Hi *

I have plan to upgrade my TV form CRT to Sharp 46X20.
Do somebody have experience with this LCD TV, GF5200 and driving it to 1080 HD modes ?
If so pls share Xorg.conf.

From NV forums I know there is some issues with proper driving this TV to 1080i.

Also, is it possible to drive it to 1080p ?

What is native matrix resolution in this TV: isn't it 1920x540 ?

Read the user's manual. It will list the resolutions it can accept.


Sharp's LCD panels are either 1366x768 or 1920x1080. The Sharp
web site doesn't know anything about a "46X20" so I can't tell
you which size it is. I've been looking at Sharp and other
brands of LCD TVs for a few months, and I don't think there are
any 1920x540 panels from Sharp or anybody else.

indeed 46X20E has 1920x1080 panel.




Full name is 46x20E. It is upgraded XD1 (thinest frame, XD1 bugs fixed, more light design with lecc components, HDMI1.3 and 24p readiness)

Basic question is inter-work of NvidiaDVI->TV HDMI for 1080p. I saw A LOT of issues with 1080i/p and Nvidia drivers.
As I want to quite quickly and pain-less migrate to this TV - any hints are strongly appreciated.

Your FX5200 may have issues outputting 1080p to the LCD. Some people's FX5200 have no problems and some do. My FX5200 128MB would not reliably output 1080p so I picked up a 6200 128MB for $20 and haven't had an issue since. I connect from the 6200 DVI to my TV's HDMI.

Out of the box the FX5200 driver won't push 1080p but you can force it by putting the following in the Device section of you xorg.conf Then I just use the built in modes and you let it figure out the modeline.

If you want to prevent the TV from scaling and overscanning the
video, you'll want to select "dot-by-dot" mode on the input in
question. At least I think Sharp calls it "dot-by-bot" -- if
not, it's something similar.

Thx for replay !



In Your case 5200 problem was manifesting as instability, bad picture quality or something else ?



What version of NV drivers are You using ?

Modes declared by You in Display subsection are metamodes or taken from EDID or autodetected by driver ?

Thx for replay



Ok, there is such option in TV setup. Good.
I think for achieving it I have fullfill following criteria:
1.drive TV with exact panel resolution (1920x1080 here)
2.turn-off in TV all "picture correctors" like DNR, etc.




Right. This model has dot-by-dot option. Is it reasonable to assume that this TV has phy panel resolution exactly of 1920x1080 and when we choose dot-by-dot option - it will act exactly as computer monitor (map exactly input pixel to triade on panel) ?

The picture was great but I would have flashes where the screen would go completely black. The flashes would happen about every 7-10 seconds and would last for about a half a second. It was rock solid at 1280x720 but anytime I would kick up to 1920x1080 I would get the flashes back.


I am using what R5F27 installed which I believe is 9755.


The modes are from the NVIDIA Drive ModePool.

That's my understanding based on reading the Sharp user's
manuals and a couple threads in the AVS forums.
