Am I Crazy for thinking G-sync isnt worth it? - Page 11

ULMB doesn't really affect the perception once you get going with it. Colours aren't something that are all too missed when focusing on the scenery in a high action, high framerate situation. To that end, ULMB still looks better than most modern TN panels, just needs a bit of extra calibration.

That's fine enough to want it, but are you willing to accept the change in average luminance that frame-by-frame strobe interval adjustment will cause?

VRR OLED monitors should satisfy him, if OLED ever improves to the point where VRR OLED computer monitors become a thing.

Which doesn't solve the average luminance problem. Whether it's a pulsed backlight or a pulsed emitter, maintaining constant average luminance is not a trivial problem.

I think it's many times over better than standard Vsync or Vsync off ... with a qualification ...

If I can keep my framerates around the 120fps mark, or better, then I'll take G sync on or off and notice little difference ... though if the game is fluctuating wildly between say, 120fps and 45fps, and hitting all points in between ... then G sync *absolutely* is a game changer for me. My modded Skyrim install does this sort of extreme fluctuating *constantly* and without G sync, it's painfully obvious/noticeable ... but with G sync enabled, it's something I notice far less. That said, even at a solid 120fps, I find G sync a more fluid and enjoyable experience over V sync (others are not so sensitive to it but I notice the lag associated with V sync, quite acutely).

Otherwise, I would also have to say that playing at lower framerates (40 to 50fps) is much more enjoyable with G sync.

I'll personally never buy another non G sync monitor.

But as mentioned ... we are all more or less sensitive to these sorts of things and so I don't think your personally wrong in your preference at all ...

Benq blur reduction and Lightboost were not affected by this.
Benq blur reduction I think actually used some of the logic from the internal lightboost hardware and modified it so you could adjust the phase. Found out since the older non blur reduction T/TE series monitors would accept a Vertical Total VT 1502, which we used on the later blur reduction monitors to lower the amount of strobe crosstalk. And VT 1502 was the highest vertical total the monitors would recognize (VT 1503 was black screen out of range), and you could even create higher custom resolutions (higher than the native 1920x1080) IF those custom resolutions would accept a vertical total between 1497-1502. 2560x1440 would accept such a VT, but only refresh rates from 61-100hz would work for it (60hz would black screen, because VT 1502 won't even work on the Z series blur reduction monitors at 60hz (The max was 1350 or 1260, I forgot) but would at 61 hz. But anyway it seemed like Lightboost mode was sending the VT 1502 signal to the monitor scaler to give it the lowest amount of crosstalk possible. But I'm getting off topic...

Lightboost mode and benq blur reduction mode both *increased* the current to the backlight LEDs from the default current, to compensate for the decrease in luminance from strobing. So you could use benq blur reduction and still have a nice bright screen, if you raised the strobe duty up to lower the amount of blur reduction.

ULMB mode does NOT increase the current to the backlight at all, so the screen is noticeably dimmer with it on. This was one of the first complaints about ULMB that people noticed on the Asus VG248QE Gsync modules. ULMB also has more strobe crosstalk than Lightboost or benq blur reduction (with VT 1500 tweak).

*Edit* Just found some old posts complaining about ULMB on the swift looking worse than lightboost or benq blur reduction looked (except the colors being better in ULMB vs Lightboost). Wow I see now why you guys don't like ULMB.

I didn't realize ULMB was a step back quality wise (from lightboost).

*Edit* found some more pics. Definitely NOT getting a ULMB monitor now. I'm sticking with benq blur reduction.

Lightboost bottom of screen



ULMB bottom. MUCH WORSE!!!!!

ULMB shouldn't be as bad as that appearance. Correct me if I'm mistaken, but can't (pixel) Overdrive and ULMB be run at the same time? Where Overdrive helps in preventing those corona style effects? It looks like way too much overdrive has been applied there in that situation.

They can indeed run together at the same time. That monitor must not be very good or they just aren't using a good OD setting. No overshoot issues here with the XB270HU and ULMB.

That's not the entire screen.
That's the bottom, where the crosstalk is the worst.
Benq blur reduction looks just like this if you don't use a vertical total tweak!
Remember monitors refresh top to bottom, so the crosstalk will always be worst at the bottom. For the same reason the input lag /response time is fastest at the top (least crosstalk) and highest at the bottom.

Here is the ULMB at the middle of the screen. Looks about the same as lightboost.

Clear G-sync is an improvement over the world of vsync on/off. How much of an improvement depends on your sensitivity to tearing, lag, and vsync stutter. I'm sensitive to all three so I find it a vast improvement.

I was very excited to try ULMB as well, but in practice I've found I prefer G-sync in most of my games. ULMB looks amazing with smoothly scrolling images (like the blurbusters demos). In games I find that I tend to move the mouse in a more "bursty" fashion: I'm looking forward, then I whip the mouse 45 degrees to the right, pause for 50 milliseconds to see what's there, then whip again to a new viewpoint. Rarely do I sit there steadily sliding my view at a constant speed. So I find that I don't really get any benefit from ULMB whereas I do get the negatives (tearing or stutter due to lack of Gsync). I also can perceive the strobing sensation even at 120 Hz. I can't actually consciously see flickering, but I can tell as soon as the backlight starts strobing.
