LG 29EA93 Monitor Review - Rev. 1.25
by Chris Heinonen on February 12, 2013 8:49 PM ESTWith the 29EA93 being targeted towards gamers, where it can offer a wider field-of-view for games in comparison to standard 16:9 monitors, the poor lag performance of the original model was a big issue. Serious gamers would not put up with that, and so it was not connecting with its target market. With the new revision, lag is virtually non-existant. With the caveat of having to test at 1920x1080 instead of 2560x1080 due to CRT limitations, the LG exhibited 1ms of input lag with my testing. Previously we saw 27ms of input lag, so this is a completely different level of performance. Testing with the HDMI input and not the DVI input led to the same results.
Disabling the game mode only introduced another 1-2ms of lag, but at the expense of image quality, so I would leave it disabled. The total lag from input and pixel response was between 9 and 15ms. I say between because the LG 29EA93 appears to have a scanning backlight that doesn’t match-up perfectly to the refresh rate. Because of these different blanking intervals, the refresh rate of pixels can change slightly, so there is a range of response times instead of constant ones.
I also tested lag using a lag tester from Leobodnar.com, which uses an HDMI output and runs at 1080p resolution. Using a photo sensor it flashes a pattern on the screen and then senses the flash, then updates the screen to have the total lag time. Using this device I got the same results as with SMTT, between 9.6 and 15.8 ms of lag. The downside of this method is there isn’t a separate input and pixel lag time test, but it works much faster and seems to be highly accurate in my testing of it. Unless there is significant feedback about SMTT being superior to this, it might be the method I use in the future.
Due to interest, here are some screenshots showing the difference between 1920x1080 and 2560x1080 in games. I will attempt to add some more before returning the display.
Compared to the previous version, power use is 2 watts higher with both maximum and minimum backlight. That's close enough to be simple variance between units, so we won't worry about it.

No there is no way of knowing. i'll buy this monitor 6 months from now just to be sure.sant2468 - Friday, April 12, 2013 - link
To get the service menu up, first switch off the monitor, then while holding down the menu key simultaneously press and hold the power button, keep holding both buttons until the monitor powers up then release them. Press the menu button once and up pops the menu. To revert back to the OSD menu, turn the monitor off then back on again.Ubercake - Wednesday, April 17, 2013 - link
If they can get this to operate at 120Hz, I'd buy it tomorrow.sant2468 - Friday, April 19, 2013 - link
i have to say. i went for the dell version and it clocks to 75 hz. haven't tried to overclock this any further and it runs so sweat.All games run very nice at 75 fps.

I asked dustinhome if they knew what revision they had for sale. Got this answer: " ...there is new firmwares released now and then. And there shouldn’t be any other difference than the firmware between these revisions, if there is something wrong with the firmware in a product then the customer can contact LG and they will decide if a firmware upgrade can solve the problem. For this product it isn’t possible to upgrade the firmware as a user, it needs to be done by LG Service. And we don’t get any information about which revision we get delivered, since it is delivered on the same part number."Big_Lund! - Monday, April 29, 2013 - link
Just bought a LG 29EA93-P from Fry's this week (San Jose CA). Mgr date is Feb 13 2013 Rev-01 which is version 1.25. The way to verify is to Hold the power & Menu button's together and you will see the version number on the top left corner! Once calibrated the best monitor to date! Great for games, movies & editing photos.noknowsu - Wednesday, May 22, 2013 - link

Thanks anandtech!!MacDavePro - Thursday, May 23, 2013 - link
Why does the review author continue to be evasive regarding identification of units shipping with the tested firmware revision? Just review a damned retail unit and restore the reputation of AnandTech as a legitimate reviewer. Otherwise this whole review is just a joke. Chris has basically reviewed a mythical, maybe never to be released, one-off that may or may not bear any resemblance to a display of the same name which is available for sale. If I reviewed a Chevrolet stock car as representative of a showroom model you'd laugh me off the web. Joke.retlaps - Monday, June 3, 2013 - link

Any idea if the LG 29EB93-P has these updates as well? I'm trying to decide between the LG 29EA93 and the 29EB93-P I would much prefer the nice stand and more professional look of the 29EB93-P but not at the loss of these nessesary updates.
