This is really irritating the hell out of me.
I play my 360 at 1366x768 or whatever via vga, and it looks good at every resolution i choose. Looks great via Component as well.
Now that i have a PS3 i play via HDMI on port 1 (havent tried switching ports yet) and it looks very grainy in any res (on ps3 you pick 480/720/1080) ... the menus all look like a very very low resolution JPEG, and in 720p the edges of things are jagged and there are "Sparklies" as i've mentioned earlier in this thread. In 1080i the sparklies go away but the picture doesnt look as sharp.
Some games don't support 1080i though, like Motorstorm which came with it... it will only either do 480p or 720p. If i try to force it into 1080i it kicks back to 480.
I called Hannspree Tech Support to see if i could get someone to perform the firmware upgrade but the guy swore up and down that no such update existed and that it was ONLY plug and play.
He told me that it was my PS3, not the TV.
What should i do in this situation? It bugs the hell out of me...
I bought my HDMI cable through Monoprice.. its a 6' 1.3 cable.
I could also try Component but i'd have to fork over the cash just to troubleshoot it, and i would prefer it work via HDMI correctly anyway.
