im using amd 270x and able to add 2560x1440 @ 60hz. my lcd tv is 1080p.

since i want to play games with 30hz refresh rate, i successfully add new setting 1920x1080 @ 30hz, however if i add 2560x1440 @ 30hz, the image shrink (vertically-big border right and left screen).

is there anything i can do to solve this issue. tq

If 2560x1440 @ 60 Hz works, try using the same timing parameters for 30 Hz. "LCD native" uses the 60 Hz timing parameters for all refresh rates. If that doesn't work, then the TV probably can't handle 2560x1440 @ 30 Hz properly.

I'm not sure why you'd want to play games at 30 Hz. 60 Hz should have less tearing and lag at lower frame rates. If you want to use vsync at 30 FPS, use 60 Hz and set a frame rate limit instead.

it mean i need to manually insert all parameters including front porch, sync width, etc?

i can't run my games perfectly using 60fps thats why i wanna try setting 30hz refresh rate using radeonpro. if i set 30hz in radeonpro, it will reduce to 24fps cus current display setting does not include 30hz. i guess that is why game select 24hz instead.
after i use cru by setting 1080p@30hz, it work fine. now im gonna try 1440p@30hz.

fyi, frame limiter works fine in 2560x2440@60hz, i just want to study is there any different if i use 30hz + 30fps limit + without vsync

Just IMO, but,
There's no benefit to capping a game framerate that low.
If you try using vsync at 30 hz refresh rate, your game will be completely unplayable unless you're using a console controller on a console port. You're going to have at *least* 33ms of input lag just from the vsync+30 hz/30 fps alone. This is assuming vsync is on. the real input lag will probably be -much- higher.

Vsync off and 30 hz with a framerate cap isn't going to be much better. And you're going to get a blurry mess when turning.

Just use 60hz. There's absolutely no point at all at using 30hz or capping your fps at such a low value.
