NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

[BLooDS_inc]

On the Msi monitor sleep bug going out, now pulsar working after sleeps well, but borderless bug in pubg stays here, when u get 2 monitors, and u set borderless mode ingame, pulsar stops working and monitor osd shows 144 fps(my 2nd monitor hz cap) instead of 342 that stays ingame(342 rtss cap), and gsync stops working too.

Trying the 60hz and 120hz modes, on 60hz in 10 width(the minimum u can set) flicker is very minor and u can use it, on 120 hz i don t see any flickering at all.
And now the GENERAL problem of this modes - if u use pulsar with 360hz ingame, and u wanna set 60 or 120hz modes, u cant do this fast, u need to change hz of monitor, turn off gsync, its so annoying idk, every time doing this, if u can get some BUTTON in nvidia APP that 1click turn on 60hz ulmb2 or 120hz ulmb2 and reverse 1click turn 360hz PULSAR it will be so good, but now, i dont wanna every time go in to the settings and set this changes over and over

its pretty good *i was a bit too harsh

holy moly 120 global strobe is CLEAR

Is it really global flash? I'm now a bit confused with the current situation. Is it:
- 240 and 360Hz rolling flash (method 1a),
- 120Hz global flash (method 2),
- 60Hz rolling flash (method 1b)?

I thought for 120Hz they'd go with the same method as 60Hz ULMB, which is a modified version of rolling scan. And we have footage confirming 60Hz is rolling. Global flash would mean they introduced additional method.

To confirm, can u record 120Hz ULMB PW 100 in slow-mo? And just in case check if 60Hz changed.

Also it would be nice to have some images of full screen crosstalk. Does crosstalk improve/worsen by lowering/incresing pulse width? Is the phase optimal when doing so? U can use testufo, or if u need sync track use this pattern image for Smooth Frog.

They called it "global flash" in the patchnotes so I just repeated it, but that mightve lead to confusion... sorry! It is the same behavior as the 60hz mode. I think they just call it global flash because at the lowest PW it basically is for both 60 and 120 (That was the whole rolling the backlight faster, but later into the actual panel's refresh behavior as PW lowers. Also caused the scanskew and top to bottom lag gradients to exist at PW100 but become less pronounced as PW goes down and effectively disappear at PW10)

I have trouble getting clean fullscreen pursuits by hand with my phone at the higher speeds needed to really pick apart these modes so I've been shooting them upclose (where I can slide my hand across the bezel of the screen as a stabilizing "rail" and shoot with my phone against my arm to photograph towards the center. It gets the job done... somewhat) In the meantime I can atleast describe to you what I see.

Using testufo crosstalk at 2560px/sec...
(Unsure if it's always the same so I'll just say there's 20 rows of UFOs for me, and I'm counting row 1 as the top and row 20 as the bottom)

• Row 1 has a faint image infront of the motion
• Rows 2-5 have a very faint image behind the motion that looks like the slightest bit of inverse ghosting. It gets less noticeable row by row as you progressively get closer to the sweetspot zone. Shows up as the background being a hair darker behind the UFO. You REALLY have to look for it to notice. I'm not even sure I would get it to show in a phone photo in rows 3-5 it's that subtle.
• The bottom six rows have a faint image behind the motion that gets more noticeable as you go down as you'd expect. Still, the bottommost row looks pretty good all things considered.
• Everything inbetween what I described above looks pretty much bang on perfect.
• PW does not appear to have any noticeable effect on the placement (phase?) of crosstalk/sweetspot areas or the size of these areas. Though the higher persistence settings start to hide the subtle artifacts with motion blur. If "optimal phase" is meaning that the top and bottom extremities are where the artifacts are and there's a big clear zone in the middle, then yes it is tuned that way and appears to stay that way throughout the PW options.

I'll stress again that I'm splitting hairs as much as I can. In actual games, only very high contrast + high speed motion touching the top bezel or in the bottom 1/4th of the screen really has any noticeable artifacts and they are still pretty subtle at that. The only thing that bests this 120hz motion that I've seen in person is a quest3 which looks perfect top to bottom as far as I can discern.

I'll take a stab at some slower pursuits to get cleaner fullscreen shots, but I'm not confident it will be able to show the tiniest of details I described. At the very least I should at least be able to show the mode is pretty darn good.

wouldnt it just be better, to have rolling scan, but reduce the duty cycle more?

As I understand that is essentially how the ULMB modes work. The lower PW is set, the faster it rolls the backlight top to bottom, shortening persistence, but does so closer to the next display refresh to still allow time for g2g to complete. As PW keeps going lower the backlight roll becomes so fast that it overcomes the backlight diffusion problem and gets closer and closer to a global strobe until it effectively is one at 10PW.

You think the reason they are hesitant to release standard 240hz and 360hz high quality ulmb2 because they need people to upgrade to there newer models down the line or because people with amd gpus who will just use this mode over pulsar that they can't

As you go up in hz you have less headroom to allow transitions to complete which causes even more crosstalk and shrinks the sweetspot. I still am hoping for a slight more crosstalk but lower persistence compromise for 240hz ulmb, but I'm not sure how much more can be squeezed out for 360hz improvements.

The 120hz mode has stunning clarity, very low to non existent crosstalk across the whole screen (let the monitor warm up fully). No perceivable flicker.

3840 Pixels Per Sec looks clear to me on the UFO Ghosting test but very hard to take a picture of at that speed.

A great mode for single player, controller games!

Brightness figures pretty much match up with the 60hz mode but the clarity is better at more pulse widths.

[MSIfanboy]

pulse width 60 is clearer than 360hz ulmb2, i think even higher is clearer, because ulmb2 mode/pulsar has strange hazey blurry look, despite white squares in the ufo

Nvidia already mentioned they are going to implement the idea of automatically changing ULMB 2 mode/refresh rate/pulsar using nvidia app in a future update so eventually you won't have to do anything except wait for a black screen as the monitor switches display modes.

holy moly 120 global strobe is CLEAR

This is the best picture I got freehanding my phone at 4920px/sec (1/30sec shutter used) It's so fast that it's hard to get a fully clear pursuit outside of just the center of the photo.

There is very slight crosstalk showing at the very top of the screen and the lower ~1/4 of the screen. It's shown in the photo trailing the lower white frog (moving right to left), it's not at all bothersome to me especially with such a massive clarity jump.

I'll see how well I can do getting an mprt photo

Great pursuit photograph, thank you!
That is definitely an absurd speed if true.
Definitely <5% PW in that mode, which makes it the first desirable ULMB2 experience on this display.
Could you do a TestUFO pursuit photograph at 1920px/s & 3840px/s on PW=20?

Thank you for providing the brightness value at each PW setting!
