Sears has the 42" LG 42LH30 1080p LCD HDTV for $665. A review on AVSForum says it’s 0 lag.
Thought you guys might be interested in the deal.
Definately. I’ve always heard it adds lag so I left it off, but it would be nice to know exactly how much.
The only thing is that they used an LCD monitor (which has it’s own lag) to test the lag of the TV. I would think that the same series/different size should have very similar lag. That should put the 42LH30 about 31ms, which is still really good for a TV. When I get back to testing, I will see if this is true or not. Nice deal spotting… don’t forget BBY has a price match policy 
You can’t really turn off 120Hz. You either have 120Hz or 60Hz (or 240Hz), but you can’t turn it on or off. What (might) add latency though is the interpolation that the LCD’s do such as Sony’s MotionFlow, Samsung’s AMP, etc. This reduces the judder on the screen so that sports, movies, and tickers look smoother. Personally, I don’t notice a difference with interpolation on or off on my LCD, but then again it’s not my gaming HDTV.
If you read the post he states that the second LCD monitor was tested at 0ms min, 16ms peak, 6ms average against a CRT.
Sorry, didn’t read that far… I’ll test it later for personal curiosity.
If you don’t mind, what console are you testing this on, and are you using a VGA? I recently bought a VGA for my Xbox 360, because it was lagging before, and the performance is much better, now, but I want to know for sure if there is any lag.
I own a Samsung 40 inch 1080p series 530 60Hz with HDMI. The model code is LN40A530P1FXZA.
What I mean by off is that in the menu it has different levels of “120Hz” with one being off. I assumed this has to do with the conversion of the 60hz signal to 120Hz. No TV that I know actually accepts a 120Hz signal from a device. I’ve tried on a couple TVs before and all home devices (i.e. DVD players, cable boxes, Bluray players) are designed to run at 60Hz. If I am wrong in my thinking, I apologize, most of my learning on this topic has come from internet forums & personal assumptions.
Both ts279 and onimusha10154 tested the 32" version and they both stated that there’s 31ms lag. Most likely the 42" version will have the same.
If you read deeper along the tread on asvforum people were also having issues with lag.
I was using a PC with dual DVI outs… from there I am able to go from DVI to HDMI or VGA. My final tests in a coulple weeks will have results posted from both inputs & multiple resolutions.
We don’t carry the “A” series anymore, but I will try & test the “B” series then… One would think the results might be similar.
Ummm what? Generally when someone says “turn 120 Hz off” it’s presumed that they mean put it in 60 Hz mode. Not sure what you’re trying to say here beyond this.
The OP states that commercial grade displays are the way to go. I stumbled onto a 47" commercial grade 1080p LCD by LG. It’s available from a 3rd party seller on Amazon for about $900, shipping should add $79. Couldn’t find any info on its lag. How safe is it to assume on the lag of a random commercial grade display? Anyone have any experience with such TVs?

It’s true that this tv has a constant lag of 31ms on all resolutions and all inputs regardless of what picture mode you use. ZeroSum, if you read further into the avsforum post, you’ll find that KVW has stated that the lg has the same exact input latencey as a certain panasonic panel that was compared to a crt and said it was about 2 frames of lag, which pretty much tells us that the lg also has 2 frames of lag.
The only info the sheet had is that it’s 6ms response time. That doesn’t mean anything though.
The problem here is that the OP has assumed that commercial grade screens are typically for arcades and things like hospitals and stuff. This sort of display looks like it’s aimed at hospitality, events and public displays. One of it’s specs is ‘LGs XD Engine’ which doesn’t sound great to me.
There is very little information on testing done for commercial displays, so I don’t know for sure either way.
I have a Sony Bravia KDL40W2000 (PS3 connected via HDMI) and the GH 3 and GH: World tour calibration test gave me 0 ms delay.
This seems impossible to me, but I did it 10 times and it was 0ms 9 of those times.
Anyone got some insight?
The sound is a little off and the visuals on the bottom of the chart seems pretty off during fills. I do play expert drums on rb2, so I’m pretty confident in my timing sense. Also, I don’t do links in SF4 through muscle memory. At least not in training mode. I always look for a visual cue before pressing the link for Abel’s 1 frame link.
Unfortunately, I only have the RB1 equipment so I don’t think I’m able to do any sort of automatic test in RB2. Are there any other automatic tests out there? It’s not really a big deal to me tho, as the tv feels like it has no noticeable lag when it really counts. It only has a little in the strangeness that is RB2 fills.
The GH3 tests merely calibrate the system to your personal response time. The VGA splitter + CRT + camera test is the only reasonable way to measure input latency.
Ah, okay. I thought I had read that the Flatron (which he was actually testing against) was 0 lag, but it might’ve been marketspeak. Thanks for the clearup on the LZ800.
Has anybody tested the Samsung LED tvs? I’m due one in seven days. Will test it if it hasn’t already been tested.
Yeah, you’re right. The HDTV will only accept 60Hz (and 24), but if the HDTV is 120Hz, then the signal will always be displayed at a 120hz refresh rate no matter what even though the source is 60Hz. The settings in the menu such as Normal, High, Off (depending on your model) is for the interpolation, which is what gives the “Soap Opera” look. But even when it’s set to off, the HDTV will still be displaying at a 120Hz refresh rate. What I meant in my previous post is that you cannot turn off the 120Hz and have the HDTV display at 60Hz.
And yes, most home devices run at 60Hz, with most Blu-Ray players being able to run at 24Hz.
You can’t put it in “60Hz Mode”. If your HDTV is 120Hz, it will always be displaying its source at 120Hz. When it receives a source of 60Hz, it will duplicate its refresh rate to display at 120Hz. Those settings you see in the menu for Samsung’s AMP, Sony’s MotionFlow, Mitsubishi’s Smooth Motion, etc. are for interpolation, which is what gives the “Soap Opera” effect. But regardless of those settings being Off, Normal, High, etc. the HDTV will always be displaying it’s source at 120Hz.
