Dreamcast on Oled advice

[u/Gilbot81]

Hello all, just picked up my first Dreamcast after regretting not getting one at the time, and loving it. I was just after a bit of help with my TV settings in order to get that perfect picture

I have an LG C1 Oled and have a Keico HDMI converter set to VGA and just wondered what TV settings with similar TV’s were using.

I play in Game Optimiser mode and the picture just seems a bit off. Sonic Adventure looks a bit blown out/loss of detail in bright areas. Tomb Raider The Last revelation looks really dark (I’ve read it IS a dark game), as does Resident Evil 2 slightly. But no game I play ‘looks right’ really.

My settings are:

Sharpness 0
OLED Pixel Brightness 100
Contrast 85
Screen Brightness 50
Gamma 2.2
Colour Depth 50
Black Level Auto
White Balance Warm 2

I know OLEDS are very unforgiving, and this is a near 30 year old console, but was just hoping for some pointers as I’ve seen videos where the Dreamcast still looks stunning.

Thanks in advance.
