The answer is, Yes, a CRT is capable of reproducing a HD picture. In fact there are a few manufacturers who are currently producing 16X9 HD TV sets which use a CRT as the viewing device. Samsung would be a good example.

As to whether your old CRT TV will, is another question. Probably not!

Not a dumb question, really. The majority of displays available when HD got started were CRTs. The issue has to do with increasing the operating frequencies so that more lines can be drawn by the TV. As you note, your TV doesn't have any possibility of doing that. On the other hand, a customer from several years ago has a Sony G90 projector with a Faroudja line quadrupler that displays an incredibly film-like image, even when the Faroudja is being fed garden variety video. That has to do with the quadrupler figuring out what the likely pixels would be in between the bits of information that the regular video has, and then sending that signal to the display with a horizontal frequency, for instance, of something like 60 kHz instead of the older 15,750 Hz.
A good answer is easier with a clear question giving the make and model of everything.

As long as your HDTV receiver has an S-video or Composite video output you can hook it up to your old crt tv and watch downconverted HD content. If your tv doesn't have an S-video or Composite video input it can still be done. You can either connect the RCA Audio/Video cable from the HDTV receiver's Composite output to the Line In Composite connections on a VCR that is connected to the tv or to a RF Modulator that is then connected to the tv. Some RF Modulators even have an S-Video input such as the Dynex RF Modulator ($29.99 at Futureshop).

I believe the desire is to observe HD content in HD quality, which the above will not accomplish.

Larry, if you read his initial post, he simply asked if a crt could display HD content and in what way. I'm sure there are a lot of people out there that think they have to run out and buy a new HDTV when in fact their existing one will still work.

OTA,
he clearly asked if a CRT could display HD content in the context of that ten year old TV in the basement, not just in general. My answer told him that yes, A CRT, SOME CRT, can do this, but yours can't.

It is just not right to call HD video downconverted to NTSC "HD content." Would you call Dolby Digital 5.1 mixed down to monaural "5.1 content?" (The fact that 2-channel and even monaural Dolby Digital exists is irrelevant here; we are talking about 5.1 being converted to mono.)

Perhaps when we are so used to HD that we all understand the differences between different resolutions, and this is second nature to all of us, we will be able to tell him that his TV, by then some twenty years old, can display "HD content," because by then, we won't be so focused on the format being part of the content itself.

Calling what would end up being shown on an old TV "HD content" is akin to watching a The Sound Of Music on VHS and calling it "70mm film content". :-)

A quality HD downconversion will basically show whatever display device at its absolute best reproduction capabilities... but it won't be anything close to HD.

That's exactly the point I have been trying to get across. Rather than just telling someone that their old non HDTV tv set won't work with an HDTV receiver you should give them all the facts. They may be happy with just being able to watch the HD channels for free over the air even if the picture is downconverted and not in true HD. Let's face it, not everyone has the money to buy a new HDTV tv and some could care less if the picture is in true HD or not as long as long as they can still watch their favourite programs.

this is a good point

I have 2 OTA atsc recievers, one hooked up to an HD display, one hooked up to a vanilla 8yr old 20" Trinitron TV in the bedroom.

Reason ? I dont have cable or satellite. the atsc reciever delivers a solid good quality ntsc signal on my second bedroom set. True - it's not HD, not even close, but it's better than a ghosting and/or snowy analog signal. I think a good comparison is: its similar to a DVD picture on a regular TV.

Eventually I'd like to replace it with an HD model, but I'm one of those people who doesnt have the money right now, and am somewhat happy to settle for a decent NTSC picture for now.

Hi guys,,just a follow up to my original post..thanks for all the responses..i did purchase a new LCD..an olevia LT 30HVS.from a authorized dealer online and just finished hooking up everything..Samsung prog. scan dvd..jvc hd-vcr..motorola dct6200..and yamaha htr 5640..the tv has Y/CB/CR and Y/PB/PR component inputs..its supposed to support 1080i/720p/and both 480 signals..first thing i noticed is the DVD would only play thru the P component..due to it being progressive scan i guess..no problem there..but when i tried to display the hd cable and hd-vcr the only way i could get a picture was when they were both set to 480i output..if i tried any other output the screen would remain blank..am i missing something?..both of those pieces are input thru the Y/CB/CR input..the picture is good..but honestly my ED Panny displays HD better..just wondering if im not setting up something right or if...im hoping no...the set is defective in some way..any opinions or advice would be great...Thanks!..do i have to use the DVI connection to get 1080i?

If there are multiple component inputs check that the one you're hooking up to supports HDTV. You mention the "P component" as if there are more - chances are the "P" one is for HDTV (480p/720p/1080i).

If you have a standard DVD player it should work through the normal component input (assuming there is one that only takes 480i signals). If it's progressive scan, try turning that feature off (you may not need it).

DVI/HDCP would be the highest quality way to get HD to your set.

Thanks Daniel..what i meant ..tring to simplify things..was that the set has 2 component inputs..one is y/pb/pr..the other y/cb/cr..i assumed there was no difference..but now after your advice ive switched the 2 and i can now input 1080i no problem..the picture is noticeably better..only change i do not like is all SD channels are in 4:3 ..i assume thats the set ..the aspect is set for 16:9 ..as far as the Dvd goes ill try turning off the Prog. scan feature and input that thru the y/cb/cr..its amazing..i have 4 LCD..3 Different brands..1 Plasma..and each one is different in one way or the other..now i see why some of the guys on here are a bit testy sometimes!..lol...just reset the Hd stb and now the aspect is correct..by the way Daniel..this is the BEST dang website..but i do wonder what ever happened to Hoss10..remember him?
