I also purchased a decent brand adapter yours but you have to make sure the card you use has the right height, etc... so it can plug in and mount screw-holes to the case so it stays in place and not wobble. Maybe a 1/2 height type of video card is designed to plug into the extender and then mount all properly?
I was just gonna connect the extender, then plug a long extender cable into that and mount the full size video card elsewhere but that extender was wobbly and nothing locking it in so I moved onto that 4x slot and proper cable like mine where I could plug it in and mount the video card elsewhere.
The cards that work with MOS were harder to find one that for sure works, all are used, and luckily my case has a full slot I could run an extender cable too.
Depending on the orientation of your 2nd video card, mine was done in a Thermaltake case where the 2nd card is being connected to a certain bracket, this type of cable is what I used. Just match to the proper orientation so your 2nd video card can plug in properly, etc...
I think mine was the R23SF-TL the way I needed it to screw onto my mounting bracket and the video card pop out the back of the case right.
You may need to, or best to, install the OS with your older video card, then update the Expander that has newer drivers, that way old and new drivers present, and then install new video card so it can use the newer drives and you get video.
There may be a way to move things in as you do BUT I don't know how to do that so I upgraded my Expander while the older video card was in, installed my new Expander to newest version, then made the hardware change, and all seemed to work OK for me other than the oddball losing of some resolutions I prefered 1440p, etc.. that I had to play around with to get back.
I like my RX580 very much by the way. I also have multiple drives in my X5K, an older HDD that has all my old stuff that I can boot from if needed and an SSD that is my newest boot drive. Plenty of space in my case to have several drives.
Wow, had no idea a 1200 monitor file could even work on an Amiga OS 4.1 X5K. ‘
Glad you found a solution.
You could always switch back to the one that had the 1440p working and write down all the settings and then switch to the one that works good for your 1080p and add a 1440p setting using your known good settings.
Like I do, you may want to make a video so folks can see what you are seeing. Otherwise it may be lots of shots in the dark guessing.
I find the whole Monitor Selection in Amiga OS to be a bit of voodoo. From needing the right drivers, Enhancers, blah blah blah.
You may want to let everyone know your full specs on the machine, version of the Enhancer and drivers and all of that.
For me, as shown above, I could not get 2560x1440 but 1080p was fine. But I had to manually add and play with those sync settings to finally get one to work.
So many factors, so many monitors, all allowing different sync etc..
I am so novice at Amiga and the OS and think the only way I got mine back was so many trial and error, taking any advices here and elsewhere, and trying them all.
But a video of your step by step showing you selecting your monitor settings and all that and knowing your version of all may help folks here offer ideas.
Odds are I won't see much (as I am novice) but maybe I will see something.
But again, I had to manually add one that FINALLY worked, adjusting my vSync and HSync where finally one worked. Was just luck I think. haha
I now have Amiga OS and MorphOS on my X5K and my main keyboard I use, a nice RGB keyboard, won't allow me to even get into the early boot menu. ESC don't do it. I have to leave a really cheap $7 keyboard connected to my X5K to hit ESC to get to that early boot menu. Once booted, the nicer keyboard works but won't work for the early boot window.
Must be some oddball USB thing. Maybe it needs too much juice to keep the rgb lights and conks out on early boot. haha
Of course even if early boot comes up automatically, unsure if my nicer keyboard would work or not.
The Finish (or is it really the Starting) Line of my AmigaOne X5000 Dual Boot Computer, booting Amiga OS 4.1 and MorphOS 3.18 for the (kind of) First Time. My guess this is really just the Starting Line for me as MorphOS looks quite nice!
Adding a 2nd video rather than start a 2nd thread.
Dual Boot now up and running from internal drives and I chat about the process.
Just installed it yesterday onto my hard drive. Took some coaxing to get that done. Think install on a dual-boot takes some voodoo and help from others like @skateman to get it done. Manually partitioning the drives seemed to be a point of contention but finally, I think by some luck, some good advice from @skateman, and me trying to throw all things at it approach, one finally stuck. haha.
But now that I have it on there and a 1920x1080 rez after that was an issue, I will explore it some.
What I can say is, limited testing, Wayfarer is a nicer browser for internet AND my limited testing of Google services worked. I could do my google mail, google drive, and launch my calendar. All slow compared to a linux or Mac but it did work. My X5K using Amiga OS and Odyssey just plain could not work with those google services. Therefore, out of the box, that is nice!
Also, out of the box, I could access my smb based NAS from MorphOS 3.18 and grab a file from it. I recall I tried that on Amiga OS 2 years ago and could not get past installing the app that added that and could not get that to work. In MorphOS, it just worked.. SLOWLY but worked.
That 300mb file took 7 minutes so could be my old Nas or maybe speed of ethernet on my X5K?
This is stage 1 of my efforts to make my AmigaOne X5K boot both the Amiga OS 4.1 and MorphOS 3.18.
This is the 1st video about my plans, my system, some peaks inside, and 1st boot (from MorphOS Installer USB Stick) after installing a 2nd Video Card in my X5000.
I can't imagine there is much difference between a 5020 and 5040. With the extra cores not used on either, that 200 Mhz is nominal but I only own the 5020 so can't say for sure, but unless extra cores start getting used, and apps using the extra cores, I don't think there would be tons of extra speed. Just my 2 cents. TJ
