any widescreen w ULMB?

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, Turbo240, ToastyX Strobelight, etc.

any widescreen w ULMB?

Post by bwana » 17 Dec 2020, 17:21

I cannot seem to find any wide screen monitors (3440x1440) w ulmb. I know there are a bunch of NVIDIA g-sync monitors which have adaptive overdrive to decrease smearing but there is no mention of ulmb. Is this feature being discontinued? Or is OLED soo good that for LED monitors, the writing is on the wall.

To the contrary.

It's because most ultrawides use VA panels. They're usually too slow for good strobe tuning. So instead of offering bad strobing, they are not included.

OLED still has motion blur, see OLED Motion Blur.

The future is strobeless blur reduction though, aka 1000fps 1000Hz -- low persistence sample-and-hold -- strobeless ULMB -- Blur Busters Law: The Amazing Journey To Future 1000Hz Displays. Basically brute-forcing the motion blur out with sheer frame rate and sheer refresh rate, using frame rate amplification tech.

Right now, if you're shopping for ultrawides, almost all of them have worse motion blur than the non-ultrawides, because of slow pixel response (VA) as well as lack of strobe backlights. And frame rates are often too low to easily be motion blur reduced, since you need high frame rates for successful strobe-based motion blur reduction (ULMB) and way even higher frame rates for strobeless motion blur reduction.

There are lots! But none is ideal:

These notes are based on various reviews, mostly from TFT Central (unfortunately I can't link them here).

Acer Nitro XV340CK - 3440x1440 IPS - 80, 100, or 120Hz - Unknown brightness and strobing has two settings, but it's a dim display to begin with (250 nits without strobing). It's also flat, which some prefer.
Acer Predator Z35 (2016 version, not the newer Z35P) - 2560x1080 VA - 85, 100, or 120Hz - 111 nits max (weakest blur-reduction setting) - also poor response times
AOC AGON AG493UCX - 5120x1440 VA - 120Hz - can't find evaluations of blur-reduction feature, but it has one!
AOC CU34G2X - 3440x1440 VA - 100, 120, 144Hz - 178 nits at level 1/20, 125 nits at 10/20, 65 nits at 20/20 (250 nits without strobing) - decent performance, pixel response times are middle-of-the-road for modern VA panels. Maybe the most promising though?
Asus ROG Strix XG35VQ - 3440x1440 VA - 100Hz - 164 nits - poor performance
Cooler Master GM34-CW - 3440x1440 VA - 100, 120, 144Hz - 313 nits at weakest blur-reduction setting - mediocre to poor performance
Gigabyte G34WQC - 3440x1440 VA - 144Hz - unknown brightness, but one review says it reduces brightness by 20% at its lowest setting. I couldn't find any UFO pursuit-camera tests. Promising at only $399 though.
LG 34GK950F (but not G) - 3440x1440 IPS - 144z - 235 nits - can activate at 120Hz, but actually strobes 144Hz anyway. Also looks to be a poor implementation.
LG 34UC79G - 2560x1080 IPS - 60 (double strobed) 100, 120, 144Hz - 141 nits - poor performance
LG 38CU99 - 3840x1600 IPS - 75Hz - 213 nits - mediocre performance and flicker city
LG 34UM69G - 2560x1080 IPS - 75Hz - can't find tests, but not really an option, is it?
MSI Optix MAG301CR - 2560x1080 VA - 200Hz - manual says blur reduction won't work in 75Hz - can't find other info - a promising option for low-res gamers?
Viewsonic XG350R-C - 3840x1440 VA - 100Hz - no brightness figures, but IGN review said display looked "dull."

There are also the Iiyama GB3461WQSU (3440x1440 144Hz flat IPS) and GB3466WQSU (3440x1440 144Hz curved VA). They're available in the UK, but I can't find any in-depth reviews that evaluate their blur-reduction features. The manual for the GB3461 says MBR is available "above 75Hz."

There's no mention of a minimum refresh rate for blur-reduction on the Iiyama GB3466. The GB3466 looks to be very similar to the Cooler Master CM34-CW (according to their manuals, they both have five blur-reduction levels), but the KitGuru review of the Iiyama GB3466 reported 91% DCI-P3 coverage vs. the Cooler Master's claimed 95%.

None of these monitors seem to use the new "Fast IPS" type panels or Samsung's new VA technology they used on their G7 and G9. The upcoming Samsung 34" G5 might have it, but the implementation on the G7 sucks, so I'm not getting my hopes up.

Chief Blur Buster. any more information/corrections about any of these?

thank you. I decided on an oled for now. But I cant figure out how to get 120 hz out of an LG cx 65 with a radeon 6800xt. I'll post another thread if I dont find that info.
