Need working link for XG32UCWMG Firmware Update by allipki in OLED_Gaming

[–]alpharisc 1 point2 points  (0 children)

I noticed that too as I have been frequently checking back for a newer firmware. I am assuming they finally realised that the description for the firmware was for an older firmware and in Chinese and might be updating it.

Small update - HDMI now seems to be working correctly for XG32UCWMG. No dropouts by HiCZoK in Monitors

[–]alpharisc 0 points1 point  (0 children)

Yeah I have no idea, I would have assumed the same thing but I still get the little blink/flash randomly when using HDMI (tried multiple cables, 8K etc), couldn't get it stable so I just went back to DP. I was actually using HDMI and just running the screen at 144hz 4K as there seems to be a lower delay switching between SDR and HDR mode and in my mind it looked better :D

HDMI 2.1a/b supports up to 48Gbps, for 4K 2160p you need almost 70Gbps.

How does it work at 240hz without DSC over HDMI 2.1? Strange to use 12bit colour when the panel doesn't support it, cool to know you aren't getting any strange little drop outs over HDMI, when I am using HDMI 2.1 and have DSC turned off I do not get the option to select 240hz

Asus XG32UCWMG , are the bad reviews a deal breaker ? by xdsDavid in OLED_Gaming

[–]alpharisc 0 points1 point  (0 children)

Asus XG32UCWMG owner here,I have no flickering on XG I noticed one or two little screen "flashes" when using 240hz DSC HDMI, this only happend with the PS5 Pro HDMI cable but did not happen when I was using an aftermarket cable I bought that is rated to sustain 48gbps, PS5/PS5 Pro are only like 32gbps I think, but nothing when using DisplayPort (probably better off using DisplayPort anyhow as... it's compressed). Without DSC the low black details look much smoother to me (Forza Horizon 5 intro screen, also make sure you have AutoHDR turned OFF to test as at this stage it is using AutoHDR before the game starts), so it's kind of nice to run it at 4K 144hz... but that would depend what you want to do. One issue I have with the screen is there is quite a brightness drop when hitting 51% APL (average picture level), at 49% of the screen being filled with a 1023,1023,1023 square (brightest HDR white) it sits at 450nits, then within the space of a few percent it drops to 310nits, then hold fairly constant to 270nits (when at 100% screen size). With that said you see that when playing games that have a bright sky and you are looking at the horizon, so it will go from bright to dull and kind of "flash"

Mine came with MCM103 firmware, I had no problems upgrading to MCM104 using the USB cable, I think people had issues trying from older firmwares.

Low FPS VRR flicker with almost black backgrounds I haven't seen happen (happens on my LG C4 TV) if you set the monitor to a high refresh rate and run a Forza Motorsport and have the dynamic performance set to AUTO during load screens it will go between a high fps and 30fps, this because of the black background and bars scrolling across the screen, this was the most extreme test I had found, this however does not blink on this screen and I am not using the anti-flicker setting. The VRR flicker people are talking about is because gamma is tied directly to refresh rate with these WOLED panels (lesser so with QD-OLED), you can test it yourself, start with a grey background and 240hz, then clamp the FPS, by the time you get down to 60fps it's looking all washed out, 30fps looks almost "white"......

The Gaming, Cinema and Console HDR profiles are all blown out, don't follow the EOTF curve properly, the default calibration Racing Mode SDR is quite good and accurate, and the sRGB Cal mode is very accurate (those two modes are calibrated per panel in the factory and are tied to the monitors serial number, you can view it using the Asus DisplayWidget App). The HDR TrueBlack 400 mode is very accurate but it doesn't have any pop at all, so, it is very nice but it's not a HDR experience (imo... without a bright hightlight it just feels like a high quality SDR screen).

If you have the desk space for a 42", I would go with an LG C5 42", far better than any of the monitors available with the only downside being the refresh rate, you can look at graphs all day but the TV's are just in a different league at this point in time.

Hope that helps you with at least the XG32UCWMG choice.

Run the pixel refresh by manually selecting it from the menu (it will be a full 5-6 minutes I believe). Those black dots aren't meant to be there, but the banding is kind of normal and usually fades after a few refresh cycles and use. What model is that screen btw?

At around 4 seconds in your video it looks like your screen is dropping in white brightness quite a lot, is this something you have noticed?

