Poor resolution on pc-tc setup

August 23, 2011 at 10:42:58
Specs: Windows 7
I decided to hook up an old desktop to the tv in my bedroom to watch movies - but the resolution is terrible. My pc is connected by a dvi to hdmi cable to the tv

The specs are:

TV - Toshiba 19BV500B

PC: Dell Dimension 5000

Processor 3.00 gigahertz Intel Pentium 4
Windows 7 Ultimate
2 gb ram
Radeon X300/X550/X1050 Series (Microsoft Corporation - WDDM) [Display adapter]


All drivers seem up to date. The resolution is set to the recomennded setting 1920 x 1080.

The TV is set to its 'PC' setting - which just resizes the screen to make it all fit - but the resolution is still terrible,

Watching video files is fine - the problem is with the look of windows and browsing - text is tiny and blurry/grainy


Any ideas?

Cheers

READ the MANUAL for the Toshiba 19BV500B !

It probably tells you what the resolution should be set to on the computer for the TV display when it's being used as a computer monitor.

"The resolution is set to the recommended setting 1920 x 1080"

Your TV's "native" or "optimal" resolution is 1,366 x 768 !

All LCD (and Plasma) displays have a "native" or "optimal" resolution specified for them.
If you use any other resolution, the display will NOT look as good, the most noticeable thing being the text on the Windows screen will NOT be as clear.

If you can't choose a resolution for the TV display on the computer that is 1,366 x 768 or whatever the TV manual tells you it should be
- to get the proportions correctly, choose a resolution that has the same aspect ratio as the TV for the display on the TV - 16:9 (the ratio of width to height - 1.777 when you divide the first number by the second one)
- Turn on Clear Type in Windows XP or Vista or Windows 7 - makes type/fonts on LCD screens look clearer.

.........

In Windows 7 or Vista
RIGHT click on a blank part of the main desktop screen, choose Personalize, then Display Settings.
One of the display icons is for the settings for the computer's monitor, the other one is for the settings for the TV.
You click on the icon for the display you want to set settings for before you do that. By default the settings for the primary display, the computer's monitor in this case, are shown.
In your case, I suspect the resolution for the computer's monitor should be set to 1920 x 1080, and for the TV's display should be set to 1,366 x 768 .

Hi,

The 'recommended' resolution was just what windows told me when i right clicked on the desktop to set the resolution.


I changed the resolution just now to 1366 x 768 - it is still quite grainy and the picture size is pretty small - massive black bars all around.

I can

The quality is no better than when I had it going into an old crt downstairs using an s-video cable - was buying the dvi - hdmi cable a complete waste?

Hi,

I turned on clear type and windows keeps telling me that the native resolution is 1920*1080.

Also, at 1366 x 768 - the bottom half of text boxes disappear and it becomes unusuable

READ the MANUAL for the TV !

"I turned on clear type and windows keeps telling me that the native resolution is 1920*1080"

That's for the computer's monitor, NOT the display on the TV !

If you're setting the computer's monitor to 1366 x 768 , the text on that monitor probably WILL look crappy !

See the last part of response 1 !

There isn't a separate monitor - just the pc hooked up to the tv.

The manual doesn't provide a native resolution - it just gives a list of supported up to a stated maximum of 1600 x 1200.

"My pc is connected by a dvi to hdmi cable to the tv "

How long is the cable ?
You WILL likely have problems if it's longer than, say, 12 feet - 4 meters.
......


"There isn't a separate monitor - just the pc hooked up to the tv."

In that case, where are you getting this from ?

"The resolution is set to the recomennded setting 1920 x 1080"

If you quoted the right TV model that can't be right.

.....

"The manual doesn't provide a native resolution - it just gives a list of supported up to a stated maximum of 1600 x 1200."

The manual for the monitor ?

The stated max resolution in the monitor's manual is usually the same as the "native" or "optimal" resolution for an LCD or Plasma display.
If "native" or "optimal" resolution is not mentioneed then it's "native" or "optimal" resolution is probably the max resolution.
1600X1200 does not make sense for the monitor model you quoted. .
..........

" I turned on clear type and windows keeps telling me that the native resolution is 1920*1080"

That doesn't make any sense, unless
- you quoted the wrong TV model and the the native resolution is 1920X1080 for it

- you quoted the right model but have the resolution set to 1920X1080 in Windows and the message is being generated by the TV itself and it does NOT say native - you're being nagged by the TV to change the resolution.

