Anyone got 1366x768 1:1 on Sharp LC37GD7E or LC32GD7E yet?

I want to buy a Sharp LC37GD7E, but need to know beforehand that it supports 1366 x 768 "dot for dot" - I've emailed sharp.co.uk and they say it will, but the German manual (UK one not available to download yet) doesn't actually indicate what resolutions are supported.

I don't want to spend £1900 to find out Sharp support weren't right, I'd like some actual proof from someone in the real world!

I'll be using an Nvidia 6600GT which I know can output 1366 x 768, and if anyone has the advanced settings (Front porch, back porch, sync polarity, & sync width) that are needed to set up the custom resolution for the GD7E's that'd be much appreciated!

Oh, I'll be connecting to the 15-pin VGA port (not HDMI) on the LCD.

Same choice of TV, same question, but I would specifically like to know what resolutions (1360x768, 1366x768, 1368x768) people can get at 1:1 mapping over the HDMI/DVI connection rather than the VGA.

PC res info on any of the analogue sets in this range would be equally useful. Thanks in advance.

If it has a VGA port, then it will almost certainly support 1:1 pixel mapping - it will either use 1360x768, 1368x768 or both for it. PC video cards are not capable of 1366x768, as they must render a multiple of 8.

The Samsung LE32R41B (which I am considering replacing with the LC26GD7E) will take 1360x768 and have 3px either side, or 1368x768 and cut off 1px either side. I would imagine this to be the same.

The manual I saw didn't look like the set had VGA though? I just saw DVI-I and HDMI. (as well as SCART, Component etc)

That's a very dangerous statement to make. Just because it has a VGA port doesn't mean it supports any resolution you'd hope they support.

I didn't say that it would, just that it's very likely. I've not seen an LCD (other than the really cheap things Supermarkets are selling) that has a VGA port and doesn't support native res. It would be stupid for Sharp to have VGA and not have it.

Complete Toshiba 56 series doesn't support native resolution over VGA, many other example could well be posted. Using Powerstrip some user get a underscaned image to look like full screen.

My "supermarket special" allows [email protected] and [email protected] and [email protected], over VGA but then scales them to fit the screen :suicide: . I am sure it is not alone in having this "feature".

Thanks for the replies. I'm well aware of all the ifs, but's, maybe's, should's, etc regarding PC resolutions as I've been looking at LCD TVs for almost a year.

What I'm hoping to get is cold hard facts about whether native resolution over digital does or does not work with these Sharp TV's.

I second that - just waiting for a decent 37" with native res over a digital input, for HTPC use.

Another thing to make sure of is that if you don't use a PC that outputs only DVI-PC (0..255) levels with a display that expects only DVI-Video (16..235) levels otherwise you will have problems calibrating the combination if indeed it is possible at all. This scenario is quite likely with a TV panel that supports HDMI input only when used with a PC but thankfully it can be calibrated out only with a loss of dynamic range - the other scenario, DVI-video levels into a DVI-PC monitor results in clipping of the dynamic range at black 0..15 and white 236..255 resulting in grey blacks and off white whites which is mostly impossible to cure.

My graphics card ATI X800xl has a component break out box (hdtv) would this make any difference?
I was thinking of setting up my PC with dual monitors - the primary being the 19" TFT ive got and the second being the 37" or 42" TV in the lounge (currently the 42wlt58 if it actually ever gets delivered.)

Would this work?

Haven't managed 1360x768 1:1 with a 6600GT over either VGA or DVI yet, even though the guy at Aquos support says he has with a ATI card.

Some (random) comments:

*you'll never get 1366 with an nVidia or ATI card: res has to be a multiple of 8, but if you could get 1368 to work that'd be fine: just lose one pixel each side. Even if it says it's doing 1366 in the driver, it'll still be really 1368 or 1360. I got 1360*[email protected] to work, but it wasn't quite right (not sharp, huhuh, hey that's funny) and if you went to a tv and then back it didn't want to sync again.

*powerstrip parameters (front porch,...) and nVidia control panel parameters with the same name do not give the same result. (a matter of definition, of course, but just so you know)

*it should be possible in principle to get it working at 1368, though finding the exact parameters is not trivial. I have tried hard, believe me.

*if you use the moninfo program over dvi it'll give you all the "factory supported" resolutions. 136x*768 isn't among them, but again, that doesn't mean anything.

*1280*720 @ 60Hz works fine over both dvi and vga, but of course it's scaled, not 1:1. For games or movies this is just fine. HL2 looks a-ma-zing. I just switch to standard XGA if I want to do web surfing. In the end it's not such a disaster. And it is 1:1 and razor sharp both over vga and dvi (though not that sharpness may depend on your card DAC and your cable).

