The 55” LG 55EG9100 OLED display is the entry-level LG OLED for 2015. For plasma fans, OLED has been billed as the great savior. Not only would an OLED be thinner than our plasma sets, but it could be brighter and have pure blacks. We wouldn’t have to live with the LCD compromises of worse off-axis viewing and backlights that can’t deliver the darkest blacks. OLED promises the potential to make us forget about plasma once and for all.

Having spent time with the LG 55EG9100, I can say it is the first display I might give up my Panasonic VT60 for. The blacks are pure and provide you contrast ratios no LCD can touch. The colors are vibrant and accurate while still looking great off-axis. Even the curve, which I typically dislike, is not as much of an issue. There are a couple quirks that hold the LG back, no set is perfect, but for those that miss plasma you might finally have the replacement TV you are after.

Amazingly Thin

As used to thin LCD TVs as I am, the LG 55EG9100 OLED is a looker. The top half of the display is as thin as you can get today. The lower half is larger to provide room for inputs and outputs, but still so thin it needs a captive power cable. Even mounting it on the included stand is strange as an OLED is too thin for the type of stands I usually see on a TV. Even at 55” the LG is light enough to do the unboxing and setup myself, though I do recommend a friend to help reduce the stress.

The included remote works as an on-screen pointer for the updated WebOS 2.0 interface. I’ve adapted to using an on-screen cursor instead of a directional pad, and the LG one is good enough. But the remote isn’t backlit which is surprising for a $2,000 TV. There are also only 3 HDMI ports on the left side. If you use a receiver this might be enough, but 4 or 5 inputs seems more appropriate for a high-end TV like this. These are minor quibbles with the set, and I was able to use the remote in the dark without issue after a day.

Perfect Black

Unlike an LCD, OLED pixels produce their own light. With an LCD the panel produces the colors and then a backlight shines through that to create the image. Creating black means closing a pixel on the LCD but some of the backlight always creeps through. Local dimming systems try to improve this on an LCD but those can create their own issues with blooming and other artifacts. Since each pixel on an OLED produces its own light, when you turn one off there is actually no light at all.

If you bought a plasma from Samsung or Panasonic the final year they were made, you have good black levels. So good that you can get a contrast ratio of 25,000:1 and have an image that pops off the screen. So what difference does going from very dark to pure black make? More than you can imagine without seeing it.

Watching scenes from Skyfall the scenes of Shanghai and Macau jump off the screen more than before. The night sky is a pure pitch black that both neon lights and fireworks stand out against. Even with these dark blacks, bright scenes maintain a fantastic, natural look. Skin tones are accurate without any hint of redness to them. The ocean is a rich deep blue while a helicopter exploding fills the room with light but doesn’t cause the night sky to shift from blackness at all. During a vertical pan there is some judder that is visible, but usually it cannot be noticed.

Jurassic World presents a lush world of greens and blues. Daytime scenes are plenty bright with lots of panel brightness to spare. The real flaw with the LG is that it makes the CGI of the dinosaurs more apparent. The struggle here is to come up with something that doesn’t look fantastic while watching the movie.

The usual Harry Potter torture test reveals one of the flaws in the LG 55EG9100. As Voldemort and his minions gather on top of the hill, the entire scene is near pitch black. The LG dips into pure black here, but dips too far. The dark shadow details around the edges of the screen are crushed down to pure black, losing those details. Turning the brightness up lets these details appear, but also moves the letterbox bars away from black into dark gray. Switching the gamma preset from 2.4 or BT.1886 to 2.2 or 1.9 also reduces this but doesn’t look as good overall in a dark room. This only seemed to happen to areas near the edges of the screen, and only with dark shadow areas but it was something I could notice.

Below you see three images taken at BT.1886, 2.2, and 1.9 gamma settings. You can see the right side descends into complete blackness instead of being a shadow. One click higher on the Brightness control and the letterbox bars would move out of pure black, so that isn’t the issue. It just seems to be a flaw in the image processing on the LG OLED displays right now.

While I usually hate the curve on a TV, it didn’t bother me with the LG. Since the viewing angles on the OLED are so much better than an LCD you can sit to the side without the curve reducing that viewing angle. Since the letterbox bars are black, the distortion a curve can introduce is much harder to notice. While I still prefer a flat display the LG is the first curved display that I was OK with being curved.

The fast action of sports looks great on OLED as well. Watching the NFL on CBS over-the-air there is no motion blur that I can see. 1080i test patterns reveal some small processing issues, but these are not visible when watching regular 1080i content on the screen. Combined with the wide viewing angle that the LG offers, it makes a good TV to watch when you have a crowd over to see the game.

As with most LG TVs the 55EG9100 uses passive 3D glasses instead of active ones. The largest benefit is that it is far easier on the eyes to watch with passive glasses than with active ones in my experience. The tradeoff with a 1080p display is that passive glasses cut the effective resolution in half. Watching Hugo in 3D the opening scenes show very good depth and very little crosstalk. The 55″ size doesn’t give you the most immersive experience but you do get a feeling of depth without much eye strain. Switching to Monsters, Inc the loss of resolution is noticeable on the fine fur of Sully. Moving back to 8-9′ away the loss of resolution isn’t at noticeable, but when you get close you can tell. Live action doesn’t show the aliasing as much but CGI is more impacted.

For streaming the included WebOS smart apps get the job done. Netflix and Amazon content streams quickly and reliably while looking good. It takes a little bit of time to start up but after that the responsiveness is good. It doesn’t have the selection of a Roku but it offers the essentials and does a good job with them.

Writing about the performance of the LG 55EG9100 is a challenge. Writing 1,500 words that just point out how incredible something looks over-and-over seems redundant, but it is what I want to do. The LG isn’t perfect, most notably because of the shadow detail issue, but it comes closer than any TV I’ve watched the past few years. It is a picture you have to go see in person because the improvement it offers can’t be conveyed in words.

Bench Tests

Pre- and Post-Calibration numbers for the LG EG9100 are nearly perfect. If you place it into the ISF Expert mode and set the primary controls, like Brightness and Contrast, correctly you will be rewarded with a fantastic image. Full details of the calibration with charts and data can be found after the summary or by following this link.

My First Choice

The LG 55EG9100 is the first display I’d consider replacing my Panasonic VT60 with. It has better blacks, is much easier to move around, and has much better SmartTV features. The shadow detail bug is an issue but to me that’s a much lesser problem than the ones that all backlit LCDs have. The accurate colors and grayscale along with a uniform panel make it an image that is hard to beat.

If I was shopping for a TV now and I could afford it, my list would start with the LG 55EG9100. The only display I’d consider instead for myself is the 4K LG 55EF9600. If you want something for less money I recommend the Vizio M. It won’t have the perfect blacks of an OLED but is an UltraHD display. If you want to be future-proof, you can step up to the UltraHD and HDR-ready 55EF9600 OLED for $1,000 more. If you want the best looking image you can get for $2,000, you should get the LG 55EG9100 as I would today.
