Input lag wars!, post your input lag results of your LCD display here for reference - Page 128

If anyone has any data on the input lag of this tv i'd die to know it. I'm really thinking on buying this one, or the LM670T, not yet sure which one. Do you guys have recommendations for either of these or some other model? The input lag is really important for me because the tv is going to be used almost only for gaming.

Thank you so much!

It says that lag is over 67 ms which is way too much for me, almost 4 frames.

Now I'm thinking Philips 5507, but i've read some reviews which say that the 3D is far for good with this tv. What do you guys think of this one?

EDIT: GeForceFX5200 pointed out wrong make, fixed!

You mean philips. The 40" seems to have insane clouding issues. 46" and up don't seem to be the bets thing out there, but when your weapon of choice is gaming - there's not much to choose from.
Unless someone has a better one to suggest, or CES13 turns out to have some gaming TVs - I'll probably be getting 46" ver. on my next salary.

lg-47lm4600

Does anyone have input lag information on that model LG TV? It's on sale right now at a price I can afford but I play a lot of fighters.
If you know anything or can point me to a review including input lag tests ,please help me out.
Google searching yielded me nothing so far.

Alright lets see what CES has to give for us. The sad truth seems to be that there is absolutely no competition with the 5507. Has anyone looked into tv's with no 3D support for example? I'm not that sure if i require it especially if it's not good quality, which seems to be the case with the 5507.

Found this one http://www.digitalversus.com/tv-television/panasonic-viera-tx-p50vt50-p13511/test.html with nearly just 30 ms input lag. I think it's not too much, as it's just around 2 frames. If CES won't bring new tv's for gaming i'm gonna choose between this one and 5507.

Don't be fooled by the reviewer's interpretation of what constitutes low lag. The reviewer said the following about the TX-P50VT50.....

"............and the low input lag of 33 ms makes it one of the best TVs out there for gaming."

What a joke. Ether this guy has never had the pleasure of growing up with a NES or SNES on a glorious CRT TV, or he has seriously forgotten what its like to play without lag. Saying that 33ms is "low" and that its "one of the best" is greatly out of touch with reality. He needs to try playing Mega Man or Contra or Mike Tyson's Punch-Out!! on CRT TV from the 90's, and then re-play those same games on the plasma he reviewed, and I guarantee you he will recant or rephrase his statement as he will see that he is grossly wrong, and probably say something like "I can't believe how much of a difference I can feel. How did I ever think that playing with lag was ok?"

Really... isn't the GT lower and the ST even lower again? But still around 15ms

Doesn't matter. Plasma. lol. But yeh, UT and ST I'm sure can do 1frame. Didn't look for higher models, but I wouldnt be surprised if they had around 1 or 1,5 frame delay.

Are there any 37" panels out there that will work as Computer Monitors, at least as well as my 37" Westy has behaved for so many years? I'd like thin to save on desk space (Edge lit LED is fine), I'd love the passive 3D that comes on LG sets...but LG doesn't make a 37".

I can't go bigger than 37"....I've tried 42, too big to live with.....40 might be an option but really, 37 is ideal.

Can anyone recommend something out there today....I don't expect much from 2013CES..it'll take half a year for reviews and tests and, indeed, product to ship. If I can get a deal on something out there now, it would be best. Suggestions anyone?
This will be 100% for PC gaming and PC usage...been using a Westy 37" via DVI-D for 6, 7 years now. Its ugly, its old, it gets image retention in the greys at the drop of a hat that can't be cleared except by unplugging the set.

To its credit, this set has been used nearly every single day for 8+ hours each day for the past 7 years. Freakin thing is a tank.

Actually, 37" is probably pretty easy to get. Anything above that seems to be insanely laggy (other than 1 or two exceptions who usually tend to screw up something else).

Thank you so much for the links.... appreciated!

Just got back from Frys. I took my new Leo Bodnar input lag tester (1080p version)

Here are some results I found:

LG65LM6200:
127.8 ms standard mode
31.2 game mode

LG55LM8600
Signal not detected from tester

Mits WD-73740 (DLP)
42.1 ms (there is no game mode)

Samsung UN55ES7500
Signal not detected

Samsung UN55ES8000
115.8 ms standard mode
49.4 game mode

Sony KDL60EX720
Signal not detected

Panny U50
27.1 ms standard mode
(I had to go, didn't test game mode if there was one)

I also tried to test my lagless Hitachi 51SWX20B (CRT RPTV) by plugging the tester in the aux in of my receiver hoping it would downconvert the signal from 1080p to 1080i but I just got static so I wasn't able to test that.

I'm going to e-mail Leo or John to find out what would cause certain TVs not to detect the signal from the tester...

The U50 does indeed have a Game Mode, hope you can double check it one day soon.

Psshhh all these dumbasses getting 40+, iv now seen 2 actually measurements for under 30ms.

