I use the 1024 mode on both my Samsung u28d590 uhd monitor and on our Samsung 9 series TV without any problems. I live in Norway so I use pal ofc.
I have another question though, asking it here if it's OK, instead of starting another thread.
I run os3.9 and I want to preserve chipmem, can I use fblit or another tool so the higher resolution doesn't eat up all my chipmem?
I noticed I have tried it, seeing the "simplegels" etc at the end of my ss, but I only have 900k chipmem after entering wb.
Any tips to this?
