[rescue] SPARCstation 5: framebuffer resolution wont change

[Peter Stokes]

Hi

That command looks to be correct for the card.

Curious why you need that resolution?

Are the monitors multisync ones that you are using, if so then they should
sync to any freq unless out of range of course?

I have never used that resolution change on SS5 OBP, but can confirm it works
on Ultra 1 systems with TGX card.

I would suggest trying it temporarily with a modern multisync which can cope
with higher sync/resoltion than the card and see what happens.

at the ideal resolution for my set up 1024x768x60 I do get no picture at all

visibility around the screen of about an inch when set at 1152x900x66.
