Best ULMB monitor and 50Hz hack

Post by nuninho1980 » 14 Jun 2020, 13:10

Hello.

Is best ULMB 240Hz/144Hz TN/IPS monitor as less persistence time as BenQ XL2411P at same brightness?

Is newer ULMB monitor less crosstalk than BenQ Blur reduction?

What's best ULMB monitor with 1ms or shorter response time but maximum 27" and 50Hz is very well (no any issue (crosstalk...))?

Almost none of us have experience with 50 Hz strobing because we’re in NTSC region (60Hz+) and few tests for strobe rates that low at the moment.

Sites such as RTINGS.com that test for low-Hz strobe, only tests to 60Hz. You might want to suggest to RTINGS about getting a 50Hz strobe test done, as well.

However, as a general rule of thumb, monitors that support the ULMB “hack” at 60Hz, will also generally also do 50Hz with the same hack. Cannot guarantee if it will work, so make sure you are able to exchange the monitor it this is a primary goal of yours...

Thank you.

@moderator or @guys: What are brand+model's monitors with NVIDIA ULMB list for successfully 50Hz hack with minimum crosstalk?

I don't think anyone of us, nor any other forum members have done 50Hz strobe tests.

However, 50Hz successfully works on all ULMB-hackable monitors.

Thank you. :) I use CRT monitor 17" ;) but I wait to buy ULMB (probably)... OLED(?) monitor during next 1 or 2 year(s) because the best IPS panel with ULMB has only 4ms response time in current year.

PS: I tested BenQ XL2411P with high AMA (fast response time) and with Blur Reduction enabled and I got bit flicker when stone wall was horizontally scrolling on Crystal Caves game (MS-DOS) - see screenshot -> https://steamcdn-a.akamaihd.net/steam/a ... 1567627836 <- while I get no any flicker on any CRT monitor. :)

I also interested to have up to 50Hz single strobe available, for test and compare Vs non-strobed, and see if worth it trade motion blur with flicker. I'm from Spain, and here video streaming is 50p. But flicker is very hard on LCD at these low frequencies 50-60Hz, due to backlight on/off the whole screen at same time.

It would be much better if there was an OLED monitor with BFI, but at the moment i think that none exists. OLED panel BFI not strobe all screen at same time, do rolling scan, that help to smooth the flicker. Both CRT and OLED use this method.

New LG OLED TV CX 48" 4K 120Hz HDMI 2.1 can do 60Hz and 120Hz single strobe at several BFI lenghts, due that internaly the panel work at 240Hz. From what i see on Youtube test, have very good quality for 60p streams and games, and 120 for HFR video or modern games. But i not know if this BFI (Black Frame Insertion) can also be activated/hacked for UE people where TV streams is 50p and HFR (sport video) is 100p. If any test BFI in this TV, please try with more frequencies to see if work also, and share the result, thanks ;)

About "wall flicker" when panning in these old game, i suppose it will be "Pixel Inversion". LCD can't do perfectly focused panning when some pixel matrix are showed, you can see more info here. I think is related somehow with raw response time limits.

http://www.lagom.nl/lcd-test/inversion.php

I tested two monitors, LG 43UD79B 43" IPS 4K 60Hz and BenQ GW2270H 22" VA FHD 60Hz, and both show pixel inversion in all of these lagon PI test. With 21" CRT panning is perfectly sharp at all resolutions and frequencies.

Chief Viewsonic XG270 can show these matrix panning without issues in strobe mode ?

Can ASUS ROG SWIFT 360Hz PG259QN work 50Hz and 60Hz single strobe (but "hack" needed)?

Just tested to find out. The answer is yes.

ASUS PG259QN Supports Single Strobe ULMB 50 Hz and ULMB 60 Hz

I just tested now. PG259QN 360Hz still supports the Custom ULMB Hack.

50 Hz single strobe -- works, I tested these timings on my PG259QN via NVIDIA Control Panel:

The problem is it's extremely hard for newbies to calculate (multiple steps) and extremely hard to do in ToastyX (timings didn't save properly), but here are instructions.
1. I used the method found in the old FAQ ULMB 60 Hz Hack, then I screenshotted the ToastyX numbers.
2. Then I recreated it directly via NVIDIA Control Panel (Manual method)....and it worked!

You have to use the exact Pixel Clock of a working ULMB refresh rate and keep increasing Vertical Total (to increase the Pixel Clock and lower ULMB refresh rate) until you successfully get the low-Hz ULMB. Don't edit the refresh rate, you have to keep increasing Vertical Total until you reach your target refresh rate. You need to achieve as close as possible to exactly 346.4240 MHz pixel clock (via ULMB 144Hz timings) with any sub-144Hz ULMB refresh rates, and you need to achieve exactly 597.7800 MHz pixel clock (via ULMB 240Hz timings) with any sub-240Hz ULMB refresh rates.

60Hz Single Strobe Timings for ASUS PG259QN (derived from 144Hz ULMB)

I did not test the 50Hz & 60Hz single strobe timings derived from 240Hz ULMB at this time, but theoretically those should work too.
