SHARP, DVI to HDMI loss of quality Can't Post

Hello!! This is my first post on this forum. As the topic suggests, this is a question related to DVI to HDMI.

I just bought a new SHARP 32Ē HDTV Ė exact model number is LC32SH2OU Ė and it my first HDTV ever, so my knowledge is very limited. My first question, is SHARP a good brand? I was speaking with a sales rep. at Best Buy for a while, and he told me that SHARP and some other brand, I think it was Toshiba or something, were the only two companies that actually manufacture the HDTV panels. All other companies buy their panels from these two. Is this true? Also, if anyone knows, is my actual HDTV any good? Iíve heard some complaints about a crappy contrast ratio, but Iím not all too sure if that even matters to me. Hereís a link to it on the FutureShop website, it wasnít on BestBuy's anymore: http://www.futureshop.ca/...S10073953&catid=

My second question is with regards to a DVI to HDMI connection. I currently have the TV hooked up to my PC using an DVI to HDMI cable. When I first did this, the resolution was at 1280 x720, and it looked great. But Iím a fiend for high resolution, and when I saw I could get up to 1920 x 1080, I did it right away. But as soon as I did this, there was a huge difference in the image. Now, any window I view on the HDTV flickers, as well as any text on the screen. It looks similar to that of a CRT when it is operating at a low frequency. Currently, the HDTV shows up a generic default plug and play monitor, and is operating only at 60Hz :( thatís horrible I think. Is there any way to fix this problem? My video card is a NVidia GeForce 6600GT if that helps any.

Well, Iíll leave up to you guys, thanks for any information or help you can give me.

If it was so good " Why did Best Buy stop carrying it " is a question I would ask myself.



That set will not output 1080p, so it has downconvert it to 720p 0r 1080 i ( p = is progressive and i= is interlaced ) So when you sent it the 720p source it accepted it without any further conversion, so it looked the best.


You need a 1080p set for the 1080p feed to be used without any conversion by the set.


So if you go back to the to 1280 X 720 feed you are geting the best performance out of that tv.


DVI only carries the video signal and HDMI carries both video and audio signals.


As contrast ratio-the higher the better.
Definition: Contrast ratio is the difference between the brightest whites and the blackest blacks that a TV or video projector can display. High contrast ratios deliver whiter whites and blacker blacks and a greater degree of gray values in between. If the contrast ratio is low, even if the image is bright, your image will look washed out. Contrast ratios of at least 1,500:1 are good, but 2,000:1 or higher is considered excellent.


This set is 1200:1

This one is 1600:1

Yea it's wierd because it WAS on their website yesterday. I had posted my question at around 3AM in the morning today, and it was no longer there.

So basically, my HDTV is a piece of shit? Haha.
I just put a black to white gradient on my HDTV and I can see exactly what you mean - there is a lot of banding between black to white.

My price range is no more than $1500 CDN including taxes. so which is around $1300 before taxes. That'll be around $1100 USD. Can I get a 1080p HDTV for around that price?

 Basically, what you bought is Sharps low end LCD unit. this is NOT an Aquos set which is their premiere line. These units are currently not serviceable by anyone other than Sharp right now vs. their Aquos line which is.

A piece of shit? Well, there are basically 2 levels of LCD TV's on the market today. The upper end with decent contrast ratio and low refresh rates along with a decent picture on non-HD pictures and then there's what you and just about everyone else is buying. I wouldn't call it a POS but you certainly can't expect BMW performance if you're going to spend Chevy prices.

I guess so, that sucks. A Chevy Cobalt ain't that bad though compared to a BMW 3-series lol =)

Are there even any 32" HDTVs that have 1080p? I've looked at the most expensive in that BestBuy has and they're all 1080i.

I think the smallest set with 1080p is 50".
If you can exchange your set, this Sharp is Aquos for only $1169.99

Alright, well I shouldn't feel too bad. There's no way in hell I could afford a 50" at this moment, and no way in hell would it fit in my small room.

Yea, I can definitely exchange it, I got 30 days. :D
So what's the difference between mine and the AQUOS? Better contrast ratio? I checked the SHARP website and apparenlty mine has AQUOS LCD

Also, my HDTV wasn't actually taken off the website, I just couldn't find it because I bought it for $999CDN, and that was what I was looking for. It actually went up to $1399CDN http://www.sharp.ca/...sp?cat=78&id=631

johnny - If you are happy with your set, that is really all that matters. If you want a set with higher contrast- there several options that may be in your price range ?

That last link was a Sharp with 1200:1 contrast if you want a higher contrast set.

Good Luck
