There are settings in there to change the gamma, just in case anyone really wants to do that. The navigation on the menus is awkward, use the up down arrows to choose the menu, the channel up/down to choose the submenu, and the side keys to alter a setting. Some of the settings go into a diagnostic mode that you cannot get out of without power cycling the set again.

A lot of those settings aren't labeled at all, so maybe the software developers put in back doors to hack things.

I would advise NOT going into this menu withotu a technician, since I am not sure how to recover the factory defaults if one fo the settings goes awry. It was also not clear if they took immediately, or if the set needed to be restarted, or if they could be tested and reverted or not safely.

Could you let us know what resolution you're connecting at and what you have as your "view mode"? Thanks.

The Sharp is not pure green as it should be. Note the addition of both red (more prominent) and blue pixels. This is not caused by camera blur. Both images are motion-free.

Why are the extra colors there with the 37D90U? I wonder how Sharp will explain this.

New owner of LC 37D 90U after replacing my LC 37G4U. Nice tv although i wish it had side speakers, a little thicker than my previous because of the AVC BOX and so far my DVI and HDMI problems I had with the LC 37G4U are not present. I do have to report a lot of backlight bleed though and I think the viewing angle is as my old tv although they advertise better viewing angles.
Menu settings a little slugish yes but nothing serious.
My laptop is VGA so i connect for now with VGA TO DVI and I can not see the problems you guys are facing.
However, I would appreciate is someone can tell me where I can get those tests you are running so I can see if I have the same problem.
Also for those who have backlight bleed have you come up with something?

Thank you

Jim

However, it should be possible to have different settings for different inputs, allowing HDMI inputs to have different CMS settings than DVI and a third for 480i. But perhaps in a cost cutting measure, Sharp elected not to provide this capability in the 37D90. If it is there, it's within the service menu settings.

I will borrow next week a laptop with dvi and see what I get there.. i am sure i will have the same results. I used a different test. The program is called display mate.

Trying to put the files on here so you guys can see but it says file too big. Any suggestions?

jdr i will run it on that resolution to see if I can get it to display and how it looks.

Also when i connect with component cables the colors on the screen are different from when I connect with DVI or HDMI. They appear to be darker. Not sure if they are more accurate but certainly better than having that washed out look from the digital connections

I use my 360 quite a bit with this set and have noticed a huge difference on this set compared to my old 37D7U which would blur slightly in fast moving games. The 37D90U does not have that problem at all, games look amazing with not a hint of bluring (unless the developers intended to put it in the game) So it is def your DVD player I would think.

As far as the different look using different cables, yes that is normal. HDMI and DVI produce better colors and I noticed are also much better at producing better blacks.

So, please tell me if this TV is: "The best 37" LCD for dual use of TV/Monitor?"

I am gonna hook up my PC to this and use this TV as my main PC monitor, as well as gaming monitor. There are LOTS of reports about color issues with PCs hooked up. ANYONE WITHOUT THOSE ISSUES?

Just wondering if it's the same issue on ALL sets or just on a few of them?!

Thanks a lot!

I have been using this as my main pc monitor for like 2 weeks now.

I too am looking for a dual use HD-TV/monitor (90% monitor, 10% TV). I need to spend a lot of time working in front of this thing, and the problems (particularly the text problems) are a no-starter for me.

Has anyone heard anything from Sharp on this issue?

My other possibility is to go with the Westinghouse W3 and add an HD-TIVO for the TV part of the set.

Any comments?
