HP EliteDisplay E271i Review: Solid Performance From A 27" Screen

Results: Viewing Angle And Uniformity

For off-axis viewing, there’s no better tech right now than IPS. You can sit as much as 45 degrees from center and still see a decent image. The light falloff is minimal and the color shift associated with TN monitors is virtually non-existent. In addition, with a monitor as bright as this, the effect can be further minimized at high output settings.

The HP looks like every other 27-inch IPS monitor we’ve tested: excellent. You can still see all the detail in the highest and lowest portions of the ramp pattern and there is no color shift as you move up to 45 degrees from the center axis position in any direction. If the monitor you’re reading this on is set correctly, you will see 11 bars in all five viewing angle photos.

To measure screen uniformity, zero percent and 100 percent full-field patterns are used, and nine points are sampled. In a change from previous reviews, we’re now comparing the results to other monitors we’ve measured. First, we establish a baseline measurement at the center of each screen. Then the surrounding eight points are measured and their values expressed as a percentage of the baseline, either above or below. This number gets averaged. It is important to remember that we test a single sample only, and that other samples of the same monitor can measure differently in this metric.

First up is black field uniformity:

Since the HP’s black level is so low, we had to take many readings to get usable numbers. For each point on the screen, we took 10 measurements and averaged the result. Yes, that’s 90 measurements! With a low 4.83 percent average deviation, you won’t see any dark or light areas in a black field. This is excellent performance.

Here’s the white field measurement:

The white field value of 7.5 percent isn’t quite as good as the black field number, but it’s still practically imperceptible. If you stare at the screen long enough, you’ll see a little light falloff in the upper-right portion of the panel. You won't see it in any normal image content, though. Again, this is excellent performance. While IPS is generally the best choice for good uniformity, all types of LCD technology have made huge improvements in this area.

Screen Uniformity: Color

Starting with our last monitor review, AOC’s Q2963PM, we’re adding a new uniformity test to our benchmark suite: color. The above measurements only address luminance. Now we’re measuring the white balance variation in an 80-percent white field pattern. The results are expressed as a variation in Delta E (in other words, the difference between the highest and lowest value).

Unfortunately, we only have these two monitors in the database at present. The E271i is especially good, with only a .34 variation in Delta E. Meanwhile, the AOC ranges from a high of 2.6 to a low of .48, which you still wouldn't pick up with a casual glance. Only our i1Pro knows the truth.

    I'd like to see what the difference in the actual manufacturing costs/panel prices are for QHD vs FHD for large screens - pixel density is certainly not a problem.

    I'd guess it's merely a chicken/egg issue - people won't buy high-res screens until they are cheap and they won't be cheap until lots of people buy them.

    That is the beauty of Capitalism. The rich have more than enough money, and will be more likely to spend money on something new. Companies wanting to maximize profits, try and make production cheaper. When company X makes production cheaper than company Y, then Y undercuts X and yay cheaper products.

    I wonder if they will come out with a similar IPS 23-24" monitor, I find that is the perfect size for me.

    Honestly from what I can tell this display is worth the money you pay. I might just have to pick up two of these and see what I can't do with them.

    meh, meh, meh, meh, meh. Toms, please leave these bland, generic products on the shelves of staples and office max where they belong. There is NOTHING impressive, interesting, or even noteworthy about a 27" 1920x1080 monitor today. I don't care if it makes gremlins when wet. At that resolution and size, it's just not going to be a good looking screen. Reading text on 27" 1920x1080 monitors SUCKS.

    Aside from the fact that compared to the QHD monitors you can pick up for under $300 this is garbage, it's just a silly format. Dated resolution on a cheap panel that's too big.

    I have 3 2560x1440 Overlord Tempests. Would NEVER use a 1080 panel again - especially an IPS. And TN panels? Forget it - IPS is so pretty at 1440.

    I understand where you are come from bot not every is looking for an extreme like that. If I had one of those I wouldn't complain. The monitor I currently have is better than this one, but that doesn't mean I wouldn't use this monitor. Tom's I believe is just trying to cater to everyone they can. So i say this kind of review is good for everyone.

    This is a massive 27 inch monster sitting with in 12-18 inches of your face while sitting at a desk.

    Why on earth would anyone want 1920x1080 on a screen 27 inches diagonal? Are you looking for pot holes between the pixels?

    The reason I say this is, I work with media all day, We currently create, edit and produce 4k video and store it for transfer to quad layer blu-ray disc's (200GB).

    Also, if you use any digital camera over 8MP, you will get close to a 1:1 pixel ratio at 4K resolutions.

    We want to see a continuous image and seeing the gaps between the pixels is distracting.

    24 inch monitors should have a minimum 4k pixel resolution, 708 might be able to get away with 4k on a 27 inch, but 8k would be better.

    Now, lets look at the other side, How much would a 24 inch 1920x1080 flat trinitron cost you back in the day? $6,000 ? $12,000?

    They should review QHD monitors. Not this crap.
