The strange thing is, this happens even if I create and use a profile that has a lower refresh rate than 60hz (eg. 55hz) with the same resolution; it seems like my display is locked to 60hz and can't be increased or decreased. How should I do this?

You can't.

Damn.

Thanks for letting me know though

Hi,
I need help with choosing a timing.
My 1080p monitor work at 75Hz only with LCD reduced.
My question is if i want custom resolution 960x720 at 75Hz and it works with all three LCD timings which I should choose. Is there an advantage of using a lower pixel clock with lower blanking or should I use higher pixel clock if the monitor handle it?

It doesn't really matter. I would use "LCD standard" so the video card can clock down when idle. Lower pixel clock doesn't really have an advantage unless you're hitting limits.

hello

my 1st attempt, I copied pasted 1 single monitor settings with extended freesync 42-75Hz into the Eyefinity created via RADEON UI

it looks like an extension block was indeed created and frequency range is matching the single monitor one, and I can see 42-75Hz showing in the RADEON UI

but then I reboot and bang, its back to 48-75Hz so what have I missed then?

Did you paste to all the monitor entries? If so, I don't think you missed anything. It's probably a driver bug.

I am sorry i am not sure how to verify all this. I copy 1 monitor entry and it was fine

If i try the 2nd monitor it looks like it does add nothing in ectension block because it says 2 slots still available

You said you have three monitors. Did you paste the same configuration to all three monitors both with and without Eyefinity?

No
What i did is for each monitor just extending the freesync range to 42 75hz in the extension block section

2 monitors on side are dell same model and i have 1 acer as center

All are 1089p 48 75hz freesync spec

You mean i have to copy 1 monitor cru setting to the 2 others then create eyefinity?

Hi everyone and ToastyX offcorse! I had a big problem since 3 weeks, i dont know whats happend with my monitor. After tryng cru the first it was no problem, but i just wanna playing with gpu scaling anyways for afraid to damage, and so turn to default and i can make it, but 2ndtime with restart.all, uninstalling pnp monitor, restart pc or doing with 64. It figure its back to normal. But i have input delay right now writing this and playing is awfull, its working too bad. I did a vsynctester and
fluctuates all the time between 190 and 239 constantly. It is possible is broken? I check everything. And did a clean install windows(2004) after 1 week if i can fix it but nothing, could be bug with previous 1909 win? my disks are ok, cpu too, it could be good to buy another DVI cable? Thanks 4 listening! I really appreciate the support Peace for all (=

You said it creates new monitor entries when you enable FreeSync. Did you paste the configuration to the new monitor entries?
