This is just a guess, because I haven't used the HDMI connector on an Eee Box yet, but it sounds like you have a problem with encryption. HDMI signals support encryption (for DRM), so you have end-to-end protection when you play protected media. The signal is decrypted by the display, so there is no way someone can make a digital copy of the protected content. However, DVI does not support encryption, so HDMI-to-DVI cables only work for non-encrypted signals. Also, some computer monitors that have a HDMI connector do not support encryption. When you switch to an analog output, then encryption is not used, so the problem goes away. Encryption is only defined for digital HD signals.

Sorry, my phrasing was a little unclear; one important word was missing: The DVI _standard_ does not support encryption. The are devices that do, in fact, handle encrypted signals on their DVI ports, but that's not covered by the standard at all. (Unlike the HDMI standard which does support encryption explicitly.)

[ fwiw, i like what i read about the nec 2490/2690; but, i think i'll try a hp 2475 first. being blue on one side and red on the other may not be as bad as it sounds. i might get lucky. compared to amazon, i'll have to see what new_egg wants for shipping. ] > -Warren Block * Rapid City, South Dakota USA i thank all of you for your respective efforts. however, the un_spoken assumption, regarding formatting, comes after use. i would have done the same thing; with use, new ways of thinking become "old_hat". i am pleased to report that i have successfully shifted my paradigm: both were from the philadelphia mint; one 1980, the other 1992. they had been on the left_side of my desk; now, they are on the right_side. the paradigm_shift is to go from thinking in terms of "soft" pixels to thinking in terms of "hard" pixels. an lcd panel has "hard" pixels; the number and arrangement are fixed. in particular, the spacing is fixed. a crt has "soft" pixels; it will display what the input provides [ up to a point; more later ]. with a crt, we think in terms of "filling" the display_area. the pixel size and spacing are variable; 640x480 and 1600x1200 can be exactly the same size. with a lcd, the pixel_density is fixed; the actual size of the display_area will be determined by the pixel arrangement. i start by assuming a one_to_one mapping between "soft" pixels and "hard" pixels. with a crt [ within bounds set by the manufacturer ], i can set the dot_rate and h & v frequencies and sync_positions, permitting me to control the size of the display_area and, independently, "stretching" and/or "squashing" the image in two dimensions, to my heart's content. in particular, the h & v pixel_spacings need not be the same. the display will be sharp, regardless, because the rgb_phosphor_dots are very tiny; where they are struck by electrons, they will glow. there is no interpolation. with a lcd, the pixel_spacing is fixed [ although not required, i suspect that the marketing dept will have an easier time, if the h & v spacings are the same ]. --something-- has to be given to each "hard" pixel, without regard to the arrangement of the "soft" pixels. at this point, let us assume that we have a "high_end", "name" model, lcd_display_device, of "hard" dimension 1920x1200. for simplicity, assume 24_bit [ 8x3 ] color rather than 18_bit [ 6x3 ]. i am going to treat this as a "black box", with a sophisticated embedded_controller running the show. some of these things have half_a_dozen input_connectors, suggesting that the front_end is doing some dsp [ a separate processor ? ] so as to produce, for internal use, a time_sequence, at some rate [ e. g., 60, 75, 85 ], of frames, each of some "soft" dimension, translated to a 24_bit color. i will treat this as a time_sequence of data_structures. the main processor, then, has to decide how to map the pixels, from the "soft" array of the structure to the "hard" array of the installed panel. the easiest approach is one_to_one, centered in the panel [ this --really-- appeals to me ]. other approaches are to fill the panel vertically or horizontally or both. this will, probably, require interpolation; the resulting presentation may or may not be pleasing [ this reminds me of the two approaches to displaying 24_frame film on 30_frame dvd; the "clean" approach is to repeat every fourth frame [ great for single_stepping ], but, some create the fifth frame by mixing together the frames on either side [ this is a big thrill, if the film_frames straddle a scene_change; the effect is as psychedelic as a mid_1960s peter_sellers film ] ]. essentially, one time_sequence of data_structures is replaced by another time_sequence of data_structures. i observe that the high_end models have many options for controlling the presentation of the input. some of these models appear to be true "multisync" models that can handle any legacy_input that is thrown at them [ they all have to handle 640x480x60, with [ count 'em ] 16 colors ] and can format them in a variety of ways. others appear to handle only "standard" or "common" legacy_inputs; i can configure my legacy systems, if necessary. my new intel moboes [ not yet installed ] all have 15_pin analog connectors on them. the "dg41ty" [ but, not the "dg31pr" ] has the 25_pin dual_rate dvi_d connector on it. i think i'll get the hp 2475w, first, just to get some experience with this technology. i suspect that i will, later, get one of those nec models. of course, these choices are not yet final. just for fun, i think i'll implement a dvd_player on one of the machines, just to see what happens. not using any crt, as much, means that their eventual failure_dates will be, somewhat, farther in the future. again, i thank you all for your responses. in particular, i thank you, mr. block, for pointing me in the direction of much information. happy thanksgiving. happy everything. rob From owner-freebsd-chat@FreeBSD.ORG Tue Nov 24 22:45:58 2009 Return-Path: Delivered-To: freebsd-chat@FreeBSD.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 48D49106566B for ; Tue, 24 Nov 2009 22:45:58 +0000 (UTC) (envelope-from "") Received: from mail.wytheville.org (mail.wytheville.org [69.27.89.39]) by mx1.freebsd.org (Postfix) with ESMTP id 172658FC13 for ; Tue, 24 Nov 2009 22:45:53 +0000 (UTC) Received: from (unknown [192.168.70.50]) by webshield.wytheville.org with smtp id 38de_703d_50e45622_d948_11de_ab9c_0014220a3a3a; Tue, 24 Nov 2009 17:25:49 -0500 Received: from ([69.147.83.53]) by mail.wytheville.org (IceWarp 9.4.2) with SMTP id FHF09429 for ; Tue, 24 Nov 2009 17:33:29 -0500 Date: Tue, 24 Nov 2009 17:33:29 -0500 From: Ron Jude To: Message-Id: <997755950@mail.wytheville.org> Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit Cc: Subject: Re: [FreeBSD-Announce] Death announcement for John Birrell X-BeenThere: freebsd-chat@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Non technical items related to the community List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 24 Nov 2009 22:45:58 -0000 Hello, I'm out of the office .

