Monitor/TV options for Sega Model 2/3 Emu

[Jollywest]

Ok I did mention my situation in the Scart topic, but thought I would be best starting a new topic as it has very little to do with scart now.

I am trying to get a decent medium resolution picture of a Sega Model 2 & 3 emulator via a powerstrip configured PC, on a CRT TV. The native resolution of these systems is 496 x 384 non-interlaced.

The best I could muster to get a full screen picture without interlace was 360 x 270 but the quality wasn't very good. Anything above this has an unwanted interlaced picture.
I realise the best thing to get native is to get a dual sync or med res arcade monitor, but is there any adapter or converter on the market that would get me close to the non-interlaced native resolution, that I could put into the CRT TV setup I have already?

A standard television simply cannot go above ~240-290 lines progressive (at 60Hz, you can go to a somewhat higher resolution if you decrease the refresh rate).  This is a limitation of standard definition television.  If you want to go higher than that, you have to interlace the video.  Simple as that.  No converter will get you around that.

Thought as much but thanks for confirming.

I have the opportunity to purchase a 31khz Nanao monitor at a reasonable price, has anyone here tried running Sega Model 2 & 3 emulators on one of these or any other 31khz monitor?  and if so, how did the games look?

Also, when interfacing this monitor to pc, do you just connect via vga cable? it has a vga socket on the chassis, but can this be connected straight to gpu (radeon hd 4670) and does the pc need to run any software to prevent any damage to monitor?

One more thing, the label on the back says it runs on 110vac, so to run off uk mains would I need a step-down transformer?
