  DVI-D is digital interface & D-sub is analog...
  In Dsub digital data is converted to analog transfered over the cable..
  Dvi-d directly transfers digital data & is much superior..
  dvi & hdmi are electrically same .only difference that dvi cannot transmit audio ..

  Then why we don't see any difference in the output ? I can't find single improvement in visual when I switched from D-sub to DVI-D. Why ? 😨

  As #-Link-Snipped-# said, the D-Sub is the analog one and DVI-D is the digital one. In my opinion all the digital connections would more or less look the same quality but with VGA (D-Sub) you should see some different. I see that on the TV the digital connection offers a noticeable improvement in the overall picture quality.
  
  I didn't play with the cables much; but curious to know if changing the resolution makes any difference?
  
  Also, check if you can play the games with full resolution supported by your monitor.

  Okay, I reconnected D-sub with D-sub port of Monitor and checked the clearity;
  & then connected DVI with DVI port of monitor, tested it.
  There is no change, I re-assure you.
  
  Can anyone test it on their gadgets ? I honestly see no change 😲

  Analog signals are more affected by noise. Right? If that is right, D-Sub can suffer from more interference.

  Yes, but it is not. Any reason behind that ?
  BTW within 2 days I will buy D-sub to DVI adaptor & will report the result here, I am sure there won't be any loss in display quality even if I use adaptor.

  As long as you use quality cables for analog transmission (D-sub), you can't notice the difference between the two.

  Please help in this too : HDTV & PC Monitor Simultaneous Connection Query.
  I am dying to connect two monitors together if possible. No replies since morning on that thread 😖

  Difference gets obvious when cable length is more ..
  d sub will suffer from color distortion@ higher resolution..
  my graphics card detects dvi d as hdcp compliant.

  RCA can cause blurs, but D-sub ? I don't think so!
  However I connected D-sub to DVI converter, it cost me around 75 bucks. Tested it with DVI-D port. Nothing appears on screen 😡
  Now, what could be the reason ? 😕

  #-Link-Snipped-#, what comparison tests are you doing? Displaying the desktop or playing games?

  Right now, just displaying desktops : But I wanna know the real difference between DVI-D & D-sub. Here CEans are saying that you see blurs in image in D-sub & DVI-D will be crystal clear.
  Honestly, I see no change in both. So, if there's no change then what's use of DVI-D ?

  DVI (and HDMI) is more useful if you are playing hi res gaming & HD/bluray videos where digital signalling trumps over analog (in terms of quality degrading loss). Other than that, D-sub is sufficient.

  #-Link-Snipped-# So as I am not playing games in pure HD i.e 1920 x 1080, it doesn't matter whether I choose D-sub or DVI-D, right ?
  I tried both port & played for few minutes in TF2 & I noticed no change in display quality. Maybe because I am using 1366x768 (native 720p) ?

  Okay, I found the solution :
  In D-sub to DVI converter. DVI was analog one i.e. DVI-A, there are two DVI pins DVI-D (digital) & DVI-A (Analog). I read in few forums that D-sub to DVI-D is not possible. (it is possible but the adapter costs around 35$ so not worth it )