The only advantage a CRT has over a properly calibrated modern LCD panel is "blackness": backlit LCDs can't display truly black pixels, because a little bit of the backlight will still shine through. This is usually not noticeable except when playing certain games or movies in a dark room. I believe there are LCDs with individual lighting for each pixel, but they're probably not within the OP's budget.

You are thinking of OLEDs, which is a different technology. As far as I know, there is not a single OLED-based computer monitor on the market. Smaller full-color, high-resolution OLED screens in numbers are now making their appearance in smartphones, e.g. the Samsung Omnia II. I think the largest OLED screen you can buy is still Sony's XEL-1 bedside television with it's 11-inch display, although at 2500 USD that is more of a technology demonstration. Larger OLED TVs are regularly shown off at trade shows such as IFA, but these are prototypes that aren't in production. -- Christian "naddy" Weisgerber naddy@mips.inka.de From owner-freebsd-chat@FreeBSD.ORG Thu Nov 26 17:31:11 2009 Return-Path: Delivered-To: freebsd-chat@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id C83851065693 for ; Thu, 26 Nov 2009 17:31:11 +0000 (UTC) (envelope-from des@des.no) Received: from tim.des.no (tim.des.no [194.63.250.121]) by mx1.freebsd.org (Postfix) with ESMTP id 87DAC8FC2A for ; Thu, 26 Nov 2009 17:31:11 +0000 (UTC) Received: from ds4.des.no (des.no [84.49.246.2]) by smtp.des.no (Postfix) with ESMTP id 773BD6D41B; Thu, 26 Nov 2009 17:31:10 +0000 (UTC) Received: by ds4.des.no (Postfix, from userid 1001) id 385F4844F2; Thu, 26 Nov 2009 18:31:10 +0100 (CET) From: =?utf-8?Q?Dag-Erling_Sm=C3=B8rgrav?= To: naddy@mips.inka.de (Christian Weisgerber) References: <200911200921.nAK9LKpf063202@lurza.secnetix.de> <4B0AF776.4000802@emailrob.com> <62D9DE9E-1BC3-4B52-90CB-C30107A3FB44@mac.com> <863a423iav.fsf@ds4.des.no> Date: Thu, 26 Nov 2009 18:31:10 +0100 In-Reply-To: (Christian Weisgerber's message of "Thu, 26 Nov 2009 17:20:47 +0000 (UTC)") Message-ID: <863a41ura9.fsf@ds4.des.no> User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/23.0.95 (berkeley-unix) MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Cc: freebsd-chat@freebsd.org Subject: Re: lcd monitor manufacturer recommendation request X-BeenThere: freebsd-chat@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Non technical items related to the community List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 26 Nov 2009 17:31:11 -0000 naddy@mips.inka.de (Christian Weisgerber) writes: > Dag-Erling Sm=C3=B8rgrav wrote: > > I believe there are LCDs with individual lighting for each pixel, > > but they're probably not within the OP's budget. > You are thinking of OLEDs, which is a different technology.

Then you are very confused. LED-backlit LCDs just exchange the light source, from fluorescent lamps to a bunch of LEDs.

It's called local dimming. That's a TV feature where the LEDs are positioned behind the panel and grouped into a number of tiles whose lighting can be controlled independently. I can't find hard figures on the number of tiles, but we're talking dozens, maybe a few hundred--compared to millions of pixels. I'm not aware of a computer monitor using local dimming, but I haven't been paying particular attention to that area. -- Christian "naddy" Weisgerber naddy@mips.inka.de