1. How long is the cable ?

The cable is 2m.

2." There isn't a separate monitor - just the pc hooked up to the tv."
In that case, where are you getting this from ?
"The resolution is set to the recomennded setting 1920 x 1080"
If you quoted the right TV model that can't be right."

Like I said - I'm getting this by right clicking on the desktop and selecting resolution - windows is reporting that 1920x1280 is "recommended".

I have a pc hooked up by a dvi cable from the video card to a tv. There is no second monitor.Just a tv.

3. "If you quoted the right TV model that can't be right"

I'm quoting the right model - I know how to get a model number off the back of a tv...

4. "The manual doesn't provide a native resolution - it just gives a list of supported up to a stated maximum of 1600 x 1200."
The manual for the monitor ?"

There isn't a separate monitor - just a TV. Regardless - the manual for the TV just gives a list of supported resolutions.

http://www.hdtvreview.com/pdf/toshi...
pg 28 (appendix A) PC Input typical display modes...."This display has a maximum resolution of 1600 x 1200"

5. "" I turned on clear type and windows keeps telling me that the native resolution is 1920*1080"

If I change the resolution in windows to 1366 x 768 resolution, then turn on Clear Type, I will get an indication saying "your display is not set to its native resolution" It will then give me an option to change to 1920 x 1280.


6. "you quoted the wrong TV model and the the native resolution is 1920X1080 for it"

No I haven't.

7. "you quoted the right model but have the resolution set to 1920X1080 in Windows and the message is being generated by the TV itself and it does NOT say native - you're being nagged by the TV to change the resolution."


Windows says native. And recommended. This is all in windows - nothing is appearing on the tv about resolution.

There is no support for 19BV500B on the US Toshiba Support site.
I found support for it on the Europe - UK Toshiba Support site.
(Apparently it's under Discontinued models)

You probably MUST set the display for the TV (PC monitor mode) on the computer to 1366 X 768 !

19" BV series with HD ready screen and Freeview
19BV500B
http://www.home-entertainment.toshi...

Key specifications:
Resolution: 1366 x 768

Specs tab

Screen Format 16:9 (= the aspect ratio - the ratio of the width to the height of the physical screen)
Resolution 1366 x 768

50Hz processing
............

Brochures and Manuals tab - wrong manual
........

The right manual (the same one you pointed to) is under Brochures and Manuals tab, in the wrong place, here:

19" BV series with HD ready screen and Freeview
19BV501B
http://www.home-entertainment.toshi...

http://www.home-entertainment.toshi...

Page 7 (of the pdf) - ports - HDMI and VGA for a PC connection.

Page 8 - Connecting an HDMI or DVI Device...

On the left it says you may need to use a better type of HDMI cable.
That probably also applies to a DVI to HDMI cable..

"The cable is 2m"

Good.
On the right side of that page it says the cable should be no longer than 2m.

Page 9

"To use a PC, set the monitor output resolution on the PC BEFORE connecting it to the television."

You may need to temporarily connect another monitor.

Page 27 - PC Mode

You may need to tweak the settings on the TV to get the PC display on the TV to look the way it should.
..........

Since it doesn't have a DVI port, if you can't get the display on the TV to look good with the DVI to HDMI cable, you could get a better DVI to HDMI cable, or you could use a DVI to VGA adapter on the computer's DVI port and connected a VGA cable (male both ends) to the VGA port on the TV - that will probably display fine !
.............

"windows is reporting that 1920x1280 is "recommended".

That doesn't make sense unless you have previously loaded drivers for some specific other monitor that DOES have a 1920 X 1280 "Native" or "Optimal" resolution.

RIGHT click on a blank part of your main desktop screen, choose Personalize, then Display Settings.
What does it say there ?
What monitor on (the name of your display adapter) ?

As you found in the manual on page 29, the TV's max resolution is 1600 X 1200 - it can't support 1920 X 1280 !!

It will have crappy looking text at 1600 x 1200, that's NOT a 16:9 ratio so the proportions of what's shown on the screen will NOT be correct, but it's supported.

It also says on Page 29

"Your TV may not support different resolutions. Supported resolution modes are listed below.
If you switch your PC to an unsupported mode, a warning OSD will appear on the screen."

OSD = On Screen Display

" a warning OSD" - in other words the TV itself will display a message about the resolution being wrong !
