Booting with HDMI-DVI adapter issues
Posted: Sat Jan 12, 2013 5:14 am
Hi everyone.
My question might be newbie or not I am not sure, I am not super proficient in linux OS.
Recently one of my friends was in need of a simple machine to watch movies and basic browsing on his bedroom TV. I gave hime happily my old fit pc2 (I have a V3 now) knowing that it would do a do job, but it didn't.
Here is the issue:
When booting with a HDMI cable everything is OK, the pc boots and al works, but when the HDMI-DVI adapter is used (the one originally provided) it freaks out, the TV displays an "unsupported resolution" error when reaching the desktop GUI (i can see the earlier stages of the boot).
I though it was a limitation with the TV (a weird Chinese model) but I the same issue using my high end Dell screen that support pretty much any resolution/frequency.
I thought the adapter might be broken, but if I boot on HDMI and then switch to the adapter it works fine.
As it was an old install I thought the drivers etc might be screwed so i took advantage of the newly released EMGD 1.16 and did the whole thing.
Success on the install but only marginal success on fixing the problem:
Sometimes now on the Dell monitor it works, but the resolution is locked to 1920 @ 60Hz.
I know the TV support 1920x1080 @ 30 Hz and 720 at many frequencies (selectable when I boot with the HDMI cable)
Does anyone have a clue on what it might be, or actually how to fix it ?
A few notes :
- Sometimes after failing a boot with DVI on the next boot I get a error message about some incorrect permissions to write a config file.
- Being in China Internet at boot doesn't always work straight away meaning I cannot ssh / remote screen into the box
- (related or not )I tried using a very strange DVI to YHB adapter, It kind of works but the resolution is locked to a very unusable value
thanks.
