Lost 2560x1440 with Radeon RX580 on X5000

** Update
OK, got it manually now.

got it... finally. Sheesh.

Will add 4k later to my manual settings but for now, after twaddling and finding some notes I made long ago (amazing I found them haha) that I needed to set Hsync higher than I think what seemed normal at the time. hahaha.

Hsync coming in at just under 89...88.86 khz so I set manually to 89 and vertical at 60 and boom, 2560x1440 shows now

Now will I be able to do that for the 4K. haha

That is for tomorrow.

Thanks for the ears all.

Original message...

The video will show you what I am experiencing. I seem to remember getting this mode to work on my HD7750 and this TCL 43" 4K TJ was tricky but did get to work and has worked for years.

I am not sure what setting I am not checking or saving or why I can't save my ScreenMode now for the faken resolutions, but maybe that is the issue?

Please see this video.

Any advice would be great!

I prefer 2.5k as nicer than 4k on my eyes.

1080p and 4K work great, but I have lost 2.5k.

So the reboot thing - you're just discovering the one downside of the RX series of card which maybe we forgot to mention (oops?)!. You can't warm boot them. It has to be a cold boot. Fortunately, there's a key combo that does a cold boot for you so while I initially didn't like the idea, in reality, it hasn't cause me a problem.

So if you use CTRL-Alt-Alt rather than Amiga-Amiga, you'll do a cold boot. The downside is obviously you have to sit through the animation every time.

Start off with that, I would think you wouldn't need the fake modes, you ought to be able to just save the monitor with the manual modes listed where you've added your 1440p, reboot and then you should be able to select it...

It did the same thing to me years ago when I purchased this TV and went 2.5K. You clearly see it in the one tab but never shows in the available. The setting was already there as well as it is the same screenmode that I left it at before the card switch.

Nice to know the Ctrl Alt Alt but that does not take care of the immediate issue, that 2560 x 1440 never showing in available screen.

Weird it is.

Thanks for the notes Martin.

Has to be some setting I don't have right or just not saving it. And clicking save and hard reset I have the same settings before the save meaning no faken checked, even if maybe not needed.

In my quest to get 1440p on this 4k TV, again been using it as 1440p for years on my Radeon HD7750 and made zero changes to my Screenmode prefs, I would think the new RX580 that can do 1440 should have just worked. Since it did not, I set AutoDetech on and it offers all less 1440p.

So, connect to a REAL computer monitor, an HP Open 32" that does up to 2.5k, but comfortable at 1080p as well, yet Screenmode on AutoDetect does not even see past 640x480? What?

See attached video.

Confused.

Maybe my ScreenMode prefs that were perfect for a Radeon 7750 need to be wiped out and a new one created named Radeon RX580 or something?

I am blind to that and figured things should have at least shown 1080p on a real monitor yet seems bogged down to 640x480 as the video shows.

Thanks for the ear,

TJ

One more video just in case this all goes back to an old 2014 Radeon HD 7700 Series in my Devs Monitor. Maybe this one needs to be altered, or made new?

Lastly, for those following along, I also renamed my and also replaced too as a last resort the Devs/Monitor to various names just in case after seeing the name of the GPU in Ranger.

Tried RadeonRX, Radeon RX, and Radeon RX Polaris10

No advancing and getting 1440p as an option and on that real HP Omen 32", nothing past 640x480 using Auto Detect.

Stalemate for me as of now. May just have to go 1080p or 4K. haha.

Maybe a setting in manual for 1440 is off on mine.

Going to see about downloading the TV manual and see what syncs it has as maybe I need to adjust those for the manual setting for 1440 to show. That is next. haha tj

I am away from my X5000 but I can remember that somehow my setup was also not able to display the resolution that I want. Iirc this has to do with some limitation within the gfx library. For some weird reason, my 3440x1440 only shows up at 61Hz and not at 60 Hz. So maybe you play with the refresh rate for your 2.5k resolution as well.

Thanks. Yeh been playing all morning. Had tried 61, then 62, etc... so far I have not found one that works. haha

I have a TCL 43S515 TV, which is a 4K TV.

Ranger shows VSync min 23 and max 76 so I changed up to 76 in Screenmode but no go. Then tried 61 I think.

I have tried so many variations I go lost where I last ended. haha

HSync is 15000 min and 81000 max.

Adjusted those in ScreenMode but still, that 1440 eludes me.

So odd it worked fine on the Radeon HD7750.

Maybe just an issue with my new RX580?

Anyway, I will keep tinkering but so far seems 1080p may be what I have to use, for now. 4K is just too small for my eyes and seems Workbench skitters around in 4K and does not seem right for me, clunky maybe even.

Thanks for the tip.