If you happen to be back at Fry's, can you test the 47LM4600? I ordered it already and just took the risk because I figured it wouldn't be any worse than the TC-L47E50 I just sold. I've heard that is performs on par with the LM6200, but I haven't seen hard evidence.
The reason I ask is because this is a very large TV at consistently good price. For most of us gamers, we don't need smart features either.

Wow that's kinda harsh. I myself prefer a 32". I'm only trying to help out others who prefer 37" and above, just like when I got helped.

If anyone could help,I've brought the 47lm640t from currys this set is amazing 3d is amazing and sd is good,hd(sky) is perfect!! I play Xbox and I feel lag on all modes but game mode by far is the best,would like someone who as a lag tester to test the 47lm640 for lag if they can thanks

Huh? I didn't mean anything negative to you I just keep reading all of these posts about the Panny 50's being so much laggier than the 30's and now I have seen 2 actually posts from first hand poster both with the lag tester and picture method pegging them below 30ms now all I want to see is the lag tester in gaming mode, and on a ST and GT.

Lol, those words are not for you man. Your doing a great job testing the lag with that device. keep up the great work and helping others.

I think there has been a small misunderstanding. I'm not an owner of a lag testing device. I'm just trying to help in via giving the best advice I can at the moment. That said, I might purchase one of those devices. However, as you can see at SRK testing is being done by others, as well as people on this forum. Apparently many have purchased the tester and it wont be long hopefully until a huge database of results are quickly available. Things are looking up for the dark age of lag!

To anyone who has purchased the input lag tester from Leo Bodnar, please let me know approximately how many business days it took for you to receive it after you placed an order for it. I still haven't received mine yet and I'm getting worried that maybe it got lost during shipping. Apparently I have to wait 25 days before Leo Bodnar can start a loss claim on it with Royal Air Mail. I really wish I had paid extra for tracking now! :-(

Mine was shipped on December 20th and I received it on January 2nd. Two of those days the post office was closed and the other days I'm sure the post office employees were hating life. I paid extra for the tracking option which proved to be useless (the tracking does not actually update itself until after the package is delivered). They shipped from the UK and I'm in socal

Of course the day after I say I haven't gotten the input lag tester I find it in my mailbox! LOL. It took approximately 16 business days to get from the UK to my home state of Nevada in the US using the cheapest Royal Airmail shipping service in case anyone was wondering.I placed my order on the 17th of December so it was being shipped during the Christmas holiday.

Anyway, the first thing I did was test the device on my 32 inch LG 32LE5300 HDTV and my 24 inch LG W2486L monitor. I had previously tested the 32 inch HDTV against an old CRT monitor I had lying around. I couldn't test it at it's native resolution of 1080p with the CRT however because the CRT could only go up to 1024 x 768 but I generally got a 50 ms delay reading from the LG 32LE5300 against the CRT at 1024x768 in both Game Mode and Expert1 mode with all post-picture processing turned off in the advanced picture settings and using the executable program version timer from http://tft.vanity.dk/.

Here's an example picture from those tests:



I never actually tested the LG W2486L monitor directly against the CRT because of certain inconveniences of doing so but I did test it against the LG 32LE5300 and it appeared that the 32 inch TV lagged behind the 24 inch monitor by 50 ms according to numerous comparisons I made between the two displays with the aforementioned free software input lag timer from the http://tft.vanity.dk/ website.The 24 inch monitor certainly felt much less "laggy" during FPS shooter games than my 32 inch HDTV and I've noticed a definite improvement in my performance in fast twitch games when playing on the smaller monitor.

After receiving the input lag tester and trying it out today on both the 24 inch monitor and the 32 inch HDTV I have come to the conclusion that it works as advertised and appears to be much more accurate than the older method I used with the software timer and a digital camera with fast shutter speed provided it is used properly which I will explain further in the post.Here are the pictures of the results of the tests I made with the Leo Bodnar input lag tester (1080p resolution output version) on both displays.

Please note I have the VA panel version of the LG 32LE5300. It is a "panel lottery" HDTV.Sadly I was not lucky enough to get the IPS panel version.

LG 32LE5300 tested at 1080p resolution in Expert1 mode with all post-processing turned off in advanced picture settings:


LG 32LE5300 tested at 1080p resolution in Game Mode with all post-processing turned off in advanced picture settings:


In short, no real difference between the two modes with advanced post processing settings (Dynamic Contrast, Dynamic Color, Clear White, Skin Color, Noise Reduction, Digital Noise Reduction, Eye Care, Real Cinema, xvYCC) turned off. The input lag tester seems to coincide with my previous findings of 50 ms delay on average with the older testing method but with a little more accuracy by a few milliseconds. As you can see, this TV is pretty bad for gaming.

LG W2486L monitor tested at 1080p resolution. No settings that would appear to affect input lag to turn off.


9.7 ms! A very good monitor for gaming! I'm glad I had it lying around after finding out about input lag! I just wish it were bigger.

