Even a fleet glance is enough to see that Palit's card is customized, while HIS' card copies the reference design (but it's still manufactured by HIS). The product from Palit offers all possible connectors that have been designed for graphics cards. Besides, it comes with an HDMI-to-DVI adapter, so that you can plug two LCD monitors via DVI.
The card from HIS has an original TV-out that requires a special adapter to output video to a TV set via S-Video or RCA.
An analog monitor with a D-Sub (VGA) interface can be connected by means of a special DVI-to-D-Sub adapter. The bundle also includes a DVI-to-HDMI adapter (these graphics cards support video/audio output to HDMI receivers), so there should be no problems with such a monitor.
Maximum resolutions and frequencies:
- 240 Hz maximum refresh rate
- 2048 x 1536 x 32bit @ 85Hz Max - analog interface
- 2560 x 1600 @ 60Hz Max - digital interface (all Dual-Link DVIs)
As for HDTV, a review is available here.
All these cards require additional power sources, so each is bundled with a molex to 6-pin adapter, even though all modern PSUs have such cables.
