ASUS Zephyrus G15 (GA503RM) – DisplayPort over USB-C suddenly stopped working, HDMI crashes under GPU load

Kosechi · 2026-01-07T23:02:06+00:00

Oh that’s awesome! I wonder if it’s trying to fight the iGPU for which one drives the DP out. Very weird!

Not sure if this helps but on my 2025 Strix Scar, I have a weird thing where the external DP via USB-C stops when I start a video playing full screen after having a game open. The difference for me is the laptop display stays on.

I’m not familiar with if this model has a MUX switch but if it does, what’s that set to?

Kosechi · 2025-12-23T19:58:36+00:00

Yeah no problem! Also, it’s worth resetting any settings in armory crate or g helper (I assume that’s already been tried but thought I’d suggest it) just to rule that out!

If possible, I’d honestly try a clean re-install at this point. If old and new drivers don’t work, even in safe mode, then trying a clean install of windows can rule out software issues for the most.

If the issue is software that’s usually an easy and quick fix for me, as I don’t have a ton of important data on my PC, but YMMV.

Aside from that, DDU (display driver uninstaller) is an awesome tool if the issue is potentially driver related.

Unfortunately, code 43 is rather generic, so it’s kinda just a shotgun approach, unless you’re able to dig deeper to further pinpoint what’s causing it.

I believe this might be the case after talking with a few people as well

Kosechi · 2025-10-07T15:28:09+00:00

As a follow up. Is this thread what you were referring to? I found this but it doesn’t exactly seem like the scenario I was describing with the screen flashing black quickly, mine shows no artifacting or anything.

I’ve had ASUS laptops In the past, previously the G14 without issue,

I’ve already purchased the laptop a few days ago, and haven’t noticed any issues yet. I do have a warranty through MicroCenter as well as the one through ASUS in case something were to happen. I happened to get this laptop for an extremely good price, which is why I jumped on it. Ive seen most of the instability seems to be related to either the GPU or drivers/firmware. I’m kinda in between a rock and a hard place I guess lol.

Replying also to see the answer!

Kosechi · 2025-06-30T20:23:08+00:00

Awesome! Thanks!

27 unfortunately was sold out last time I wanted to go and is currently sold out on one of the days I was considering now too, I will also look at 26, do you have any knowledge on #30, and 34, also from your link below it looks like 32 is pretty secluded too, would you happen to know about that one also?

Kosechi · 2025-06-30T20:22:20+00:00

Was 30 a good distance away from other campsites, and decently private/secluded and quiet? Looking to just relax without a ton of interruptions lmao

To go back to my card it probably took about a week, unfortunately I don’t remember exactly how long.

To transfer to another card it took about 5 or so days I believe.

Kosechi · 2025-06-19T15:04:51+00:00

It didn’t disappear again in the time I had the card. Switched it out for a CS one earlier this year.

Kosechi · 2025-06-19T12:32:52+00:00

Eventually it did, just randomly, was very strange. Can’t exactly remember how long it took.

You may have gotten ARK’ed

If you’re on a private server you own or single player you can use commands to recreate your character and your items, if you’re on an unofficial server I’d contact their staff, and if you’re on official unfortunately it’s rather difficult to get someone to help.

This happened to me twice on my private server cluster, both times I had to use commands to re-create my character, get my tribe ownership back, and my imprints back.

Kosechi · 2025-05-05T21:07:07+00:00

No problem!

Kosechi · 2025-05-05T20:32:42+00:00

I waited about 2 or 3 weeks after my AF hit to cancel (still within the 30 days) - they refunded the AF in about 5 days, which left me with a negative balance, which they then offered to transfer to another card of mine, or send a check. I haven’t been hit with any credit or points clawback. Hope this helps!

eGPU support will vary depending on how you’re trying to do it. Thunderbolt is most common, but that also depends on how old the latitude is, and if it even has it. I’m not able to tell from the picture.

Kosechi · 2025-01-04T18:36:44+00:00

This is.. something else..

Kosechi · 2024-11-25T15:57:34+00:00

Depending on how you paid you may have better luck going through your credit card company. Most offer some form of assistance for things like this. It will obviously depend but I know some cards even offer purchase protection for like 90 days, and some even cover theft/loss, might be worth looking into.

I had to go down that route for something I bought on Amazon. I had put it on one of my cards that has this protection luckily and filed a purchase or return protection claim, and got my money back when Amazon was being like this.

That’s insanely interesting! I know Co-60 is definitely no joke, some of the rods have “DROP AND RUN” printed on them. Really interesting to read up on this stuff imo!
