I'm saying that with 1x Asus VG278HE 27" 144hz 1080p, 3x Asus PG278Q 27" 144Hz 1440p, 1x HP 23xi 23.0", 1x Asus PB278Q 27" 60Hz 1440p, and 2xAOC e2228swdn 1080p 60Hz monitors the difference is pretty much indistinguishable in terms of smoothness for 60-144 FPS. For my monitors with ULMB I don't even bother since the difference is also zero in terms of gameplay smoothness for me regardless of how many FPS I'm pulling. To me it's more of a canned data thing; having the ability to compare the monitors myself I put little faith in that sort of thing.
I understood what you said, what I didn't understand is why you didn't take 20 seconds to run the linked test. When I've done this before with folks, it goes sorta like like those "find the mistake in this picture" puzzles, where once pointed out, the error is quite obvious. I find that once folks run the test, seeing what to look for caries over to everyday usage.
So that's the basic jist of it. You don't compare video cards buy placing the 2 cards you are comparing in different builds, you test them under conditions in which "all other things are equal". I am talking about a "valid test" where all 4 conditions (30, 60, 90, 120) are presented on the same screen, on the same hardware, in the same room and under identical lighting conditions and, preferably at the same time. This test allows you to do that.
But of course, as always, the visual impact will depend on the weakest leak in a chain. I once had a user post a youtube video telling us that he used **this video** from a 144 Hz screen to decide he didn't need 144 Hz monitor ... ignoring the fact that youtube could neither play at the resolution of the subject screen nor the frame rate, and of course, you won't see 144Hz advantages viewing video recording that wasn't recorded at 144 fps nor on a screen capable of displaying only 60 fps.
As I said before, another link in the chain is one's visual acuity. Some people get headaches from ghosting, others don't ... it's all a measure of each person's visual acuity.
There's also the issue of response time and lag ... which differ widely from advertised numbers. Tested Response Time as per ISO testing . Lag Times 60 Hz (144 hz)
VG278HE = 7.6 Response time / 17.10 @ 60 Hz (10.4 @ 144 Hz)
Note how lag times jump from 10,4 to 17.1 moving from 144 down to 60 Hz
PG278Q = 5.5 Response time / (4.0 @ 144 Hz)
The 17.1 ms to 4.0 ms response time alone should be vieweable to most moving between the two Asus screens
I'm not going to bother with the HP / AoC as they aren't in the same category. TFTcentral writes with respect to the PG278Q:
We suspect a setting of 100 will probably be adequate for most normal users anyway, as the ULMB mode certainly brings about positive improvements to the perceived motion blur ... We were very pleased with the results though here with a marked improvement in perceived motion blur experienced. Tracking of moving objects became much easier and the image looked sharper and clearer. We used the BlurBusters full-screen TestUFO online motion test (all ULMB supported refresh rates) as well to put the feature through its paces and were pleased with the results.....The clarity of the moving image is improved significantly and tracking across the screen with your eye is much easier and clearer.
The support for refresh rates up to 144Hz is obviously a huge benefit as well, providing smooth, fast and fluid movement and the ability to produce high frame rates for competitive gaming. Response times were very impressive and fast, and while there was a little overshoot introduced it shouldn't present any major problems. The response times of the TN Film panel are fast enough to keep up with the demand of a higher refresh rate and provide smooth, ghost-free movement. The increased 144Hz refresh rate helps reduce the perceived presence of overshoot as well since more frames are refreshing the image on the screen, meaning any overshoot doesn't linger as long as it would on a lower refresh rate display..
The ULMB backlight worked very well also, offering noticeable and marked improvements in image quality and reduced motion blur when tracking movement across the screen. It was well implemented and even offered a useful control over the strobe length for those who like to tweak things a bit. It has minimal impact on the colour and appearance of the screen, although you do of course lose some brightness range. The lag of the display was also pretty much non-existent which was excellent news, and all in all this stacked up to what we consider to be the ultimate gaming screen currently.
So yes there are differences and they can be seen ... how well they are seen will depend on the contributing factors involved as described. When my middle son moved out, the youngest moved in and when he switched, He somehow mixed up the monitor cables and the one he use was not dual link DVI-D. He said it didn't look right to which I asked the usual "did you use the right cable ?", he assured me he did ... but after a frustrating 2 days, he checked and he had mixed up the cables. After the switch and return to 144 Hz, all was right with the world again.
So yes by all means, if **you** can't see any difference at 144 Hz, then you shouldn't invest in the technology. But because **you** don't see any difference, doesn't mean it doesn't exist. Most people can't tell the difference between an excellent wine vintage and the latest heavily advertised $7 bottle of Pinot Grigio; it would therefore be wasteful to invest in it.
When playing a game or watching video, the eye tends to focus on the story, the action and identifying what is in the scene. It sometimes take a much "cleaner" screen where the eye can focus on just one thing moving to see the effect. Most folks notice it is shooter games because they focus there eye on the target reticule and are able to see it more clearly because their eye is focused on just a small part of the screen.
If you ever invest the 20 seconds of your time to run the linked comparison on the Asus Swift, I'd be very interested in hearing your impressions of what you see.
