Aligon, A DVI-D (the D standing for digital) transmitter will not drive a VGA input. DVI-D is pure digital - no analog signals. VGA is a pure analog connection. Never the twain shall meet -sorry. DVI-I connections contains both the digital and analog signals therefor you will find hybrid...

It is due to the compression, not your reception. When your reception is poor you will get the following types of visual effects: 1) Occasional large block sections that contain video that is completely different than what should be on screen. This is due to multipath problems. These blocks...

So far, Texas Instruments (the makers of DLP) have not made a 1920x1080 DLP chip for the consumer market. They do have a 2048x1080 chip that is used in projectors for Digital Cinemas. If you want to see what one of these projectors looks like check out...

Quick point of fact. The video signal stays digital in a DLP set. Your eyes do the analog conversion. The micro mirrors are flicked back and forth in a digital fashion and the persistance of vision effect of the eye takes the high frequency flickering and smooths it out. But I'll admit that...

Monster Cable is a pure exercise in marketing and propaganda. Their least expensive DVI cable runs around $90. I have done testing using DVI cables and have had flawless results all the way to UXGA resolution (the highest data rate I could send) with a DVI cable I bought for $17. Also, this...

If you study information theory, Shannon's theory will tell you that DBS can not get to the point that cable can in terms of Mbps per MHz of bandwidth. This has to do with signal-to-noise ratio. This does not mean that DBS can't compete with cable. They do have some room to improve both...

Chevy, I just switched to the Radio Shack model you just mentioned from a Terk TV-55 that I spent 100 bucks on. The radio shack is doing a better job for me. All of my towers are within 8 degrees from each other (compass direction) so a directional Yagi uda antenna does better for me than an...

Yep, those old style RPTVs use cathode ray tubes to create an image so RPTV has four possiblilities: 1) CRT based 2) LCD based 3) DLP based 4) LCOS based

Oops, I was wrong, 108MHz is enough for HDTV but not for oversampling. Once Blu-ray comes out we will see more video DACs at 216MHz and above for HDTV. Still it doesn't look like the Sony upconverts the component output.

It does not look like the component video on the Sony model you are looking at will output an up-converted 1080i signal, just the HDMI connector. If you look at the video DACs they are 108MHz which is not high enough for 720p or 1080i, but nevertheless are excellent for 480p. Oh, yeah and...

Both satellite and OTA compress the signal but the OTA guys would be less likely than SAT providers to compress the signals into mush. The SAT providers want to maximize profits by offering as many channels as possible over their bandwidth. The locals don't want their signal to look ugly...

Zubinh, The DVI interconnect was created to provide a pure digital connection between a computer and an LCD monitor. In this way a conversion to and from analog can be avoided and the signal degradation in doing so is removed. The reason this connection is being pushed into the home...

Hi, it looks like there is some confusion about the upcoming HDTV optical disc players. I will try to help clear some of this up. There are existing DVD players that upconvert the DVD video to 720p or 1080i. This is not true HDTV since it is merely an upconversion (although it can look quite...

ShimmyShimmy, It is not an issue with the DVI-I and DVI-D. DVI-I contains wired connections to both the digital and analog video signals(R, G, B, Hsync, Vsync). DVI-D is digital only. Your set is only receiving the digital signal. The issue is with the video driver in the computer. You...

Room for Voom I certainly hope Voom makes it. To me, Dish and DirecTV barely are differentiated from each other but Voom is clearly trying to do something different. I just hope that the people at Voom realize that their customers are probably going to be a bit more focused on PQ because the...
