Updated Review: 5/5 stars ViewSonic customer support was great. They admitted there was a problem with firmware updating on MacOS and sent me a replacement monitor and a pre-paid shipping label to send mine back in the same box. The new monitor came with the newest firmware and it works flawlessly. They said that they would fix the bug that breaks monitors during firmware updating, but I still wont risk updating this monitor. Besides the firmware update issue, the only other complaint I have is that the speakers are useless; theyre completely flat and tinny. Other than that, the picture quality and the build quality are excellent. Original Review: 1/5 stars This monitor was great when I first got it. The image is bright and the colors are good. It charges my 15 MacBook Pro and gets 2K output at 60FPS and acts as a USB hub, all over a single (included) USB-C cable. The monitor stand is also very nice, it allows easy height, tilt and rotation adjustment and the setup took less than 5 minutes with no tools. However... I installed the VDisplay software (which lets you control some monitor settings from your computer) and noticed that the monitor had a firmware update available. My monitor was on M001 before the update. After the update, it went to M002, but my monitor could no longer display a proper image. Everything was horribly mangled and covered in rainbow static. Ive tried a laptop and an iPad, Ive tried USB-C and HDMI. Ive reset all monitor settings and tried changing color and display settings. Nothing fixed it. Now my monitor is completely worthless

long story short, I shouldve kept my previous LG monitor from Costco and just bought an external speaker. It would probably have been much cheaper. This monitor is neat for being adjustable.

Super happy with this monitor. USB C video and sound work perfectly with no additional software needed. Wonky controls can be frustrating at first but once you figure them out it is easy. Amazing value for the money.

The monitor is ok, nothing fancy. I purchased it because it was supposed to support pass-through charging for my MacBook Pro so I could cut down on the cords on my desk, after reading some of the other reviews and tech questions it sounded like the monitor would but that appears not to be the case. I even purchased a 3.1 USB-C cord but no luck. I dont think this thing puts out enough power sadly.

Overall this really is an outstanding monitor. Not the lowest cost, but not high either. The picture is crystal clear and that is the main thing. The stand is one of the best I have seen. Smaller footprint but sturdy and loaded with features. Also hats off to Viewsonic for the formed paper packaging instead of styrofoam. Very nice environmental touch and you deserve a star just for that. I hope that more companies go this route. There are a couple of issues I will list but mostly these are nitpiks. 1 - The finished side of the base faces the rear of the monitor. The less finished side faces the front. You will see this in any picture. The back facing of the base looks great but it really should be facing the front. 2 - The brightness needs to be turned up especially in a bright room. Not bad but it is a little dimmer naturally, so a higher brightness setting is needed. 3 - No Display Port cord. Personally I would rather it shipped with a DP cord than an HDMI cord, but that is me. It does come with the USB cord and USB - C cord, but that DP cord would have been a better option. I had to buy 2 for the dual monitor setup I use. Again these are really just nitpiks and nothing that would stop this monitor from receiving 5 stars.

To start, let me reiterate whats already been shared. This monitor will only work with a Mac laptop with a USB-C 3.1 connector. I originally tried using my USB-C charging cable that I use to power my laptop and that DOES NOT WORK. I went to the Apple Store to buy a Belkin USB-C 3.1 cable. I told the Apple Store clerk I needed this cable for use with a Monitor and they tried convince me I would need a Thunderbolt 3 USB-C cable instead. I ended up buying both and they both work, but I will be returning the Thunderbolt cable because it was $10 more expensive (And .2 meters shorter ). I should gone with my gut, now I have another errand to run. Just get the Belkin USB-C 3.1 and the monitor is plug and play! I am thoroughly impressed with the quality of this monitor, after adjusting the Color/Brightness/Contrast Ive got it matching my Mac laptop Retina display very nicely. I will say, the brightness on the laptop can go maaaybe a hair brighter than the monitor, but its barely noticeable. Also the sharpness on the monitor looks great, but its not quite as clear as the laptop. That means this probably isnt the best monitor for high end detailed Video/Graphic design work, but for everything else this monitor is excellent. The aspect ratio on the monitor is a little wider than the laptop so you have to deal with a tiny sliver of letterboxing on the laptop. (You can also opt for vertical letterboxing on the monitor, but this doesnt look as good). Other great features: The USB-C 3.1 cable will charge your laptop while also presenting the display. There are an additional 3 standard USB ports. Ive tested out the usb connections and the devices Ive tested have worked perfectly with my laptop. This is a great bonus. Also, the stand was so easy to set up. The monitor snaps into place and the base screws into the neck with a single flat head screw (But it has a twist handle so you dont even need a screw driver. The stand is heigh adjustable and also rotates about its vertical axis and tilts up and down. The best part is it also rotates about its depth axis so you can work on projects in Portrait rather than landscape orientation. Perfect for writing. The speakers on this thing are awful, but I cant imagine anyone would buy a monitor for audio quality. Grab a pair of external speakers and youll be set. Overall, this a great deal for a very good 1440p monitor with some useful additional features. I recommend it for use with a mac laptop for anything other than high end video/graphic work. For everyday use, its excellent.

This Viewsonic monitor is a terrific addition to any system. Large, bright, sharp, and clear picture. It’s easy to install, and works perfectly with my desktop. It’s also very reasonably priced for a monitor of this size and quality.
