Screen resolution

Forum thread started by civ247 on Sat, 2011-01-08 20:50

HI I have a large screen with a stanard resoluition of something like 1900x1200.

The "screen" app only allows up to 1280x1024 which makes everything look quite poor.

I understand I may be able to change this during bootup by holding "space" or "shift" and specifying manually however I cant get the boot menu to come up.

Any ideas why? Im using GRUB to boot.

You actually hold down [SHIFT] key or keep pressing on [SPACEBAR] key right at very start of Haiku booting. Soon as you select it in Grub and press [ENTER] key. Before you even see the Haiku boot screen.

Haiku uses VESA modes for unsupported video cards and these are determined by your video BIOS. You may not have any other modes to choose from. Are there higher resolution modes in Preferences->Screen? Are you using Intel graphics?

Hi,

Thanks for the response - I was able to get the menu and select someting like 1450x800 but im not sure its worked - it looks the same.

Im using an ATI graphics card Preferances -> Screen only allows 1280x1024 or smaller and it only allows the regular 4:3 aspect ratios i.e. 1280x1024, 1024x786, 800x600 etc

The vesa driver doesn't support 16:9 very well. I can't get my hd5770 to do this properly either. works fine on my 19inch 4:3 monitor however.

Ok, I thought Screen preferences might show 16:9 modes. I guess not. Computers I use for Haiku have Intel graphics and I only get 4:3 modes so couldn't say myself.