Hope that helps. If we all keep asking the Aquos support people, maybe they'll contact the designers of the circuits in Japan and sort it out once and for all. They're quite helpful.

I found this on tinternet where someone got 1366 x 768 on an older Aquos - might be worth a try:

Good luck and keep trying (please!) preferably on VGA instead of HDMI...

Implementation
1. Open the nVIDIA Screen resolutions and refresh rates fly out tab in the nVIDIA ForceWare drivers
2. Uncheck Hide Modes that this monitor cannot support and click Apply
3. Go to Digital Flat Panel Settings and select Display adapter scaling and click Apply
4. Start Power Strip
5. From the task bar, right click on the icon and select Display Profiles->Configure...
6. Click on the Advanced timing options... button
7. Click on the Custom resolutions... button
8. Create a new custom resolution with the following timings:

Horizontal Geometry
Active - 1366 pixels
Refresh rate - 49Hz
Front porch - 38 pixels
Sync width - 184 pixels
Back porch - 220 pixels
Polarity: Negative

Vertical Geometry
Active - 768 pixels
Refresh rate - 61Hz
Front porch - 3 lines
Sync width - 6 lines
Back porch - 29 lines
Polarity: Negative

9. Click on the Add new resolution button
10. Click OK to try the new resolution
11. Click Yes to keep those settings and return to advanced timing options
12. Change the Vertical geometry Refresh Rate to 60.216Hz. and click Apply, then OK
13. Click OK and close Power Strip

If the above steps worked for you then you have a working desktop resolution of 1366x768. If not then try the same steps again or perhaps the drivers still have some bugs to be worked out—if all else fails try newer drivers and see if that works. Once you have your working desktop resolution you aren’t out of the thicket yet! You now need to create a custom monitor driver in order to unlock your new custom resolution for screen savers and video games.

Power Strip has its own built in monitor driver wizard (see Monitor Information in Power Strip). Alternatively you can use my own custom Sharp G4U LCD driver. Remember to disable WHQL support because my driver is not certified and you will have to acknowledge that fact in order to install it. Simply change your driver from the Microsoft default of Standard Plug ‘N Play monitor to your own custom driver and you are done. You may need to reboot your PC in order to see the new resolution in screen savers and video games.

If you would still like to try to craft your own EDID to fix resolution problems as well as other issues then you have two methods to choose from.

if only retialers would alow us to lug our pcs to the show room and try it. would make buying an lcd much better for most of us

A decent one will allow you to do this. I did exactly this with my HDMI DVD player a year or so ago when most people, including shop staff had never heard of HDMI. It is curtious though to check with the shop first and pick a quiet time. I would always recommend doing this when wanting to pair up a source and display using HDMI/DVI as there are so many things that may not work or perform as you would like. I ruled out the Sharp GD1E because its EDID was incorrect and would not support native at 50Hz and the Philips becuase it had borders at 720p. These are the sorts of things that you do not pay much attention to until you actually try a combination.

I don't know about 1:1 yet, but the speaker is no longer detachable. The stand is now fixed too; you can't rotate/tilt it like you could with the GD1E. It seems that Sharp have been working on bringing the cost down for these models without lowering image quality. (and at £1200 less than the GD1E it must be working)

Hello everybody.

I worked very hard this weekend with several sessions of tries,
first by an nv geforce 6150 integrated on my Asus A8NVM-CSM and then with one ATI x1650 pro pcix .

I used the latest version of Powerstrip following the EnTech forums and several combinations found elsewhere over the Internet for panels that would have to be equivalents to mine (for ex. Sharp 32ga5).

I use a 5 mt DVI cable (gold series) by Lindy (http://www.lindy.com/it/productfolder/04/41242/index.php) .

Results:
1 - Geforce 6150 + powerstrip (several config.)

The vga effectively sends 1360 or 1368 horizontal pixel, it seems without problems ( no disturbs or distorsion, the font and the rest of desktop are very clear and sharpen ) but the panel always get one res. of 1280x768 although many tries of auto sync and fine sync via sharp menu by remote control.

Therefore I have two black sidebands and moving the mouse over the desktop it slides to right and on the left (virtual desktop style ) in order to visualize the lacking portions of the screen!

2 - ATI x1650 pro
The driver supports natively 1360x768 and 1368x768, but for both the risolutions the panel marks them as 1280x1024 (that standard VESA res. effectively supported according the datasheet into the Sharp handbook).

I have tried many customizations of the parameters by powerstrip, but every time the ATI goes to 1360 or 1368, the pan. sets itself @1280.

I ask to myself if effectively is there any way to set up 136... x768 res. (not VESA standard) by DVI connection .

But why then it works @1280X768?

Can it be a cable problem?

Thanks in advance
Tarcisio