The Leo Bodnar device is fairly easy to use with a few minor annoyances.
You have to hold the button down while you are positioning the sensor on the side of the device facing the display over one of the blinking white rectangles that appear on the screen while you hold the button down. I noticed that when I placed the device over the blinking rectangle in the middle of the screen it gave different results than the one on the bottom edge of the display.My theory is that if the input lag testing device is not completely flush with the screen it can negatively affect the test results.I will be using only the middle rectangle for all my future tests and will be very careful to make sure the device is flat against the display while testing.
It is also very important to line up the sensor with the rectangle properly.It is not that easy to do because there are no indications on the side of the device that you see while testing to show you exactly where the sensor is on the other side.I will have to make some markings on the device to make it easier to line up the sensor with the testing rectangle that appears on the screen.
Someone mentioned in a prior post that a few TV's they tried to test with the device failed to recognize the display output of the device.I was having the same problem with my 24 inch monitor but was able to get the monitor to recognize the output by selecting the source input at the same time that I pressed the button on the device to start the display output from it.My monitor goes into a power saving mode if it does not detect a video signal at the HDMI input immediately and I believe that this power saving mode must not be de-activated by the Leo Bodnar device's output signal for some reason.I also got an occasional message on my 32 inch HDTV stating that the output signal from the Leo Bodnar device was "invalid" for some reason as well.Once again, I attempted to manually switch input sources to the one that the device was hooked up to while simultaneously activating the device and it seemed to fix this occasional problem.I will be contacting Leo Bodnar to ask them why this might be happening and if there could be a hardware fix in the future for this problem.I will also be making some recommendations on ways to make the device more user friendly for possible future revisions.I won't regret purchasing the device even with it's problems as long as it continues to work like it has.

I'll try and get to Target and Best Buy over the next few weeks if my schedule allows to test some TV's. No promises however as I'm pretty busy this month. I'll post some test results eventually. I just can't say when.

Thank you for your reply!

I had originally included thumbnail size pictures of my tests in my last post about the input lag tester because they were supposed to link to the original large versions. I didn't realize when you select "Import Images" at the bottom of a thread post reply it would only import the thumbnails and not allow the link to the original large pictures hosted at another site. So here are the original thumbnails with working links intact. Just click on the pictures to enlarge:

Edit 3/2/2013: I just learned today why there are 3 testing areas displayed by the Leo Bodnar Lag Tester and realize that I have been testing TV's using the wrong testing area. All the numbers I've posted up to now have been results from the middle testing area. I will have to retest using the bottom testing area of the device since that is the testing area that will indicate the highest possible lag of the tested display. I will edit this and my past posts to correct the mistake.

That's a flash based stopwatch. Maybe one of the worst possible ways to implement a stopwatch that should be able to resolve milliseconds as flash is unable to calculate 1000 frames per second. With flash calculations are only done when a new frame is rendered. That's not the real problem but depending on the renderer flash renders new frames 12 to 120 times per second. That results in a precision somewhere between 0,1s to 0,01s. You can also add up to 16ms additional lag (of the stopwatch! Not the monitor!) because this rendering is not synchronized with the v-synced 2D desktop output but will only be displayed when the desktop updates....

If there's a sponsor I'd develop a FPGA based device with DisplayPort output and selectable resolutions... Problem: The FPGA board would cost about 3000 USD...

That's too bad. I don't think I'd want to spend much more than $100 on a portable input lag testing device. Is there no other cheaper alternative that you could use in a device of your own? I'd certainly be interested in buying something you developed in the future. It probably won't be too long before 1080p is as obsolete as 480p is now with all these 4K resolution supporting TV's coming out.

I'd wager it is going to take a long while before 1080p is phased out simply because the improvement in PQ isn't as noticable unless you've got a really large screen. Not to mention the amount of bandwidth needed to send 4K over the airwaves is quite a bit more than 1080p and they're not even sending 1080p yet, only 1080i.

1080p will be here for a long time, my friend.

I mean, it wasn't that long ago that BluRays became popular. The current format can't handle a full length 4K movie, so they're going to need to come up with some sort of medium to put true 4K movies on for sale as well... (That is... IF 4K becomes popular...) We're several years out from that!

I hate the idea of 4k. Heck, most people don't even have 1080p HDTV's, as most people currently own 720p HDTV's. TV stations don't even broadcast in 1080p, and most people are happy with DVD's upscaled. Heck, even I myself would be perfectly content with a 480i CRT Trinitron or something similar if HD had not ever come out, mainly because I watch my content for the ACTUAL CONTENT and NOT the visuals (although they are nice for sure). I hope and pray that 4k takes 20 years to take off or longer. I don't want to upgrade again and again and again (stupid 8k, 16k, 32k, 64k, STOP THE MADNESS ALREADY, 1080P IS MORE THAN ENOUGH).
