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.Edited by amisfit - 1/7/13 at 10:25pm
