I just used a DVI to VGA cable to connect my Vivio 37" TV to my computer ...Will I be able to watch HD DVD and Blueray through this cable?

Providing your TV allows you to input 720 or 1080p via VGA yes.

Thanks for the reply Nety...So I need to look at the owners manual that came with my TV...Providing it does then there would be no point in trying to connect the TV with HDMI? My video card has a HDMI port but I can not get the resolution right....Any more advise would be appreciated....

You may have issues getting HD video with HDCP flags on through that cable - HDMI would be the best if you are primarily looking at watching video? Both Nvidia and ATI cards have scaling options you can use

Definitely use HDMI.

What's the actual issue you're having with the resolution? Are the edges of the screen disappearing off the edge or things look a little blurry?

You may need to muck around with the overscan options in Catalyst Control Center or check that connections settings in the TV (i.e. check if theres a PC mode). If there is a PC mode on your TV you'll likely need to set the overscan to 0 in CCC.

I would seriously look at the manual for your TV to see what the actual resolutions and refresh rates are as well. My 1080p TV native resolution is actually 1920-1200 (not 1080) and I was losing pixels off the top and bottom of the display when using 1200. With the overscan options in nVidia's (had to use a registry hack to bring this back, wtf nVidia!!!!) control panel I got it working properly (i.e. the resolution was 1920-1200 but windows only had 1080 to use).

That vid card looks fine, is HDCP compliant and all that, so you should persevere with HDMI connection.

The egg shape is a sure sign of incorrect aspect ratio, so you likely have the resolution, scaling or overscan incorrect.

PC mode on TVs usually turns off any scaling by the TV itself (i.e. tells it to accept the full scan from the source and not apply any 'intelligent' scaling).

What is the model Vizio (Vivio?) is it?

VO37L is 1366-768 47.7h-p 60v-n @  85.5mhz
VW37L is 1366-768 47.55h-p 59.81v-p @ 85.5mhz

Its a Vizio VO37L...I was wrong no PC mode...Just says "same settings for PC as TV " when its talking about settings... Thanks for your help..Im going nuts trying to figure this out...I got it connected with the HDMI again..Actually I have it DVI to HDMI..I have an HDMI to HDMI I can use if I need to ..What do you think? ...Gonna play around with ccc somemore...As crazy as this sounds I can update the drivers for the card but it seems like that puts me further from wehere I want to be than B-4..I uninstalled everything then just installed the disc drivers..Think I need to go ahead and download them again? I know that sounds like a crazy question,so I will be in the process of that also...

You definitely want to use a newer driver. The one that come on the cards disk will be woefully out of date. The newer drivers will have many bug fixes and updates for AVIVO (hardware accelerated video decoding), which you'll want if you're using this to watch videos.

In general with modern flat-panels, they'll provide the source with capibility information. The resolutions available in CCC are probably those provided by the display.


To start with reset everything back to normal. Switch to HDMI. Update to the latest ATi drivers.


Now check what it looks like going out at 1366x768.


Does the screen go off the edge?


Is the screen distorted?


You can try setting a customer resolution (not sure if CCC has this, nVidia does) using the exact timings from your TVs manual.


You can try the overscan options in CCC as well if the screen goes over the edge of the display.

Ok did all of that...don't have a setting for 1366x768...It does have a 1360x768 and its distorted and a little smaller than the screen...I don't know what it means but I can only use that setting with 16 bit color.Will not let me set it to 32 bit..This stuff must be over my head..

You are pretty close grasshopper - I know how frustrating this can be. Your card should easily output in a higher resolution than that, sounds like a potential driver issue?

Was this after you installed the newest driver?

If it is then damnit!!!! This was a limitation of the older Radeons, didn't think it would be with the Radeon 3x00 series. They had a limitation that where they were limited to multiples of 8. Rediculous.

I just had a look on my wifes computer (she has a Radeon 4870) and in the CCC there's a section under the display (in my case called Digital Panel (DVI) 4) called HDTV support. Under there is a section called HDTV support. In there is options to add all the HDTV formats to the Display Manager (i.e. available resolutions). Give this a try.
