Is that really noticeable vs. a CRT ? I doubt many people could actually tell.

Also the XBR 960 is famous for being among the few CRTs to do interlacing+deinterlacing and image processing for aspect correction, on practically everything you feed it and generating input lag, which is likely to be over 1 frame.

Maybe it's a case similar to the plasma motion placebo effect, that for years made people claim plasmas had less lag than LCDs by default, but this isn't true, rather the better motion made users 'just feel' it more responsive.
It's possible that you enjoy more playing on the XBR960 because of its CRT properties, but in reality it is very likely that it is your LG can produce the least lag and the purest picture.
I agree with all of that. good post

I have not found that be the case with my sets. Even at 720p is at 21ms in both hdmi and component. 480p(regardless of screen mode) is 21ms in HDmi, yet 38ms over component. Perhaps I'm misunderstanding your statement but I find the 34xbr960 pretty excellent, especially if you can send it 1080i as I've posted above measured equal to the SD crts and my apple studio monitor.

The ps4 pro comes with a handy overscan option which makes 1080i shine on the 960.

Yep, those Hi-Scan and Super Fine Pitch FD Trinitrons like the KD-34XBR960 were a good ~2 frames behind on lag vs an analog CRT TV. Lots of TVs are faster than that these days.

Here's a Hi-Scan Sony KV-27HS420 doing it's laggy thing:

Don't forget that Youtube lets you step a video frame by frame with the comma and period keys when paused the video is paused.

I see your video and raise you one of my own! Actually I believe sending 240p over component(hdmi won't sync) gets treated as 480i in all drc modes and has a whopping 54ms!

Using the OSSC line double worked and the time sleuth does 21ms over HDMI. Unfortunately I couldn't get like triple going. If only the OSSC could do 1080i...

Are you still quoting lag at the middle of the screen ? or top ? or bottom ? specify all measurements otherwise it's worthless.

You - everyone - has to understand once and for all that top is the input lag, middle is it + 1/2 a frame, bottom is input lag + 1 frame (except in specific cases but that's not the issue, what's more important is to call a cat a cat, you have a lag tester: use it properly and give us all the measurements figures)

HDMI. Top. Middle. Bottom
1080i. 00.83ms. 7.44ms. 14.81ms
720p. 14.88ms. 21.58ms. 28.74ms
480p. 14.98ms. 21.24ms. 28.39ms

I tried using screen sizes(Full, Zoom, Normal) for 480p and it made no difference despite seeing many posts saying they do. I hope everyone is happy with these measurements and I tested this on two seperate 34XBR960s that are right next to each other.

Lol there is a little miscommunication sorry, I was talking about/expected measurements from your OLED, but this is also quite useful, you're the first person to post full lag results for the XBR 960.
Its input lag in 480p and 720p is 15ms then, that's good really.
1080i is lagless apparently, which is good to know.

Can you try a 240p input too ? also using the resizing and aspect settings please (this is where it matters, ppl complain about the lag with it, which could be higher than with 480/720p...or not, you have to find out)

(and definitely test and post the LG as well)

I'll start up another thread since the lag has derailed this one.

Yes. Hdpt only effects 1080i. All the other settings like mide or yosw were irrelevant.