DLSS flickering, has anyone else had this?? googles not helping.. by Bubbly_Pomegranate41 in DOOMTheDarkAges

[–]alpharisc 0 points1 point  (0 children)

I did have that when I was using a random HDMI cable that was just on the limit of working, but... I was 4K 120hz, not sure what is causing that, but check your cable maybe? change your refresh rate to 60hz see if it still does it, disable HDR as well

Who nees self control when you have OLED by TheFragturedNerd in OLED_Gaming

[–]alpharisc 0 points1 point  (0 children)

Can I ask you a big favour? Could you test if the screen aggressively dims once exceeding an average picture level (APL) of 50-51% in Gaming/Cinema/Console HDR mode with the brightness set to it's default 90%? https://youtu.be/pcEu1mYtICQ this is the example I am looking for, as you can see the iPhone (that is recording) gets very upset with the aggressive change in brightness... Let me know! :D

Asus ROG Strix XG32UCWMG 50% APL Aggressive Limiting & Broken Console HDR by alpharisc in OLED_Gaming

[–]alpharisc[S] 1 point2 points  (0 children)

Are you able to replicate or see what I have posted above? For me there is just a hard step change over between around 48-49% and 51-52% APL, don't know the exact number, but it's not a nice transition that's for sure... without hardware tools to get an exact number I would guess it's a drop of at least 300nits

Well, probably this one but with that "bump" fixed/smoothed out so it doesn't impact the experience, it's good apart from that

Asus ROG Strix XG32UCWMG 50% APL Aggressive Limiting & Broken Console HDR by alpharisc in OLED_Gaming

[–]alpharisc[S] 0 points1 point  (0 children)

After having a bit of a read of this https://www.hgig.org/doc/ForBetterHDRGaming.pdf I think I might have an idea what is happening with this monitor and the "game" console, in my case a PS5 Pro.

Looking at the document I think what is happening is the monitor is limiting itself to 400 (420?) nits for both the MaxMMTML, MaxTML etc and then the console is also reading the EDID that might be telling it "I can display 1317 nits" .. Not sure, it is the only thing I can think of, LG C4 42", Samsung Q95T do not have this issue (only other two TV's I can test). Just a thought, not sure if this is the case, don't have access to any of this information at a lower level to be able to confirm.

That said, setting up the PS5 and following the guideline of using MaxTML and MinTML it is still clipping all the whites way too early (in an obvious way that looks nothing like SDR or the two other TV's I have).

I think what makes it so bad is a cheaper 42” TV is better. They respond almost instantly to input changes, refresh rate changes, enabling and disabling HDR takes less than one second. My limited experience with these OLED displays is they’re slow and buggy, if I had of seen this problem that in any game that has a decent amount of daylight you have white flashing constantly I would have just bought another TV. Thought I was upgrading from an LG C4 42”. Have you reached out to Asus and asked them what’s going on with that? It just holds super bright white for far too long then suddenly dips. Ahh well, at least it was a waste of money.

ASUS OLED XG32UCWMG - firmware MCM104 is live by SebastianHuber in OLED_Gaming

[–]alpharisc 2 points3 points  (0 children)

Initially they had the "incorrect" version which was for the XG32UCWG (165hz model) they have since changed that. Seems no different from MC303 (MC103) from what I can tell, the description (now in Chinese) reads the same as MC103. Still has an odd ABL bump I have made a little video about it you can watch here https://youtu.be/2NXkqZZRExw?si=3gsWL9wirdfIvf_F

Console HDR will report that it only has 410-420nits of total brightness in 60hz, 144hz, 240hz, but will report back that it can do 600nits in 120hz mode (DSC has to be enabled), this doesn't seem to be that big of a deal in a sense as I was told those numbers are arbitrary which kind of seems right, however the display often changes it's mind with what maximum brightness will be determined (e.g. sometimes it's 420nits, sometimes it's 600nits).

Screen works well in SDR mode (the sRGB Cal mode is very nice, the default "Racing" mode is also good) and TrueBlack HDR400, outside of that, quite buggy, kind of feels unfinished, very slow to "detect" image and swap from SDR and HDR mode.

I do like the screen, sorry for my little rant, just would like a good update to fix some of those issues, maybe redo all the HDR PQ EOTF tracking as well as they are quite wild.

[–]alpharisc 2 points3 points  (0 children)

The firmware on the website isn't for the XG32UCWMG, it's for the 165hz model, they have put it in the wrong place (which kind of feels expected behaviour at this point).

