[Redmi K20 Pro / Xiaomi Mi 9T Pro Themes, Apps, and] Espmic86:
you actually use my same config after many tries, i also arrived at the final, best, mixed solution this way:

xiaomi.eu 11.0.5.0

immensity kernel 8.2

dtbo 75 hz for evolution 3.5

no anti flickering / dc dimming

doesn't make any difference if i uncheck or check disable HW overlay (first install magisk module)

this way rocksolid stable fps 75 with no drop, 75hz, this is actually also THE ONLY way that guarantees on Q 75hz WITHOUT any DC dimming on, WITHOUT any green tint, and mostly important the onlly solution to pass testufo rocksolid 75 locked fps test on CHROME with no drops, which actually doesn't work with other solutions, other solutions work somehow maybe in stock browser, or in dolphin, but since this works in CHROME it's the proof that it's systemwise working, embedded, with no conflicts in revelation of refresh, hz, polling, device specs and files/kernels, so that's the same reason why, somehow, using those files, the developers created the best solution in the codes that probably mix some related stuff they don't even know, just as a result of casuality, reason why for example the same perfect solution doesn't work with 80hz or 69hz, upper or lower.... just the 75hz one works (Whatever rom, kernel, or dtbo you use, you won't reach this final result, reason why we should make a single new post with all final best customizations available for Mi 9T Pro grouping all solutions mixed in 300+ page for the ULTIMATE SETUP in a single new fresh post quoting original developers and also users which contributed at testing finding solutions, such as you for example).

Now, considering all the above, this should best work as well using the evolution x 3.5 rom, but now we have finally an ultimate solution for xiaomi.eu roms, also to consider that there is no difference in 69hz mod to 69hz, and that above 80 there is instability, green tint, need dc dimming and battery also flies (still, doesn't work 80hz mod with any solution, not even 90).

THE ONLY PROBLEM AND HERE I ASK YOU PLEASES TO HELP ME, NETFLIX DOESN'T WORK, DARK SCREEN OR ERROR CODES, even reinstaling, even unticking/disable the "disable HW overlays" option in developers option with magisk module installed.

NOW WAY to let netflix work, some how installing old apks, rebooting, sometime 1 on 10 it works, but it doesn't recognize the system as a full hd HDR L1 device, but only SD 540P no VP9 and no HDR. but online once on ten times, mostly, netflix doesn't work at all..

Could you please make tests yourself? maybe it will work on evolution 3.5 x rom, some says it works just unticking disable hw overlays, but no way here, the only way is to stream it over a chromecast and a TV.

Considering this mod, plus viper working with tube amplifier and some personal settings i woudl suggest, considering the final working dual speaker stereo mod, considering kernel improvenent and change, considering the i get 460.000 points in antutu which is abose k20 pro premium, WAY ABOVE note 10 plus, almost close to ROG 2 phone, i think we must make an ultimate, simple, single thread with all links, greetings and suggested settings for the MUST HAVE ULTIMATE SETUP rom, kernel, magisk, twrp, settings, dtbo, viper, dual speaker, cloudflare, VANCED youtube with background, both system and apk secondary, plus some privacy improvements fouad whatsapp with double or triple number, plus the perfect solution for adblock and popup blocks and inibition of determinate porn/walware viruses sites and web links... and we can give to the final user a one single thread solution for the PERFECT MUST HAVE ULTIMATE SETUP guide.

Cause seriously guys, 89% of people comes here from elsewere, they look for their needs, they find nothings, threads are mixed, confusionary, long, and solutions DON'T WORK at all, and no one can read 300 pages, you must consider basic user which doesn't even understands how to go for problem solving or making personal tries, he doesn't have the basic know how, and just fails wth installations or break the phone.. we should this way give to the final global user (90% of the world) a single mi 9t pro thread with MUST DO things list, very sinmple and short... i think it will just be the first and ultimate most read thread from outside for ALL USERS in the world... consider that to have a stable setting and solution we had to make months of tries, different threads, tons of pages... but who arrives here, to be honest, DOESN'T FIND anything he really needs... like lost in the ocean, you got the point... for example the perfect solution for dtbo for all xiaomi.eu users (90%) is in your thread, in almost after 90 pages, in the middle of almost 150 page thread, and no one highlighted it... that's not good at all. Must make some cleanings here... i'm new and would be stupid making a guide, i think the best king of the kings of mi 9t pro xda most active member should consider a cooperation for making the best setup and all in one guide for all above mentioned mods, otherwise we could find the time to make it, of course it's not our job, just a colection of the final results we reached thanking all original developers and users.

ANYWAY now i have in the final ultimate setup only this problem....... NETFLIX, black screen, no l1, error codes.... whatever kernerl, whatever dtbo, whatever tick yes or not on HW overlay option... whatever old APK... did you find a solution or could you try? i'll try setting up the above mentioned ultimate setup and secondary apk an magisk modules installations and settings using evolution x 3.5 rom but honestly we must find a solution also for xiaomi.eu roms which guys outside there mostly use, as i said, 90% of them.
