Monitor Color Shift Issue

I just bought a refurbished BenQ SW320 and set it up today. Unfortunately it has a very slight pink / red hue on the right side of the screen, almost like a very slight graduated filter. It's very slight but I noticed it right away. Maybe this is the reason it was returned in the first place, because it appears brand new besides that. Is there a way to fix this, or should I just send it back?

In the days of CRT, the electron guns for the three colors were magnetically aimed by shifting magnets, if when not aligned properly (or when magnetic disturbances caused variances from one corner to the other) one could get color shifts in different areas of the screen. Degaussing the CRT with a magnetic degausser would often fix color discontinuities across the screen, such as after moving the TV to a different orientation in the room. Later, TVs often automatically degaussed themselves.

In the days of LED monitors (or LCD monitors) there is no magnetic aiming of electron guns...there is only switching on/off each sensel of the 3-color triad (R-G-B) with solid state 'switching' done electronically.
I would send back the bad monitor that is color shifted differently at different places on the screen. I would ADJUST a monitor which is UNIFORMLY color shifted.

Thanks. It is not uniform. It's obviously more red on the right side of the screen. I can't see the shift with my naked eyes while editing or looking at a colorful screen, but on gray and white you can see the shift.

Another vote here for sending it back.

Yea that was never out of the question if it couldn't be fixed. While packing it up and sending it back will be tedious, I expect a $1000+ monitor to not have these issues, so I'll send it back for a refund or exchange.

Just looked at customer reviews at amazon.com and see things like this

"major issue on day 1
April 27, 2017
Size: 32"|Style: 3840 x 2160|Verified Purchase

For such high price this monitor doesn't meet my expectation. On the day it arrives, the brightness and color between left and right side already has obvious difference. The picture doesn't show much of the brightness difference, but you can tell the color tint on both side."

"September 13, 2017

Well
This is our second sw320 monitor in a week

We bought the sw320 expecting a problem free product invoking the quality that the description professes. We have had benq monitors before, and liked the products
The sw320 has a solid professional build and feels like a well made product
However :
Unfortunately both monitors came in with severe light bleed in the corners, dead or stuck pixels, and the manifestation of the light bleed was so bad that all the colors in the corners are bleached and washed out.
We do not wish to spend anymore money on a third attempt, with two in a row we feel the next will have the same issues"

"Horrible product that fails at the very thing it promises.

Got four monitors from Amazon and all four had a magenta hue on the right side of the screen. One also had bad light bleed. However the manufacturer said this is not a known issue with this model, attributing the issue with a potential bad batch.
Amazon was of course amazing with replacing the monitor each time with advance replacement options; UPS picked up the packages from house.
Atm I am monitorless as my work relies heavily on accurate color displays and my workflow was built upon the use of 4k at 10bit. Still hoping to get a working unit directly from BenQ.
UPDATE 11/16/17
DO NOT BUY THIS GARBAGE.
Just got another one directly from Benq. The left side of the monitor has a magenta tint. Benq, stop selling this monitor for color critical work if you can't display colors properly in the first place! What is the point of the 10bit panel and the 99% AdobeRGB if you can't fix the tint problem? Benq refuses to acknowledge the problem despite most of the critical reviews reporting this same issue. Apparently benq didn't read those reviews or heard the complaints because because according to them this is not a known issue.
This issue cannot be fixed with calibration. Don't get your hopes up people this monitor was too good to be true at this price. Will be getting a monitor from a more reputable company that actually cares about color accuracy. Obviously will be getting a lower resolution monitor because they cost almost 3x as much. But again don't try to save money by buying this because if you can justify keeping the color problem for the lower cost then you really don't need a color accurate monitor in the first place."

"Disappointed with the SW2700PT
January 7, 2017
Size: 27"|Style: 2560 x 1440|Verified Purchase

The reviews everywhere for the SW2700PT are favorable (including here on Amazon) and it seemed like a solid choice for my new monitor. On paper, this is the 27" QHD IPS monitor to beat for an entry level photography model, $599 is an outstanding deal in comparison to the $1000 starting price point for everything else with good reviews. Colors popped as expected and backlight bleed/IPS glow is minimal (barely noticeable). It has a striking industrial design and the wired puck remote control to adjust settings is a nice touch. Also, this thing is built like a tank, very heavy/sturdy construction. I confess, I really wanted to like the SW2700PT - I had a BenQ monitor many years ago that I really liked.

I tried two of these and wound up returning both due to screen uniformity issues with light/white backgrounds. I tend to split my screen into left and right hand applications (Photoshop and browser mostly). The first monitor had a 7" wide x 5" tall, kidney shaped "hot spot" on the right hand side of the screen where light/white backgrounds were much warmer then the rest of the screen, it started mid way down the screen and went almost to the bottom of the screen. The second monitor had two smaller "hot spots" on the left hand side of the screen, again with light/white backgrounds - one near the upper left corner and another starting mid-way down the screen going towards the bottom. Perhaps these monitors are better suited for true dark room work with hood attached and the brightness cranked way down OR I happened to receive two duds. Either way, I can't justify the purchase.

Granted these are not the majority of experiences, but they do illustrate that your refurb monitor issue is not a unique experience

Send it back, there is nothing you can do to fix it. Either the whole panel, or the whole back light needs to be replaced.

There are some firmware updates, driver updates, etc. so perhaps an hours time making sure everything is up to date would be worthwhile. See https://www.benq.com …w320/software-driver.html.

Nope, none of those will change what is build quality/hardware issue.
I've seen this on lots of monitors, from different manufacturers, and the only fix is to send them back and ask for another one.

Having uniform color and brightness across the monitor is one of the major quality control issues of current computer monitors. Firmware can't correct a defect in the monitor (though manufacturers have varying amounts of tolerance as to the amount of shift that can happen throughout the monitor). Interesting note with TV reviews: they also indicate that larger, more expensive, TV sizes tend to have more color shift (now 65 or 85") then smaller 55" versions of the same models.
