Christmas Wish list (I): Monitors

Posted on 07:39 by Unknown
Hi,
Christmas is here and for people lucky enough this hard times to be able to buy some reward for them you have
Monitors :
LCD of course for size,weight,etc..
Well monitors we have some factors but knowing that 24inch fullhd cost 200eur we want to spending some more have more features..
this factors:
the "classic" factors:
1.size
2.resolution
3.color depth
the new factors:
4.touch
5.3d stereo..
Also speakers,Webcam,microphone,etc..

Regarding size 24" cheap 26-27" next thing..
Until now 27" are fullhd only (1920x1200) with the exception of news Imacs 27 that seem not to arrive still..
If you prime size and cheap you can get a say 30-32 FullHD LCD TV and you get low prices good color and response time (2ms..) and also TDT (in Spain at least..)..
say 300 Eur.

We go to resolution 1920x1200 standard (200eur or less) now hot stuff at 4m pixels.. said if you avoid 3D LCD monitor (as Nvidia 3d vision samsung 22) you get fullhd.. for some years you have 30 inches with 4mpixels..
and now with Imac 27" also near 4mpixls (2560*1440).. now PCs get via Dell UltraSharp U2711 also this panel:
http://vr-zone.com/articles/dell-ultrasharp-u2711-release-soon-/8173.html
Hopefully less than 600eur.

This is the more balanced if you want high resolution.. you don't need to spend a fortune like for 30inch 4mpxiels or not and Imac and hopefully 50%-75% of that..

8bits per channel since ever (some stereo monitors 6bits)->10bits here->12 bit coming?
HDMI 1.3 adds 10 and 12 bits per chanel is named DeepColor but as 30bits is more easy as to pack with current 32bits per color (using no alpha or restricting to 2 bits).. there are also hardware supported as framebuffers (FBOs) and texture samplers of GPU as shows OpenGL..
Supposedly also H.264 also supports it (some advanced profile)..
also Bluray adds this profile as optional(?) so Bluray players should we use it..
We would need a Bluray DeepColor player a Bluray deepcolor movie and HDMI 1.3 cable and a monitor with 10bit panel to support it..
Some Bluray coded with 10bit per channel color or video sample in Internet?

More than 8 bit requires more than a monitor supporting it in computers..
*Graphics cards (artificially limited to Quadros and FireGL..)
*cable (HDMI 1.3? (DeepColor),DVI(with hacks),Displayport).. see Nvision08 presentation..
*SO (Linux and WinXP some limitations, Win Vista/7 good) (mac?)
*in OpenGL create context with these bits
(you program needs use perhap HDR textures.. etc.. to use full depth)..
*SceniX supports it..

So to avoid problems you need it a Quadro/Radeon with HDMI 1.3 or Displayport and Windows Vista/7 or Linux..

For Nvidia use see Nvision08 presentation..
HD is now 8MP & HDR
http://developer.nvidia.com/object/nvision08-hd8mp.html
for AMD see..
http://developer.amd.com/GPU/WGSDK/Pages/default.aspx
AMD’s 10-bit Video Output Technology
http://developer.amd.com/gpu_assets/10-Bit.pdf
http://developer.amd.com/Downloads/10bit_demo.zip
for OpenGL textures and FBOs see..

Well monitor I know only one "affordable" 24 inch FullHD..
HP DreamColor LP2480zx Professional Display.. (600 eur more or less)
about Dell UltraSharpTM U2410?
says panel supports 1billion color and uses internal processing of color 12bits..
but can you drive 10bits (panel 10 bit really?) via HDMI 1.3? I don't know..
Also a lot of TV LCD monitors say 10bit color panel or Deepcolor panel and HDMI 1.3 (is that really)? they seem to offer FullhD and big sizes relatively cheap..

Touch
Well I want also at least fullhd (some less than 24)..
With Windows 7 launched there is a lot of monitors but a lot 22 or less of size..
DellTM SX2210T 21.5"W Multi-Touch (fullhd) 2mp camera
Ilyama releases multi-touch 22" monitor T2250MTS (fullhd)
Elo TouchSystems 2420L 24" Touch Screen LCD Monitor

also
desktops:
Dell's multi-touch Studio One 19 PC
notebooks:
Dell Studio 17

Also neetbooks include it..
APIs: Windows 7 Touch API (Windows SDK and code samples in MSDN)..
Linux Freeglut enabled MPX(?)
Apple ships private framework for Snow Leopard (touch api?) for mighty mouse..


Linux can have all.. 10 bits is supported in OpenGL (and distro?) with code samples in quadro cards and 10bit monitor.. 3d vision is supported since 195.22 with Quadro cards.. and touch you have MPX patch for Freeglut and using X server 1.7, there are drivers for touch panels.. and Qt 4.6 APIS and Linux?..

Seeing mac we have good size 27, 4mpixels and quadros so I don't know but theoretically you have all needed for 10bit color.. you lost for sure touch and 3d..
Touch is in private api at leat since 10.6.2 with mighty mouse.. so seems we need a Cocoa Touch for desktops and driver for touch drivers and we can have multitouch in mac.. Regarding 3d we could have support for passive displays as Iz3d as isn't a usb device and don't need to configure for special hz. Only need to know the algorithm as Iz3d what to send to each DVI port.. Luckily there is open soure Iz3d media player so you can see how to use that..
For 3D Vision and active displays we would need a driver that enables OpenGL QB with 3d Vision cards..
