Specs: Win7, 8GB
Got a HD6970.
Would it be more advantageous to use it's HDMI or it's dvi/dsub?
I'm using a TV as a monitor.
It's default resolution is 1366x768 but it defaults to 1280x720 cwhen using HDMI.
It can do 1920x1080.

I mostly do gaming.
Using 1280x720 does not utilise the fullness of the screen,neither does 1920x1080.

First of all LCD TVs are usually 16:9 screen ratio. 1280x720 & 1920x1080 are both 16:9. 1366x768 is some oddball resolution that is close to 16x9 but not quite.

What is the brand and model of the TV.

Graphics card drivers may have some 16x9 ratios resolutions available but wide screen computer monitors are normally 16:10 ratio.

I don't understand why 1280x720 & 1920x1080 don't fill the screen.

Do you have the latest drivers for your card installed?

What is the wattage capacity of your power supply ?

AMD Radeon™ HD 6970 Graphics

System Requirements


■550 Watt or greater power supply with one 150W 8-pin PCI Express® power connector and one 75W 6-pin PCI Express® power connector recommended
■Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products

If your power supply capacity is 500 watts or less, there's a strong chance the PS will be overloaded by the 6970's video chipset's current requirements when it's being loaded to the max, it will be damaged eventually, and may even fail completely.

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should have.

If you need to get a PS with more capacity, you can usually replace it with any decent quality standard sized standard ATX PS.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo (in quality) PS.
See response 3 in this:

I no longer recommend Cooler Master, AOpen, or Sparkle power supplies.
I'm now downgrading Thermaltake to middle of the road.
Antec has two lines of PSs - the better line has a longer warranty for the same or similar capacity - the other line is more towards middle of the road.
AMD has a list of Certified (tested and found to be good quality) PSs:

Note that if the display on the monitor or TV is LCD, or LED LCD, or Plasma, if you use the default Plug-n-Play monitor drivers for your monitor in Windows, you can choose settings that can DAMAGE the monitor's or TV's display !

If you load the monitor drivers for your specifc monitor or TV that probably came on the CD or DVD that came with the monitor or TV (or they can be downloaded from the manufacturer's web site), Windows will by default then display only the settings that both your monitor or TV model and your video adapter's specific video drivers support.

(Note that el-cheapo monitors, e.g. at least some Acer models, or TVs may not have any specific monitor drivers available - if so, be careful which settings you use with the default Plug-n-Play monitor drivers - consult the specs for the monitor or TV and don't use any setting that's not listed.)

Installing the specific monitor or TV display drivers may NOT set Windows to actually use them.

For info about making sure Windows is using them, see the info in this regarding using Have Disk with a CD or DVD, or pointing to a download you got from the web, to get Windows to actually use the drivers...

For Vista, or Windows 7....
See response 1:

An alternative that may or may not work, for 2000, XP, Vista, or Windows 7.

After the monitor or TV has been connected to the computer, use Windows Update (on the Microsoft web site in 2000 or XP) to search for Custom updates. If there is a Hardware update that lists your monitor or TV model drivers, if you install that, the monitor drivers will be installed AND Windows will be set to actually use them. You may need to Restart Wnidows in order for the changes to completely take effect.

"It's default resolution is 1366x768 but it defaults to 1280x720 cwhen using HDMI.
It can do 1920x1080".

"Using 1280x720 does not utilise the fullness of the screen,neither does 1920x1080."

The resolutions you can choose are determined by
- whether you have loaded the specific monitor drivers for the monitor or TV or not
- the specfic video drivers you have loaded for the video chipset.

See the manual for the TV - HDMI mode may not support 1366x768 .

You often have a different set of resolutions available after you have loaded the specfic video drivers depending on whether you're using a VGA, DVI, or HDMI connection. E.g. other tha HDMI may be able to support 1366x768

If you have loaded the default software installtion for the HD 6970 that includes Catalyst, you can probably fix the problem of 1280x720 ec. not fillling the screen with settings in Catalyst, IF and only if the TV's display supports that.

Catalyst requires that the Windows installation has .Net Framework 2.0 and it's updates installed in Windows.
If you install the software including Catalyst from the CD or DVD that came with the HD 6970, if Windows doesn't have it, it will probably be automatically installed from the CD or DVD as part of the software installation.
If you install the default drivers/ Catalast package from the web, it probably hasn't go the ability to install .Net framework 2.0 built into it, and you may have to install that.
If .Net Framework 2.0 has been installed, it's listed in Control Panel - display as large icons or small icions - Prgrams and Features

(Installing a higher numbered version of .Net Framework does not eliiminate the need for having a lower numbered version installed - they're independant of one another.)

Hi OTH :)
Nice to know your still around.

Latest 12.1 drivers installed.
I also don't understand why it does not fill the screen?
There is an option in CCC called underscan/overscan which can 'stretch' the screen to the edges.
This causes a few problems in games with the mouse location being off.
TV is a Panasonic Viera TX-32LMD70A,quite old really.

