Need info on BASE VIDEO System Configuration, Windows 7 System

[Pettyofficer]

Finally got PC VGA to work with VGA Input on Sharp LCD TV LC-

42SB48UT. Currently using Windows 7 Home Premium 64Bit System.

Had to utilize BASE VIDEO App. in Start-up System Configuration. Any attempt to change from BASE VIDEO, and VGA

signal is lost to "Not Supported". BASE VIDEO Mode is bare

minimum Video Driver required for Start-up. BASE VIDEO automatically defaults to lowest Resolution Setting upon every

start-up, no matter how many times you adjust Resolution. Searched AMD, ATI RADEON, SHARP, and MICROSOFT for Video Driver

compatible with LC-42SB48UT. SHARP has no Software/Drivers available for LC-42SB48UT, AMD-ATI-MICROSOFT are non-specific.

Tried AMD most recent Catalyst, no effect. Ran Windows 7 Video Driver update, Windows 7 claims most recent Driver installed,

still same problem. Tried E-mail to every Corporation, get

nothing; but, run around. Can't believe that there is no

Compatibility Video Driver available for LC-42SB48UT, for

normal Adjustment of Resolution (setting remains the same upon every Start-up). Lowest Resolution matches SHARP Manual

Setting, but images are grossly huge, and distorted. Adjustment required upon every Start-up. Anyone have similar

problem with SHARP LCD TV LC-42SB48UT? Anyone ever found Normal Video Driver compatible with LC-42SB48UT? Is there an

alternate solution for maintaining Adjust Resolution Settings with BASE VIDEO? Did SHARP just drop the ball with the VGA PC Input to this Model LCD TV? It doesn't seem like PC Input ready without the proper Software or applicable Video Drivers. Could still try super long HDMI (expensive), but did buy a SHARP Product that promised that its VGA Input would work. Atleast follow-up with some Video Driver Software, or something, someone, anyone! Would appreciate any info. anyone could provide.

Look in your Sharp manual and see if you can find out what VGA resolutions that TV supports... You'll be looking for something like "1024 x 768 16bpp" (bpp = Bits per pixel) ...

 

Now open your Control Panel -> Display -> Adjust resolution

 

and select one that matches your TV set.

 

Also, are you running single monitor through the TV or is the TV your second monitor?

 

 

 

EDIT... I just went looking... It's on page 42 of your manual.

 

From the VGA port... 720 x 400, 640 x 480, 800 x 600,1024 x 768, 1280 x 768*, 1280 x 1024, 1360 x 768*

 

From the HDMI port... 640 x 480, 800 x 600, 1024 x 768, 1280 x 768*, 1920 x 1080*, 1280 x 720*

 

All are at 60hz vertical refresh.

Thanks CommonTater. I can adjust Resolution to match SHARP

LC-42SB48UT Settings in Manual, but ONLY in BASE VIDEO Mode.

Alter from BASE VIDEO, and image becomes "Not Supported" no

matter what Adjust Resolution is set. I have tried them all in

the SHARP Manual. Can ONLY Adjust Resolution in BASE VIDEO

Mode. Have only one VGA Output on PC, for one Monitor at a

time. Extreme length of HDMI Cable is highly expensive. Bought

SHARP LCD TV as advertized with VGA Input available, was I

lied to? Where is the Software to run Normal VGA Input to

SHARP without having to reset Adjust Resolution, over and over,

on every Start-up with BASE VIDEO? BASE VIDEO is not a

requirement for any other PC Monitor that I am aware of. Why

is this Monitor different? Why does Windows 7 ONLY recognize

this particular Monitor as a "Generic Non-PnP Monitor"?

Where is the COMPATABILITY Software? Why design a product

with a VGA Input, implying compatibility, when it is NOT

compatible with a NORMAL Video Driver? BASE VIDEO is not a

Normal Video Driver utilizing memory for last Adjust

Resolution Setting. Why isn't there a warning that SHARP

Monitor VGA Input will not work with NORMAL VIDEO DRIVER, but

only with extreme limited BASE VIDEO, eliminating most

benefits of all VIDEO DRIVERS available for all other PC

Monitors? Who dropped the ball with this particular SHARP

so-called VGA Input, Microsoft? If they are going to advertize

VGA Input, shouldn't they also include the Software for a

fully functioning VGA Input, instead of a crippled one? This

just isn't a fully functioning VGA Input, and no-one intends

to create the Software needed to make it so!

Does anyone have a solution for maintaining Adjust

Resolution Settings in BASE VIDEO Mode? Does anyone have

Compatibility Software/Video Drivers so that SHARP VGA Input

behaves the same as all other VGA Inputs? Where is the VGA

Standard for this thing, and why isn't anyone warned that

SHARP VGA Input doesn't meet this Standard?

