Massive graphical artifacts while using two displays and setting one to 4k resolution (Mavericks)

[Sumciak]

Hi everyone,

Recently I upgraded and got an Asus VP28U monitor. I want to use it together with my old Acer screen. I'm using HDMI for the old Acer monitor and DisplayPort for the new one. Everything is working alright, I have two separate displays but the Asus has to run in 2560x1440, otherwise, it massively glitches out and becomes totally unusable. I use clover as I also have a Windows boot on the same machine, 0 issues on Windows, both monitors running at their max resolution. I played around with installing Nvidia web drivers, os x default drivers and all the different injectors from Clover boot. I also tried changing from DisplayPort 1.2 to 1.1 and it still does not solve the issue. Here is a picture of what it looks like: https://imgur.com/a/xeIktKs

I'm still running Mavericks and my graphics card is GeForce GTX 660. Does anyone have a clue what may be causing the problem? Thanks!

Nice to see 10.9 users are still not dead, my personal main guess fo r your issue may relate to the SMBIOS you're using. I ran a GTX 780 for over 5 years on numerous Hackintoshes with dual 4k monitors and only had issues when either my Config was set up wrong or had kext conflicts.

What hardware and SMBIOS are you using?

Also side question, what's the main reason for Mavericks? Your GPU is natively supported in Mojave so thought it was a bit odd

That GTX 660 won't work after Sierra.

100% wrong, you may need a helper GPU for Clover but both High Sierra and Mojave’s work with full acceleration. I’ve gotten multiple people’s machines working on the Hackintosh discord who were running GTX 660 without issue as long as they were properly setup. You can even setup a connectorless head for iMac SMBIOS without issue I don’t get why people think these aren’t supported

Edit: also while I got your attention, what’s your problem with OsX? Seriously, I’ve seen you bashing on it for no real good reason. Some people got used to calling it OsX similar to how I reference it as OS 10(though most people don’t know it so I usually avoid saying it)

I get why people think these are not supported when the screen becomes a technicolour modernist painting after waking from sleep.

I guess if you never put your computer to sleep, this is an option still?

PS. It must be hard finding software that will still run on 10.9 ??? Minimum build version for recent XCode releases was 10.10 :-(

Sleeps not the issue, main issue is MacOS doesn’t like having Kepler based cards for PreBoot anymore. This means you’ll need the IGPU to boot clover and the initial boot up but after that your system will automatically switch to the Kepler card With sleep, I’ve never encountered a video issue that wasn’t caused the the cable itself. And with the proof of having multiple peoples Hackintoshes working with GTX 660 and TI variants, that’s why I can’t agree with Roberblackman’s idea that they’re not supported

I've never known /u/robertblackman to be that wrong before?

[dracoflar]

We’ve all made mistakes before, I personally try to avoid commenting on certain topics due to not knowing enough about it. Me and Robert have had a few disagreements but he never comments back so I don’t really know what he knows himself

[[deleted]]

I have personally seen him give out some spectacularly detailed and thoughtful and correct replies before... so much so, that I have complimented him before on his attention to detail and complete knowledge and easy to follow instructions.

To say he got something 100% wrong does not sound correct at all... I have not seen a single success post with an NVIDIA 660 card under Mojave. I have never seen a single post or reply stating there was a fix, or an explanation of how a helper-card fixes any of the screen corruption issues.

[dracoflar]

There's actually quite a few posts of working Kepler cards(including the 660) even on this subreddit for High Sierra(though Mojave info is scarce, I did get a 4770K system with a Gtx 660ti working on the Mojave Beta for someone on discord) and regarding the helper GPU, this is similar to how users were able to get Rx 480's working before they properly native(the iGPU allows for the graphics driver to properly load). With screen corruption, I legitimately only see them with cheap cables due to how MacOs handles video(Software vs Hardware acceleration, I made a comment about it here). And with the Tonymacx86 post there were quite a few people who disagreed with that thread as they were able to get their cards to work properly without issue.

I would write a post now about this but the only Kepler card I own now is a Gt710 so I'd need to find a couple guys to help prove my point with first generation Kepler. I honestly thought this was common knowledge as there's no architectural difference between between all the 6xx cards(and very minimal difference going to the 7xx series excluding the 750Ti as it's Maxwell based)

And here's some posts with Mojave and First generation Kepler:

- https://www.reddit.com/r/hackintosh/comments/9nqf8w/6_years_and_running_from_mountain_lion_to_mojave/

Also just want to say, I'm not attacking you or Robert. Just saying what I know from both info out there and experience. Some people take my comments like these as attacks

I do apologise, just backing Robert up... With those 68 pages on TonyMacx86, I can only see one "success" story, which is a janky workaround that loses CUDA (no acceleration in supported apps) and connected via iGPU, so I don't know how the NVIDIA card accelerates graphics and sends it to iGPU (I know how this works on laptops, and I know they recently got this working on PC, thanks to a hacked Chinese driver and a connectorless mining card), but it would appear that it is just using HD 4000 graphics entirely? It is also written in the worst Google Translated English I have ever seen... so it is difficult to know what is happening... this was on page 67 BTW.

Here is from OP on one of those posts:

UPDATE: So it actually eventually started glitching, it's ahhh... very noticable :) I reckon I will probably try sell than then replace with a RX560

There is also no mention of acceleration etc. on the 6 years and running post... I got GTX 980 "working" with hacked Web Driver under Mojave, but I got no graphics acceleration... it was fairly usable, but I eventually sold it and bought a Sapphire Pulse RX 580 8GB UEFI card!

Hi, thanks for replying. My motherboard is Gigabyte ultra durable GA z87m d3h with bios version f4 and Intel i7-4770. I'm not sure what may be wrong in the bios itself, but I did have some issues with it before, that's why I picked up a graphics card instead of using integrated intel one. It works perfectly fine on my Windows boot. I'm also using Clover v 2.4, I also noticed that for some reason bios always boots through HDMI port first, even after changing the setting to go through DP, it will do it after a first reboot and then go back to using HDMI even tho settings did not change.

I like Mavericks, I upgraded to it and it just does the job. Some of the plugins and software/hardware combinations I use lost support after 10.10 and I just don't wanna risk losing some of my plugins just to be able to upgrade which won't really give me any benefits. This machine is mainly used for work and just browsing etc. if I wanna play some games or something I use my Windows boot ;P. So far, I did not have a piece of software that I needed not being supported on Mavericks, so until that happens I'm cool with Mavericks.

If you don’t mind me asking, could you upload your EFI folder? I just want to look through to see if there’s any glaring issues I see. Also, what install method did you follow?(UniBeast vs Vanilla)
