Nope. More and more are popping up without it. The Z35P & AW3418 are the "newest" Gsync Ultrawides with one being VA and the other IPS, neither having ULMB.
It kind of makes sense NOT to have ULMB on those 2 monitors tho since they are natively only 100hz and neither of them does guarantee a stable Overclock to 120hz.
I've seen ULMB on 100hz monitor and it flickers like **** and makes everything very dark.
No ULMB on native 144hz panel with G-Sync that haven't happened before IIRC.
If it's a new panel and not a rehash of the Samsung VA, did they make a 27" version as well? And more importantly what are the transition speeds and quality, something that is abysmal on the Samsung panel. Pixel structure?
Asus using this panel or the Samsung in their upcoming monitor what ever it's names is and is confusingly listed by some sites as IPS some as VA and no one can decide what it will be?
There is no mention of ULMB in the manual (post #29). It has pictures of all the menus.
I think it is AUO panel most likely. Some custom flat design for LG. Their curved panel has the same bitdepth (8bit) and the datasheet explicitly states 165Hz as max timings.
The Panda panel has the wrong bitdepth and refresh rate. Samsung is also possible but more direct competitor to LG than AU. InnoLux sometimes supply LG but they don't have any 1440p panels at that size and they haven't made any gaming panels for some years.
I guess we have to wait for Newegg to ship it so somebody can look under the hood and check what panel it actually is.
My bad, that's a plus then. Or maybe I meant the ASUS one is curved. Anyway, no curve is a plus from my POV, both quality and usage wise.
ULMB is not on all Gsync monitors, the module has it, but that doesn't mean it's enabled for all panels. Usually slow panels don't have it enabled...
The pricing and 32" 1440p is a no go for me, but otherwise it may not be that gloomy if one is OK with the VA issues and at this size.
Either LG panel or AUO supplied. Who knows. At least some alternatives finally even if there is no competition really between the brands.