I know ;)
TV only has a dsub and HDMI,card has DVI was using a convertor to dsub.
Now using the HDMI.

I have antec quattro 1000w.
I don't think there are any specific drivers for the TV?

Is there any performance gains when using 1 over the other when gaming?

Below are a number of links. First link is to the specs of your TV.

The specs do NOT state the native resolution is 1366 x 768. That is the total number of pixels. Not the same thing necessarily.

Your TV is only capable of displaying XGA & SXGA computer signals. See the links below to see what those are. They are 4:3 ratio resolutions so they are not going to fill the screen. Should have bands on each side.


Number of Pixels: 1,049,088 (1,366 x 768) pixels
Applicable PC signals: XGA (SXGA compressed)


So, in the end if you are displaying any Wide Screen resolutions you are getting more out of the TV than the specs state.

Applicable PC signals: XGA (SXGA compressed),does this only pertain to the dsub input or does it mean what is 'sent' from my pc?

"Screen Aspect: 16 : 9 Wide" shouldn't this be available with HDMI?
Unless the 1st statement covers this.

I am using HDMI at the moment and yes,there are 2 bands,1 either side and a small band on the top,I can live with this.

I interpret it to mean that is what the TV is capable of displaying when being fed a signal form a Graphics card.

Your TV has 1366 pixels horizontally and 768 vertically. Maybe I don't understand how this works but if you attempt to use a resolution that is less than those numbers in either direction than either the picture is going to be smaller with banding, or it will extrapolate by using one pixel to serve for two or the opposite. 768 - 720 leaves 48 pixels.

Either way I think 1280 x 720 should give you the sharpest picture but there will be banding on the sides. 1366- 1280 leaves 86 split left and right.

Same principle works vertically.

If you want it to work full screen I think you will need to get a new TV/monitor. Another issue is that your TV may not have a fast response time. I don't see anything in the specs for that.

Where are you located? That TV was designed to run on 240V@50Hz.

"TV is a Panasonic Viera TX-32LMD70A"

Apparently it's not a Panasonic USA model
Most of the people who start a subject (discussion) here are in the US. If you're NOT in the US, or if you didn't buy the subject hardware in the US, you should say so.

Panasonic TX-32LMD70 - 32" Widescreen Viera HD Ready LCD TV


Technical Details

32" LCD widescreen TV with Freeview and advanced 3D colour management

Ultra wide 178 degree viewing angle (horizontally), resolution 1366 x 768

That's on a UK site. Apparently it's sold in the UK.

Support for it is on the Panasonic UK and Ireland web site:

There are no specific monitor drivers for it.
The only download available for it is the Operating Instructions Manual


Page 13 - Change aspect ratio

Try setting that to 16:9 when you're using the PC display
Also see page 44, and the page 44 info below.

page 39 (also 40, 41)
HDMI Functions

Use with a PC is not assumed

= it might not work properly with a PC.

We have seen that some TVS will NOT display a PC display properly via a HDMI connection. You may need to use a VGA or DVI connection.

Technical information
Aspect Ratio

PC input can be set to 16:9 (widescreen; 1.77 horizontal to 1 vertical) ) , or 4:3 (for legacy TVs and monitors; 1.33 horiziontal to 1 vertical).
If it's set to 4:3 (= 16:12) , a widescreen image from the PC ( e.g. a resolution that has a 16:9 ratio) will have black bars where there is no video, and the image will be squished - out of proportion - horizontally.

Page 46
Technical Information
PC connection

Max vertical refresh rate at 1366 x 768 is 60 HZ
- That setting can't be higher than 60 HZ in Windows

page 51

PC signals - VGA, SVGA, XGA, SXGA (compressed)

WXGA is not mentioned.

That doesn't match the info on page 35 and 46.
You MAY need to use a resolution that has a 4:3 aspect ratio in Windows, e.g. 1280 X 960, and set the Aspect ratio on the TV to 4:3 when you're viewing the PC's image.

Thanks for the info guys :)

Yeah did wonder about refresh rate?
I'm in UK.

All seems fine running at 1280x720.
Was just wondering which would be best to use?
1366x768 through dvi/dsub
1280x720 through HDMI?
analogue v digital,which is better for gaming?

I thought I covered that above with my opinion. That said, I suggest you try both.

I don't know if 1366 x 768 is an option in your driver list of resolutions. If so, that probably would be best.

We on this side of the pond are not familiar with anything other than NTSC. Your TV is designed to be used in multiple countries and has the following capabilities: AV-NTSC: PAL-525/60, NTSC, M-NTSC.

When feeding the TV a normal broadcast signal you would be using the appropriate version for your area. When gaming from a computer you are sending a different type of signal. I am not sure if the aspect ratio settings in your TV controls have any affect when feeding data from your computer. You need to experiment.