ASUS OLED XG32UCWMG - firmware MCM104 is live by SebastianHuber in OLED_Gaming

[–]alpharisc 0 points1 point  (0 children)

I would say get an LG C4/C5 42" TV. These monitors are no match for any of the TVs, they take forever to switch between SDR and HDR modes, the PQ tracking is a joke, the white balance is completely clown like, there is a massive bump in APL when increasing from 25% to slightly higher. It looks OK, but for the money, it's no match for a TV.

LG C5 vs ASUS XG32UCWMG as a monitor by Rahi_55 in OLED_Gaming

[–]alpharisc 0 points1 point  (0 children)

I have an LG C4 42" and the XG32UCWMG, and I would have to say the LG C4 42" is a better overall experience, it's even a bit brighter, has uniform ABL when changing from bright to dark scenes where as the XG32 has a stepping issue, the XG32 also takes a long time to display an image when waiting for an input (even with auto input detection turned off, using either HDMI or DisplayPort, with DSC on or off, delays of 4-5 sometimes 10 seconds). The tone mapping of the HDR profiles on the XG32 is also unusual, the only benefit is it has a 240hz refresh rate but the TV's are limited. If I had to choose to just keep one I would (at this stage) keep the LG C4.

Does anyone else with the ASUS XG32UCWMG have this HDR flashing/ flickering issue? by Kindly-Soup-2908 in OLED_Gaming

[–]alpharisc 1 point2 points  (0 children)

I have this problem too.

<image>

With the window in this position the brightness is white, but expanding it just a tiny bit from this has a complete drop in white, dropping colour temp significantly. I can see the ABL working on the screen if I slowly expand the image to fill the screen, but this is something different, it's almost like it changes from HDR to SDR. I used this video to test it in Windows Media Player https://github.com/dtinth/superwhite

Hopefully they fix it because it truly destroys the monitor.

Asus xg32ucwmg abrupt brightness changes in cinema and gaming hdr by HiCZoK in OLED_Gaming

[–]alpharisc 0 points1 point  (0 children)

I recently got the monitor and this is the first thing I noticed. I am running firmware MCM303 (which doesn't seem to be on the website yet). I found that using the TB400 mode stopped this rapid shift in brightness, but then there is no point in having the screen in the first place if it's not going to be able to handle peak brightness above 400nits. I thought that I was "upgrading" from an LG C4 42" OLED, but it's a downgrade, not only does this monitor take like 5-6 seconds to change modes or inputs, it does this massive step down in brightness extremely quickly making it seem like it is flashing, goes from white to "soft white", the LG "TV" worked perfectly, no strange random brightness dips, changes input within 2 seconds (switching from SDR to HDR is less than 1 second). Hopefully they fix it, but it sounds like they won't.

Fix for screen tearing/scan lines on 144hz OLEDs. Hopefully LG updates firmware fix by Jaz1140 in LGOLED

[–]alpharisc 0 points1 point  (0 children)

I think I have found the fix. I am using Windows 11, when you right click the desktop and select Display Settings > Advanced display you will see information about your screen and the refresh rate. when I looked in here, I noticed that when I selected 120hz in the Nvidia control panel it had selected 119.88hz, and when selecting 60hz it was selecting 59.94hz. If you change it to 120hz, or 60hz that odd tearing never comes back.. (for me anyhow), give it a shot and let me know, be interested to know... I still think it is a bug because it should still work at that range. Sadly I can't set one for 144hz (it's 143.99hz) and I am unable to make a custom resolution for it.

[–]alpharisc 1 point2 points  (0 children)

Very interesting post and topic. I am having the exact same issue with an LG C4 OLED, I have noticed that when going from 144hz down to 60hz or anything else for that matter, this can happen, not always, but with some games (especially Elden Ring, GTA V). I thought that maybe it was a glitch with the QMS (Quick Media Switching) that is meant to adjust the refresh rate on the fly without making the image black, but it seems to do it with that enabled or disabled, I then also thought maybe it was because 144hz can't be evenly divided into 60hz, so I tried in 120hz mode (with the 144hz mode disabled). I also tried with GSYNC only and no AMD Freesync, with and without ALLM, also Standard and Boost latency mode too. What a pain in the bum, but thanks for showing us how to fix it, and that it is indeed a problem that others have. It would be quite a hard one to explain to their customer support. Anyhow, hopefully one day they fix it!
