I'm suprised this has not gotten any traction anywhere. Suspiciously anounced alongside the launch of 1440p 500hz qdoleds.
Only reason i am posting this here is because i hope someone with contacts at lg display can tell them a dual mode at 720p 720hz is not very usefull. For a bunch of various reasons but the important one that will be discussed. If a user wants interger scaled 720p for some odd reason. They can set it it manually.
Therefore it is in LGs interests to make the dual mode 1080p 720hz (10bit, 54gbps) and or with an "overclock" up to 900hz (10bit 78gbps).
1440p 540hz /720p 720hz woleds going into production this year.

Re: 1440p 540hz /720p 720hz woleds going into production this year.
720p 720Hz integer is more useful than 720p 540Hz integer scaling. Although all these LG's DFR dual modes seem to not scale perfectly integerly. It lands exactly between standard blurry bicubic and ideal integer scaling (viewtopic.php?p=112106#p112106).
What I'm wondering is how does DFR even work? Why is it limited to 720Hz (x1.33) instead of 1080Hz (x2) like on previous monitors? Bandwidth shouldn't be a problem, especially with DSC. Maybe scaler limitation or something else?

Re: 1440p 540hz /720p 720hz woleds going into production this year.
In the press release they talk about 540hz only being possible due to new algorithms. So maybe they just don't have the code to account for data correction at that 1ms level.
An advanced user elsewhere on a seperate topic was wondering if the reason 4k 360hz oled displays still don't exist yet is because they are worried about voltage control.
I have a 32 inch bgr 720p tv that i still use often. It is a horrible experience up close. 720p at 27 inches that isn't even likely true interger is going to be way worse than what people remember 720p as.
I wrote some stuff but maybe it's the real reason its 720p only. 1440p even if upscaled at 720hz is 123gbps. Cutting that data in half should still be doable though so ¯\_(ツ)_/¯
If it does end up that they truly cannot offer 1080p 720hz yet. It is why i mention an overclock. Set it officially to 1080p 600hz and allow overclock to whatever possible.

Apparently rather than having a whole second edid inside the monitor. This 720hz mode might be done through software. Something LG calls Dynamic Frequency & Resolution (DFR) technology. I wonder if this means they will open up overclocking abilities. Otherwise if tft is correct about the 720hz mode being hd /720p. Then it will really limit it to niche of niche
Basically multiplayer games from 2005-2010, 2d games like Osu! , boomer shooters and esports games will be the only ones you would play at 720p 720fps.
1440p 540hz is 82gbps of data. Meanwhile 720p 720hz is only 32gbps. So i have to wonder if they really wont allow for other resolutions (overclock or not) with that much leeway. 1080p 600hz 10bit is only 54gbps. Of course it won't be interger scaled but that's okay. It's still going to look better than outright clean 720p. Plus the 2k mode on the 4k oleds isn't interger scaled either so ( ͡° ͜ʖ ͡°). I have never heard of people preferring to watch 720p youtube or movies over 1080p ones just because they have a 1440p display.
1600×900p 720hz 10bit = 49gbps. 900p 900hz is only 70gbps. So if it's even possible. It might be better to just go above 720hz. Also going above 720hz would not have much meaning for 720p.
Basically... Just let us overclock oleds.
