Talk:VESA BIOS Extensions

Misc
Some of these Linux mode numbers dont work using grub> vbeprobe prints says vbe 3.0 and a hole bunch of different mode numbers which then you add 0x200 to get the linux mode nuber and they clearly are different if these are wrong or OEM dependent then it useless having them -- 58.28.213.164 09:31, 26 September 2007 (UTC)

Booting at high-resolution?
In Linux, you can use like vga=794 to boot at 1280x1024. Would it be possible for someone to make a BIOS that boots in 1280x1024 from the start, instead of the old 80x25 mode that still all computers boot today, even though its heritage from the first computers? -- Frap (talk) 19:01, 19 March 2008 (UTC)

Neutrality of "Warning" section
This newly-created section contains a lot of Wikipedia no-no's, including first-person point of view (see Pronoun) and original research (No_original_research). I don't want to just jump in and delete it, as such a section may be of some value to the article, but in its current state it significantly detracts from the quality of the article, in my opinion. I'd appreciate hearing any suggestions on how this section can be improved and properly included in the article, if at all possible. 71.99.18.88 (talk) 21:03, 13 October 2008 (UTC)

Negative tone
The tone of the first paragraph is that VBE was not as succesful as it could have. While that is true, now, 10 years later, many Linux, and probably XP+ too use VESA as default driver, even if only for installation purposes. I think this could be added

Off-Topic Information
This page should provide details of the VBE standards, and should not contain much (if any) information that is not about these standards (including information about any specific implementation of the VBE standards). "5 Modes available in Parallels" should be deleted or shifted to a page about Parallels (unless someone wants to add hundreds of similar sections, one for each other emulator and one for each video card).

Details about how to setup a Linux kernel so that it uses high resolution video modes during boot is entirely irrelevant here, and "4 Linux video mode numbers" should be deleted or shifted to a page about Linux. —Preceding unsigned comment added by 58.170.109.1 (talk) 05:35, 17 April 2010 (UTC)

UniVBE
Would a link to UniVBE be appropriate for this article? That was software to update the VESA BIOS support of video cards. Bizzybody (talk) 09:48, 30 March 2011 (UTC)

Unfulfilled wishes and the future of the VBE
Most of modern cards comes with a primary and additional with a secondary display device, but only the primary display device can be used with the VBE bios.

Wisches for the future: - to show the content of the second LFB on the secondary display device, so that both devices of one card can be used, each with an own resolution and each with an own CRTC-Parameter Table

- a DDC-Read-EDID for the secondary display device

- an option for to handle if we become a clone-mode, multi-mode, or a span or extended mode — Preceding unsigned comment added by 85.177.18.65 (talk) 08:20, 6 December 2013 (UTC)

Any information about VBE 1.2?
Why is there no information about VESA BIOS Extension Mode 1.2? What does version 1.2 allow? — Preceding unsigned comment added by 37.209.89.166 (talk) 02:59, 10 October 2014 (UTC)

Colors
I tried looking for a citable answer to these questions to no avail. In 16-color and 256-color modes what are the color palettes? 18-bit such as VGA, 24-bit true color or something else?

As for 15-bit 5:5:5 and 16-bit 5:6:5 modes, I take it that for analog output there are in fact 2^5 red gradations, 2^5 or 2^6 green gradations and 2^5 blue gradations. For digital output are the values quantized to the nearest 2^8 R/G/B value?

What about 16-color 640x400 mode?
This is a graphics mode available on the NEC PC9801 computer, and possibly the NEC PC9821 as well. I'm also pretty sure I saw it listed somewhere else on the internet on VESA specifications. But the diagrams here on this Wikipedia don't show this as a VESA mode. Can somebody here verify if this is a legitimate VESA mode? Benhut1 (talk) 05:17, 20 February 2023 (UTC)


 * I think that's a standard VGA mode, not a VESA one. --Zac67 (talk) 07:36, 20 February 2023 (UTC)
