The BD570's AV output selection is standard. The only surprise is the lack of analog multichannel outputs, which were available on last year's BD390.
|Ethernet||Yes||SD card slot||No|
|USB ports||1||RS-232 port||No|
Like virtually every other player, the BD570 also includes an Ethernet port if you prefer the stability of a wired connection. We would have liked to have seen an additional USB port on the back panel, like on the Sony BDP-S570 and Oppo BDP-80, but it's a minor quibble.
Blu-ray image quality
Overall, we were impressed with the BD570's Blu-ray image quality, as it passed all of the most important test patterns and program material tests. As usual, the most dedicated videophiles will still prefer the very slightly better Blu-ray image quality of the Oppo BDP-83, but the vast majority of high-definition movie fans will be perfectly satisfied with the BD570's Blu-ray image quality.
All our testing was conducted via HDMI at 1080p/60, with the Sony Bravia KDL-55XBR8 display and Oppo BDP-83 and Sony BDP-S570 for comparison. For more information on our testing procedure, consult our full guide to how we test Blu-ray players.

|Blu-ray image quality: Test patterns|
|Film resolution||Pass||Dynamic range high||Pass|
|Video resolution||Pass||Dynamic range low||Pass|
|Text overlay on film||Fail||Luma multiburst||Pass|
|Cadence tests||1/8||Chroma multiburst||Fail|
|Chroma bug test||Pass|
The BD570's performance on test patterns was largely solid. First off, it passed the two most important tests--the film and video resolution tests--that generally indicate the player will have no issues on the vast majority of Blu-ray titles. We did notice the BD570 slipped a bit on the film resolution test, showing moire for a second, which is something we didn't see on our reference Oppo BDP-83. However, we didn't notice any issues in actual program material.
The tests the BD570 failed--text overlay, the majority of the cadence tests and the chroma multiburst--are comparatively minor tests that don't have a major impact on image quality. In the text overlay test, while the text itself was free of artifacts, the video in the background suffered from comb-like shredding, visible on the top of the newspaper, and anytime one of the edges of any of the actors when they're in motion. However, the issue isn't visible with subtitles on standard Blu-ray movies like "Mission: Impossible III." Yes, the BD570 failed some of more esoteric cadence patterns, but we've seen almost no program material on Blu-ray using those cadences, so we don't consider that test very important.
The LG BD570 also failed the chroma multiburst, as the most detailed section of the test pattern was darker than the rest. However, we couldn't notice any difference resolution or color in actual program material, so it's hard to ascribe much to the BD570 failing this test. Videophiles may also be interested to know that the BD570 does clip whites in "standard" mode, but movie mode passes all "whiter-than-white" signals without a problem.
|Blu-ray image quality: Program material|
|Ghost Rider||Pass||Tony Bennett||Pass|
|M:I:III||Pass||NIN Live; chapter 3||Pass|
|Sunshine||Pass||NIN Live; chapter 4||Pass|
The BD570 passed all our Blu-ray program material tests, which gives it an edge over the competing Sony BDP-S570, which had some trouble with the video-based "Tony Bennett: American Classic" disc. However, the image quality difference between the two players isn't that large, as most movies are film-based and look nearly identical. We felt the difference between the BD570 and the Oppo BDP-83 was even smaller.
|Blu-ray operational speed (in seconds)|
|"M:I:III" | player on||13.69||"POTC" | until movie||83.57|
|"M:I:III" | player off | quick start||n/a||"Spider-Man 3" | until movie||67.72|
|"M:I:III" | player off | no quick start||23.92||"Sunshine" | chapter skip||13.71|
|"POTC" | past loading||30.24||CNET speed rating (composite score)||89|
(Longer bars indicate better performance)
The BD390 was one of the fastest Blu-ray players of 2009, but our testing indicates that it's likely to compare less favorably in 2010. The CNET speed rating of 89 means it's somewhat slower than last year's speed champ, the Oppo BDP-83. Some of its slowness is because it lacks a quick start mode, but it also took longer to load more complex movies like "Pirates of Caribbean: Curse of the Black Pearl." Its chapter skipping speed is comparable to most other players, but the competing BDP-S570 made us readjust our expectations with its lightning fast operation. The BD570 doesn't feel slow on its own, but when we had it side-by-side with the BDP-S570, it seems a little pokey.
There have been many reports online about playback problems on movies like "Up" and "Terminator: Salvation", and we've been able to confirm the issues on those movies, but only in 1080p/24 mode. Since the movies play fine in 1080p/60 mode and LG has stated it's working on a fix, we don't consider it a major issue, although we'll continue to monitor user feedback. For more information,.
|DVD image quality: test patterns and program material|
|Video resolution||Fail||"Star Trek: Insurrection"||Pass|
|Text overlay on film||Fail||"Invite Them Up"||Pass|
While the BD570 failed some of our standard test patterns, we didn't notice major issues in any of our program material tests. It's worth pointing out that while the BD570 did technically pass the 2:2 resolution test, it took much longer than the Oppo for its processing to kick in and eliminate the moirÃ©. Again, we'd give it a slight nod over the Sony BDP-S570 for doing a better job handling niche video content, and pure videophiles will prefer the Oppo BDP-83 if DVD image quality is a high priority.
|Streaming video image quality|
|Netflix | "Lost" | "Some Like it Hoth"||Good|
As with most devices, we saw no major issues with Netflix streaming on the BD570. That gives the BD570 an edge over the Sony BDP-S570, which suffers from some streaming image quality issues.
|Standby | quick start off||0.14 W||Standby | quick start on||n/a|
|Power on | watching movie||15.31 W||Power on | idling||14.79 W|
|Annual cost; quick start off||$1.07||Annual cost; quick start on||n/a|
Unlike many newer Blu-ray players, the BD570 lacks a quick start mode and therefore by default uses very little power in standby mode. In comparison, the Sony BDP-S570 has an annual cost of $7.35 with its quick start feature enabled. The downside with the BD570 is that you don't have the option of faster load times if you're willing to pay the extra cost.
