False advertising - no IPS display
938823
I don't typically write reviews, but as soon as I booted the laptop for the first time, I was taken aback by how terrible the screen looked, despite being advertised as an IPS screen. Immediately did a viewing angle test, and the pixels inverted like in a low-quality TN screen. Opened the control panel, checked the monitor hardware ID, and of course it turned out to not be IPS. Extremely disappointed--will be returning it. If you want a laptop with a good screen, stay away from this one.

Item is described as "PORT REP FOR CF52 A-B-C-D--E-F-G-H MK1 & MK 2" yet it is only *partially* compatible with models "A-B-C-D".  Product description did not state that it was not fully compatible.  The display port is not functional with "A-B-C-D" models so you cannot connect dual external monitors.  Other than that it seems to work as described.  Since I bought it for dual external monitors I am stuck with it. Of course I didn't know this until I opened the package and read the fine print in the owners manual so I cannot return the item. $200 mistake.

What I got was NOT what was pictured. The display does work, but it's nothing more than a small circuit board and display. There is no black case, there is zero wires coming off of it. There are 2 small pins for power. There is no separate voltage wire as described (which I really needed for my install). The display is hard to read as it is not behind smoked glass as pictured. The temperature probe is not remote, it's on a small 1 inch wire.

Product is falsely advertised. There is ZERO mention of load balancing in any of the documentation for this device.

One of the four so-called WAN ports is reserved for ISDN VoIP service, while another "WAN" port is reserved to be the management interface, and another one of the "WAN" interfaces is an SFP port, so it doesn't interface with 99% of the ISP handoffs out there. So that makes 3 out of 4 interfaces useless for plugging in connections from multiple ISPs.

Oh, and this unit was advertised to have a web-based GUI for easy configuration. Firstly, you can't just plug it in and begin to manage it over your network, you've got to connect via console cable (you'll need a 3rd party USB adapter to even do this, if you don't have an old-school console port from the 90s). Once you finally get connected through a 3rd-party console program like PuTTy and run through the initial text-based set up, you can then have the fun task of figuring out how to assign an IP address to one of your FE WAN port for management. Then figure out how to actually enable the web GUI interface. Finally, after all that, you can access the web GUI, which is the biggest disappointment you'll ever see. Look at the attached picture. Seriously, this is it. This would actually be funny if it weren't so sad. You can't actually manage anything from here, only monitor certain things.

This is only a review for people who are intending on buying this as an external monitor for a Macbook PRO or Air.

This particular monitor will give you horrible resolution on a Macbook Pro/Air because it does NOT have a Display Port input like the description says. It only has two HDMI inputs. Why does this matter?

The max resolution on this monitor is 2560 x 1080. However, it can only supply that resolution if the Macbook is connected to it via a Display Port input. Some Macbook's are handicapped with HDMI inputs where they only put out 1080i resolution which looks horrendous on this screen. Since this screen is falsely advertised as having Display Port, you may be tricked into buying it. But it absolutely does not have Display Port capability!

Cheesy Java utility to configure IP connectivity that is essentially useless. No external alarm silencer. Over-priced.

Dell should be held liable for ignorance in promoting this product with their laptops. This piece of equipment is not capable of handling audio/video, two important features for any user along with other features as promised.  The support staff, although trying to be helpful, have no clues as to the problems this product creates for users.  I wish there was alternative product that worked??  I'm also very disappointed in Dell and Targus's inability to acknowledge this products shortfalls and wish I could have back the multiple hours I've spent trying to get it to work via their tech support.

The product is falsely advertised (note the multiple negative reviews, many of which are IT professionals) and Targus should provide full refunds and pull it off the shelf until bugs are fully resolved and the staff understands how to diagnose.

I ordered this for my employer to use on a Plantronics CS530 headset with a VVX 500 IP Phone. Upon arrival of the package, I attempted to install this in conjunction with the 2 products above. On initial installation, All I received was "snow" from the phone, I went through all troubleshooting steps and contacted Plantronics Support and followed their troubleshooting instructions. I was informed that the cable was bad and to return it. At $55 + per cable, I would expect that the device would work as advertised and intended.

I did contact Plantronics and verified this is the cable for use for both the headset and the IP Phone, despite their website displaying incorrect information.