 

[CommonTater]

First of all, lots and lots of people have their PCs connected to their television sets... It's called a Home Theatre PC or HTPC... It's entirely doable.

 

No a television set is not going to give you plug and play compatibility. Windows will see it as a "Generic Non-PNP Monitor" but that should not matter.

 

Boot your system into a normal PC monitor... now set the resolution of your video card to match one in the TV using the directions I gave you earlier.

 

Please note: Not all cards will support all monitor modes... not all TVs will support all card modes... find one that matches between the two.

 

For example try 800x600 60hz at 24bit color... this is easy to set in control panel. It will be stretched horizontally or may not fill the screen because 800x600 is not a wide screen mode, but try it anyway...

 

Unplug the VGA cable from the monitor and plug it into the TV set... does it work?

 

If not, then my only remaining suggestion is that you're going to have to get a technician to come in and set it up for you.

Commentator-already 50 steps ahead of your suggestions. Ancient

History. Tried every compatible Resolution setting in SHARP

Manual via ACER Monitor/PC, before plugging in to SHARP LCD TV.

Not Supported, is only video feed from 18 SHARP Manual

Resolution Settings. VGA Connector is almost worn out, 36 times connect and disconnect. Nothing worked. Last step was

BASE VIDEO, which was ONLY thing that did work with SHARP. Any

variation from BASE VIDEO, Video is-Not Supported-again.

Severely limited to BASE VIDEO ONLY, nothing else will work with SHARP LCD TV. Have tried every single possibility other

than BASE VIDEO-no Joy! This is NOT a Resolution problem, this

is a Video Driver Compatibility problem. Can Adjust

Resolution in BASE VIDEO Mode only! SHARP, COMPUTER CLINIC,

ATI RADEON, AMD, and even GEEK SQUAD, have reviewed and all agreed that this is a VIDEO DRIVER COMPATIBILITY problem.

They all also claim that it is not their problem to solve!

"Not all cards will support all Monitor Modes, not all

TV's will support all card modes...find one that matches

between the two". This must be classified Top Secret Info.

because multiple requests to SHARP, ATI RADEON, AMD, and even

MICROSOFT, for this specific information has been met with the

same answer. It is not their problem to solve, therefore it is

not their task to disclose this info. Info not available on the NET, not in SHARP Manual, not on SHARP Box, not on MICROSOFT WINDOWS 7 Customer Support, n-o-w-h-e-r-e! I have

repeatedly said, "Tell me Compatible Video Driver/Hardware/

Software with SHARP LCD TV LC-42SB48UT, and I will pay to have it installed"! SHARP doesn't even know! Their VGA Input was

installed to be non-compatible with ANY VIDEO DRIVER other than BASE VIDEO. BASE VIDEO is NOT a fully functioning VGA

input VIDEO DRIVER, therefore PC INPUT on SHARP BOX is

misleading. This is a severely restricted, severely conditional PC VGA INPUT. It is NOT compatible with 99.999%

of PC Video Drivers/Hardware/Software. It is only compatible

with a severely crippled BASE VIDEO Driver-and nothing else!

Your solutions have already been tried, and end up at brick walls. It is not for the lack of trying. I am still looking for Compatibility Software to make BASE VIDEO

remember previous Adjust Resolution Settings from previous

Start-up. If not, I am still looking for a Video Compatibility Driver/Software to replace Base Video for same purpose. Do

I have to write the Computer Code myself? It is the ONLY

Software that I have ever failed to find on the Internet, why

am I not surprised! Severely Limited PC Input IS

more accurate description on box, certainly with VGA. That

would certainly be a vital piece of info. not available!

Let others who read this Thread beware!

Base Video is a boot option for computer systems that are not working correctly. These do not set any mode or do anything special that you cannot do in normal mode from control panel. Which is why I'm baffled by the problems you're having...

 

 

Ok... now lets be sure what have you been setting *exactly*...

 

Start with a normal bootup on your usual computer monitor, forget Base Video for the moment, it doesn't exist...

 

In the Control Panel->Display dialogue you should set the resolution.

 

Then in Advanced Settings from that dialogue you set the refresh rate and color depth... for Sharp these have to be set to 60hz and 24bit color.

 

They default to the highest rates your *current* monitor will handle. Since the sharp is not Plug and Play you will have to set them manually.

 

Also... what model Radeaon Chip/Card do you have in your computer? And... are the drivers up to date?

 

I know this is terribly frustrating, but I'm betting that it's something quite simple, once it's figured out...

