HDMI issues

[dhardingham]

I also have tried a variety of monitors, TVs & cables. I got it to work HDMI > HDMI on a Dell S2740L. But it doesn't work on my older Dell 1920 monitor or a 2560 Dell Ultrasharp, or on my Samsung HDTV. Have tried 3 Linux variants.

I get the impression that whoever is developing the kernel drivers is doing it on a very limited set of hardware & hasn't even thought about supporting a sensible range of monitors.

If some Linux guru was able to write some scripts that would update the display drivers for a few common OS variants we'd be leagues ahead of where we are now. 

My Pine is sitting on my desk doing nothing now, useless until I can find a cheap monitor that I know I can actually use it with. The only reason I know it was actually booting up is by connecting a USB serial cable. 

I don't mind tweaking to get the thing going, that's why I bought it, but when you can't even get it to run a monitor it makes you wonder why you even bothered.

At least for the Linux images based on longsleep's kernel the issue of switching resolution is resolved, resolution can be configured via u-boot and theoretically switched on the fly while running Linux. See http://forum.pine64.org/showthread.php?tid=980

Unfortunately, this tool doesn't support 1920 x 1200. This is widely used by many high-definition monitors.