It was sold by Excellent Products Inc.

Hi, Please don't buy if you have any device that is Linux based, ie phone, Xbox, computer etc.  First check out the netgear forum for problems with v5 in particular (currently shipping) the DG834G v5 has a common problem where it will not give out a IP address (hardcoded or otherwise) to a Linux based device (wireless or cable).  Support says they will not support Linux at all so you can't return it because they will not admit there is a problem or work with you to try to identify if there is a problem or not just will not talk to you at all.  Horrible support, horrible product.  Completely unusable.

I found out about the fast one LG pulled on me after my 30 day return had expired. My serial number didn't have a "W" or a "D" in it; but I received the inferior VA scanning instead of the better IPS scanning some units were shipped with. This can be determined by using a magnifying glass and mine shows the square pixels instead of the triangular. I would have returned it if my 30 days had not ran out.

I didn't win the IPS lottery.

Amazon is still #1 with me; but I doubt I would ever buy another LG product.

Pay the extra money and buy a Samsung!

Absolutely non standard parallel interface with terrible support and no documentation. Save yourself the headache and get something with i2c or spi.  This screen is cheap for a reason, its crap built on obsolete surplus junk.

False Advertising.... I received the replacement kit, but the screen was a counterfeit, copy, pirate(d) copy, sham, fraud, hoax, imitation, mock-up....

The screen had no mount points.

As far as portable 15.6-inchers go, this one's not bad. However, you are being deceived.

This laptop advertises a screen resolution of 4K UHD 3840x2160, but that isn't a complete truth. It's using what's called the RG/BW Pentile matrix, a cheap trick to achieve the ability to advertise as 3840x2160, without actually achieving the full detail of the resolution itself. You can do a web search on this type of display to learn all you'd like, but without getting too technical here, it basically means even though the screen makes your computer render this resolution, you don't get to see all that detail on your screen, because it's missing half of its pixels.

Lots of reviews talk about how nice the display is. The reason for that is because many people buying new laptops today will have had old laptops with the old standard 1366x768 TN displays. This is a huge upgrade from those, but so are all the normal 1080p IPS displays you can get in other laptops half this price. Real 4K UHD 3840x2160 resolution is a huge upgrade from THIS display, and it is a disrespect to laptops that do truly achieve the resolution, that this one gets to advertise right along side them. It's not close to the tier of real-4K displays, and not even as good as the 3K 2880x1620 displays available in some laptops, such as the older ASUS UX51vz.

In my opinion, you should not buy this laptop. The Dell XPS 15 and Lenovo Y700 UHD both offer the same GPU, but have a real 3840x2160 display. The ASUS may have more RAM or a bigger SSD, but those should be low priority in your decision process because they can be easily installed after-market, whereas you're pretty much stuck with this display. The Dell XPS 15 and Lenovo Y700 UHD are truly worthy choices, whereas the ASUS UX501 thrives on deception. Don't buy it.

I have attached two images to this review. One is a closeup of the Dell XPS 15's display, and one is a closeup of a false-4K display such as the one in this laptop. Notice how only every other pixel can contribute to each primary color.

Arrived promptly well package and with no dead pixels.

I made the mistake of assuming I could connect this monitor to my HDMI/Displayport only computer using a HDMI to DVI dual link converter. I could never get it to work past the 1280x600 resolution in my linux setup. Hopefully someone can help. Never buying a DVI-D only monitor no matter how cheap it is.

The power supply is a big fat brick and the monitor makes a very slight buzzing sound. There are 7 buttons which unfortunately, four of them I have no clue how or what they are for since there is no english manual.

Looks great but Can't find the cam IP address  yet, Tried installing program with 2 PC's. Nervous about all the changes the program makes on a Windows  Box.  all eithernet links good. Wont respond to pings on same subnet.  No MAC support or simple Browser support. hopefully it's the unit.  will have to order another to see if it's a Bill Gates or hardware problem.  Have installed many other brands of IP cam's without the complexity of a windows box. sigh .. Wish it had 24V passive POE. ..

Monitor is quite good for the price but be aware you WILL NOT get the the ASUS $20 off promotion unless you buy another ASUS item.
Deceitful advertising.