 

 

[Pettyofficer]

I am certain that it is terribly frustrating for you as well,

my apologies. Lets just say that I have been working on this

problem for the last three weeks. Lets just say that for the first 2 weeks, I never even heard of BASE VIDEO, didn't use

it, didn't even know how to use it. Two weeks in Normal

Boot-up, adjusting Resolution via ACER Monitor, Shut down,

connect VGA to SHARP, Restart Normal Boot-up, Sharp Screen

flashes "Not Supported". Shut down, connect VGA to ACER, Restart Normal Boot-up, adjust Resolution to next listed SHARP

Manual Setting via ACER......continue process over and over again. Resolution Settings tried this way under Normal Boot-

up are as follows:

1024 x 768 True Color (32 Bit) 75 Hz

1024 x 768 True Color (32 Bit) 70 Hz

1024 x 768 True Color (32 Bit) 60 Hz

1024 x 768 High Color (16 Bit) 75 Hz

1024 x 768 High Color (16 Bit) 70 Hz

1024 x 768 High Color (16 Bit) 60 Hz

1024 x 768 256 Color 75 Hz

1280 x 1024 High Color (16 Bit) 60 Hz

1280 x 1024 True Color (32 Bit) 60 Hz

 

These Adjust Resolution Settings were tried under Normal

Boot-up, and are available manually via ACER Monitor and

installed Video Card. They match specifically those Resolutions

listed in SHARP Manual. Contacted SHARP as to 16 or 32 Bit

(not listed in Manual of course). SHARP disagrees with you,

and specifies 32 Bit for SHARP LCD TV LC-42SB48UT. Every last

one of these Resolution Setpoints resulted in Sharp "Not

Supported" flashing on SHARP Screen. Tried 9 other different Settings that were variations of those above, NOT listed in

SHARP Manual (possible misprint in Manual). All having the

same negative result under Normal Boot-up. SHARP is a 42 inch

LCD TV Full HD with native Resolution of 1920 x 1080P. Video

Card is an Integrated ATI Radeon tm HD 4200 GPU, which supports D-Sub with max. resolution up to 2048 x 1536 @ 85 Hz. and lower. Video Driver Provider is ATI Technologies.

Driver Date-8/3/2010. Driver Version-8.762.0.0. Digital Signer-Microsoft Windows Hardware Compatibility Publisher. Windows 7

Automatic Video Driver Update specifies this Video Driver as most recent. AMD (Processor) has ATI Catalyst Video Driver

upgrades. Downloaded most recent one. Mostly has Video Graphics effects for Computer Games. Contains the exact same

Adjust Resolution App. as current Video Card. Made no difference with SHARP "Not Supported" screen. Removed ATI

Catalyst, and ALL ATI installation Software. Original Video

Driver remains. Double checked, still have "Not Supported"

under Normal Boot-up.

Finally, tried BASE VIDEO, first and only time that I

recieve PC Video on SHARP LCD TV. Any alteration of BASE VIDEO from there automatically defaults to "Not Supported" again. On

every Start-up with BASE VIDEO, Resolution Defaults to lowest

setting (640 x 480). Images become so distortedly huge as to be unusable. Forced to manually Adjust Resolution upon every

Start-up under BASE VIDEO-which is O-N-L-Y Mode that SHARP VGA

Input will function. Still looking for Compatibility

Software to maintain Resolution Setting with BASE VIDEO, or

Replace BASE VIDEO with Compatible Video Driver for SHARP

LC-42SB48UT to accomplish the same thing.

You wanted the LONG version, I was trying to avoid it.

I don't know what else I can possibly do to convince you that

this is not a Resolution Problem, but a Video Driver

Compatibility Problem. SHARP says that it is a Video Driver

Compatibility Problem, so does Computer Clinic, so does Geek

Squad, so does AMD, so does ATI, so does Microsoft. They have

the exact same information that you now have. Do you still

claim that you are correct, and that they are all wrong? I have spent three Replies struggling to convince you of the

exact nature of the problem. I am starting to think that if God came down from the Heavens with the perfect explanation of

the problem, you would reject it.

The REAL problem, apparently, is a complete lack of any

Video VGA Compatibility Standard for LCD TV. If SHARP VGA

Input is NOT compatible with any PC Video Driver (other than

BASE VIDEO Default), say so on the package! It might be also

helpful to mention this in the SHARP Manual as well. I find

the complete lack of this Info. as a tad bit too inconvenient

for me (meaning super hyper convenient for someone else- I

wonder who that could be?). Customers certainly have a right to know prior to purchase. Since there is no warning on the

Package, let this Thread be that warning. Let me do my part to

let the buyer beware of this deceptive practice. You want to

desperately find fault elsewhere, other than the Manufacturer,

despite the overwelming evidence from these Replies, I don't know what to tell you. SHARP Customer Support Lady tells me that she has to use BASE VIDEO, and reset Adjust Video upon every Start-up of her PC with her own SHARP LCD TV. Of course

you must think that she is from another Planet, or lying. Give

it a rest. You are not going to convince the whole Universe

that this is a Resolution/ Operator error problem. This is

simply a Manufacturer created Video error Compatibilty

problem. They do happen from time to time (shock! Surprise!).

No, they really do!
