PCIE Wide Screen video
« on: January 05, 2018, 04:10:00 pm »
Are there any video PCIe video cards that  can do 1920 x 1200 resolution?

In a PCI Express ×16 slot the ATI FireMV 2200 works here in this resolution. Every other ATI card should do the same using a DVI connection.

I don't know, what you mean by the term "video cards" perhaps a frame-grabber or some other form of digital video input (without audio)?

Yes, I have the resolution 1920x1200 on my graphics card:
RV610 [Radeon HD 2400 PRO] , ($94C3)

Any with enough memory (128KB?) should be able to do it. The problem is having it listed in the video BIOS. With Panorama, you can force it to use the wide screen resolution and with SNAP, you can patch the BIOS and replace a resolution with 1920x1200.
For SNAP this worked here to force 1680x1050. Forget where I got it.

As Dave and maybe others already wrote: There's usually no problem to get that resolution. Panorama supports what the BIOS supports in VESA mode. Most BIOS versions support 1920x1200, also with digital output.

If you want accelerated graphics, then you're limited to SNAP and older hardware, mainly ATI, up to Radeon X750/800/850. Also the X300 card works well with SNAP, but performs much worse than the formers.

Summary: You don't need anything special for that mode. The on-board graphic suffices, if the BIOS supports it.

I have seen new video card (graphics cards) that only have a few vesa modes. One is the GeForce 710. A Radeon HD 6450 has 1920 x 1440 but does not want to allow 1920 x 1200 with Panorama. What I was wondering is if there are any "new" cards that have a PCIe bus and will display at 1920 x 1200. I have have many older cards that work with Snap and Panorama. Does anyone have actual experience with a card that is still being manufactured?

I found in my collection of hardware a Radeon X800 which was never used. Still in the box. That works nicely in 1920 x 1200.
Now, I would like to install more machines. So any suggestions?

The old hardware, such as your X800 or my X850 TX PE can still be found (old AND brand new) on eBay...so given that these chipsets are literally at the 'top-end' of what was cutting edge and supported by SNAP, why not simply buy the stuff you need and know will work, instead of taking a chance on brand new hardware?

Further on, my suggestion is based on the fact that, at least in my case, the Panorama drivers even for a well known chipset like the X850 are completely un-accelerated. We are talking here molases slow...and for Desktop use, where screen re-draw speed matters (think something as simple as web-browser) I am simply not going to trade the speed of something like SNAP for a VESA/BIOS based display on a new video hardware.

Here are some details (tested using Sysbench 0.9.5d):

The graphics card is now on the CPU chip for most Intel computers. But it isn't faster than the Radeon 850, except if you want to use DIVE (like for Firefox or something). I think these are Panorama. SNAP would not be accelerated for these machines.
