Video Card Recommendation

[khoffman74]

Does anyone have a video card recommendation for the following setup:

Dell Inspiron 560 desktop (medium tower) with an on-board Intel GMA X4500 video card (1600 x900)
One HDMI output converted to RJ45 (Cat6) (for distance) converted back to HDMI going to three HDTVs
Output resolution wanted: 1920 x 1080 HD

The stock card is 1600 x 900 which is too small for the monitors. However, I've tried using aftermarket cards like GEFORCE GE 610 which work for a little while then flicker and finally die. I've also used higher-end cards and they don't work at all ( the 300W power supply on the Dell is too weak possibly?).

So I guess I'm asking for a recommendation on a video card that can drive two outputs, one at 1600 x 900, one at 1920 x 1080.

On 1920x1080 screens (full-hd), I often use the 1280x720 resolution (HD ready). I don't know how big your screens are and from what distance the content is viewed but 95% of the time you won't be able to see the difference between 1920x1080 and 1280x720 viewd on 1920x1080 screens (they are just too far away to see any difference).

I have used the CAT6 technic with splitting to other screens to at some of my customers. Another benefit of using the 720P resolution (1280x720) with this hardware is that this resolution will go over much further distance over CAT6, than the 1080P resolution (the data density is lower). This will result in better quality pictures on 720P resolution than on the 1080P resolution, thus making the lower resolution even sharper and better than the higher resolution!

Ofcourse, screaming terms like: we play FULL HD, and other bla bla bla is good for selling, but it does not have to be better (you need faster hardware, often that wil get hotter, consumes more power, etc etc, while most of the time people are not able to see the difference). Well... this is my experience.
