Hi, I’m coming back to Haiku after being gone for awhile. Last time I had a Nightly slightly newer than the R1A4 “public” build and had no problems. Everything was running fine and with correct resolutions / refresh rates. Installed latest nightly and it didn’t work anymore.
I had a lenovo desktop computer with (I think it was) a E8500 CPU and a Radeon 4550 card connected via HDMI to an Acer MT230HM TV/Display @1920x1080x60Hz.
I upgraded the computer to a similar lenovo, but with an i5-2500 CPU and stuck that same graphics card into it, connected to the same monitor via the same cable. Turned it on and it started fine (displayed loader) and then black screened. I though, well, might as well start with a clean slate rather than fiddle with settings after upgrading the whole computer… Anyways, downloaded hrev49416, installed via USB disk (worked 100%, formatted partition and made a clean install). Booted up the installation and everything worked fine, albeit at 1280x1024 resolution. So went to Screen and set it to 1920x1080@60Hz, hit Apply and was greeted by a “Not supported” black screen on the display. I went Huh?, though I forgot and tried with email@example.comHz - same happened. While googling on another computer which is the right Hz I figured I’d put that into any 16:9 res to get rid of wonky UI. Went with 1380x768@60Hz and lo and behold it worked… but the monitor displayed its own onscreen UI as 1366x768@75Hz! 75? I didn’t set that to 75… tried changing it to 55 - monitor displayed 75. No matter what I try, it ALWAYS goes to 75Hz.
I believe my problem now is, that my monitor does support FullHD@60Hz, but that Haiku sets it at FullHD@75Hz, which it doesn’t support.
Is there anything I can do (fiddle with config files anywhere?) or am I just stuck waiting for “someone” to fix this in a later build?
