LG 29EA93—Brightness and Contrast

The LG 29EA93 uses a totally different panel and backlighting setup than any display that I’ve tested, so for once I am coming into a review without any real idea of how something will perform. With the LED backlight set to maximum with a pure white screen, the peak brightness measures at 252 nits. This is a bit lower than I expect but fine for those people without direct sunlight on the screen. With the backlight at minimum that light output level drops down to 61 nits, which provides plenty of range for users that have light controlled environments and want a dimmer display.

White Level— XR Pro, Xrite i1D2 and XR i1DPro

Black levels on the LG are pretty good in comparison to other IPS panels. The black level with the backlight at minimum is a nice 0.237 nits, and that drops all the way down to 0.057 nits with the backlight at minimum. When measured against the peak light levels and against other IPS displays, these are good black levels to see.

These numbers combine to give us a contrast ratio over 1060 for both minimum and maximum backlight levels. This puts the LG up there with the best IPS contrast ratios we have measured on any size display. The best VA displays still perform better, but IPS has managed to really improve upon contrast ratios the past few years.

Overall the peak brightness left a bit to be desired on the LG 29EA93, but the black levels and contrast ratio help to make up for that. They still won’t make it a good choice for someone that has to deal with direct sunlight on the display, but for users without that you can get plenty of brightness and a good contrast ratio from it.

    People complaining from the 16:9 vs 16:10 or 16:10 vs 4:3 are not complaining just based on aspect ratio. Actually everyone would like a wider display and not complain... if it really were wider. Unfortunately manufacturers often accomplish these wider ratios by cutting out vertical space instead of by adding horizontal space.

    With this display we do have added horizontal space over a regular 1080p display. So I do not expect anyone to complain... Unless this is priced to compete with 2560x1600 displays instead of with 1080p displays, in which case, yea, it is a no-go.

    Price is quite disconnected the number of pixels.
    With this display being so uniform, it's reasonable to add a premium to the price.
    Additionally, there's a bit of exclusivity thing going on, with only two screeen manufacturers marketing that panel.

    I complain and I complain cause of the aspect ratio, my office desk doesn't have unlimited space, if I allocate 50cm for the screen then I'll lose screen area when I move from a 16:10 to a 16:9, on a 4:3 screen I could easily open a page on Office and see everything now I always have to scroll up and down same with web-pages, the ribbon thing on Office doesn't help either!

    I must agree with Visual.

    The complaint with the transition to 16:9 was not about the aspect ratio. Rather it was that the transition was accomplished by shrinking the height and thus the screen.

    Had the 16:9 panels been introduced at a resolution of 2133x1200, it's unlikely there would have been much complaining.

    These 21:9 panels are presented as an expansion of the existing standard; you're not losing display area unless you're transitioning from a 2560x1440 monitor which usually costs half-again as much.

    If 1080 is an acceptable vertical resolution for you, then this screen offers the opportunity to expand horizontal coverage (run a 16:9 game/movie window and keep other information visible) without using up all your desk space or dealing with two bezels right in the middle of your field of view.

    It's priced to compete with 27" 2560x1440 screens. This is 2560x1080. They chopped off some vertical resolution, they didn't add horizontal resolution. Reply

    " the film was more enjoyable when freed from black bars that distract from the film at hand. "

    Really? Black bars are distracting? Sounds like have ADHD or something.

    Then what are you going to do when the movie isn't in that specific ratio? Because plenty aren't. Goodness me, of all the complaints I've heard, that's a poor one.

    You would probably need to have OCD to really be bothered by it. I'm sure most with ADD or ADHD wouldn't be. You would need to have an actual anxiety related syndrome to be really bothered by it. Not raging out for loosing a match in CS in front of their computers.

    I guess you must have Tourrett syndrome for yelling out insults? Well it's the internet. So..

    There is a field and a small market out there for people who want something close to 2.35:1. There is plenty of content produced in anamorphic wide screen or within that 2.35-2.40 range. Is a matter of preference for some and obviously the reviewer didn't think it hit the mark with this one. It isn't unreasonable that it should work in it's intended aspect ratio. There is some interest in this kind of monitors. Obviously on a 2.37:1 screen like this it would be letterboxing all around a 2.35 film that isn't custom cropped. It would just be at the top and bottom on a 16:9/10 or 4:3/5:4 screen. Here it would also have bars on the sides giving you an much smaller effective viewing surface. Much worse so then a 1.85:1 or 16:9 movie. The real advantage is only there if you can crop the movie to fit the screen, otherwise 2:35:1 content is just unusable.

    What this is, effectively, is an attempt at CIH for direct-view displays. More and more projectors are beginning to adopt this feature or allow for CIH lenses (usually above the $2,500 mark), but the same problems exist there. You have to adjust for pillarboxing instead. I much prefer pillarboxing to letterboxing. Of course, with CIH projection, you never lose 1:1 mapping.

    The downside to all of this is that all 1080p films on Blu-ray are 1920x1080 resolution for the video streams including the black bars. So when you blow up a 2.35:1 image on a native XXXXx1080 display, you no longer have a true 1:1 resolution, so you need a high-quality scaler to avoid artifacts. ~1920x800 would be better suited to this, but obviously then you would lose resolution for 1080p 16x9 and 4x3 content.

    I really like the wider screen for gaming, but you can achieve the same horizontal resolution with a standard 30" monitor, but gain vertical res as well.

    I also am probably one of the targets for this monitor, as my home theater uses a 2.40, 122" screen, so I'm very familiar with all the reasons for anamorphic screens, as well as the issues that can arise in the setup of them. It's really about the choice of Constant Image Height over Constant Image Width, where both are going to have compromises for the viewer. For those that want a CIH setup, a 21:9 monitor offers something that is very expensive to do with a projector (a high-end anamorphic lens is thousands of dollars alone), but still has flaws of course.

    Too short and fat. These manufacturers and marketing managers are arrogant! Reply
